If you think your engine is wearing a little to fast then perform the following tests.
1) Compression test. There should be no more then a 5% difference between the cylinders. I would expect 135-170 psi for your set-up. 2) Cylinder Leak Down Test. Should be no more then 12%. The less the leak down, the better. Not to say that 12% is bad but thats about the most I would like to see. Mine is at 0-2%. It is also possiable the the difference in air and traction played a role in you MPH. I would also agree that you are running a little to much fuel pressure. I would say 36-38 psi with NO vacuum signal. Good Luck |
