EFR comparison 8374 vs 7670
I have several boost logs.
I'm going to be compiling a LOT of data on the 7670 to compare with the 8374 when I finally make the switch next year or so.
All of my dyno testing will be done on a Dynapack and I'll have a nicely compiled T90 Transient response data represented graphically... as well as turbospeed data to boot.
THe car is down for alternator issues... hopefully it's back up next week and on the dyno that following weekend for more tweaking.

I have boost logs, but they're in kpa and I think the dynocharts show boost on them IIRC. My turbospeed sensor was not working yet because I needed a divider for the Digital Signal.
I need to post some data up here.
8374 on same 2.2L but with S2 camshafts on 270kpa of boost is doing 540awhp corrected/560awhp uncorrected on E85
peak torque right at 4k. Spins 1st and 2nd... its awesome.

your sig shows you made the same power on the 7670. typo, or care to elaborate?

For those who don't have a calculator handy, that's ~25 psi of boost.Any wheel speed data yet?
My guess is that you'll end up pretty close to Martin's Evo - 750 whp on kill mode, literally for his turbo. I suspect safe max power for this turbo is right at 700 whp or maybe a skosh less.
270kpa boost is 39psi! Actually really high for only mid 500whp, was it meant to be 270kpa pressure (ie, ~170kpa boost)?
