Whats the fastest

[Legionofone]

ok well me and my dad have been having a argument...

what is the fastest tunner engine in the world

i claimed that the skyline/supra's inline 6 can be the fastest and morst powerful (1300 HP)

he thinks that a V-8 can have more power, though i havent ever seen one with 1300

i might be a total dumass here but whatever what do yall have for imput

Yup.

It depends on what sence your talking about and differnt factors. Street legal stock production cars, modified street legal, not street legal, drag racing, circuit racing.

Turn on your TV and watch NHRA drag racing. All things being equal the one with the most cubic inches wins. If you do all the things to a big block V8 that you do to the Supra 6, well you get the idea.

Top Fuel have over 8000hp to put things in perspective. Halfway down the track, since the fuel is burning so quick and hot, they melt the spark plugs and it essentially diesels the rest of the track.

Cool!
I did not know that. Somehow I don't get to work on any top fuelers under the ole shade tree..

u cant do all the things u can do to a skyline or supra inline 6 to a big block hemi (the most popular high power V-8 right now) the compression on the hemi is to high to put the high shot of nos and REALY high turbo boost... if u did that to a hemi u would drive maby 2 miles hit the nos and that pistons gunna fly strait out bottom... and it definately wouldent be perdy...

Sure you can. Engines are engines. They are big pieces of metal with pistons and cranks and cams. You can put lower compression pistons in a Hemi or use thicker head gaskets to lower compression. The shortblock itself (lower rotating assembly) has almost nothing to do with power output. Power is in the heads, cam, and the design behind the whole thing. A 3.0 liter Skyline engine is no better than a 3.0 liter BMW inline 6, or for that matter a 1973 AMC inline six. The secret is in flow, velocity, and cam technology.

Certain engines present inherent weak points. For instance, I wouldn't build a race engine from a 403 olds since it has a weaker lower end. I wouldn't build a reliable daily driver from a chevy 4-cylinder since they last about as long as one of Brittany Spear's engagements.

If you're going to add nitrous or a turbo to any engine, you tune it the same way; proper ignition timing, compression, and cam events. No brand is better than any other.

If you want to get literal on the subject, the small block chevy -- although cliche' -- is the easiest to modify, turbo, blow, nitrous, cam, and modify. Its the easiest because it IS cliche'. Everybody has one and the aftermarket support is easily a thousand-fold what you can find for any import.

Displacement is displacement. Given the same flow and velocity on the same cam timing events, they'll all do the same.

The other thing that you have to consider is, how long will that skyline 6 last at 1300 hp?

Any engine is a "tuner" engine, its just that the word "tuner" was coined by the sport/import scene. We American Iron folks have been making "tuner" engines since 1915.

Here's a little interesting tidbit. In 1907, "tuners" had engines that make more HP than the sport import "tuners" make today. Hurts doesn't it.

yes, top fuel dragsers are V8, but think this whats in the 2000ft-lbs semitrucks we see every day? 90% of them are inline 6s. in my mind the most efficent to least engine designs - H.O., I, V, W. a H.O. engine the downward force of the piston is moving another pistion up. an inline engine the downward force is absorbed by the main caps. in a V engine, the downward force is also absorbed by the main caps, but in two different directions, fighting each other. a W engine is the same as a V, but the force is in four directions, not two.

i would think a inline 6 would beat a V6, and a inline 8 would beat a V8. but i don't know about a inline 6 vs a V8, its about equal to me.

[Legionofone]

but they couldent go as fast as us HP means alot its power to weight ratios and how well u transfer the power from the engine to the wheels... depending on the cars even now can loose 15-20% of the power as it transfers to the wheels think of back when they dident have the tech we have now... 30-40% loss... maby more... so ya i mean the basics of a engine hasent changed in ages... so they can drop just as much power into cars as now... just cant get it to the wheels as effeciently... o ya and curtis can ya get me some more info on those cars i would be interested to see a model T with 1300 horses i ur probably meaning 300-400 HP though its a big jump though... the first V-8s made i think 90 HP or something

[curtis73]

First of all, no early engines made 1300 HP, that wasn't my intention to imply. But several of the early engines were modified to make well over 300, which is far more than 99.9% of today's "tuners" make.

HP means alot its power to weight ratios

HP actually means very little. Torque means everything; how much, when its made in the RPM range, the shape of the curve... HP is torque over time, so without torque, we can't have HP. I don't care if a 2.0 liter Honda makes 3000 hp. If it doesn't make torque in the right places, its a worthless piece of junk.... which is my problem with the automotive market right now. Manufacturers target young buyers with this "horsepower" word, and it means very little. In acceleration, HP has relevance since its a good mathematical illustration of torque vs. weight, but the force you feel between your ass and the seat is torque and nothing else.

I would think a inline 6 would beat a V6, and a inline 8 would beat a V8

Well, it all boils down to a million factors. In general, a V6 of equal parameters would probably make more HP and less torque than an I6. An I6 has 7 main bearings, but a V6 has 4. Therefore, the V6 has about 44% less main bearing friction than the I6. The I6 will have (with the exception of race-style individual throttle-per-cylinder intakes) trouble equally distributing air to each cylinder compared to the V6. Sierra, although your theory has logical value with the main bearing thrusts, the fact is that the journals are riding on oil and the oil takes the forces. It transfers the force to the iron in the mains and since the whole thing is riding on a circle, it doesn't matter which direction the pulses force the crank, provided they effectively apply it at the right time.

Legionofone, if you look over your posts, it appears as though you've already formulated your opinion long before you asked the question. You asked us our opinion saying you knew nothing, now you're defending your viewpoint. The fact is, displacement, volumetric efficiency, and friction are the main factors in power production; not import vs. domestic, not Nissan vs. Chevy, not old vs. new. I could make a 3000 hp Dodge slant-6, but its not practical with the flow from the available heads, the strength of the block, and the availability of suitable pistons and rods.

Stop telling us the right answer and just read what the knowledgeable people here have to say. You might learn something. There is respect in all makes, models, and engines. They all suit different purposes and your skyline 6 is not the pinnacle of engineering, so stop defending it as such.

.... And by the way, I guarantee that if you put a 2000-ft-lb engine in any street car, it would destroy any high-hp skyline you could dream of.

Ahh, my neighbor has a pro stock 73 and 69 camaro. 540 merlin block bored out to a 560. I don't know the compression hes running, but I know its high, (12.5:1 sounds familiar). On top of this motor hes running a wieand 8-71 blower pumping in 23psi of boost. On top of that hes running a 500 shot of nitrous. On the dyno, he pumped out 2600 some horse power without the shot....

As curtis said, an engines an engine. It all depends on how you build it or what its weak points are. You say you would blow a rod out of a stock hemi with high boost and a shot of nitrous. I bet you would do the EXACT same thing to any honda, toyota, or any other manufacturers motor. High boost+Big shot of Nitrous= always a dangerous combination.

[Legionofone]

2600 HP would of eaten the dyno for breakfast... that thing could never handel that much... hell the skyline with 1300 jump off the damned thing and nearly breaks it... with umm... lets see 3 ties in the back 2 on the side and umm 3 people on the car... he must of had like 6 in the back and a bus ontop of that car...

and torque doesent mean everything... there used to be a class of motorcycling that had to be tow started because they were so highly geared that they dident have the torque to start moving and they broke i cant remember eactly like 130-150 mph so no u dont need torque to do anything its the power of the engine torque and HP are 2 different lines on a dyno graph... and the skyline put out 857.5 HP on the day it almost killed the dyno...

[Evil Result]

Well i look at HP as how long an engine applies its torque...

Although 2000ft/lbs of torque is great how big and heavy is the engine how high is the redline 4000-6000... and how are you gonna manage all that torque? Big heavy Transmission? all this big heavy stuff keeps adding to the drive train power loss...but how much i'm not shure.

with high HP low torque motors...i have the same ability to multiply the torque to the wheels just like the V8 but i can applie that multiplied torque over a longer period of time becase of the high redline so that means i'll still be pulling longer in 1st gear when with the large V8 you need to shift to 2nd gear droping the torque to the wheels.

thats why HP seems to be the final answer i need..if the transmission is geared correctly. even though both engine may be hugely different in the way they applie there torque what matter is how long they do it...if they both have the same HP and the drive trains are matched accordingly they should(in theory) both preform the same.

[Legionofone]

haha oops i mean 857.5 ft lbs of torque hahaha dumass me

[TheSilentChamber]

Wow... some of the (mainly one or two) people in this thread amaze me. Ask questions then automaticaly turns around to defend their point of view. Highest hp cars arnt allways going to be the fastest cars, supra and skyline are not the fastest cars in the world- you've been watching too many movies. A 2600hp camaro is hard to believe, but I cant prove you wrong so theres no need for me to argue about it. The torque and hp of a motor does not determine its redline, nor does the weight of the drive train. It does have to do alot with engine design, a motor isnt allways the same as the next, otherwise hp and torque would strictly be based on displacment. As for the fastest motor, do like suggested above and look at NHRA records, you'll find it, and it will be a v8.
