The issue i have is the torque. I hook out of the hole but 30 feet out blaze the tires once the weight transfers back to the front. And because the car weighs almost 4000 lbs, I have to run 13 lbs in the 9" slicks. Tried 10 lbs which helped with the traction but made is unstable driving the top end. After 4 years of fighting it i determined the blowers make awesome street cars and work excellent racing it in a chassis car
