Ranger has more detailed instructions somewhere. Ah, here it is! Search is a good thing! As a matter off fact, I just reread it and now wished I had done so yesterday, before I went back to the track. Oh well, I'll keep working on it!

I have run at ATCO many times before and went through the water box.
Even with only doing a quick spin in 1st to clean the tires my stock Viper GTS on stock tires cut a 1.89 60' and on R-compund Kumhos cut a 1.68 60' with the same technique.
My 2003 Cobra with 492rwhp on BFG DRs cut a 1.85 60' also with the same technique.
My Yellow 2003 Cobra cut a 1.96 and a 1.99 60' on stock tires with the same technique.
The one trhing I like about ATCO is that they don't soak the waterbox if they see you have street tires, so you can roll through the damp box and do a decent spin on the dry part right after the box.
The 19" runflats will be the limiting factor compared to the other cars that had 17" and 18" less stiff rear tires that were not runflats.

For comparison's sake I've got a 1.58 in my mere 335rwhp Z28 on drag radials after a serious burnout, automatic of course though.
Now I'm not sure if I really needed to do it or not but I cut that 1.88 in the C6 after literally baking the rear tires in fear of dragging that water up to the line, gotta be careful not to fling it up into the wheel wells either though so it doesn't 'drip back down' onto the tires as well.
But who knows, the TM 'delay' may've been the real reason why I dead hooked though LOL so I'm not sure.

They are excellent passes.
Did you cross the traps in 3rd?
My 1st two times running my 2006 C6 1LT resulted in a 2.30 and a 2.26 60', but I had lowered my rear tires down to 26-27#.
Finally on the 3rd pass I tried slipping the clutch and got a 2.02 60' and it knocked my times down 0.3-0.4 to a 12.55.
I'll bet with your car if you just lowered your rear tires to 26-27# and raised your fronts to 34# cold you would shave 0.1 on your 60' and 0.2 in the 1/4.
I didn't make my best pass of the day until my 3rd pass and my 4th and final pass was my 2nd best pass.
These cars are definitely a challenge.
Did you have TC off and how did you launch?
Nice runs!

I'm more impressed by his bone stock 11.24 then his 11.10 on DRs...that car (and his driving) amazes me.
