Hey Einstien, you'd blow the motor the same way racing from a dig or a roll, if your are the suck at driving and over rev. it.
It is infinately more likely to break something racing from a dig (trans, diff, axles)than from a roll. I know this from drag racing a car that was specifically engineered to road course race.
A 20 roll to 120 would be easier on the drivetrain but still leave you in the RPM ranges your car is geared for.
Tire wise, there are few here dumb enough to drive their car on the street with slicks. When putting down the low end torque numbers that Linn and the good Dr. are achieving, a drag radial on a 17/18/19 inch rim is not gonna give enough sidewall flex to allow them to hook well from a dig.
And finally, to you and douchebagging_in_ohio. Racing is racing. NAAAAAASCAR, ALMS, NHRA, IHRA, F1, et al. Unless your car is a purpose built, not street legal or streetable, tubbed, slicked, roll caged, fuel shut off switched, drag chute packing car, then you are just huge mullet-headed pussies for being skeered to go from a roll.
