Newly instlled boltons on my L99 - Improved 1/4 mile times

I am a newbie at the track. I plan on going to the LS fest and needs some pointers!

I finally got to the track with all the boltons. Vmax ported TB, kooks header with hi-flo cats. K&N with apex scoop and a street tune. I expected little better times than my latest run compared to my initial stock run back in April.

I am now spinning on launch and the next two shifts. That shift into 2nd has a pretty bad spin but I'm not sure how to eliminate that unless I turn traction control on.

Does the temp outside affect traction on the track???
What kind of improvements do anyone think I will have 20 deg cooler similar to my stock run??? 2 tenths???

DA has a pretty big effect on et and trap speed. There are calculators that can estimate your recent time in better DA like your previous runs.

Spinning issue you can try dropping tire pressure, doing more of a burnout or running with TC on. Every car and driver technique is a little different have to see what works for your setup

Generally will run a tenth slower for every additional 700 in DA.

I'll try lowering the back tires to about 28psi. Maybe increase front tire pressure a little. BTW, I held the traction control button down for 6 seconds until everything shut off for one run. That was a mistake! Thanks for the input.

Yes. bfgoodrich comp 2. I probably should invest in a set of rims and Dot Dr. For one of the compitetion at holley ls fest you need stock size wheels and stock size tires though. How many tenths are DR good for with my numbers?

Best I went with the mods in your sig was 12.7 on street tire, and then 12.3 on a 20" 555DR which is not the best hooking DR out there.

Yeah the bad thing with street tire put to much heat in them they get greasy.

When I ran 20" nitto 555dr had to heat them up good I cut some high 1.50 and low 1.60 with them.
