Not a wealth of knowledge, I'm new to the motor. I am using a 96 contour Zetec in a vehicle that has a total weight of <1300Lb. I would like some more power as I am classed in a group of vehicles that have over 250 hp at my local road race track.
The coefficient of drag of the car is in the 0.70 range
, so my top end is nothing to write home about even though my 0-60 is in the low 5's.
I was advised by an extremely reliable source on this board that the c/chamber vol is 47.7 cc. so I'm on my way to calculating how much shaving is required for various compression ratios.
Mark.
