Last night I borrowed a beaurette and measured the CC of the bores and the volume of the dome part of the high comp piston so I could confirm the final compression ratio with Guy croft. He will be skimming the head to get me a CR of 12.2:1. Looks like I'll be on super unleaded from now on.  I am starting to get serious withdrawal symptoms now, just want to get her back together asap so I can drive it again... ________________________________________ R H Davey Welding Supplies.

Good work. The std combustion chamber in an unskimmed head is 35cc IIRC. |

I may end up with more compression than I need. I'll double check my figures tomorrow but I'm pretty sure we needed something in the forties combustion chamber wise. ________________________________________ R H Davey Welding Supplies.

No, they poke out of the top of the deck by 4.5mm, so we brought it back down by 10mm exactly, measured the volume at that position, then subtracted that from the total, or something like that, I have the formula written down at work. However we got our figures they are spot on as they were confirmed by Guy Croft who double checked all our calculations with a formula he has on his PC. I estimated the compressed thickness of the gasket to be 1.2mm and that was included in the figures too. I hate maths   ________________________________________ R H Davey Welding Supplies.

Perhaps mine had been skimmed, I think the std piston crown was 15cc and the 1.2mm std MLS gasket works out to 7cc |

That's not that far of a diesel is it? Of topic I know but what was the octane rating of 5 star petrol? ________________________________________ My old man wrote me a letter from prison once.

I think the standard head chamber volumes are around 38cc in the head alone.Jim - I wrote an Excel spread-sheet for calculating compression ratios on this engine for when I was building my engine [and others]. If you want I could pop over one eveing, could plug your figures in?  ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |
