Did a run with my Dynolicious program from my iPhone and you tell me if its somewhat accurate. Stock RB25 @ 7psi. On stock size tires and worn out VLSD.

Sounds about right for untuned on street tires and not so great of a run. I'll bet on a prepped track you could knock half a second off that.

I was just playing around with the App just to see if its somewhat accurate. Im pretty suprised. I think the car has a little more power in it too cause i have an exhaust leak at the turbo right now that needs fixed.

Yup. You type in your vehicle weight and drivetrain loss % (0 is whp according to the program) and it works off the accelerometer or G force sensors in the phone. Very similar to G Tech meter but simpler.

My techie coworker sent me a link to that app last week. I don't have an iphone but that would be very cool to mess with.

Those numbers appear accurate. I ran almost that exact same time and trap and an even worse 60' time , but I was running 12 psi with 8.5:1 CR. Otherwise it sounds exactly the same.

What's the average drivetrain loss of these cars? 15%?
