Testin out the 72mm @ 1/8 mile...15-17psi
Well after some smoking issues with this turbo, i'm running a .058 restictor now and all seems to be well so off to the track tonight.
Started at 17-18psi, 3700 launch. This track is usually bad, but to make things worse it was import night and they pretty much didn't prep the track AT ALL the whole night and the street tires made things worse. Track was horrible so turned it down to 15psi (wastegate pressure) and 3500 2step. This built 12psi at the line and was still wayyyy to much on the ice. Best I skated to was a couple 7.2@99 with a 1.7x 60's. Good news is I think with on a good track, 18-19, and 1.5x, I think shes got a 6.8x in her. Well see on another night, then I turn it loose on the 1/4.
Also it was who gives a *hit night, they let my g/f ride one pass lol. Ran a modded Camaro, he wanted to a two bulb hit, but I still got him.
Didn't break nothing, good times!

Nice runs, that thing really moves out nice!
On your second vid, take a look between the 30 second to 40 second mark. Look at the dirt (or whatever it is) that your front tires are laying down on the track. I'm wondering if that has a negative affect on your traction, and if front skinnies are something you should consider to help out with that.
