sorry about that !!!!!! I should have said,,, AND ,,, not BUT
No worries, all good
And again I do agree but if we go off of what's been said, that it rolled 315/350 on a chassis dyno and then proceeded to trap 89mph....... it has to be down 150 crank horsepower or so?
I think a huge difference that -can't- only be attributed to a dual plane (in my opinion).
Still want to see the dyno sheet but it's soooo horribly far off my only ideas are-
-it has massive fuel pressure drop/starvation
-it burned a plug wire or 2, dropping cylinders which would result in false lean numbers on the wideband.
Most useful thing aside from the dyno sheet would be a data log. For whatever reason doesn't exist, should be easy to obtain.
