Can any one do high boost launches on MT DRs? Whats the secret?
I can make 12psi boost on the foot brake but the MT DRs 275/60/15 cant hold it and get blown away. They seem to stick at about 7-8 psi launch max.
18-20 psi in tire gets same result.
Am I asking too much of a DR?

What kind of PSI you running? Have you tried adjusting that? How was the track prep? Was it a TNT where everyone was blowing there tires off, or were others making good short times?

It was a TnT during a Bracket race event. Lots of cars with slicks. Both me and another TR driver with MT DRs was only able to launch with 7-8psi boost. But that’s was about it. Similar for other nights.
He runs mid 6s, and I high 6s in the 1/8.
The slick cars had no problem.
