They did a couple of pulls and noticed that it was pretty close as far as the AFR was concerned. They even bumped the timing up a couple of degrees and picked up a few more horses!! (Terry, in the video, said it picked up 20, but it was actually 13, plus they ran it to a higher RPM) As a side note, when we had the motor at the dyno shop previously, there was no attempt to adjust the timing, which might have put the motor over 500 HP??!! Another thing that’s puzzling to me is the discrepancy of both the engine dyno and the chassis dyno. I know that you can’t really compare the two, but to have 549 on the engine dyno and what we ended up with here, 402 at the wheels, seemed like a big difference. They did mention that it was a pretty “bad air” day, so that might have been the problem?? But, as you’ll see, I’ve got another “problem” to contend with now.....
