~700rwhp on a Dynojet.

But I think the crank will take 800rwhp and hopefully I can demonstrate that with my car.

Stock cranks usualy can take a brutal mid rpm turbo or SC beating. Its the pistons and rods that are the weak points.

I know, those are automatically being swapped for Billet rods and forged pistons, Im just not too enthused about buying a new crank i would love to see pro stock johns crank hold up to 800 foot lbs, go for it bro

Harlan also did 700rwhp on an Eddy current dyno, which is probably more like 750rwhp... Stock crank.

Do I think so? Yes.

I hope to hit the same number with a supercharger.

I have pretty much the same longblock setup as him. That was intentional on my part since I wanted to have the ability to compare similar cars with different FI setups.
