Single Turbo 408 Chevrolet Caprice I had a build thread on here for a while but there wasn't a whole lot of interest. But I figured now that I've gotten it running I might as well post some videos for you guys. The car has a base tune on it right now but once the alky injection kit is installed its going to FROST for tuning.
Here's some specs on the build:

Stage II 75cc L92 heads from WCRCH
EPP cam 232/240 115 LSA
GMPP EFI manifold
90mm Holley TB
83lb High Impedence Injectors
Rest of drivetrain:
TH400 Transmission
2200-2800 Torque Converter
4" aluminum denny's drive shaft
8.5" Auburn limited slip
3.73 gears
Exhaust:
5" to 4" down pipe
4" in/out dynomax bullet race muffler
custom 4" inlet y-pipe to dual 3.5" outlets
Fuel System:
-10AN feed and return
Aeromotive eliminator fuel pump
Aeromotive 100 micron and 10 micron fuel filter
Aeromotive fuel rails
Aeromotive fuel pressure regulator
Aeromotive sump welded into a stock 89 caprice gas tank
Turbo kit:
91mm T6 Air Research Turbo
6.0 truck manifolds
2.5" mid pipes
3" aluminum cold piping
1200 hp A/W intercooler
HKS SSQV BOV
Tial 44mm Wastegate "5.8 psi spring"
I've probably missed a bunch of stuff but if anyone has any other questions please feel free to ask. Hope you enjoy the videos.

I live in Blacksburg but the car is in Mechanicsville near Richmond. If all goes well I should be in installing the methanol this weekend.
As for the 91mm, I've been having a blast. Just rolling into the throttle after the car is already in 3rd gear the it hits 6psi instantly around 3800 rpm. I havent even taken the car over 5500 rpm yet. I really don't think you could go wrong with either a 88 or a 91 to tell you the truth.
