Engine builders offering 800 HP NA?
 

I remember seeing Paul Pfaff advertising a 598 with tunnel ram converted to EFI that made 800 HP. Anyone have experience with that engine or others like it?

Re: Engine builders offering 800 HP NA?
 

We do an 825 EFI that makes power at 6000 RPM's. The engine was designed for cats. It comes w/ a 6 month warranty, and is serviceable by any Mercruiser dealer.

How's it going hope all is well . We made an offshore first release in Feb. just after the boat show on a new MB800na based on a 632ci carb engine and we also offer that in an EFI configuration. All of our power is in by 5600RPM and the rev limit is set at 6000 this is a killer combo we've tested this combo for the past two years in the race circuit and I just sent two to Kuwait carburetors the guy loves them.Sincerely Laz Mesa
