Dyno operator ran both cars, we weren't even allowed in the garage, we're just at the edge filming. He was pretty lax on that rule, but I could tell he was going to be the one running all the dynos.
The 185 runs on 10psi he went off the dash tach. For the 12psi run, I told him to use tunerstudio's tach and run to 6900. Still doesn't look like he did.
They were also all in 3rd gear. I told him 4th, but he tried it and said something about it being a better match for the rollers in 3rd. Oh well.

Kinda sorta, wasn't ever going to complain at $25 for three pulls.
Would of loved to see 4th gear, 1500rpm start or less. I know it builds 10psi by about 2800, so starting at 2500 or where ever wasn't great. Oh well.

compared to mine:

for S&G's. At 3500RPM mine really ramps up and will shoot to all of it boost, I think this effect is due to the .48 a/r t3 turbine housing compared to the .86 a/r t25 of yours, where even though you have smaller wheels, the turbo still is a bit slow to wind up. Every SR20 T25 plot I've even seen does the same, even Lars's when you compare it to say Paul's 2560 or Soviet's EFR.
by fudged the numbers, I just mean I pulled the closest number I could determine by looking at the plots, without having the real raw data on hand; otherwise it's close.
