So I finally got around to running a compression test on my L31 with TBI, I got from 225 to 230 PSI which seems a bit on the high side?
While I know a few variables can affect the compression test readings readings, I have a late model starter motor, good battery, tests were on a warm motor with the TBI unit held W.O.T. and the 8 revolutions per test.
Measured 9.6-1 compression ratio with a comp cams 252XFI HR-13 cam.
