No, I go by flywheel horsepower only. A Cobra has a terrible amount of parasitic losses through the driveline and through the exhaust. Some here have stated that they have removed the sidepipes and gained 100 rwhp. Some sidepipes are very restrictive.

It's easier for me to know what's going on when flywheel horsepower is mentioned. There are way too many variables when someone quotes rear wheel horsepower.

In my line of work, I get a lot of guys talking about 600hp small blocks and 700hp big blocks. I always ask to see the dyno sheets....and even then I take them with a grain of salt.
