I'm new to the discussion forums here, so I'll introduce myself. Hi! Anyway, I've got a stock 06 GC SRT8 and I'm planning to take it up to Atlanta Dragway friday night to make a few runs. I was wondering if anybody had advice for running on the run-flats. Should I leave the pressure as-is? Would 20lb's be too low?

Yeah way too low keep it around 33 on all 4, just go around the water if you can. Welcome to the site

I have had real good 60' times of 1.78 to 1.80 with the tire pressure hot at 40 in front 35 rear leaving at idle but thats at my drag strip all starting lines varry.

I run 33psi front and 37psi rear hot

Panic, where are you located ? I am just north of ATL. I would adivse you not to go to Atlanta Motor Speedway as it is a zoo on Fridays. You will be very lucky to make 2-3 passes. I would make the trip down to Silver Dollar Raceway in Reynolds Ga. Gates open at 6 and they start running at 7. You can get 5-10 passes in on Fridays and a dozen or so on Saturdays. Plus it sits at 445ft versus AMS at almost 1000ft. I would also not worry so much about the tire pressure as I would be concerned with icing the intake, pulling the abs fuse and launching from idle. Good luck !

I'm north of ATL too. But SDR is damn near Macon! I think I'll drive the 30 miles to Atlanta dragway instead of the 130 to Silver Dollar. What's up with pulling the ABS fuse?

Some say it nets better 60' foots not sure if it helps in the end result times. I just put it in autostick (1) and let it shift by itself and hit the TC button on the dash. Now the autoshift works good for me with my custom tune not sure how well it works on a stock setup
