How many cars rate HP at the Crank? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Some companies underrate their cars. For example, the srt-4 was supposed to have 230 crank horsepower. It reality it has almost that much to the wheels. It being FWD also helps some with that.

How many cars are rated by the company at the crank? I feel it's kinda fraudulent.

All of them.

calling the rear seats as "seats" is more fraudulent than that

Acceleration dynos (chassis dynos, inertia dyno) are a relatively new item spawned by the availability of inexpensive computer power to do the spin-up calculations. What car manufacturer are you thinking of that lists the wheel HP?

Get a R-Type sticker and your HP will be back to 200.

FWIW I made 176 whp with just a CBE on a dynojet (runfiles 1&2).

Edmunds made 173 whp stock on a dynojet as well.

I remember DD Performance in Texas also made 175 whp stock on a dynojet after an ECU reset.

Not sure if it's common or not, but I know a few others have as well.

You're gonna get ripped a new one by the forum, every single production vehicle is like that an it's not fraudulent in any way and is still a proper representation of power. Only aftermarket "tuner" cars will probably boast Wheel horsepower ratings. Modern Rear wheel drive cars will lose 15-19 percent of the crank horsepower through there drive trains.

Are all those dynos with just a CBE? Also what kind of testing conditions and mileage on the vehicles?

- My car had a Perrin CBE. About 15,000 miles at the time and a bunch of track days under its belt. Was dyno'd in October, so probably 60F weather.

- Edmunds' car was stock. It was tested in April in southern CA, so probably ~75F.

- DD Performance's car was stock. They list the conditions on their dyno printout (72F, 10k miles)

OP is trolling.

This ain't real life.
