yell03 Posted February 24, 2014 Report Share Posted February 24, 2014 Last minute I decided to go to ATCO today with my 2011 GT500 Convertible with a 2013 TVS swap making 590rwhp SAE.Temperature outside was upper 50s and sunny, not mine shaft air, but nice conditions.I pulled right off the Highway, went through tech and right in to the staging lanes.I aired my Michelin A/S 3s down to 28# and decided to do an easy get acquainted pass.I launched off idle and cut a 2.18 60'.I short shifted to 2nd and immediately got locked out by the infamous 1-2 grind, so I let off and grabbed 2nd again.This resulted in a 8.84@94.18 1/8th mile.From there it was smooth sailing and the car pulled like a freight train through 3rd, I shifted to 4th and my virgin pass was a 12.93@122.93.This car amazes me, 122.93 after missing a gear.Unfortunately my day ended after 1 pass, a I felt a vibration on the highway and I thought my wheels weren't balanced properly, unfortunately a nasty pothole the other day caused this on the driver side front and rear wheels, I can't see how I didn't notice this... Knowing my car could easily trap over 125 on a clean pass I didn't feel this was safe, especially with the bubble in the front tire. Luckily nothing happened on my pass.On a side note....My buddy's 660rwhp GT500 ran a 11.9@125 on a 2.0 60' and a 12.2@128 on a 2.3 60' also on A/S 3s at 28#.My 18 year old son ran his 2005 GT manual tranny to a 14.1@103.9 on a 2.3 60' on crappy Goodyear F1s.Time to get some new rims and get back out there.Maybe a new shifter too? I think I figured out why I am getting the 1-2 grind and lock-out... I don't power shift, but I do lift throttle shift very fast (speed shift). I actually shift in to the next gear before the clutch pedal ever hits the floor, I have always done this in other cars and had great results. I think in the GT500 on the 1-2 shift I have to deliberately slow down, make sure the clutch pedal is to the floor, then shift 1-2, on the 2-3 and 3-4 I will speed shift as usual.
