both being the same exact size, only difference was 1 set were drag radials which are really sticky and the other set was a hard street tire. The street tire made 40 more whp, this was with javads 80 when it was making 700+whp.

woah, weird.... less friction = more slipping = faster revving?

No car was never salvaged only bumpers, drivers door and fender required respray.

Less resistance on the tire to the roller.

New vs. old shouldn't matter, but *different* tires might make a difference. So-called "whp" (bhp measured at the wheels) is affected by many kinds of losses between the flywheel and the rollers, and tire rolling resistance is just one factor, or could be.
