Dyno is right on. Each one is different and each one acts it. I knew our roadster would never spin and it didn't until we put in 700hp where 300 hp use to be and it spun at 175. We were at Bonneville with not a lot of ways to fix it. I asked my son what happened first and he said it went slightly right, then left, then a big right. I added 1/8" to the right side length and he went back out had set the record at 186; went straight as an arrow according to him. Next year 196, next year 202, next 216. When the car ran out of HP at 215 it was a hell of a ride and I just hung on. we did add 400 lbs after the spin.
Running out of HP causes crazy things to a flat face car; they don't like it and they tell you. If you try to drive one at part throttle to get your licenses you may quit. Driving a twin turbo smallblock roadster at 150 and 175 can be an eye opening experience. The key is to accelerate slow and just get to the license speed not hold it for a mile.
Others have said if you have a locked rear and spin, take it out. If you spin without one, put one in...Good Luck
