twin turbo question!

l wonder,

if you put atwin turbo and a catback exhaust, headers on a bone stock ws6 LS1 trans am, how much HP would it push and torque? and what would be track times and speeds??



thanks...

erdal.

Depends on PSI. If it was twin turbo, technically you wouldnt have cats (maybe you would if you wanted) and they woulf no longer be headers but rather shorter manifolds.

I still say twins are a waste.

Probably around 500 RWHP...maybe a little more.
The question is a little too broad to answer accurately.
Track times are all dependant on driver and the ability of the car to get traction.

ok what would you do to make a bone stock LS1 750wrhp??

l really do not want a lonngg list of mods?? single turbo ?

u tell me Curtis.. l am just curious..

First off...LS2 block. The bigger bore helps. Forged internals. Single turbo. GREAT tune!

There was a guy local to me that had 670 RWHP outta of the stock LS1. Stock heads, stock cam, all stock internals. 13 PSI of boost from a single turbo. Hard part is keeping the motor in one piece with that kinda power. That is where the tune comes in. It has to be PERFECT!

There are all kinds of ways to get to that HP number. None are cheap.

Damn straight!! Just put a Mustang 5.0 crate engine (345hp) in it and you'll be happy! If not then add to that or just by a Mustang. Come over to the good side of the force Luke....Sorry, I just watched Star Wars again.

Curtis...

maybe u guys will laugh at me but l am dead serious, l will make my trans am between 750 wrhp to 1000 wrhp. (but that is not gonna happen right away)

first thing, l will get that wheels that u got, turqos or whatever and 335/30/17 tires.

a big cam
a big single turbo

(headers and a good cat back)

a good intake

compelete tune up



how many horsepower would l push with those mods that l listed above??

(l started to save some:D )

dude,

ls1 engine pushes 340 hp too (almost) l really do not need a mustang,

but thanks anyway..:)

Erdal...the stock LS1 isn't good for that amount of power. It starts getting touchy around 550 RWHP.

You are going to need to invest $25K+ to get that kinda power.
And that is to just get the power. Not to make the car support it.

so you mean,.

that l need another engine??

what do you recommend? which engine could handle 750 rwhp?? and how much would an engine cost me?

thanks..

Erdal

I would recommend at LEAST a new motor.
For that much power...iron block. Completely forged internals. More cubes helps.
If I were to toss a turbo system on mine....I would be looking for roughly 750 RWHP. I would have to get new heads to drop the compression so I can safely run 13-14 PSI. I would have to get new turbo exhaust manifolds.

Like I said man...to find that much HP you need a TON of cash.
Remember though...bigger isn't always better when it comes to a cam. When running with boost you don't want a bunch of overlap in a cam. This will most likely keep your cam fairly mild. Don't want that boost wasted with overlap.

My shortblock (http://www.arbybean.com/ar/images/402a-2.JPG) cost $3725. This doesn't have heads, cam, gaskets, anything. It is the rotating assembly. Nothing else.
What you see in that pic is what I got for $3725. If you are looking for 800+ HP you might end up spending more on stronger internals.

So technically speaking the LT1 is better off when aiming for high power...Because its iron right?...and all you have to do is reinforce the internals.
Erdal I mean not to discourage you but to get that amount HP out these and any car you have to be willing to spend ALOT of cash and 25k sounds about right.
I realize that with the business im growing soon i will be able to afford my favorite car..."Corvette Z06"...ill take it over any super car. but i would still like to keep my Formula and get it up to 525-575 rwhp. What do you think is the quickest way there Curtis... Cam, and nitrous? I already have headers and soon i will upgrade my intake.

Nitrous works as long as you don't mind power that isn't always there.
Stuff works great, but has to be turned on.

The iron block is more sturdy. Doesn't matter until you start making HUGE numbers though. Aluminum is strong as well, and can easily be good through 600-700 RWHP with NO problems at all. Any more than that could start pushing the limits.

Just get the 572 crate engine. I think its less than 25K. But good luck trying to stuff it under the hood of an f-body.

If you want 600+RWHP, just do what I am doing/did

(well...other then buying a new block if your current block is in good shape)....
Diamond Forged pistons
Eagle Forged rods
*remember $$$ for the machine shop hone/etc*
Cam setup for turbo(ie..mine 208/230 .545/.579 121LSA/valvesprings/lifters/pushrods/etc.

Stage 2 heads
all gaskets/etc
60# injectors/fuel rails
new feed/return fuel lines
dual 225lph walbro intank fuel pumps
new fuel regulator
computer tune.

I am running a T70 turbo with an intercooler and alky-water injection(for boost above 9# or if outside air temps are 85*+)

After that, you still need to beef up tranny issues and definately rearend issues(12 bolt/9inch). Then what good is all that power if you can't put it to the ground, so now you're looking at suspension. First you have to figure out if you want a drag race setup(suspension) or daily driven/all around. I went daily/all around. Its much easier for me to put on a set of DRs/Slicks at the drag strip then it would be for a drag suspension to go do what they need to do to go across country or on an autocross course.

What I'm trying to get at is that there is a whole lot more then just I want to make over 'xxx'rwhp. See what I'm saying? Oh...I forgot roll cage too :wink:
