Default Dyno question?

This is probably a dumb question but here goes. When you get your car dyno tested which horsepower does it give you? rwhp or at the crank?

It gives RW HP; if you divide that number by .85 you will have a very good approximation of CHP.

It gives RWHP and RWTQ.

There is a certain amount of power thats lost through the rear and transmission due to friction, typically you can use 15-16% loss for manuals and 17-18% for automatics at the power levels we reach. Technically though, its not a percentage, but thats another huge discussion that you could find in the archives.
