Would the readings be way skewed if you disconnected the haldex unit and ran it on a two wheel dyno? Any way to account for parasitic loss to the rear wheels?
Wondering because APTuning just called me and said they just got a new dyno.
i ran my car in both FWD mode adn AWD mode on a mustang dyno and found about a 5% difference in power at the wheels. you can use that as a rough conversion factor i guess
Just figure 15% drivetrain loss on a 2 wheel dyno. For an 4 wheel dyno it depends entirely on what type of dyno it is and how it loads the drivetrain. Can be anywhere from about 20-35% drivetrain loss.
Divide whatever wheel hp number they give you by .85.
crank hp = x wheel hp = y
x - .15x = y (1 - .15)x = y .85x = y x=y/.85
crank hp = (wheel hp)/.85
I don't care where you're from, where you vacation or where you have a summer house. I don't care who your favorite political candidate is, who your least favorite political candidate is or what your cause du jour is. I don't care about your kids, your pets or their accomplishments. I don't care what club you belong to or how you spend your weekends. All I care about is why I'm stuck behind you.
You must have been in the advanced class. I didn't see that level of algebra until the third year of my PhD program.
