Hi,
Finally got the 3bar map sensor characterized to run closed loop up to 30 psi, no cel's. I'm running low torque tuning at low rpms, but max fueling at wot so the car is a nice daily driver. Spun 192hp/363ftlbs. Weather was pouring down rain. Regardless of std, sae, uncorrected, it's wicked fast. The first spin the wheels broke loose from the rollers and the motor went to 5000rpms instantly. They had to readjust the straps and add a couple more to hold this one steady.
Earlier run at 25psi was 182hp/368ftlbs but very smokey, with higher egts - 1150max post temp - cooler at 30psi.
The last run was the best hp at 30psi. We spun in 4th and lifted at 4000rpms. I noticed the 12mm hp drops off at lower rpm, probably with piston float. They are only rated at 1750rpm cuz of the added inertia (thats 3500 crank). Note: this was a bosch 12mm bought from Bosch in Germany, not a local NA sourced pump. Oh, and the boostvalve was set at 35psi, the poor little 1749vb couldn't surge if it wanted to. Smoke wasn't too bad but we were definantly gagging for O2.
