Help w/ 1/4 mi. Times

A slight change in weather conditions could make a big difference on your trap speeds. That could explain the marginal difference before/after mods.

Given your 330' and 1/8th times I'm guessing your 60' times are in the 2.3-2.5 range.

How are you launching? Are you dumping the clutch from 2500-3000 RPM? If you are, try to slip it instead so you can manage the power you are putting down for less wheel slip on the launch... and practice, practice, practice!

500' above sea level isn't too bad, but given your humidity issues I think that you might be looking at low 100 mph traps on a good day. You very well could be running mid-13s in better conditions stateside, which is about average for a 6MT Z, but I have a feeling you should be running a high 13 or 14-flat if you can improve your launch.

Your probably right about the 60ft. but you need to understand that there is no track prep at all. Everyone here needs slicks or DRs in order to get off the line the right way here.

As far as technique I'm dumping the clutch but feathering the gas till it grabs in first.... I have cut constant 1.8 60ft. On street tires with my 91 turbo mr2 back in Sacramento Raceway California and steady 1.5-1.6 on slicks with my turbo RSX type S that ran 11.2 so I know it's not that big of a learning curve as I'm not green tonthe track..



My problem is why ain't i seeing the difference in mph trap even with shitty launches? Shouldn't i I see a difference in time at all? What gives?
