New Track Times
Went to the track yesterday with my fully loaded GTA. Just as I drove it in off the steet except for the MT ET Street radials. Air filter in place and fully California smog compliant. My previous best was 13.30et and 103.50mph. My new best is 105.85mph and 12.73et. This is with TPI by the way. Allen

Mods are Trickflow heads, ZZ9 style cam with 1.6RR, highly modified TPI, custom cold air intake, SLP Tri-Y headers, custom exhaust, Yank SS3600 torque converter and a lot of little mods including a 52MM throttle body. Allen

60ft was 1.71. Lot of 4th gens with higher trap speeds but I had quicker et's. Hoping to line up with some or a Mustang but it did not work out that way.
With the TPI I can get them off the line and I have enough power on top to hold on until the 1320 line. For most of them anyways. There were a couple out there that are really modded and they could run me down by the 1320 line or just flat out beat me.
