My car is ported stock blower/cam and made 780whp with Meth. I have since deleted the Meth and now tuned without it. No clue where I’m at but I’d guess 710-720whp
Yes I’m one of them.

I doubt your 710-720rwhp on stock fuel system btw.

You don’t need e85 or 93 with meth.

This is on 93 w/ roughly 14lb boost.

Worse yet, 824whp isn't 1000bhp, its more like 950bhp. I think Hennessey is stretching those numbers a bit and rounding.

A little off topic, but does 708whp seem right for my mods? 2018 ZL1 A10, meth, e40, dsx flex kit, Kong ported blower, 2.3 upper, Kooks longtubes with mid pipe.

Wonder how charge temps compare between the two at say 15 psi

My money is on Magnuson

He's also using meth so you don't know how aggressive the tune is.

Incorrect. 824 rwhp through a stalled auto is about 1000 flywheel horsepower.

stalled auto is roughly 17% drivetrain loss, which is 830 rwhp.
