You would have to experiment, but i would go between 10 to 14 psi. See what works best for you.

Those are excellent 60ft times. Were they on slicks? Also noticed that you have stock suspension. Don't push it to hard, if you are regularly on the drag strip. Torque boxes can't take that much punishment without some reinforcements

I agree...between 10 - 14 psi. It's going to vary depending on track conditions.

Thanks guys; but 10-14 psi on a cold or warm tire?
I've just got my sub frame connectors and hop this will help my 60 ft times.

Anything to stiffen up the chassis will help launch the car. I run my MT's (10.5) at 10 pounds regardless of track conditions. Always do a good burnout on slicks.

When you mentionned 10 pounds pressure in your MT 10.5 is it 10 pounds when the tires are warm or when the tires are cold????

When tires are cold. Make your last measurement...do your burnout...a rule of thumb is every 10 degrees the tire heats up, another lb. of air there is.

What kind of suspension work can preserve the torque boxes?
