I did some power tuning of my cam gears this weekend and was questioning a couple of things. First is my method of testing. I used a stop watch and did third gear acceleration timing runs from 2800 rpm. to 6400 rpm. I did two runs with cams set at 0,0 to establish a base line. These test were done back to back on a very quite section of interstate so no laws were broken. The adjustments I made to the cam gears were done in 2 degree increments. Back to back runs on the same section of road after each adjustment. After four different adjustments I found one setting that knocked off 2 tenths from all the other settings, intake at 0, exhaust at -2.
First question: Without going to a dyno, is this a valid method to get in the ball park.
Second question: Are 2 degree adjustments too big? Should I have done more tests with smaller adjustments?
