I agree with him to an extent. The BB blower cars are hard to deal with in radial too. With that said though, I feel guys are figuring out how to make the turbo's work in the 1st 330 now. I still don't think they can run with a screw blower in large tire racing but for small tire stuff, the turbo can get it done.
Just last weekend. A turbo mustang on stock suspension and 325/50 radials went 1.16 and 1.18 to the 60 foot. That's something even a blower car can't say, even the n2o guys have trouble matching that.
