I took my supercharged 190E 2.3-16 to VIR last weekend. The SLK supercharger and SDS engine management system had been installed and working well for six months of daily driving and I was ready to put it to the test. Pictures After 5-6 laps of the VIR North course, it started pinging, the temperature rose to about 135oC. I pitted for the session, backed off the ignition 2 degrees, topped off the water and wired the auxiliary fan ON. Two more laps and the symptoms reoccurred and now I noticed significant blow by. I called it quits. Driving home the next day at a constant 60 MPH, I noticed the oil pressure begin to flicker at 3000 RPM. About two miles short of our relatives farm near Richmond, the engine totally failed with a clanking noise. The car is still at the farm; I borrowed a spare car for the trip home to Virginia Beach. I didn't have time to do any diagnostic work as I figured that the engine would need to be torn down anyway.

I'll keep you posted as things progress.
