I'm confused. Are you saying you developed the web cam #73 amd Jake got it from you? |

Are you saying you developed the web cam #73 amd Jake got it from you? No, I'm saying that it took me a lot of R&D, including static and dynamic analysis to figure out the correct cam that I need. It so happened that webcam #73 was almost what I wanted but my math showed that 3% more duration on the exhaust will be very slightly better. That 3% is about 6deg but since webcam grinds the camshafts with 5deg granularity, this is what I ordered. By the way, I had to model the L-Jet flexible rubber boot between the AFM and throttle to accurately get those results. I also said that I'm happy to see that Jake reached the same conclusion with his cam, as this only confirms my calculations. |

Are you making certain assumptions as the baseline for the camshaft choice? Rich |
