Mods are in my sig. I am running 245/50/16 KDW on all four tires. Temp was about 80 in Gainsville, FL. My 60ft was 2.197, 1/8 mile 8.714 85.64mhz, 1/4 mile 13.272 108mhz, R/T .302 What is R/T?? With my mods I was really expecting high 12's. I dont know if i had a bad start or not. I dont know what a good 60ft time is?!? Can anyone tell from this if this is really as good as I can get? I dyno'd at 350rwhp after all the mods were complete. I went by myself for this first time so i wouldnt feel bad if I screwed up to big. Any info would help. Thanks

 

It is mph, not mhz. That would be megahertz. Your 60 foot time is the problem. A good 60 foot time on a street type tire is a 1.8-1.9. Generally every 1/10th you drop in the first 60 feet equals 2/10th's at the end of the track.
So in theory if you could hook and get a 1.9 60 foot you should run close to a 12.5 in the 1/4 mile. Do you have a 6 speed?
R/T is reaction time. It is the time it takes for the light to turn green, and you to break the beam at the starting line.
It has nothing to do with running a good time.

 

What he said except that 1.8 60's are hard to get on street radials. But if you could get a better launch and 60' you'd easily be in the 12s

 

Sorry about the mhz. I work on computers all day long and I get use to typing that in. So my reaction time looks like it was pretty good, right? I do have a M6. I tried to dump the clutch at 3000rpm but all I did was spin. Then I tried to just hit the gas when the light turned green, and thats when I got my 13.2 in the 1/4. Is there anything I can do or learn when I am there trying this again? I will invest in DR soon but I was to see my personal best before I get them. Thanks

 

Drag radials will be the minimum required to hood a 6-speed car. Street tires are usually horrible at the track.
