Have known Cobra Power, C & G originally, for many years down here and have always heard their HP ratings are very accurate.
In the mid-90s, when Paul Fiore was with Hustler, they rigged many with Randy's engines and Paul told me he was very impressed with the performance, so he felt the HP ratings were right on.

I guess I got confused about the 4 psi and 7 psi you stated?

Re: had motor dynoed
 

sorry they were not dynoed by cobra

the 1021 hp was at 6000 rpm showing 7 psi
the 1050 torque was at 4000 rpm showing 4 psi

they were dynoed by a very reputable and talented engine guru

I have aprox same amount of time on my 1100 Cobras, pretty easy hours (42 Fountain), the motors still pull like they where new. 705s, 1271 etc.

Why sell the blowers? Big cubes and low boost makes a powerful and reliable combo. If you want less maintanence, go to a mild hyd roller valvetrain.

Re: had motor dynoed
 

we dyno all engines complete with accessories minus power steering pump.

Re: had motor dynoed
 

I had C&G blower motors in both of my Apaches, and Tom Earhart said they dynoed right at what Randy claimed when rebuilt to Randy's original specs. :D

Re: had motor dynoed
 

Ummm, what's left after removing all of those?
