Quick whp-related question about 08+ STIs

RideZX-6R · 12-26-2009, 03:39 AM

I'm looking into getting one as it looks like my Corvette should sell shortly.
I took at look in the dyno section threads and the sticky at the top and it seems like a lot of stuff there was upgraded turbo plots.
I'd like to know (on average), what a tuned 08+ STI (probably buying a new one) put down with intake, 3in dp, 3in test pipe, and 3in cat-back with a tune? Maybe with headers and up-pipe too.
That's all I'd plan on doing (engine wise), I'd like to get as close to 350whp out of the car on 93 octane as possible with the stock turbo and without meth/water injection. Is that feasible?
Lastly if this should be in the "newbie" section feel free to move it but I looked where I should have looked and found a lot of big turbo dyno plots and not much for stock turbo cars
Thanks

So you're saying 350awhp would be close but it'd be more like 325-340?
Or??

closer to 300 or 310whp.

RideZX-6R · 12-26-2009, 02:58 PM

So is 350whp on the stock turbo even possible?
Just wondering

It depends on the dyno, the tuner, and how long you want the engine to last before it blows up. In the long run, upgrading the turbo will be a more cost effective way to hit 350whp.

20G, fuel pump, injectors, DP and a tune.....
When I had my 06 I got 330whp with a TBE, top mount, meth and a very good tune.
