Re: Hard tail dragster problem
 

Thanks for all the info, Guys.
We have a VW powered altered and I keep arguing with my son about tire pressure. I can plainly see the tires wrap up on the launch @ 4 1/2 #. It barely spins on launch but it does spin hitting high gear. It's a turbo so we can hear the tires over the motor. It gets a little squirley on the top end with that low tire pressure. We ran 8.06 @ 168 with the little motor and are trying for 7.50's with a new and bigger motor but I want to go with higher air pressure and we put a 33" tire on it.

Mike, we get tire shake at 5#, that's why the kid went down to 4 1/2.

We ran 4 3/4 with a sbc and hard tail, now a four link with an iron head bbc 5 1/2. I have had the same problem while visiting a different track. At the pressure we used at home it would wad and then spin. I saw other cars doing the same thing the same day. We use the Hoosier 16.5s x 33 also.
