@ RIPP weren't you also doing RWD dyno figures? I'm sure the first lot of vids I saw were RWD only as per below. And just how did you disengage the front wheels?
We did simple math with ours - coming us with a 27% drive train loss off the Jeep advertised crank HP. We feel it keeps things honest showing it like we do, that way the clients expectations are set. The problem is clients think their car has 4XX HP at the wheels stock. Then they see our number and think, thats it... But if you do the simple math we're at 750HP crank -/+. But like you said, an engine dyno would clear the guess work.
The very early ones we were and then we were able to successfully test at all 4 wheels. The early Diablo trinity would put it in RWD shutting the traction off, then when we switched to the inTune it would not. Then it was just a matter of getting the loads right on our dyno and we never looked back. We agree, it's much more fun to see it at all 4 wheels for us and our clients.
