Calculating Horsepower

I am just wondering how many people have broken TKOs, or similar, transmissions driving on the street or on a road course. It seems to me, in my ignorance perhaps, that you are not going to break the trans because you couldn't hook up that much torque and hp on the street if you tried. Unless of course you were running big drag slicks. I also think that without the shock loads of starting from a dead stop the trans should live. Banging gears at speed would produce some pretty high shock loads too so maybe that should be avoided as well. I dunno.

Bottom line: I know the TKO II is rated for something like 490 ft lbs of torque. Heck I am getting almost 700 ft lbs from my engine and running it through a regular TKO. I believe that not drag racing and not banging the gears really hard while on a road course should allow my trans to live. Then again if you can afford a better/stronger trans, go for it.

I can't wait to see the engine with those Webers and see how it all works out. Yes, I sometimes dream of running Webers.

Added by Jim: 591 ft lbs at the rear wheels at 3500 rpm, assuming 17% loss through drivetrain yields 692 ft lbs at the flywheel at 3500.
