i have been looking at making my 408lsx a 427lsx. would this 91mm t4 be the trick? i have a 88mm mid-fra. now and i am looing at making 1000rwhp, but i have been told that it cant be done with the 88mm???? it made 821 at 18psi on stock 317s, and i just got some new trickflow 235, do you think i can make 1000rwhp on the 408 with the 88mm? or go the the 91. orrr. do i have to go to a t-6?
BTW- its in a 5700lbs denali

biggest "I" would go would be 370ish cubes with a T4.

Well I plan on staying stock cubed LS2(or as close as I can) and I only want to make 1000whp on the dyno(as bragging rights) and I plan on running the car at 650-850 on the street/track

any clue on spool? would it be a decent choice or would there be a better option?
My car with an s374 ran 10.7@133 and some 134 traps this past weekend.. THat was with 10.9 psi and a 1.8 60ft...... damn 255 radials didnt get it done.
Shift points anywhere from 7500 to 7900 rpm.....
What is the downpipe out let size?

it made 995 with worse heads and lower compression when 6 speed w/ 1psi less boost and a little less timing than now.
that exact same set up made 893 rwhp unlocked 4l80
i figure with the above changes it picked up 100rw. with the 91 i am looking for another 100 on top of that.
i still would like an inlet cover for the 91 cut down to 4" od... certainly you guys have the capability??

I have talked to one of the guys at forced inductions before... I am on the waiting list for the new gtx 80mm coming out... But a 91 would be fun and different im sure....
Maybe make for some good texas mile runs, and some rediculous trapspeed 1/4mile passes.
And keep my current unit, or maybe the gtx45 for the street and some grudgeracing.
