compression/leakdown
I have a 94 GSR with 98k miles. compression is 192 to 199 with engine warm and throttle open. Leak down is 2% per cylinder. The shop manual says compression new should be 270 psi. Minimum acceptable is 140. My question is how do these nunmbers look and how much power am I losing being at about 200 pounds versus 270? this car is now used in SCCA road racing so I need all the power I can get. anyone got good idea how much more power the higher compression will provide.????
