Sorry, but you are inaccurate. It's pretty standard that the online community refer to cars power via their dyno numbers, not crank numbers. Manufacture brochures are the only media source that refers to a cars crank hp numbers (i.e. flywheel numbers). When someone puts a "W" it means just that...
to the wheels. No one brags about flywheel power, because it doesn't factor in your drivetrain and how much is making to the ground. Again, only Manufactures speak in flywheel language.
If I were to refer to my cars flywheel hp then I would sit there and add the 15% drivetrain loss commonly associated with FWD and say my numbers are 374hp/368tq (according to a dyno dynamics. According to a Dynojet then 419hp/413tq).
Crank hp for the FT-86 is rated at 200hp. On a dyno with an estimated 20% drivetrain loss for RWD vehicles it's going to put down 160whp ballpark. Notice 200
hp and dyno after drivetrain components 160
whp. That is if Toyota didn't under rate the motor like some Manufactures have done with cars before.
If you have had your car dynoed before, 9 out of 10 people refer to that number when stating their power. Only the uninformed refer to their cars Flywheel hp and tq.
