But after my 1/8 mile run my oil pressure at 70mph was lower than normal. Usually it is slightly above the 3/4 hash. Tonight it was slightly below the 3/4 hash. I had a cut out pipe installed and was running with it open for the first time...cause only time I will have it open is at the track...what could be happening to cause my oil pressure to drop with the cut out open? Thanks.
