OM603 semi-super pump testing, fitted with Bosch 6.0mm elements
First post has been updated with 0-60 data. Note that all testing is done at 2400' elevation, the car would launch quicker at sea level. Also, as mentioned in the second paragraph of the first post, the maxed-out stock IP and hybrid IP were tested with larger brakes and LSD installed, and the weight penalty is making it look like the mods didn't provide as much gain as they should. They dyno graphs will all be with the big brakes and LSD so it will be a more fair comparison.
BTW, photos of the weird KKK wastegate are on my website at this link:

I'm still trying to wrap my head around why boost wouldn't build when I adjusted the setscrew in 1 turn too far. I'd have thought that if the wastegate was stuck closed, it would build boost (off idle) just as fast, not slower. ?????
