to turbo or not to turbo

MoNsTeR`ImPaLa · 11-08-2005, 12:55 PM

ok the way i see it i want another monster but a under cover monster so what im thinking about for my 00 LS L36 is

1.AutoTrans Interceptor - &129.99
AutoTrans Interceptor Electronic Modulator is a permanent adapter plugged into the existing wiring harness with adjustable microprocessors.The AutoTrans Interceptor cleans up the vehicle's signal, while improving shift quality and increasing vehicle performance. Fine tune your transmission!

2.Throttle Position Sensor Enhancer - $84.99:
The Throttle Position Sensor Enhancer maintains maximum horsepower by optimizing the throttle signal sent to the PCM. At about 70% throttle, the TPS Enhancer locks into maximum voltage which assures maximum power enrichment meaning once you hit 70% throttle it tells your car's computer that you're at 100% throttle. This should help initial acceleration by providing more fuel to the engine when you first accelerate hard. This unit also corrects for dead spots or flat spots in the throttle position sensor. Simple 5 second plug-in installation.

and now for the real power

3.Comp Cams Xtreme Energy Hydraulic Roller Camshaft - $294.99

Designed to maximize torque, acceleration and throttle response while providing excellent high RPM horsepower, our Comp Cams Xtreme Energy Hydraulic Roller Camshaft have the Xtreme Energy characteristics with the added technology of CRC (Constant Radius of Curvature) inverted radius of curvature ramps. Comp Cams has enhanced this technique to ensure durability with these most aggressive hydraulic roller cams. If you're looking for added performance from your valvetrain, a Comp Cams Xtreme Energy Hydraulic Roller Camshaft will give you the performance you're looking for. Below are the specs of each cam for your viewing pleasure.
L36 Lobe Specs

* 206 degree/212 degree at .050
* Intake Lift .320 (.512 lift at 1.6:1 rocker ratio)
* Exhaust Lift .325 (.520 lift at 1.6:1 rocker ratio)
* 113 Lobe Separation

4.SLP Full Aluminum Roller Rocker Arms - $539.99

SLP has released their 1.8-ratio roller rockers for 3800-Series V6 engines. These rockers will fit all 3800 Series II engines including Grand Prix, Regal, Monte Carlo, Impala and Camaro/Firebird. As the workhorse of GM's passenger-car powertrain lineup, the 3800 is equipped with a mild camshaft suitable for use in a variety of vehicle applications. Simply increasing the rocker-arm ratio from 1.6 to 1.8 yields valve-lift figures of .464/.459" (stock is .413/.408")-enough to boost output by as much as 10 hp, with no adverse effect on drivability.

Don't be fooled by the unrealistic horsepower claims made by other rocker-arm vendors. SLP's figures were obtained through rigorous testing of street-driven W-Bodies and have proved replicable on SLP's in-house SuperFlow chassis dyno.

These rocker arms are manufactured from high-strength T6 aluminum and feature a roller trunnion and tip that significantly reduce valvetrain friction over the stock steel units. Best of all, no valve-cover modifications or spacers are required for installation.

and now the beast under the hood

5.Cartuning Performance 3.8L Turbo Kit - $2,999.00

Get ready to turbocharge your 3.8L motor and have the power you have been wanting for years. Cartuning Performance has been developing this kit for many months and is proud to release this awesome turbo kit. You will NOT be disappointed with the results once you drive your car for the first time.

Available is a turbo upgrade which gives you a better Precision Turbo PT-61mm trim. This decreases lag time considerably, and changes the maximum hp from 450 to about 690. A VERY nice upgrade indeed.

Installed on the L36 motor (found on Grand Prix GT, Monte Carlos, etc.) Cartuning Performance claims the kit makes 280 at the wheels and over 300 ft/lbs of torque at the wheels, although on the dyno it actually produced 296hp and over 400 ft/lbs at the wheels on a completely stock car with an open down pipe. The standard turbo is suitable for those that want to bolt a turbo kit to a stock car that has no modifications done to it and wants a really fun daily driver. The upgraded Precision Turbo PT-61mm trim is good for the same purpose, but for those that think they want to take it much further in the future, or already have a lot of mods that support more breathing.

6. Cartuning Performance Intercooler Kit - $1,099.00

Get the most out of your Cartuning Performance turbo kit with our Intercooler kit. It is with this Intercooler Core in conjunction with the Cartuning turbo kit that many vehicles have made amazing hp. A completely stock 2004 Grand Prix CompG made over 401whp, with no other modifications done to the car.

and i know i know i better not forget number 7

7.Headers, 1-5/8" Equal-Length 1997-03 Series II 3800
8.Exhaust System, 2000-05 Impala/SS "PowerFlo"
both from SLP

ok well i really cant wait for spring time and the wifey to go on vacation lmao SO FOR A GRAND TOTAL OF $6648.94 USD OR $7646.28 CDN i'll have a rocket oh yeah thats with out install but most of that can be done right here in my shop

so figure it out on paper that should produce huge amounts of power and be close to a high 10 low 11 second car just the turbo and intercooler produce over 401 WHP so im sure with the ignition mods and cam and rockers and lifters exhaust and headers there should be no problem reaching 500-550 WHP

any thoughts

tranny, i doubt it could handle that.

and what info do you have on that ???? i could understand if it was a S/C with all that power on the line but a Turbo is way easier on the trans and with the PCM it would be programmed but im sure if i was going that way the HD trans might be in consideration

bigrod118 · 11-11-2005, 05:05 PM

well you do have apoint, but none the less, more power to the wheels, axles and so on, is still more power thru the tranny. and if I remember correctly the stock axles are good up to about 800HP, which just adding the turbo you wont hit. but I would still look into the HD tranny. and here alink you might want to look at.

and oh yeah, is that topic line supposed to be funny... turbo or no turbo... ok right.. hmmm let me think about that one.... TURBO!

Schister66 · 11-11-2005, 08:58 PM

what are you using for tuning?? You'll never reach that power on the stock little FMU they give you and still expect that engine to last.....but idk, maybe those engines are a little heartier than i think!

Schister66 · 11-11-2005, 09:02 PM

"so figure it out on paper that should produce huge amounts of power and be close to a high 10 low 11 second car just the turbo and intercooler produce over 401 WHP so im sure with the ignition mods and cam and rockers and lifters exhaust and headers there should be no problem reaching 500-550 WHP"

You're going to make that much power w/o any internal mods at all?? Well I hope you post some pics of the fireworks..... BTW, you're getting an NA cam for a turbo car.....two words "valve overlap"

I'm not saying that this whole thing is bad, but i just don't believe some of these bogus claims that some of these companies make....and some of the claims that you've made....not to mention the performance cams won't work unless they're specifically turbo cams.

There are all sorts of companies that show large gains on stock engines...for example, DC did a GSR turbo build. They safely made 334whp on a 1.8 DOHC VTEC engine, but then they upped the boost and dynoed in at 408whp. They could, like most companies, advertise the higher number because their kit CAN produce that, but for how long??

I just dont want you to blow up your Impala is all, no hard feelings, just a little constructive criticism.....

Hope to see some pics of it......

thermal izod · 11-12-2005, 11:53 AM

this just sounds like way more power than the impala was designed for...not knockin' ya, just saying, be careful b/c u could wind up costing yourself a fortune in damaged components

I agree, there is no way a stock 4T65E tranny including the differential and axle shafts will hold up to that amount of horsepower or torque gain.

A stock 4T65E-HD (MN7) on an L67 Impala SS, Regal GS or Grand Prix GTP with moderate mods can barely survive consistent mid 13 second runs.

The mods sound good but on paper only and it will take more money than that to make it consistent and reliable. Just my 2 cents.

i think that a stock impala trying to push those numbers is asking for trouble....i don't think the bottom end will hold, you could blow a hg, you could blow a hole in the piston, fry a ringland, crack a sleeve, and if the bottom end holds (for a little while) you still have to worry about the tranny and the axles. I don't think that the tranny would hold that much power, you'd end up breaking something.

Now it might hold together for a while, but it isn't going to last.

MoNsTeR`ImPaLa · 11-12-2005, 02:43 PM

well for the cam issues if im going to run turbo im not going to use a NA cam there are cams out there for turbo and like bigrod said look into a HD trans <-- knew that and im also looking into the 3.8 stroker that has been mentioned on other forums BR knows what i mean this is all just in the thinking about stages right now and if im going to build it it will be built right the First time liek my truck and my 96 ss both hit huge HP the imp hits 450 WHP the truck who knows we havent found a Transport Dyno in our area yet est TQ around 1200 ftp all im looking for is ideas the whole 6 banger thing is new to me but i have seen a few 3.8's in the 9's so im sure its possible

Schister66 · 11-12-2005, 06:06 PM

JESUS!!! Do you know what a sentence is? You need to use some punctuation. That whole post was just a bunch of words put together in no real apparent fashion. I know its possible to get your Impala to be fast, i'm not doubting that, but w/ the mods you listed, you aren't going to have a fast car....its going to be a dead car. You can do it, but when messing w/ boost, you're going to have to tune it perfectly and build the bottom end to handle the power you're making. A stock Impala has just the run-of-the-mill rods that don't hold a lot more power than the car already has....if you plan to boost, you're going to have to rebuild the bottom end to handle any more than about 400whp...

Oh yes, definitely possible. Here's some more ideas. This turbocharged L67 Grand Prix project car from Stattama/ZZP with 23 psi boost ran 9.728 @ 144.69 mph. 0 - 60 ft = 1.5669. The timeslip is at the bottom of the page.

its definately possible to make your Impala fast, but you're going to have to do more than surface modifications....you're going to have to tear into the engine and the tranny...

Ok now were trying to compose each others sentences. I didn't force you to reply to this post you did so on you're own.. all i was doing was putting some ideas out there basically to see what would work with what. You don't have to be a complete moron about things, like the transmission thing all you had to say was what about the transmission, you might want to go with the beefed up HD trans or even add a torque converter. So if all your going to do is flame FUCK OFF!!!!

Schister66 · 11-13-2005, 01:22 PM

I'm not flaming, you're just getting pissed that your idea isn't bulletproof. I did no flaming....I gave you a little shit about not making any sentences, which made reading that section difficult. If you honestly want some advice, i'll give it to you, but if you want to do this whole turbo system (which i kinda doubt anyway) and blow up your little Impala....go for it.

I was just telling you the reality of the whole thing. If you boost that much on stock Impala rods, you're going to have catastrophic failure. The reason some of the other cars can hold the power is because i'm sure they took the factory SC cars and boosted them.

And by the way, lets be grown ups about this ok?
