When I mess around with Desktop Dyno, I definitely get a greater power gain from a dual pattern cam.
I used one of the DCR calculators online. It seems with my theoretical combo, I was at 7.5. However, if I bumped my static compression ratio up to 10.75, I was around 7.9. I think that's about the limit for DCR and pump gas.
So how do you know if you're right? How reliable are these calculations?
10.75:1 seems awfully high....even with the cam that I have picked out. Sure, it's got a high duration, and the intake valve stays open quite awhile.....but 10.75?
Part of me wants to try it....part of me is scared.  |
