I ran the quarter mile yesterday after 2 years of doing it. my best time was a 15.033 at 92.6 MPh 60' 2.43. Last time i ran two years ago i ran a 14.85 the only difference was that i had an intake/exhaust before, but now i only have the exhaust. My trap speed was lower 90.1 mph. My mph is higher now , but my time is slower.....

I used to launch the s2k at 6800, now i'm launching it at 7500 or i will bog down, i don't know if it had to do with the resurfacing of the flywheel when i got the clutch changed. I lowered the pressure of the tires to 24 to help with traction.




Also, i'm located 4500 ft above sea level to the people wondering my time is so high.

any input...?

 

Trap speed is a better indicator of the power being made. I think you're fine. I wouldn't worry about a less than 2 10ths difference in E.T. If your trap speeds are consistently higher than before you're make more power than before.
