Bored drinking my morning coffee...... what you guys running for tire pressure in your dragsters for your et's?

6-1/4

5.7-6.2 with almost no difference at all

Michael, I will just remind you that tire pressure gauges vary greatly. There is no right gauge, only your gauge.

^ bingo....i have 3 gauges, none read the same.

This is true .

When I ran the 3190 on a 4.7x dragster 6.5 psi seemed to be the happy spot

Timing lights and tire gauges some read different so stick with one and do not change. I have seen quite a bit of difference between two good gauges.

Also different weight of car, shock settings, 4 link settings, track conditions and other things may change what works best for your car.

For years I was told on a SBC you have to run 38*-40* degrees timing. Well mine works best at 28*-30* and it is easier on motor. So what others run may not be best for your car. Same with tire pressure what others run may not be best for you.

5lbs….

I ran mine at 5.4 in a 4.40's car

Ran 6.1 to 6.3 on a 4.50-4.60 dragster and a 4.80 dragster using a nice digital gauge

Ran the same pressure with the 3190 and 3191

so there you go it doesnt really matter.lol
