Again, why are you bragging about making 196 brake hp when a stock 2.0 VE makes 190 bhp, 20V: 200 bhp, and the tiny 1.6 N1 makes 200 bhp.
We wouldn't be talking ALLMTRB13 # if it was in brake/flywheel hp. Making 232 at the crank is no big deal. A lot of people have done it, but 232 whp for a 2.0 is a big achievement and hence the controversy.

let me know when a manufacture regularly quotes whp over bhp/ps
What exactly is your point? Are you trying to say since your #s are in bhp that they more accurate than whp?
I got news for you .They are not.
Think for one moment. You did not dyno your engine on an engine dyno. Your engine was not ran outside of the car. Instead, you drove up to some rollers, strapped down, and ran through the gears like everybody else here, and guess what? You were on a chassis dyno. The chassis dyno measures whp and wtrq. The chassis dyno spits out whp figures and to get brake hp figure it has to do some more rough calculation like driveline losses, wheel weight, tire weight, gear oil viscosity, and so on.

2 guys *or girls, same car, same age, same mods, same wheels and tuning. engines make 200bhp +/- 5bhp on the same rolling road on the same day. one has 180whp and the other 170whp??? the 170whp had a sticking brake caliper is all. the following weekend this was sorted and the whp is now within a few hp of the other car. had they not done the runs together the figure of 170whp might have been accepted or opt'd for more tuning and more $$$ spent. stick in 50psi if you wanna win the whp cup.
imho whp can go jump compared to bhp/ps ie the power the engine is making regardless. yes bhp is a derivative of whp however the losses are taken into account.
You just shot yourself in the foot, contradicting your previous post. Stay in school.
