So, we hit the rollers today and holy crap, this things mean.
Justin @ VMP sent me his mail order tune and on the stock Roush pulley it made a high of 592 RWHP and 472 RWTQ at only 8 PSI
We swapped pulleys to the 79mm and made another pull. Had tp get out of it as we maxed out the pumps and started to go lean, but it made just shy of 628 RWHP and 501 RWTQ.
I'm sorry, but that's WAY more then I expected and I'm thrilled.
We did an intake test on a FRPP/Whipple car a month back and it made 522 RWHP on the stock pulley 7.5-8 PSI and that's what I was expecting.
My car has long tubes and high flow cats, but still didn't think it would make these numbers. Oh, and I ran it 3 times with the stock pulley, 578, 581 and 592.
