976 rwhp video on 8-9 psi: http://www.facebook.com/photo.php?v=370427352974162



C5 Corvette LSx 454" CalSpeed build - Twin 70mm custom in shop built rear mount turbos - Allpro LS7 heads, custom CSP turbo camshaft, 4l60e unlocked with PY3200 Yank converter, RPM diff - Car has been 9.6 @ 147 on 700 rwhp already previously

We've now turned up boost to 9 psi and make 976 rwhp on 91 octane /w methanol but ran out of fuel with 80lb injectors with alot of methanol....track times on low boost within current fuel system limits safely (6 psi - 850 rwhp) tomorrow night at Las Vegas dragstrip....

Hopefully a while. RPM 4l60,RPM diff, ECS race driveshaft/torque tube setup currently.

Will be changing to a C6Z06 RPM built 3.42 geared diff shortly as car still has 3.73 and will likely run out of gear at 150-152 now @ 7000rpm, we dont want to spin it any higher for engine longevity.

We shut down the pull way early on the posted 972 rwhp graph (around 6000 rpm) as the car was out of fuel maxed out 80lb injectors. I think itll make 1050 on the same boost just pulling it all the way through 7000rpm.

Car is still strapped to dyno, thinking about putting 96lb injectors in today before we leave with it to the track tonight.

Are you using the stock STS cold side piping or have you done something custom?....

Really good power anyway!

Nice, I'm in for pics, also did yall turn up the boost while it was still on the dyno, or did you decide not to mess with changing injectors

How did it do at the track?

Complete custom turbo in house build, we consider this a MUCH improved setup, dual 2.5" feed cold piping from rear which I havent seen on others. Zero ground clearance issues.


Took car to vegas to attempt to get down track last night which we just left after finding out zero track prep (no vht spray before/during, completely dry track), no water /burnout box etc since it was a "street car" night .


Did throw it on chassis dyno on lower boost 6 psi dynojet while in vegas today: made 846 rwhp

pretty sure I saw this car at the track before it was boosted , if I remember correctly it destroyed the trans in the line

Really be intrested in seeing the route you took for the pipe work. LMR did oval piping on RC / thier vette. worked pretty well and gave no clearence issues. Looks l;ike you mount the turbos in the normal STS location though.
