I don't understand why you think your trap speed is off. It seems pretty consistent to me. With my new Hoosiers, I was trapping almost 126 MPH with my 11.5 ET. My speedo showed 135 MPH as my front tires broke through the 1/4 mile gate. Correcting 5% for the shorter hoosiers, that's still over 128 MPH. Your trap speed doesn't seem far off to me for an 11 sec ET. These cars accelerate quickly on the big end.

Thanks a bunch Cal. I see you're heading in the right direction too. The reason why I say the mph is wrong is when comparing the time slips from both lanes, every interval matches up, including the 1/8 mph, it's only when you get to the finish line that the mph doesn't match up. These cars don't make the power on the top end to pick up 32 mph after half track. I think anywhere from 25 - 27 would be more in line with what we would see. Maybe the 1/8 mph is low...I don't know. I have run 101 in the 1/8th at another track, and 129 again at another track. Who know... I'm just more excited about the 60' and the et.

I got my 1.72 with 26 PSI, 5 sec dry burn out, PTM Race, 1700 RPM, 10% slip on launch control.

I run with all nannies off. Race mode, then hold the tc button for 7 seconds until everything is off. I don't go through the water, I back onto the edge of the water box and then do a decent burnout. I foot brake it to around 1k and launch it by the seat of the pants. I generally roll into the throttle before going smoothly, but aggressively to the floor.
