How much HP and torque can a stock C4 reliably take? What does it take to make a C4 withstand 600 HP and 600 ft/lbs? Just a whimsicle question, but is there any automatic transmission with overdrive that will reliably take that amount of power?

Also, I remember reading somewhere about a year ago about a test of how much HP it took to drive various transmissions, and the C6 was up at the top of the list.

I'm not sure, but I seem to remember 30 HP being a significant number, maybe 30 HP more to drive a C6 than a C4? If anyone knows those figures or has a link to the article I'd appreciate it.

hp- loss

A rollerizer C6 the hp loss is a little higher that a C4 but the releyablite of the C6 makes it well worth the HP loss , my C6 live at 7.80 @178 mph
