Okay my mods are in my sig. I was running 25psi in my MT DR's 32 psi upfront on the Nitto Street tires, 20psi in the dragbags, and I launched from 2500 rpms to off idle (the last run was at 2500rpms). All the runs were done N/A and this is on my new replacement engine with approx 2.5k on the odo.

run 1

60 ft 1.8
1/4 12.7 @107

run 2

60ft 1.789
1/4 12.5 @107

run 3

60ft 1.732
1/4 12.4 @107

Any suggestions on improving these times would be greatly appreciated.

 

I'd try and lower the psi in the rear. I believe M/T DR's like lower pressure. Try somewhere between 15-18psi. When you measure tire pressure if the tire is cold add about 2psi. Cause once the tire is warm it typically adds 2psi. For instance I set my tire pressure at 10psi. So after my burnout they are around 12psi. Also, is your front sway bar still connected? if so, disconnect it to help weight transfer. It will give you the ability to launch higher. Good luck. -Mark
