Never take things for granted

Today a new customer showed up with an Evo 9 GSR. Apparently his turbo blew on the way up to Sepang and he wanted to get it replaced; as he had some plans for more power the engine is being torn down and fitted with upgraded parts as well.

We were a little surprised that the static compression was measured to be about 9:1 instead of the widely acknowledged 8.8:1...

Bore85mm
Stroke88mm
Piston dish volume128cc
Cylinder head volume440cc
Head gasket thickness0.95mm
Head gasket bore85.5mm
Compression ratio9.021:1
