Thread: Compression Calculator info

I was wondering why we do not have a stickey , in regards to deck clearance , head cc's for all the varraints of the SR motor in one place and a link to a Compression Calculator so we can put in the ino and head gasket thinkness , and bore , so we do not have to dig all over and it would just siplify things for some of us .....

somthing like basic specs ....

86mm bore
86mm stroke
head cc 's ( DE, GTI-r or VE )
and all other basic info so we can all use this info to figure out our compression

with somthing like this ...
Engine Compression Ratio (CR) Calculator

I thought there was a thread like this with all the info. As for a calculator just whip one out from your desk

Pretty simple those calcs.

I dont know the forumal ...do you ??

Good place to start capturing your basic information...

r = (Vc + Vd)/Vc

Vc = clearance = clearance + gasket thickness*(pi*bore^2)/4
Vd = swept by piston = stroke*(pi*bore^2)/4
