do they make superchargers for 240s? even if they do is it any good for the ka?

They don't make kits, but you can always put something together yourself, but seriously, just turbo the damn thing, it's the easiest way to get KA power.

well it wouldnt be bad. Forced induction is forced induction, your still going to scoot out of town compared to the NA. As far as i know there is no super charger kit, but i dont research for superchargers. Turbo is just more easily done and common. Plus i think a turbo is more efficient for a 4 banger. I mean to power another pulley on a super charger with a 4 banger.....it can be done of course but turbo would just be an easier route to go.

i wouldn't boot out that SC idea that quickly... i mean if you can get a good setup down ... then the the dependability and reliability will exceed a turbo setup. Sure it won't have the peak power but it's stable and 90% of the time you won't have to worry about pipes blowing and many of the common overheating problems.

it won't be utilizing the ka to it's full potential, but it'll definitely have decent power to get you around on a daily car (for many of us just looking for more safe power and not a full track/drag setup).

If you find a way to strap a Roots on there its gonna choke like a t25 on the top end.

If you put a centrifugal on there its gonna have a B16 type powerband.

If you put a T28 on there it will be Spooled by 2500RPM and make around 300 WHP.


theres no logical reason not to go turbo, even on a daily a supercharger has the potential to have just as many if not more problems as a turbo kit.

everybody says the Roots aren't good for top end... I beg to differ

I've driven a few roots blower equipped cars, and they were all different engines... they all had great top end pull........


SVT Lightning
Ford Supercoupe
Pontiac GTP


the pontiac is pretty cool because its one of the only FWD cars I know that will light up the tires from a roll when it downshifts into 1st gear muahhahaha. I bet a new Maxima could do it though.

a roots blower pushing 7-10lbs of boost on a KA would be awesome, and yes you can even run an intercooler on a ROOTS blower, some people only think that a centrifugal supercharger is the only one you can intercool. The Ford thunderbird Supercoupe comes from the factory with a M90 roots and an air-air intercooler. If you wanted to run a water cooled setup it would be even easier to setup.

now if you wanted to run 20-30lbs of boost I'd say get a turbocharger defintely.

Roots blowers and centrifugal superchargers both take some power to run, but so does a turbocharger.....

The way I see it is that roots blowers will be more suitable for higher displacement motors since their high displacement gives them some low end torque to play with so the engine can haul an oversized roots up to speed. On a 2.4 a small roots should make good power down low but I think a roots blower thats gonna flow enough at 6500RPM is gonna make the engine a dog down low. where it basically becomes a somewhat less peaky centrifugal.

Also, this guy isnt SVT. and he wants a street setup. why bother spending time and money fabbing up brackets and piping and sizing compressors when there are turbo kits that would cost as much or less and make more (and Better) horsepower?

good points. But i would have to agree with r.w. I mean turbo 4's are just hand in hand. They go way back.

i love the sounds of a nice S/C. Why do you guys say they are bad for 4bangers? What about all the S/c's for honda and acura engines that have been successful? And those are only 1.6 and 1.8L mostly, the 2.4L KA should have some nice power to it..id love to see a S/C kit for the ka, pretty different

Those kits give a small boost of power over a linear powerband, but you won't see any kind of a performance Honda (I know it sounds weird) with an SC, it's just very mild street setups.

Roots=60% efficiency at best
turbocharger=80% efficiency at best

Who wants 20% less heat and room to install an intercooler?

Plus there is absolutely no market for a supercharged KA. Maybe KA-T is the bandwagon now, but at least you have a selection of parts.

honda's have s/c kits because the maker of these kits well alot fo them is comptech[i think], which started off as a honda supplier, before the brannch off

they use s/c because for small power boosts they feel better to regular drivers as the powerband is smoother

s/c are less efficent for small motors, because they draw off more power than they give back at certain points on the power curve, turboing is also just easier, but in the end it will come down to what you want, i mean the way you setup it up may be different and the s/c may be just as good as a turbo and vice verus

Best thing about a turbo is no changes need to be made to turn up the boost. Until it maxxes out, that single turbo will keep pushign more air. With the common T3/T04E, you can push enough air to make 400whp before needing to upgrade. At that point, don't expect something that drives as smooth as when you bought it. And the powerband can be very smooth as well. Tuning has a lot to do with how smooth your powerband is.

Agreed supercharger kits are a good deal for someone who want a little kick that IHE can't give them.

fanat you can probably explain this.

why are centrifugal SC's not fixed-dislacement i.e. they do not push a fixed volume of air per rotation? is it just they are more effecient when they are spinning faster? if so how?

Just because they have been "successful" on honda's doesn't make them a good alternative to turbo. Take Vortech for example, I read an issue of honda tuning a while back where they installed a Vortech supercharger on their teggy GSR. It got good power gains (somewhere around 90hp) but their quarter mile time was only decreased by about half a second. Not really worth the $3,000 price. Turbo is much cheaper and you see real improvment in quarter and laptimes.
Turbo is definately the way to go on a KA.

because they don't know what they are talking about LOL

plain and simple

its obvious they are only making their statements from magazines and shit and never actally driven a supercharged car.......

oh and the down low power making ability of a ROOTS blower will stomp a turbocharger, it will make boost sooner, and act as a displacement increase on the engine... we all know what that does hopefully by now....
Turbochargers are peaky, and 7psi is 7psi of boost, no matter if its from a roots or a turbo... the roots will make power faster then a turbo would.

also I only know of one turbo kit for the 240sx, thats a s14, and its like 3-4 grand isn't it? Does that even include everything you need to bolt it on? it doesn't look like it does to me....

its actually harder to put a turbo on a car then it is a supercharger, and involves a lot more parts and lines.

because they don't know what they are talking about LOL

plain and simple

Who doesn't know what they're talking about?

My girlfriend has a 02 mercedes-benz c230 sports coupe and it has the roots type s/c. And its fast as hell even with all that weight. And the top end kicks ass 0-130 with no hesitation its just goin thru gears like it's cool.

7psi of boost is NOT 7psi of boost. 7psi of boost on a T25 is equal to about 3-4psi of boost on a T04E. Then 7psi of boost at 70% efficiency will make much more power than 7psi at 50% efficiency. PSI is a bad way to rate power period. Flow is always the determing factor in how much power you make.

Centrifugal compressors (dynamic) aren't fixed rate because they flow different amounts of air depending on impeller speed. Tehy are basically belt driven turbochargers. And in most cases, they are geared.

Since we are talking modified cars, who uses 1-3k for racing anyways? I'll happily take my 4k spool with a nice pull all the way to redline over a 1k 7psi anyday.

Turbos aren't peaky at all if they are sized right. The common T3/T04E 50trim turbo has a very very smooth powerband. Some would say my turbo is peaky, but I chose it to be peaky.

Turbo kits for the KA:

www.phatka-t.com
www.boostdesigns.com
www.fmax.com
www.nsport.com
www.realnissan.com (IDK if that one is still around)
www.greddy.com
and its not that hard to put one together. Install is easy...

Nope, never driven a supercharged car. I've ridden in one. Feels like NA to me.-=P

roots blowers are defintely the way to go if you wanted to make ultimate power, But to do something of that magnitude on a 240sx, I have to agree it would be easier to turbocharge it given its engine configuration.

A supercharger is not a bad idea for someone with a daily driver 240sx that only wants 5-8 or so psi of boost and doesn't want to do a forged engine rebuild......
it is also not that hard to fab up supercharger parts... even a bracket for the pulley and blower would be way easier to make on your own then a tubular custom turbo manifold. Cutting out a plate of metal is not even in the same ballpark as welding up a header like that on your own. Unless its your professional job. Adapting the intake manifold to the blower would be a hard task that would require some mechanical and customization skills. It would not be as hard if you used the stock intake manifold, the blower would basically replace the plenum.

let us not forget the fastest drag cars use Roots blowers.... =) I just know most people here hate the thought of V8 power and Top Fuel cars so my flame suit is all zippered up!



*edit

there is nothing wrong with NA power, in fact its the preferred method of power delivery for grip racing..... how many Sprint Cars/Nascar/F1/IRL/KART/Speed world Challenge/JGTC/Rolex/Lemans cars do you see using forced induction these days?
:rolleyes:

Ight, now we're on the same page.lol

One arguement I will make in terms of the top fuel comment is they rebuild their engines after every race. Detonation isn't an issue or something.lol But they end up dieseling at 1/8mile. Another reason they don't use turbos is that there is a weight penalty for turbocharged cars. BAck in the day, turbo and supercharged (same car.lol) wasn't uncommon. Roots blower for off the line and turbo for top end.

why are roots better than twin screw SC's?

and SC install can be way easy or not depending on how they are lubricated, some have self contained oil systems, some you need to tap into your oil pan and run lines. but if you want to buy everything in a kit, right now you are looking at turbo.

and F1 had turbo, i believe maybe 20 years ago they were all running turbo inline 6's

^yup. F1 pulled turbos from competition because the cars "went too fast,"

Fucking racing is doing the opposite of evolving anymore. F1 is contemplating going to all V8s. Nascar runs restrictor plates. IMO, the organizations are too involved in the sport. Only restrictions should be displacement, FI or not, tire size and weight. After that, fiddle and fuddle around and whoever wins wins.

That wouldn't fair because the team with the biggest budget would win every race. And the reason for the change in the F1 is because the races are fucking snore fests, there's like 3 passes in the whole damn race, they think that making the cars slower will make it easier to maneuvre, therefore pass.

ummm sorry to ask but what are the ROOTS you guys talking bout? i've never heard of it?

roots is a style of supercharger developed by some guy last name Roots from indiana in like 1887. there are 2 impellers that move air into the intake system. makes a lot of heat, not terribly efficient.

anyways FANAT I AGREE 11110003003% fuck all those rules. i think actually what they are doing now is restricting downforce more which might make for more action (in f1). like passing and shit. but this guy i work with was telling me about F1 when they used to have turbos and how much cooler it was. i believe him. i love turbos. make f1 more exciting. fucking stupid ass rules. HWERES THE NISSAN F! CAR GD IT> SHIT.

turbochargers actually make more heat because they are already running off the extremely high EGT's on a forced induction car....


supercharger is belt driven with no hot exhaust..........


also how would a lubricated supercharge be that hard to set up? You would have to do all that stuff on EVERy turbo if not more.......


the time when turbos ruled f1 was 25 years ago when engine building was no where near what it is today........ there is simpy no need for turbos today in professional racing, they get by with bigger engines and more displacement.. it seems to be the trend.

Like money is an issue with most of those teams anyway.....

There is more heat generated in a roots type supercharger than a properly sized turbocharger. Exhaust heat transfer is very minimal. The compressor side of the turbocharger is insulated from the exhaust side. To play the devils advocate and say that heat is more of a problem with turbos, well, can you say intercooler? Higher efficiency=less heat. Unless its a lysholm compressor, turbos win.

I don't watch F1 to see who will win, I watch it to see how fucking fast and incredibly manuverable the cars are.

roots blowers are defintely the way to go if you wanted to make ultimate power


Wait, so is that why the Nitrous and Blower Guys are getting pissed because they're letting turbos in and getting stomped?


Top Fuel cars use Roots because
A) its in the rules
B) The Exhaust is too hot and melts turbines.

Why dont they use turbos? because turbos are most definately a power adder the also mask problems in engine tuning, sanctioning bodies outlaw them to slow the cars down and make the teams work for their money, Also last I checked most Lemans cars are turbo.


Superchargers blow cooler because they're less effecient? wait no, they blow hotter becuase they are less effecinent. roots operate around 60% effecincy as opposed to some turbos running up in the 80s heat transfer from the exhaust can only account for a miniscule amount of heat when the air is traveling at near Mach.

telling us we are getting are info from magazines and then regurgitating every lame peice of info in evrey article Ive ever seen? Wow thats cool.

Thats also cool that every time some Roots or V-8 guy gets stomped in an argument thats completly unrelated they say "well you just dont like V-8s" I dunno about the rest of us but Im lovin the LS6, VK45, The New F1 V-8 that churns 22K you keep on thinkin that just because I dont like some lame Econodog 350 the only engine I bow to is the B18C1

:gay:

I'll counter with this statement if we are asking for proof


please show me some scientific proof as to why air compressed in a supercharger is hotter then air compressed in a turbocharger, Id love to hear this one.......and Im not being a smart ass, if you know its different please correct me with viable information.

and uh.... intercooler can be run on a roots blower too. I thought you might have read my previous post where I talk of a OEM car with a intercooled roots blower.

and don't take such offense and start flaming me for my V8 comment, it was a general open coment, nowhere at all was it directed at you, yet you had to come at me with the attacks......hmmmmmmmmm

don't feel so offended

also RW.... your just backing up my statement on Top Fuel Cars, even if it wasn't the rules LOL

the turbos can't take the heat and make that much power, the fastest cars in the world all have Roots blowers..........

am I right or am I right?


Last time I checked the ROlex Lemans series the winning cars were using N/A C5R Chevy motors.....not turbos

Okay, we all know compressing heat makes air hotter. Enthalpies correct? Internal energy of a working fluid. SOOOOOOOOOOO::

Take the temperature from compressing air(IAT) and divide it by the comressors efficiency.

say IAT=200f

200f/.7=285f since most turbochargers nowadays operate at at least 70% efficiency

200f/.6=333.3f since the best you can really get is 60% efficiency out of a roots.

Not to mention most if not all performance application turbocarged cars run intercoolers. 70% less heat with the turbo so make that 200* NTM if they use meth/water injection. Being as though all roots blowers can really do for itake charge cooling is meth injection.

Trust me, and hugh macinnes, and Corky Bell, roots blowers blow hotter air than turbochargers given boost pressure is the same.

please show me some scientific proof as to why air compressed in a supercharger is hotter then air compressed in a turbocharger, Id love to hear this one.......and Im not being a smart ass, if you know its different please correct me with viable information.



ok her its is :
turbo cahrger and S/C have 2 diffrnt CF;hence 2 diffenebt operating mechanisem, nothing is the same, not even there temp. bothe get way too hot, but then heat is not the olly way to mesure eficiency and power oyt put of a S/c turbo chager. Many thing effect eficency, heat and, Compresible Flow, volumetic eficency…etc

what is CF?
A compressible flow is a situation in which the compressibility of the fluid must be taken into account. In general, this is the case where the Mach number in part or all of the flow approaches or exceeds 1. Under these circumstances, it is usual to neglect viscosity and the Euler equations are used (rather than the Navier-Stokes equations).
For subsonic compressible flows, it is sometimes possible to model the flow by applying a correction factor to the answers derived from incompressible calculations or modelling - for example, the Glauert-Prandtl rule

(ac is compressible lift curve slope, ai is the incompressible lift curve slope, and M is the Mach number).

For many other flows, their nature is qualitatively different to subsonic flows. A flow where the local Mach number reaches or exceeds 1 will usually contain shock waves. A shock is an abrupt change in the velocity, pressure and temperature in a flow; the thickness of a shock scales with the molecular mean free path in the fluid (typically a few micrometers). (turbo has more)

Shocks form because information about conditions downstream of a point of sonic or supersonic flow can not propgate back upstream past the sonic point.

The behaviour of a fluid changes radically as it starts to move above the speed of sound (in that fluid). For example, in subsonic flow, a stream tube in an accelerating flow contracts. But in a supersonic flow, a stream tube in an accelerating flow expands. To interpret this in another way, consider steady flow in a tube that has a sudden expansion: the tube's cross section suddenly widens, so the cross-sectional area increases.

In subsonic flow, the fluid speed drops after the expansion (as expected). In supersonic flow, the fluid speed increases. This sounds like a contradiction, but it isn't: the mass flux is conserved but because supersonic flow allows the density to change, the volume flux is not constant.

volumetric efficiency refers to the efficiency with which the engine can move the charge into and out of the cylinders. More correctly, volumetric efficiency is a ratio (or percentage) of what volume of fuel and air actually enters the cylinder during induction to the actual capacity of the cylinder under static conditions. Therefore, those engines that can create higher induction manifold pressures - above ambient - will have efficiencies greater than 100%. Volumetric efficiencies can be improved in a number of ways, but most notably the size of the valve openings compared to the volume of the cylinder. Engines with higher volumetric efficiency will generally be able to run at higher RPM, and thus power, settings as they will lose less power to moving air in and out of the engine.

There is allot more to measuring efficiency of a charged air , temp is one factor but not the only one.

cool?

Okay, we all know compressing heat makes air hotter. Enthalpies correct? Internal energy of a working fluid. SOOOOOOOOOOO::

Edit: BTW, the screen says "MATH OWNZ J00".

AWDSR20 why are you talking about all those rules for fluids or did you just copy and paste that and is it the same for air? because thats what we r talking about right? and if you did copy and paste it from somewhere they suck at spelling.

remembr..i suck at sp

lol!

btw, i'm taking thurmo dynamics...not don yet, but air obys fluid laws.

Last time I checked the ROlex Lemans series the winning cars were using N/A C5R Chevy motors.....not turbos

Nissan Phanatic and AWDSR gave you the exact physics of lower efficency equaling hotter air. if you want to go back to "its so close to the exhaust" I'll tell you that you can tap a 300 Degree Grill and not get burned. relation = the air is moving so fast it doesnt make contact with the heat long enough to do any damage.

Horray! Turbos use intercoolers too! and intercoolers being equal the higher effeciency = colder air.

Fair Enough... Top fuel dragsters are fastest vehicles ever and use Roots. however what top fuel dragsters do is mostly irrelavant on a street car that isnt spewing 5lbs worth of burning Methonal though its exhaust. you said something along the lines of "for maximum power Id go Roots" which is one of the most misinformed thing I've ever read... you seem to think that every turbo making 350WHP is spooling at 5000RPM and is out of its band a 6000. where as most modern Turbos with 350WHP of flow are spooled to at least half boost at 2500RPM on 2.0 liters. and can hold to 8000


The C5Rs are doing Great... and So is the N/A Ferrari thats been giving it a run for its money. But in the Prototype class Lemans (im not sure about ALMS) the Turbo is King. the Audis are doing 700+ from 3 or so liters the 1.3L Diesel thats going to compete is using a turbo and getting 100+ MPG (or so Ive heard), the Cadilacs were Turbo. You seem to be looking at only the facts you want here too. in every class where turbos are allowed they are either 1) Adopted by everyone 2)Dominate anyone who doesnt have one or 3) be bogged down with so many rules as to make them less competitive


CLIFF NOTES: Look at all the facts - not just the ones you care to see

who cares?
Supercharger Whine is teh gay shit!
Turbo Spool with BOV is the SHIT!

I think monoxide just about summed it up as to why all the JDM Tyte yo people like turbochargers lol........

I tap my turbo all the time and don't get burned.lol

Top fuel dragsters, like their roots blowers, are inefficient. They have an engine built for every run.

in every class where turbos are allowed they are either 1) Adopted by everyone 2)Dominate anyone who doesnt have one or 3) be bogged down with so many rules as to make them less competitive

Words......

Nissan Phanatic

WTF??? :p

Im that kind of guy im JDM Tyte Yo because im hella cool because on my stock steelies they aint got no hubcaps and i got da loudest exhaust i could find for like 100 bux yo.....my exhaust was like 600+ but lets keep that on the d-lowizzle

ok...wiggers are stupid...but lots of ricers are wiggers.

word...

Hey!!!:(

I'm a ricer!!!!

yes, fanat i trust hugh mckinnies lol. i was getting ready to break out his marvelous book to join in the fun, but you pretty much summed it up. And RW through in some more summing up. And one thing i do remember from reading that book 3 times in one week (yes my job is hecka easy and boring as FUCK and 10 hours long) is that roots blowers blow hotter air.

SO, i will just add, that jgtc cars are turbo also(not all, wait or i think they have all went turbo...even the NSX). I think the zanavi 350z is twin turbo VQ 3.0 liter. I think there testing the 3.0 twin to maybe see how well off it is, then there taking the R&D off that and possibly that might be our new skyline engine???? Just my philosophy. I mean why else pick that one right?? The supras dont use a 2jz do they, i forget what they use. Something tells me a v8 iirc. I got more facts jumbled around in my head than i know what to do with. I just need to get them all straight. I read so much shit every day at work that i forget what goes with what. But im learning slowly.

And fanat, i could actually follow that math equation.....(retarded sound) YEAAAAAAA!!!!

FOR EVERYONE, if you really want to learn a thing or two i would highly recommend getting "Turbochargers" by hugh macinnies. Its like 20 bux and will teach more crap and math than you know what to do with. I feel like i can turbo my lawn mower now that iv read that!!!!!!!! lol.

yeah the jgtc supras are v8's almost positive theyre NA. and i think MAYBE i saw something that was supercharged maybe a nsx. or a ferrari. i remember seeing a ferrari in a list of the jgtc cars and the engine was something weird.

They prolly run V8s because they can be run lean as hell and not blow to shit. My dad, being the tuning genius that he is:rolleyes:, had his maro at like 17:1AF(unknowingly) for prolly two years. Ran 10.80s@12x the whole time. Finally dynoed a couple months ago to make 420whp@17:1AF. 388CID. Compression is still good. The clusterfuck at the dyno actually tried advancing timing.... Fucking retarded if you ask me. I told him to jet to hell. was running 82's or something adn I told him to go to like 120's.lol Well he went to 98's and pulled out a 15:1. Went from 420whp to 470whp with a jet change. I told him he could prolly break 500whp with a larger jet.... But what do 18 year olds know???

Large displacement NA engiens can prolly make the same power at leaner AF ratios than Turbocharged engines. Scenes how its not uncommon for NA engiens to run 14.7:1 AF ratios at WOT. Still not good for peak power, but.....

I'll still take my Turbocahrged engine properly tuned please?

it sounds like your dads maro would probably sound mean as fuck but really in my opinion nothing beats the turbo sound. thats what really decides it for me. i love big blocks, small blocks, carb'd v8's FI v8's, high revving all motor honda beasts, supercharged SVT stuff, v10s and v12's but i love turbo 4's the best.

Idk.....

to iN: if that's ur 240sx (by ur logo), dude don't disgrace it. SC'n it with possible 6-8 psi, DON'T EVEN WASTE UR TIME. SINCERE, the USDM version of all KA24DE are NOT(repeat) NOT build to endure heat or force induction (for PETE's sake, this cars have EGR valve on them). Although Japan did a good job screw'n the U.S. version there is an option, (EVERYONE IN THE SAME TIME, SAY: JDM engine swap...ty!) SR20det, rb20det(weights 2much), rb25det, rb26det(t), brew(2rotory:that's trying to be in SEMA Contest, but they done it).
So, if u still like KA24DE engine; unfortunately, that engine will go to hell and back to ever come close to a stock sr20det. ASK ANY ONE!! (=_=)

lol, I knew I was doing something wrong....

Have you ever heard of a little company called Phat KA-T?

BOON FACE (sorry for stealing your expression chuki)

wanna know why the KA is better? Because we take your turbos and make 200whp at the same boost on the same turbo. K?

well yeah but obviously because the KA didnt come with a turbo its nowhere near even close to being able to handle forced induction you are wasting ur time. its not like they have people that make websites all about turboing the KA and selling turbo Kits and parts for the KA.

Wait, they DO? and the KA is pretty much bulletproof? and it has a better flowing head than the SR? and its .4L bigger? and its already in the car? and the crank and rods are already forged?

monooxide, why are you saying S/C whine is gay, and turbo spool it awesome? That sounds kinda ricer ish..idk, i love turbo spool, but a nice s/c right as its starting its whine sounds nice..

I'd rather own a fuel injected small block then anything else


naturally aspirated of course.....

I may not be the smartest person on the block with math and shit, but I know what wins street races from my own experience.....

Torque owns all

more Displacement makes more torque

Displacement OwnZ joo!

seriously if I tuned my LT-1 compartively to your Turbo 4, theoretically, and with enough strength, it would almost make 3 times the power, it would be like having 3 sr20's ahahahah.......

yeah

to iN: if that's ur 240sx (by ur logo), dude don't disgrace it. SC'n it with possible 6-8 psi, DON'T EVEN WASTE UR TIME. SINCERE, the USDM version of all KA24DE are NOT(repeat) NOT build to endure heat or force induction (for PETE's sake, this cars have EGR valve on them). Although Japan did a good job screw'n the U.S. version there is an option, (EVERYONE IN THE SAME TIME, SAY: JDM engine swap...ty!) SR20det, rb20det(weights 2much), rb25det, rb26det(t), brew(2rotory:that's trying to be in SEMA Contest, but they done it).
So, if u still like KA24DE engine; unfortunately, that engine will go to hell and back to ever come close to a stock sr20det. ASK ANY ONE!! (=_=)


WTF? YOU ARE THE DUMBEST PERSON EVER




The Supras use V8s because of the weight distribution. They used to use the 3SGTE but decided the 4.7 V8 would be more reliable with more power downlow although I do belive its got one of the lower power outputs for a 500 class car. Right now the Nissan 350Zs are doing the StallOWNing.

Torque = Horsepower

to much torque and you've got a tow truck that cant get anything done after 40MPH to Much Horsepower and you've got a B16 honda that needs 5.10 gears to get off the line.

I think the 3sgte was the gt300 class motor........

with larger displacement you will ALWAYS 100% make more power while being easier on the motor.... it is a good endurance race setup, the downfalls are the motors are larger and heavier, and consume more fuel.



I can't wait to finally put this Lt-1 into something, im gonna creme myself

625horses waiting to whip some ass LOL, hopefully it goes into an import to screw with people's minds even more.

12's?

11's?

10's?

9's!!!! thats the goal anyhow with a lightweight chassis and big slicks, Will have to break out the sawzall and welder to fit the monster meats

not nessecarily........

by changing cams you can change the powerband to your desired needs. Displacement is the biggest factor I've seen on how the torque curve is placed, you really can't compare a 2 liter to a 6 liter. The 6 liter will have more torque down low no matter what you do to it, and you can still tune it to run high RPM's and good horsepower up there...

Thats why I like the LT-1, a good iron block torque monster that has GREAT top end pull......... you just haven't enjoyed yourself until you take an Impala SS up to 160mph down the south florida interstates...and that baby has GREAT top end....it waistes many a cars on the top end that would beat it in the 1/4.....
