I drove the car every damn day. Also remember, the only reason it was 710 and not more is I was limited to the fuel flow of 1000cc injectors.
THAT same set up with 1600cc injectors, and C16, VP Import..ect would be good to 900whp, so that MAY work out for CHP?
Now to the OP- are we talking in a car running, or sitting on an engine stand?
