How much does your car weigh? My car is 250 pounds heavier than the ZL1Atlanta. I like to eat!

Spark ramp plays a huge part in getting the launch down with these cars, especially in first gear. I've done several other things since then and I think they all contribute to where we are now. Things like solid cradle and diff bushings, removing or disconnecting the front sway bar, and getting the air pressure right. With the 17's I had the best luck when the track could hold 18 psi, but would usually start at 15.5 and go up if I could.

It was 4,180 with me in it when I was on the 17's.

Did it run in the 8's on the 17's?
Your car is quite impressive to say the least! Great Job!

Thanks! It did not, it only made 990 when I swapped to 15's, so not quite enough power at full weight. It ran a 9.40 on 17's when it made 920. We've learned a lot since then to where I think it could have done 9.20's on that setup, but I don't sit still for long. Lol

Lots of seat time with logging/adjustments are a huge part for sure. Back when I had the 17’s I would drive 3.5 hours each way to the track to test and log. Sometimes twice a week. Hope to jump a spot or two after this weekend! Haha Sent from my iPhone using Tapatalk

Do you power brake any or just go WOT from idle?

We were at 18 and could only hook the car on the first pass. Mike pulled timing after the 3rd run but we never got to make another pass. Not sure if he pulled to much but we can put more back in on the launch when we run next month on the 15th of October.

So the 15” beadlocks I ordered back on February 1st finally arrived…! If anyone is questioning the upgrade over 17’s, these pics should put that to rest! The 325/50/15 setup is some serious beef!
