Listen to this guy, people. He's a smart guy that is willing to share knowledge. That's a rarity in this industry, and yet another reason I have so much respect for Aaron. You're my boy blue!
Always enjoy your musings. Your dyno number is 416@ wheel hp dynojet? ecu calc tq and then hp is at crank? An indictment of high DJ wheels figures given this is awd?
Thank you :) For the numbers, you could look at it that way I suppose. DIN power ratings tend to be very close to DJ wheel horsepower numbers based on a wide assortment of European autos I have dyno'd. High or not you can't manipulate it like others. One mustang is 13% less, one 9% more, dynocom that's consistently 9%. I typically corelate HP to trap speed and leave the dyno battle to others. I can say percentage loss is NEVER static as some reason, nothing changes the friction unless it's an unlocked torque converter.
@@AaronONeal1 Agree on all points. Just an observation. I’ve been using a dyno dynamics at a couple of places lately. One place let’s the drive wheel ride up the front roller and it over reads and can mess consistency. Other place ties the car properly into both rollers and reads where I’d expect and super consistent. Many ways to mess with a run on dual rollers. DD use a fixed loss percentage to estimate flywheel. It’s rough as friction and drivetrain won’t be fixed, but it’s also not consistently measurable from what I’ve seen so it appears to be their compromise to those that want it. Just an elevated whp guess
