PT88 Vs S480

[RyanSG]

Hey guys, out grew my 67mm so i'm looking into the big boy turbo's now.

The car is still a "street car" most of the time weekend track car. I'm looking into a PT88 (t4) .96 a/r, or an S480 (T6) with a 1.0 a/r. Anyone have experience with spool time etc on these? I can go both ways since i'm redoing the kit anyway but I'd like to spend the money once and be done with it. I'm looking for around 1100-1200hp at the crank. So I guess the question would be can both turbo's do it? and what would produce the least amount of lag...

Motor:
331 R-block,
Eagle crank and rods,
JE pistons,
9.1:1 comp
Trickflow twisted wedge heads and intake
TH400 with 4K stall (tight)
3.27 gears out back
car weighs around 3350lbs

What you guys think!?

Im not familar with the S460 but with that goal I would look towards a T6 flange it will help, however it is obtainable with a t4 flange. Look at the COMP turbos Turbochargers Comp Turbo - Turbocharger, Rebuilds, Turbo Kits I have a customer that runs their 80mm unit on his 331 and it make over 1000RWHP with ease.
