As usual, problems at El Mirage. A short connector was missing from the longer connection for the F.A.S.T. EFI, so unable to communicate to engine. We decided to run anyway and hope that tune was right. FAST EFI will correct air fuel ratio 20%.
We recorded the run and will be able to see boost, rpm, blower air temp, throttle position, ECT as soon as I can locate that
connector.
We made a run out of the 200 mile lane about 60th to run. Sounded good Troy didn't full throttle it until 3rd gear then engine
stopped short of finish line. Haven't looked at video yet to see how far, but Troy thought about 1/4 mile. Time of 147 coasting through
finish line. Troy though it felt like a broken blower belt but when we took off the hood, belt was fine. A small burst panel about the size of a quarter was blown out,[ there are 6 small burst panels on Wilson burst plate]. Took off valve covers and found broken exhaust rocker arm at #5 cyl. Hoping just from fatigue as rockers are several years old. plugs looked great but #4 looked a little oily, and compression test shows down about 20lbs.
Upgrading to Stage V top fuel rockers [ big bucks]
