[Five Oh Brian]

It is surprising to bend them at our hp level i think brians around 11.7 area. Iirc hes got that dam heavy glass roof add in some leather heated seats and these are heavy pigs that shafts moveing

Yes, 11.7's-11.8's. And, my car is about as heavy as they built from the factory with nav, glass roof, shaker stereo, heated power leather seats, 19" wheels (factory 18x8's on race days), etc. Car weighs 3620 + 180 for me = 3800 lb race weight.

Pentalab is probably right. Steep 1st gear + 4.10 gears + 5000 rpm stall converter + sticky drag radials = a whole lot of torque multiplication on launch. I've probably made 100+ 1/4 mile passes in this car and something was bound to wear out.
