I've been doing a lot of research on Somender Grooves. The results seem to always point to a FE increase, so I think I may try it out on my '93 accord. I paid 200 dollars for this car, it has 274,000 miles on it, what's there to lose?
My question is, do you lose some compression when you do this? And if so, would it be advisable to mill a bit off the head to bring it back? In fact, could I take the opportunity to increase my compression from what it is now?
