Drag Strip Results 9/29/13

[Donald Gallimore <dongallimore@xxxxxxx>]

Did another trip to the strip today. Good air so expected some good times. Well, best was a 12.44 at 109 mph which is still 3 tenths and 2 mph off my best. 

Played with my shift points. Actually ran better shifting at 5300 than my usual 5600-5800 shift points. I could tell that the motor was not pulling past 5300 which is a lot less than the 6000 or so that worked before. Pretty much confirmed the dyno test two weeks ago where the engine quickly lost power past 5300. Looks to me like I need a ring job and a second look at the valve springs.

Could it be a fuel pressure problem or an electrical related ignition problem?  There are no signs of surges or misfires, etc. 

As far as an evaluation of the Rev-N-Nator ECU, I don't think this was a good test. However, I am not thrilled about the 1000 rpm steps on the rev limiter. For example, for me, 6,000 is too low and 7,000 is too high.
