Congratulations to Tim and Bob, and everyone else on our team who was involved in building this monster!
We apologize for not having engine speed or torque numbers. The turbos spooled so fast that the sample period was too short to plot engine speed.
Air/fuel ratio was flat at the same 11.7:1 we run on all our power adder cars. We only did a single pull because we haven't yet figured out how to use the boost controller.
The bottom end is an
INTENSE race block bored .010" oversized with a stock crankshaft and L32 connecting rods, using the 8.0:1 forged pistons we worked with Diamond Racing to develop. The heads are genuine
INTENSE Stage 4 CNC with the same custom Manley valves we ship all over the world. All the fasteners (head studs, main studs and connecting rod bolts are the same ones we spec'd for ARP five years ago. The cam is an off the shelf
INTENSE Stage 4 Turbo grind. The balancer is the Turbo-specific one produced for us by ATI. The turbos were provided by Precision Turbo, and B & R Racing did the beautiful custom turbo headers and piping, etc. The
PCM tune is identical to the tune in our two fastest FWD cars, and needed no tweaking whatsoever for this pull. The injectors are 95-pounders, and they reached 97% duty cycle on this run.
We aren't sure what percentage to use for drivetrain loss in this case. The torque converter stalls between 4,250 and 4,500 RPM so it's eating up a TON of power. Notice that we only reached ~ 100 mph in third gear. That's a good illustration of how much power the converter is absorbing. And we dynoed on huge drag slicks, which also eat power. For these reasons, it's probably quite realistic/conservative to use a drivetrain loss figure of 20%. Using this percentage, 773.2 / 0.80 = 966 crankshaft horsepower. It might actually be more or less, but we think it's safe to say that our cam, heads and tuning are getting the job done.
