TT Dyno FTW! LMAO

Disclaimer....if I put the driveline loss at 15% it reads closer to what it should be, 516/501. That being said, the last time I tried to match up TT Dyno to an actual Dyno, I had to put the loss at 30%.

From the weather channel.

Phil, I was there. Laugh. I know what the temp was and the humidity. My point is, TT Dyno is too easily manipulated and is kinda like an accountant that says 2+2= whatever you want it to be.

RE: MY CAR IS A MONSTER!!!
I just noticed that you were tweaking with the drivetrain loss. Isn't that just a correction factor to get crank HP&TQ? I always used zero to simulate RWHP.

Also, I believe the frontal area is around 25.3 ft^2. This should actually increase the calculated power, but it would probably be close to what you're running at the wheels if you use a 0% loss.

I'm using what the TT Dyno guru suggested a few years ago. 0% loss and changing the frontal area and I'm just over 420/400. I have a much harder time believing that.

RE: MY CAR IS A MONSTER!!!
I figured it would be around 438hp/426tq at 0% before increasing the frontal area. And though that may still seem low, the newer revision has a "drive ratio comp" box you can check if the run wasn't done in a 1:1 gear. This will also raise the estimated HP&TQ up a little.

Either way, if you can get it to read consistently, it can probably be pretty useful. Staying at the same/similar weight and using the same flat-piece of road is probably the most important thing.

I have found it to be pretty consistent. Here's a comparison of two runs on the same road within a few minutes of each other.

It can be as consistent as it wants, my point is and has been it really means nothing. It relates to nothing, like all dynos. It can show where the power is, but beyond that everything else is dubious. IMO
