Jochem Good morning Jochem if you are still following, My woes get worse, using a dial gauge I measured the cam lift as 21.65mm which i think is well below standard, maybe this indicates a regrind ?. Any thoughts ? Richard.. Quote Link to post Share on other sites
Stagpowered Posted December 1, 2019 Report Share Posted December 1, 2019 I think you have miss measured something, cam lift will only be 7-8mm with 10-11mm lift at the valve Neil Quote Link to post Share on other sites
SpeedFreak Posted December 2, 2019 Author Report Share Posted December 2, 2019 Yes thank you Neil it was a typo, it should have been 0.2165 lowest to 0.2185 inch. The die is set, the whole lump is coming out now for further measurements etc. Richard.. Quote Link to post Share on other sites
JochemsTR Posted December 2, 2019 Report Share Posted December 2, 2019 as I mentioned, your power of 103 bhp does not match compression value of 185 psi.....with only 0.2165 it confirms this...... check a few more just to be sure it is not just one cylinder.
