blue print for 700-800hp in ls3 long term

[LSxJunkie]

1. Have you ever ridden in an 800hp car?

2. Have you ever driven an 800hp car?

3. Do you have any realistic goals for the car, other than "I want to be able to say I have an 800hp car?"

If you don't want turbos, you're going to have to run a centrifugal supercharger. Positive displacement blowers won't cut it. Look at Paxtons or Prochargers. Decent amount of boost. And meth. With your goals, you're going to want to run meth. You're going to need a completely forged bottom end, one hell of a clutch, Rockland Standard's Tranzilla, a new driveshaft, one hell of a rear, new stubs and axles. You will replace every single drivetrain component to get that 800 to the ground safely. Be prepared to spend at least the value of the car.

Oh, and if you want to go drag racing, you're going to need to swap out the rear Brembos to fit a decent tire, like a 15 or a 16 with at least a drag radial, if not a full slick, and you're going to have to throw a cage in the car, because I guarantee that car is going to be running under 11.5. You'll have to tear apart the interior, cut it up, and weld in the bars.

If you want to go road racing, there is absolutely no reason to have 800hp.

If it's going to be a street car.....good luck. I hope you know how to keep a car straight when it blows the tires off at 110 as you get into boost.

[airtime]

my wife has a 99 mits 3000gt vr-4. factory twin turbos set to 320 hp. v-6 motor, 24 valve


people are putting larger turbo's on them and putting out over 1000 hp to the ground. these are stock motors, cams. these cars are at least 10 years old have have over 100k miles on the engines. very seldom do you hear of a motor failure.

why is it that these motors can handle the power where the chevy cain't? even with forged internals many people say 800 hp is it. is it just a poor engine block design? i'm a chevy/camaro man just curious?

Question #1 YES
Question #2 YES
Question #3 My goals are always realistic.

I must say that I agree with all the points. Anything more than 600 on the street is overkill. I know people with 800 horsepower cars that can't beat a 500 Horsepower car.

It's a lot different to make 1000 horspower on the chassis dyno and go rounds in a heads up class.

Several years ago I was at a test and tune. There was a high horsepower "Shop car" there. I think it was a DSM. I was going round and round and made about 5 passes in 6 hours. They pulled the shop car out to run my mid nine second car. It was the only pass they would make with the car all day.
I was amused that he suddenly was in the water box when I was heading up to make my last run.
Since it was their event I wasn't going to complain LOL.
We line up and when the tree came down I had a .063 light with a 1.38 60" foot. He was still on the line trying to build boost.
I was 50 foot from the finish line when he finally got past me. He ran a low 9 second run to my 9.8X. It was funny how they talk about all that power but in the real world it almost got beat by a car that makes 580 at the wheels.

Horepower doesn't always mean it's fast.

i wasn't really talking about racing in general just about the motors. the 3000 gt cars weigh well over 4200 lbs. so it's a pig right off the bat and not suited for any type of serious racing. but their are several guys running stock suspension, transmission, rear ends and motors going into the low 10's and i think a couple of these are into the high 9's. these are street driven cars with full factory interiors, a/c etc... i don't think you can compare them to your 9 second race car.

i was just mainly talking about the motor and how well they hold up to high horse power and torgue. these are street driven motors with high mileage.

They do not weigh anywhere NEAR 4200 lbs. Those pigs weigh in the 3700-3800 lbs range.

[airtime]

you forgot about my fat butt and my fat friends. lol

you are right 3700 to 3800 lbs. been awhile since i looked at them but most people weight them with a driver. so 4000 lbs is the driving weight, but still not 4200 lbs.

what lets go in the chevy motors when the power goes up? taking into account no knock or tuning issues. just curious, i'm an old iron guy and not real familiar with the new motors. my camaro has a factory 300 hp 327 out of a 1966 chevelle. so as u can see i'm behind a few decades in my chevy's

I have hit the 556RWHP mark all motor on a 408 stroker in my 99 Z28. I figure that's a pretty high number at the crank, but I won't guess at numbers. I promise it is over 600HP at the crank, though.

You'll need FI and a built engine. I don't think a built 454 LSX can hit 800BHP naturally aspirated. Turbo kits will be your friend hitting 800BHP.

why cant it hit 800 n/a? GM does it with less displacement in their nascar motors.... lol

its not the block design. its compression ratio. your wife's 3000gt comes with a cr of 8.0:1 where as the LS motors are already above 10:1 cr in most applications which is not good for boosted apps. if you built an LS motor with 8:1 cr and boosted it properly, it would lay the hammer down....

side note... its already been done.... lsx 454 TT pushing 2500hp

that one on race gas.

theres another vid floating around of one on pump gas.

ive seen ~340hp cars beat 500+ hp cars numerous times.

Of course you have Robin! I would have hoped so anyway.

Realistically I am thinking 600 will probably be my limit... 426 will be just fine for a while even, until after I get my stripes painted... if I got that route. Depending on the sound of the exhaust that well be my first performance upgrade.

But I'm with you, over 600 is a waste on the road...

+1
I also think 600 rwhp is pretty much the limit for a street car.

[JC Turbo]

have you ever even had a car with 700 hp ?

for me, i want Full exhaust,.. and heads/cam 500-550 will rock on the LS3 and be easy to achieve !! CANT WAIT

I love when the smart people all come out of the woodwork at once.

Case in point? Supras. 11.8@156mph w/ a 2.3 60'. Wanna race from a roll?

(And yes, I know that there are a metric shit ton of Supras out there running single digits. However, there are even more high hp street cars that are absolutely useless for anything but roll racing.)

Bench build with me....R07 hooked up to a T56 in a 69' Dynacorn Camaro with a Lateral Dynamics 3-link, a DSE front subframe, and some 18" Chevy Rally replicas.....I'm thinking 11.5" in the back with 315s. Toss it all together for the price of a ZR1.

Ohhhhhh yeaaaaaaahhhh.

You're going to need much more than 315's out back. I run 315's on the Cobra and it's borderline and it's only pushing 450rwhp.

Hahahaha. I can imagine. I just threw that up there to get around the whole "$1100 a wheel, $450 a tire" ridiculousness.

Oh, and how do you think us GTO folks feel? We can make all sorts of power and without notching the control arm and cutting the fender lips completely off, we can get away with 285s at the widest.
