408ci Twin 67mm preliminary dyno results...
We made some pulls with the 408ci twin 67mm turbo build we just completed.
Engine is our extreme 408 with AFR 225 heads, LS6 intake manifold, accufab 78mm throttle body, BS3 engine management, 96lb/hr injectors, twin bosch fuel pumps.
It made 988rwhp @15psi boost, 17 deg total timing. The dyno was having trouble reading engine RPM so no torque, but the BS3 datalog showed 7,500rpm on this pull. Cam is a 230/230 @.050 113lsa hydraulic roller on Comp lobes.
It is a 6-speed car running through a dual 3in exhaust exiting at the bumper.
We managed to keep the stock radiator and fans so it is running a consistent 180deg coolant temp. We'll probably turn it up a few more PSI when we get some better tires on the car.
Details of the build and dyno sheet-

Holy crap.
Welp, you've got my attention.
Whens this kit ready for production/sale? EDIT: just read the other thread...
I can't believe you fit all that, PLUS a 9" in the back of that car. Amazing job..
What's the ride height of that car look like? Was there much room between the fabbed gas tank and the 9"?
