:worthless:

id go with a 57trim for that much power,over a 50trim. and may need a cam and intake manifold to make it easier.

Stock head CAN do it...but easier with cam and such. It's up to the turbo really and how much you push it.

I would stay away from the y8 intake mani. I would do a ported Z6 intake mani+ 70mm tb+ a tb spacer. Those 3 parts will go far in making the power your looking for. Stock cam starts to become limited in the low 400's hp.

get a garrett 57 or 60 trim. its gonna be hard to get 400whp on a stock head. it WONT happen on a 50trim. unless you are going to one of those BS dynos that read high as hell. every 57trim ive seen ont he hub dynos cant reach over 375-380whp. but the powerband is sickness. but online i see it all the time. So i dunno wtf is real what aint. 880cc injectors no less.

59300 zex cam doesnt require springs/retainers. ppl have hit a said 400whp w/o them.

lol naw, word. still seems high to me. any times? also E85 im sure helped alot on that. but then again he could always run higher octane with the 50. i dunno. What gear was that? 78mph? i hit 65 or so in 2nd!!!! peaking at 6k rpms in 3rd is that was gear? wtf.... yeh what times does this run, seems like itd be a good road car/dd.

and i keep 110octane around the house in vp cans 24/7 so running 110 is not a problem if i was to run high boost with it would it be safe to run 22-24 lbs on that 50 trim?

That was because we had a ignition problem at around 6k. It was in third gear. And it ran 13.2 @111 on street tires making 320whp. I should hit 11s on a tire. E85 is the best btw for the price
