You can do the math, the 4.33/4.10 = 1.056 so 5.6% increase in acceleration and a 5.6% penalty in top speed.

Though, it'll feel quicker, because you spend less time in the low end.

Which 4.3 R&P are you getting? I think Mazdatrix's or Racing Beat's is a 4.375:1.

Torsons are planetary gear sets, stronger than any clutch or viscous diff by design.

The GM turbo 400 trans is basically some fluid, a case, and 2 planetary gear sets and people use them in 1000hp drag cars because of the durability of a planetary gear set.
