Yeah, you need to be on your game esp if the other guy you are running is faster than you. You went .2 slower than your dail, and the rest you can attribute to your 60' because (I guess fortunately for you so it didn't seem worse) he cut a similarly horrid light.
Pro Tip: Don't go when you see the light turn green. You will have to leave on a yellow. I think human r/t is like .050 so you will need to at least think about that, then how much rollout you have allowed depending on how you've staged to actually break the beam and start the clock, and how your vehicle moves forward as you let the clutch out/come off the brakes. A mediocre light with some practice should see you in the .700 range, and although its not good enough for the big classes, it can get you decently far with the novice street class. Remember that counts against your dail in as it is assumed you will run your 15.0 dailed on a .500 light.
If he wouldve cut a .600 light, it would be like he was running over a full second faster than normal between your dail/reaction time/60'. Then it will seem real crazy getting your doors blown off by a high 13 sec car.
In all, don't go switching your tires; work on your driving skill. 2k launches arent going to do shit but bog and then possibly break them loose when it catches itself and you have it floored. Sometimes you cant just floor it in 1st, and sometimes you have to ride the clutch out a little and practice what RPM you can do so at.
You have a full exhaust and an intake, so if someone knew what they were doing, they could run half decent. Your 60's were atrocious but your MPH (going from my LT1 experience) is still not too bad considering in the last few runs. So it might actually go up a tad if you can learn how to drive your car and bring it out with a 2.1- 2.2 60'. There is NO reason you can't do it. Mine did it BONE STOCK with 154k on it, on some half junk khumos. You can prolly appreciate my 14.4 @96mph a little more with a car so stock as to down to the paper filter

But like I said, that wasn't nearly my first pass out, and there was alot of driving involved.
Also, please
never ever ever mix-match a time slip again. They don't even make sense to read like that.
Hope you can walk away with something learned from your 1st track experience along with a little humbling and some appreciation of what others are running. I have a feeling there will be a tad less 'calling out' in the future
I remember when Bill and I used to fucking pw3n then the street and slick classes back in the day for streetwars. Sure wish I can get my car to be that consitant and hook again. I'd have to work on my lights again though. I remember when a .530 for me was like my worst light of the night, my 60' times were never over 1.75 and I could run within a hundredth of my dail or so near every pass. I always ended up redlighting or missing a gear or something retarded in the semis though. Nerves are a bitch. Too bad they never gave out 3rd place trophies

I know Bill at least has a 1st place street slick and a streetwars one though!

It whistles while it WORKS.
I suck.
