That looks like nitrous torque! Can you say wheelspin? Can you say effortless passing in 6th gear?

This car has stock Eagle Supercar tires. It is pointless. Any more than 1/4 throttle in 1-4th gears and your not going anywhere but to the rev limiter.
I would like to see the graph if possible.

This car has boost issues too. With a little porting to the blower inlet it could make well north of 775 RWHP. We lose about 4.5 psi from 4800-6500.
These numbers are on pump gas with no meth IAT's were around 150 deg @ 6500 rpms and around 120 deg while driving.
Id bet that 112 maggie @ 18psi is hot like the sun...

I'm not sure its the blower inlet, as much as just the lack of pumping efficiency.
We started out with the thing at 23 PSI (with lower compression than it has now) dropped a pulley size, and instantly gained about 20 HP. After tuning for the decreased boost, we netted almost 40 HP. Putting better heads on it, and upping the compression, did nothing for it, but loose more boost.
Sorry for the hijack, just thought I would contribute some of our findings.
Very nice build BTW. Love to see that thing with the bigger pump on it!!
