Default Max HP on a P1?

Theres a local guy claiming that he makes 830whp on a P1. If I'm not mistaken a P1 will not make anywhere near this nor will a D1. He would have to step up to a F1 to make that kind of power. I want to do a 40-140 with him and I trap 141. Originally I thought it would be a good race till he blurted a P1 out then I laughed.

This ******* is claiming 813rwhp out of a P1 LS1 that's "bored out to a 427"

His exact post.

it is a 5.7 over to a 7.0L 427ci. Fully forged stroker motor=650hp with a really heavy cam. + P1SC Procharger for ***** and giggles running a 3.85" pully with twin intercoolers.

Oh, ill figure out the limits of the P1 when my project gets going.

Im sure the p1 is not going to blow much past 700, Just my guess. But, ill find out how much I can squeeze out of it.

http://owners.procharger.com/supercharged/202
700+rwhp 5 psi D1SC
D1SC can make 800rwhp in the correct set up with the correct fuel

The Most i have heard of a P1SC making is like 685ish on pump gas so i'm sure with race fuel it would have broke 700

There's been a few guys who've pushed the D1's to max rpm and made in the low 800s, but a P1? That's pushing.

Most of the times you don't hear about guys making that much with a D1 because by the time they decide that 650-750 isn't enough, they sell the D1 and go to a F-series blower and shoot to 1,000 hp target.

I also rember seeing something round 650-680hp a while back from a P1! That does seem kinda high. Hey u never know, It could be possible with a perfectly setup motor and some Q16, but I highly doubt it.

"Trust" made into the low 800's with a D1SC on his 396/4L60 combo. He was over spinning the blower a little bit as well to do this. "KP" also went bottom 9's into the low 140's with his 347/D1SC combo. An old post but did the race ever go down? lol Most I've heard out of the P1's is in the mid to high 600's. Maybe with a REALLY agressive combo into the 700's. The D1SC is quite a bit more potent...I don't think many people try to even push the P1SC that far.

It can be done with a high compression motor but alot easier with a bigger blower.

The car listed above won't make anything near that.
