Just got my turbo back from the shop 7lbs lighter.

Here are the new specs:

Compressor wheel 108mm/81mm (4.270"/3.177") .95ar housing 5" inlet 3.5" outlet
Turbine wheel 95mm/76mm (3.75"/3.0") .96ar housing T6 inlet 5" outlet

The build is stock LQ4 bore & stroke 6.0L w/new forged pistons & rods @ 9.0:1 compression, Comp XER281HR 232/234 112LSA .595"/.598" lift. Ported 317 heads stock chambers + ARP studs and a LS6 intake with 84# injectors.
Turbo mounted in the front with Z06 LS2 manifolds and 2.5" crossover pipes. Stock PCM & HP Tuners. In a 72 Corvette 3000# 4L80E 4-link 12 bolt w/3.08 gears.


What HP do you think I can make w/15lbs boost at the wheels?

370 cubes? I would think through the heavy 4L80E and 12 bolt you'll make ~700ish at 15#s boost unlocked

It will be a 364, the block has less than 10 miles on it so I planed on using Mahle 4.00" standard bore pistons with Eagle 6.100" rods. 700BHP sounds great to me

With a 364 What do you think the spool time and max boost would be with this turbo? Thanks

No opinions on spool time and max boost capability

It will be laggy and max boost will be way higher than you'll want to run.

Thanks Mike, but I think I need to rephrase my question. I'm shopping for a converter for the 4L80E and I was wondering what the boost would be between 2200 and 3000. I was guessing between 5 and 8 but I was hoping someone here would know for sure...
