hay guys just wondeing how much air to run at the track with i have M/T drag radials but was not able to hold 4lbs of boost , when i left the light the car almost went completely sideways on me. any ideas?
Light em up for about 3-4 feet. Then look at the marks real good. You want a good even patch of rubber all the way across the mark. Is there more rubber on the edges of the mark than the middle? Too little air. More rubber in the middle? too much air. My MT streets liked 20-21 lbs most of the time. The drags usually 15. Can vary a bit due to track temps, car weight, etc.
thanks guys, sorry they are M/T drag radials , great info guys , wheezer that is an awesome and smart way to figure out if i need more or less,
i just check the tire pressure and it was at 26lbs now i see why i went sideways
