...............you are still missing the point. How did your friend increase his boost? He did it by devine intervention? Or he changed a pulley? You increase boost by using a larger crank pulley and/or a smaller s/c pulley. When your friend went back to the stock pulley (decrease boost), his belt shredding problem went away. Mmmmmmmmmm, I wonder why.
..........More importantly, even if you are right that the mere addition of boost causes the belts to spontaneously disintigrate on their own. Belt problem is still the least of the problems when increasing boost in a Kleemann V8K. As Blackbenz has righly pointed out, the main problem is in proper fueling to prevent the car from running too lean with the increased boost. How did your friend fuel his S8 with the 11PSI of boost? What were is A/F ratios?

.............thanks. I decided to sleeve the cylinders partially for cylinde wall protection and partially to be able to run aftermarket low compression pistons. The cylinder walls in Mercedes engines including the AMG ones are amazingly thin. The engines were built no to be repaired or re-used.
