Got my first 12 second time slip in my 06 automatic last night. 12.907 @ 104.87 mph. Sure a lot slower than my 98 Camaro was but fun.

Here's what it takes: C&L Race intake, SCT Pro Racer tuner w/tuning by me and Mike at Superchips, Granatelli radiator support, Power House aluminum driveshaft, CMCV deletes, MRT catted H pipe, an ASP underdrive pulley and an Addco rear anti-sway bar.

Here's what it doesn't take: I still have the factory 3.31 gear, torque converter, exhaust manifolds, mufflers, tail pipes and tires.

The C&L intake was worth .33 seconds. I reinstalled my factory air box before I left the track and slowed to a 13.241 @ 103.19 mph. Both intakes were tuned with the SCT. Traction was good on all passes.

 

12.90's is pretty impressive for only 104mph. You must've caught a pretty
good 60'. What tires were you running?

 

Thanks! My 60' was a 1.959 on the factory 235-17" Pirellis.

 

That is IMPRESSIVE, congrats!

 

Congrats on the 12 second pass, I hope to be there soon myself

 

I have a set of headers coming next week. We will see what they will do.

 

The '05+ GT's don't mph all that well, but they get down the track pretty
damned well all things considered.

Way to get every last tenth out of it Larry!
