Anyone ever do back to back testing with stock and then a bore'd out throttle body??

stock dia: 45.10mm

average overbore diameter???

I'm guessing 50mm, it looks like I could bore mine out to 53.50mm...hmmmm (IMG:style_emoticons/default/smile.gif)

motor to have higher than stock compression, custom R.A.T. cam and Megasquirt......
