2000 grand prix GTP on the road to 400 hp

[GRIZZLY505]

i have a stock gtp and i want to at least push about close to 400 hp and i was thinking about getting new pulleys for the supercharger headers and better exhaust flow, air intake and maybe a chip any other suggestions?

[REDCRAPGP]

Better rethink your goal... Making 400hp on a SC is going to be hard better look at Turbos and E85

And then factor in $3k* your going to spend on a trans to hold that power.

I'd just buy a 400HP sticker, slap it on my car and call it a day! =D

1 pulley for the supercharger, headers, intake, and a proper tune would probably have you close to 220whp.

Your car would be lucky to make 190whp SAE corrected on a dynojet... bro.

Buy all the chips for it.

I'd suggest Lays.

I like jalapeno kettle chips myself.

nobody ever asks this but are looking for 400 Crank hp or 400whp? big difference between the two. 400chp is easier to get then 400whp.

Why 400hp??

To really make that power with a S/C you're going to need a bigger more efficient setup, or absolutely max out a Gen V. Think more along the lines of excessively ported heads, matched LIM, headers and betterflowing cat-back, tiny ass pulley, E85, Intercooler, nasty cam setup to max out those heads, firehose fuel injectors, big ass maf and one hell of a tune.

And a 3K transmission.

Then you might be 400WHP.

Or slap a turbo setup on it and be done with it.

Idk... I made ~450hp at the crank with a smaller roots blower.
And I did it on stock heads without an intercooler

What was the setup, and what was the dyno corrected to?

[SnowFlake]

What was the setup, and what was the dyno corrected to?

TVS1320 with a 2.8 pulley (saw 12psi on the dyno with an open downpipe, should have run a 2.6 pulley to see ~14-15psi where the TVS likes to run), XP cam, 105# springs, SSAC headers, N* TB, 60# injectors, e60 ethanol, walbro255 pump, and I tuned it.
372whp corrected
374whp uncorrected (actual reading)

SWEET. Its only an hour drive to get E85!

xpz cam, zzp/intense stage 3 heads, gen v on a 2.6, e85, headers, 3" exhaust, 75mm tb, with a jesus christ tune, and you will be pretty close
