Dyno day!

Well went to a dyno today! It's a dyno junk lol but it works for a rough estimate of power. There was no rolling calibration done or anything on any car the entire day. Strap down and go. Most dyno event and dynos I have seen make you roll the wheels a little and get the rpm and speeds matched up and ratio dialed in first. Anyway made 515/483 in 97* heat 45% humidity. Only saw 11psi due to heat and maybe a little belt slip I'm there not sure. All in all was happy to see what it did. Does anyone know the parasitic loss of the 545rfe trans?


Final pull Beccas view see how guages on screen don't track to good even rpm was off!


Buddy's view here watch the tire wrinkle up. Was told to go to a 3.22" pulley and that will be about max for my fuel pump and setup which I planned already to do.

Very impressive! The 545rfe has a high parasitic loss. I remember being surprised, but don't remember what it was. ...

I just did a Google and it goes from 26% to 15% to it can't be calculated. So take a guess..
