644 RWHP / 604 RWTQ - VCP Monster Motor
Yep, a twin turbo supercharged 4.6L DOHC Terminator motor did 644 RWHP / 604 RWTQ on 17 psi boost. The motor is new and Wayne says he is headed to
725 RWHP at 20 psi boost at 6500 rpms.
My friend Wayne Presley "VeryCoolParts" dynoed his new motor today for the first time. This car might answer the question of "How much HP is too much".
Wayne is taking the car to the London Cobra Show so look for it. There is a lot of pipe work under the hood to look at.

We just finished a 434C.I. small block Ford for a customer that went into a Superformance GT-40 with twin turbos. It made 1050HP to the rear tires on pump gas with 16 PSI and 1230HP to the rear tires with racing fuel and 20 PSI. I would say that he should be able to take most people on the street with this thing.
I will see if I can get some dyno sheets on the thing to post and some pictures.
644 rwhp really doesn't surprise me...those cars are super easy to get power from. Usually you can get that much with just a Kenny Bell supercharger and the usual go-fast parts. I have a buddy with an '03 and it made right at 500 rwhp with the stock supercharger and no engine mods.

I had an 03 Cobra that made a corrected 529 rwhp on an Apton ported stock blower with stock exhaust manifolds. It had nothing more than a custom tune, larger heat exchanger, cat-back and CAI. Tons of torque but ohhhh... that clunky IRS.
