I did not find what I am looking for searching around; so will a supercharger work on the LS1 engine on my 02 TA? Will it fit right? If so who makes the best one out there, the cost, and what modifications would need to be done if I can go this route? I really don't want to go turbo or twin turbo and deal with the intercoolers too.
If I can't supercharge, then I will just have my engine built by a reputable shop like Lingfelter.

Alright it looks like the Procharger from Brutespeed is one option. I already have shorty headers and a Magnaflow exhaust. I don't need crazy whp, but 400+ will be nice. I will be talking to Bob later this week to find out the direction I should go.

Last I remember the P1, D1, and F1 procharger kits have intercoolers. I'm no expert about FI but I wouldn't procharge a block with stock internals. But that's just me. You can get 400 rwhp from bolt on's and a H/C/I... easily.

NoJoy

You are right the procharger has intercoolers too. When you say change out the stock internals are you talking about the pistons? Are they forged? Also what is H/C/I? Thx.

Heads Cam Intake, you could hit your 400 mark with a good cam and tune. No need to force air, and if you want more nitrous is way cheaper

H/C/I setup will be cheaper then a procharged setup. I would go forged internals for a FI setup (pistions, rods, etc..).

NoJoy

Thks guys for the feedback. ProCharger will be $6000.00 plus labor. Lingfelter stage I is $8900.00 everything included. I am just looking at the best options. I could certainly start with the Heads, Cam and Intake and go from there. I already have headers, K&N airfilter and a Magnaflow exhaust. I am sure my car is right around 290whp now, so if I can get up 400whp-that will be enough for me (for now )
My goal is not how quick this car can be-but top speed potential.

290 rwhp is the low end of the spectrum for a bone stock 4th gen. I would say you're in the 325 range.

Forging the motor would be nice but not necessary if your keeping it around 7-8psi. Guys push 550-600rwhp on the stock bottom end all the time. Getting a good tuner is even more important with FI.

NoJoy

I thought the WS6 TA was at 325hp at the crank. So the WHP would be lower than that. I need to put the car on a Dyno and see what my car is putting out before tuning it, to get a baseline figure.
Anyways that's pretty cool that guys are doing 500 WHP on a stock engine (and transmission) Forged internals would eventually be the smart way to go-but of course cost more $$$ up front. Great info so far-thx guys!

The cars were underrated. They typically put down 290-315whp stock

if you buy new , get a d1 , and get the 8 rib setup from the start .

But if you want 400 , go with cam , fast 92, longtubes , 85mm maf , slp underdrive pulley , smooth bellows , and some gears .

NoJoy

I see your car is procharged. Is this the set up you have? How do you like it so far?

let me add it up and get sad.

2500 for the p1sc-1 98-02 fbody 6 rib kit used.
Then a tune 500 , then a tune from a place that knew what they were doing 550

then i just upgraded to a sdce 8 rib setup so that was about 1200 in stuff , then im adding meth and bc of pulleying down and adding meth i need a partial tune so between meth install , and meth kit and retune thats 1100 bucks .

so its not cheap .

But if you buy new go with a d1 the option is real cheap , but to upgrade a p1 its like 1200 bucks .

Someone has a 8 rib kit for 4000 right now , with the 430 dollar ati damper you need.

NoJoy

Don't feel too sad. I spent $14,000 in engine, suspension and other "upgrades" on my STi in three years. If my car wasn't for sale; forged pistons and a new turbo would cost me another $7,000 parts and labor
Anyway good advice! Now for a newbie question. What does "rib" mean. And what is the difference between 6 rib and 8 rib? Thx!

Your ax belt is 4 ribs. Your accessories are 6 rib. Flip the belt over or look at the underside of it. It has ribs. 8 ribs are better as the belt is wider which gives more grip. The 6 rib is good to start with if you don't haw a lot of money but if you ever wanna to make more than about 4-6 lbs you need 8 ribs.

NoJoy

Gotcha. 8 rib it will be then!
Ok now for another fun question. Your car looks to have serious hp. What is preventing a top speed of say 190mph or even 200mph. Is it the gearing of the car or combo gearing and hp. I want to see how fast this car can go, and I think procharging is a great idea to get there.

well your intake temps will get wicked hot after a long run , you will need a huge intercooler. water to air is a good setup for that . You more than likely don't want to have to go into 6th gear, so you need to get your setup geared right . You will need a lot of hp to get up to 190 or 200 . Aero will need work . Go buy a c6z if you wanna go that fast . It will be so much easier and safer . More expensive yes.

NoJoy

I was thinking a simuliar thing. Then engine will get very hot going over 170mph, especially having to wait to see what the top speed would be when all the suspension and engine mods are done. Salt flats is a goal of mine in the near future. There is a breaking piont of course on how much money I want to spend and diminishing returns. How fast do you think your car will go with your current set up?

Stock your car should be able to hit 165....it may take you a little while to get there, but there are a ton of video's of bone stock LS1's doing just that.... With Head/Cam/Intake/Gears...... 185-190 is doable, but without the proper aero it will get nasty pretty quick, 190-200 requires even more hp, somone had a calculator on here, and then because of the aero WALL you hit at 200 mph, each addtional hp is something cray like 40 hp or 50 hp per mph ...not sure i may just be making numbers up here, but I think you can find similar threads with a search with people who explain it better then my sorry ***.
