4.10 vs 4.3 in 20B N/A FC

You might break the Torsen with that much power and the added torque of the 3 rotor. I would still test it and if that doesn't work, there's always the viscous. How's the condition of your viscous LSD though? How many miles?

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.
