calculating new engine displacement
So after an .020" (.5mm) overbore and lowered compression ratio with supertech 8.6:1 pistons, I realized I need to update my REQ_FUEL on my megasquirt. I was thinking, oh, I'll just use the REQ_FUEL calculator in tunerstudio....
then I realized I don't know what it is anymore.
Stock BP 1.8 is 1839cc. Overbore to .020 with stock compression pistons is supposed to be 1862cc according to this thread
http://forum.miata.net/vb/showthread.php?t=323324
but then I have lower compression pistons. Is there a quick way to figure this out? or should I just leave it as stock displacement?
