The stage 1 car makes 258 hp on Street Gas, 282 on race gas, after 5600 rpm the power Drops off badly because of the small turbo.......
A stage 2 is Upgraded turbo/850 injectors/pump/a few turbo hoses/tuning on top of stage on....All this will be up on the website soon.

The big thing...is that the car just keeps pullllinnn harddddddd...unlike a stock
or stage 1 STI...which loses power in the higher RPMS

yes they do, and a 24 hp gain using a green over the stock vf39 is depressing, to say the least, even though their dyno reads about 10-15% lower still puts it at about 30hp gain, and I think the stage 2 is an extra 3K on top of stage one

the old thread with Pcowan is still in the vishnu forum, he was beta testing with a GT-30 then mysteriously stopped updating, now their using FP Greens, the blow up is the missing piece of the puzzle I guess.

not trying to flame Mark, Ive seen their stage one on the dyno at ATP and it looked great, and if your happy with it thats the most important part

My car on street gas picked up 35 WHP...which is about 42-45 Crank......the power curve is a TON better...the car picked up 80 hp ....thats right 80 hp between 6000-7000rpm, You need to look a vf39 STI graph, to see where the new turbo shines.

On race fuel the car went from 290 to 342hp...52 whp, about 70 crank...again with the better power curve.

ALL the runs were made in 100+Degree temps...where before on my stage 1 tunning, it was about 65 degrees...I know dynos correct for temp etc...but the car felt alot stronger after it cooled down a bit.

AS is, on the 342 map, the car will hit 11's, maybe even a 11.70's os 11.60's.
How many guys u know install Intercoolers/headers/intakes/pulleys/hoses etc, runin 25#'s of boost, and still won't hit or beat those times???

BTW i made that 290 @ 16#'s of boost
342 @ only 21

well as long as you plan on running race gas 24/7 I guess its all good

like I said, not trying to flame, if 290 is all we can get out of a green on 91 octane than its not yours/vishnus/anyones fault, though I think you would do best to consider a bigger intercooler or even water injection or else your just not using the turbo to its full potential on pump gas, just a thought
