9-1/2 convertor is more street friendly
8” convertor is obviously more loose and you have to think about pulling out of a parking lot or Dunkin to accelerate
Doesn’t matter which gear or convertor is in the car……..@ 45-50 mph in manual 2nd it break the tires loose
No doubt! I occasionally replace the Drag Radials with regular 275 street radials for a true radial class at our track. It is downright scary when you jump on it at the top of 2nd gear on the street!
How does the car run and handle on the track with the 'regular' radials? One of my local tracks has a class like that and everyone wants me to run in it. Seems to me like it would be an ice skating rink.
Not bad at all. I run Mickey Thompson Street Radials and they like 20-22psi. I leave in 2nd gear and put 100+ lbs.in the trunk over the rear bumper. Managed 1.72 60 ft. on a prepped track and got runner up in the last race. Typically runs about 11.70's on that setup so I dial a 12.0.
The car goes straight as a string and works really well leaving off idle.
