1mm 40thou

Interesting. I was talking to tbre this morning and according to my piston to deck height he recommended the 0.4mm one I had in my hand.

I guess I should have got my machinist to check this not just skim it during the machining.

He said I would have been way low on comp as I was using a 1.3mm gasket.

Being a dedicated e85 car I can't see it being a issue with a bit of extra comp once it's retuned.

Well looks like you have learnt lots this weekend gaz

Sarcasm?

No its just Jet and one has to get used to it

Im running 9.0 comp Manley pistons/Cometic 1mm head gasket and a heavily skimmed head leaving my dynamic compression at 9.2 which now thinking about it isn't that high....need to change my signature lol.

Lol yeah it seems these things love compression. Be interesting to see if it goes better, and how much timing has to change with the increased comp

E85 loves compression

If I had my time again doing the motor the only thing Id change is more compression with a set of Tony's custom CP slugs to get the number to 10.0:1 min.

Wasn't being rude either when referring to you Aaron I merely meant one need to understand how one operates when helping etc.
