Nice 60 ft/times! There is a 60 ft/time thread you can now post your times in if you want to -

Once we get a bunch of data it will really help the community to see what combinations of parts works best to yield the best 60 ft/times.

On stock tires that has to be one of the best 60 ft's I have seen. You should post it in the Official 60 ft/times list:

OK going to the track tomorrow Ist time ever. Did search on how to launch for best times . WOW to much info that varies. So How do I do it .

Cant launch 2.272 60ft @ 12.911
On stock tires.

My first time doing runs was today. Was a bit disappointed. I have L99 vert. Installed Kooks LTs, Airaid, Borla S axle back exhaust and SCT tune from Ted. First run was 14.149 with 60' at 2.297. Second was 14.06 with 60' at 2.178. Third was 13.98 with 60' at 2.18. Temp was 83 alt about 1000 ft.

Used comp mode and S mode auto, didn't use paddles. Also had over 3/4 tank gas. All else in car is stock. SS RS wheels.

So is vert slower than HT to any great extent? How much did almost full gas tank affect run? Finally, staying in auto v shifters? I realize my launch has to improve. But wondering if these other points have an effect of up to a second in run time (or more?).

Thanks

The heat really hurt you. With teds tune, a cai, and headers I went 12.4 at 113 with a 1.89 60'. Start with launching better, 1000 Rpm worked for my car, then try again on a cool night. It will go much faster.

[Jakeman]

Thanks. Each of my runs improved. Will try again in a week or two and see if an evening run is better.

What track and whatwas your MPH?

Island Dragway in Great Meadows, NJ

102.66 on the 13.98 run and 102.89 on the 14.006 run.

R/T on 13.98 was .053 and .414 on the 14.006 runs

Corrected for a 2500ft Density Altitude (yesterday at Island), you'd gain about 3-tenths and 3 mph.

That's still only in stock territory for a Vert.

With headers and CAI, you should be much better. My guess is that you were pulling lots of timing because of the heat.

If you can, log your intake air temps, coolant temps, and look for knock reduction. You'd benefit from some tuning at the track.

Thanks. Next time I will try some changes. It was pretty warm as I was soaked after each run from heat in the car. On head to head runs, I won each heat, so maybe others were equally affected.

On the monitoring parameters, other than the in car gauges, how would you recommend that be done?

Did you get an SCT tuner from JRE? Or just the flash?

Otherwise, you'll just have to look at the coolant temp in-car.

You might also look into an OBD scanner like http://www.palmerperformance.com/pro...hone/index.php

Thanks for all the advice Padre.

SCT X3 tuner from Ted with tune for the car's present config.
