Gasoline and CR
By John - 01/12/2003 10:49:53 AM; IP 142.177.114.3
The specs from teh 60's were for higher octane gas than what we get these days, or at least I'm under that impression. So those high CR specs don't apply today as they only cause trouble. Now CR alone doesn't increase Hp very much. What it does do is allow the use of a different cam matched to that CR. The two working together is what makes things bark. I'm using FPP 9.5:1 pistons and a Crane solid lifter cam designed to work with that CR. I eally don't know what to say, but with a 2500 lb car I just can't put the pedal to the floor without all hell breaking loose. I dare say I have more Hp available than I'll ever use. Remember Hp is the work being done...sort of an achievement. So in a light car at highway speeds, it's more fun to build in low end torgue and not get carried away with what the engine could do at 6500 rpm in a 3500 lb car at 150 mph.
This thread, so far...
