Yes, that is a P-1SC, but here is a list of some of the mods.
310 crank, .040 bored pistons, all forged internals w/billet crank, ported and polished heads, 5 angle valve job, custom grind COMP cams, bronze guides, balanced and blueprinted mill, ACCUFAB throttlebody and plenum polished, (which will be removed in a couple of weeks to make room for the P-51). At the time the dyno was pulled, we were running a Reichard oval settup. 75HP shot, with line routed inside fender into discharge tube which has recently been replaced with methanol injection. T-5 transmission (out of Rob Hindman's race car, when he was running a manual). Diablosport dynotuned chip, Ford Racing shorty headers, custom built O/R X-pipe with electric cuttouts, Flowmaster 40s with dumps... to name a few.
The car has been VERY well tuned. You are right, that is a P-1SC, but the pulley is 2 steps down, and devolops around 12psi. At the time of the dyno, the car had 72lbs. injectors, but ran too rich. I have a set of 42 lbs. Ford Racing and MAF going in as soon as it stops raining. I understand your doubts, there are a lot of B.S. artists on forums like this, but believe it or not, this is a 720HP car.
Looks pretty close to mine, and Im at 400 wheel...but on an unbuilt NON pi engine.
