This is a chart form the dyno done today it's a comparison of the cams activating at 4800 and 5100 respectively against an engagement of 6300 on both.

Wow those high lobes suck. But yeah looks like you have them switching in a good spot. Looks like a smoth transition.

I myself was dissapointed with the resulting HP and Torque figures. The low cam i must say did well but was expecting more on the High side. AFR was around 12.0-12.2.

I think you're dead on with the 6,300 switching point.

The 20V low lobes are great, and the high lobes are only slightly better so I think your results are typical. That's just the way the cookie crumbles.

That's a very silly statement... it all depends on the motor. For examle my motor also makes the most power with the afrs in the mid 12....

But usually stock motors like it leaner.

@ Cory, point taken, should have asked more questions before posting that "silly" statement

@ speedracer, whats the complete motor setup like, was it tuned on the dyno, and what type of dyno is it?
