LSD has nothing to do with it...it doesn't create magical grip. On a flat, straight, well paved road, a LSD isn't doing squat. It only helps when one wheel is being oversped under load and the other isn't. I'll make a more relevant comparison. My car makes very similar TQ numbers to what RBs put down (491). And with PSSes, open diff and stock rear suspension, I never had a problem putting down power at 60mph, even 40mph, as long as the temps are above 40. If you are getting "wheelspin" at 100mph, 60mph, you are either feeling the flimsy rear toe arms/subframe bushings and perceiving their weakness/floatiness as wheelspin, a colossally screwed up alignment, an inability to drive, you hit a massive expansion gap, or some combination thereof.
Now back on topic.
