the turbo system is an old ls1 motorsports kit. which is exactly the same as the tti street kit. going to work on something this winter to replace this piece of ****. tired of pulling it out and getting it welded.

^^^ people went to 500whp fi with those injectors no problem. why would they not work for me ? am i going to be burning that much more fuel because of the lower cr and more boost to achieve the same numbers ?
I did a 8.6 to 1 347 in a m6 vette. On a stingy mustang dyno it made 588 @ 11 psi. 593 ft lbs.
It runs two stock gn turbos....with a zo6 cam, water meth, ls6 intake. It didnt even need the meth and I couldnt get he boost higher at the time. It now runs around at about 17 psi on 91 octane.
BTW its going 100% on it 60's with about 70 psi at idle on the rail. I d go further but its needs 83's or 96's and another pump.

the only aftermarket parts for ignition is the tr6 plugs at 035 gap
you think i can push the .63 turbo to get 500whp ?
if i made 390whp close to 12psi how much more would i have to push it to get 500whp
also i wend down the track on the Wednesday and i would appreciate i you could point out the problem areas for me.

this was done with the stabilizer bar disconnected and quite a big exhaust leak. on factory 245 tires.
