Increasing W10 Avenir Compression
(I've searched a fair bit and have mainly just have posted this up to make sure I have my facts straight so I don't blow my engine up)
Basically I'm thinking about raising my Avenir DET compression from the stock 8.5 to 9.0.
Not a big jump I know, but I like to keep things sensible , and it puts me between a DE and DET compression ratio, which I figure gives me a bit of both worlds
Since I already have a brand new stock head gasket in my possession, I don't want it to go to waste, so I'll probably get the head shaved.
So far I've found out I need to bring the head down .7mm.
(The great Mr Miko says 1mm = .7cr, so the maths says .7mm = .5cr)
What I'm having a tough time finding out though, due to conflicting info, is the thickness of the stock W10 headgasket.
Is it 1.2mm, 1.5mm or what
The other issue I'm worried about is valve/piston clearence when running cams.
With the loss of .7mm would I have any problems running JWT S3's or BC Stage 2's?
Thanks,
Clownie
