Standard radial tires don't provide much more traction when they're heated up with a burnout. However, when you heat up drag radials, they provide a lot more traction than they do when they're cold. But a 4,200 LB car that's equipped with a centrifugal S/Cer, probably wouldn't benefit as much from drag radials as a roots S/Ced car would since the roots S/Cer provides more acceleration off the line. And that's why it's to the advantage of the Procharger Marauders, that the race rules ban drag radial tires. Because the Trilogy equipped cars will benefit much more from drag radial tires than the procharger cars will.
It's the same as if you proposed a rule that both cars had to have the RPM's limited to 5,500. That would give the advantage to the Trilogy equipped cars, since the procharger cars have a greater percentage of the power gains above that RPM level than the Trilogy cars do. Because most centrifugal S/Cers don't begin making some serious HP until 4,000 RPM's, whereas many roots S/Cers are making some serious power by 2,500 RPM's. And BTW, a number of people (including myself, Lidio, and Dave) run drag radial tires on the street. That's the whole purpose of having racing tires that are "Radials". because they're intended for both street driving as well as the track. if they weren't, then they wouldn't be radail tires, but would be wrinkle wall slicks (which they aren't).
