A turning point in Mercedes tuning...Performance Supercharger Pulley
This is what interest me the most! Please check thoroughly with any POSSIBLE belt slippage...or POSSIBLE shredding of the belt...
With the 185 crank pulley, the S/C spins to almost max at some gears.
Not sure if Brandon's actually released (i.e. posted) the Code3 S/C pulley's diameter, however... anyone who could measure one care to chime in, so we can "do the math" posted in post #8?
TIA!

My ODPS failure occured in 12/06.

since then.. I have fixed all the issues on the C32, except the seat modules and SRS light on my dash.
The E55 is running great. However my 2nd air pump went out again. So its back at the dealer today.
I have learned to live with the aches and pains of owning these cars and I have avoided paying major $$ by using local mechanics and buying my own parts (used or new). Also I have learned to research anything before making any clonclusions.
*quick udpate
My wife took the car to work yesterday. Upon her return, put the spot light on my belt once more. No signs of wear, no black powdery stuff, no signs of tear.
Wife just keep saying how the C32 is running great!
If I took your comment the wrong way sorry! And if I did just say so and don't make it bigger...
All he said was he's learned to do his research before making any conclusions on mods...

I wasn't sure which one you were talking about then and still don't know which pulley you are talking about now. 4 major pulley with the evosport kit are aluminum, crank, water pump, alternator, and power steering and only the 2 tensioner pulley has bearings in them. the 4 major pulley don't use bearings. the smaller tensioner pulley broke when the bearing fell apart on my car. no damage was done to the car and the belt wasn't even damage. the smaller tensioner was known to have problems btw.
maybe you were talking about the larger tensioner pulley and not the water pump pulley? just want to clear things up.

If you want pictures of the water pump cover I still have it.. just in case you have any doubts.
I also have emails to Evosport (conversations with Brad the owners son) and conversations with Vadim.
I think you are right it might be a tensioner pulley.

BUT I FEEL AS THOUGH THAT COMMENT WAS FORWARDED ELUSIVELY TO MEI learned from my mistakes and I learned to research my way of things I used to think were important.
Like plugs and wires, or exhaust system or learned to research that I don't need to pay $500 to tune up my car.
No where did I mention "research mods"..
My focus has been to get my cars back in working order.
One more day of use and one more day with nothing to report on the belt.
I pushed the car pretty hard today.. mostly street pulls from 0-80
nothing to report.
The reason I think the belt issue is important, is due to the fact my wife drives the car every other day... and I can have her loose power on the freeway or driving the kids.
So far.. belt looks normal.
I think sprintbooster only gives me better thorttle response especially off the line, while the SC pulley gives me tangible power. I had a couple of hard runs at 3 gear today and I believe the sc pulley along shaved at least a second or 2 off from 50-100mph. As for the dyno test, I guess brandon will take care of it.
btw, my 2-month-old belt is still in good shape. and I didn't have any belt slippage during the hard runs today.
