Crankshaft Pulley Question
With Victor's very kind assistance I purchased a new SLR crankshaft pulley, planning to upgrade the stock pulley on my SL55.
Interestingly, both the SLR pulley and the (supposedly) stock pulley on my car have a 6 3/16" diameter across the outside lip.
I'm thinking that the stock pulley on the W211 55K engine measures 5 3/4" across the outside lip. I'm hoping that one of you good folks either knows the measurement or can quickly measure your stock pulley diameter.
Thanks!

People need to do more research before they start assuming this and that, because it will cost alot of money or worse yet engine problems!
jmf, the SLR blower pulley is smaller, and adds boost through the blower pulley instead of the crank pulley. Your best bet is just stick with a tuners pulley, as they are engineered to work with our combo. Unless you know SLR stuff inside out, it's best that people not try to Frankenstein there cars. Stick with a Kleemann pulley with Kleemann tune, or Renntech with Renntech, alot less problems, that way you got piece of mind also with an expensive car.

I disagree (as usual lately). If you think getting the RunnTech pulley is safe, ok. Using SLR parts (IC, etc.) is no different than trying tuner stuff. You are taking a risk in either case. Do your research and enjoy.
As for the other question. I do not know. I think I can find out exactly what the diameters are, though. I would hope that someone can answer more quickly, though.

Thanks for all the responses. It's a good group of folks here.
In retrospect I was too quick to pull the trigger. I'm pretty much wired that way temperamentally which is sometimes helpful, other times not so much.
Yes, Jakpro1, it was a special order so no returns. On the positive side, I now have the world's most precisely machined door stop. It wasn't all that expensive, either, so I have no profound regrets or worries about making this month's mortgage payment.

LOL!! We are all whacked in some way or another. Keep up the positive attitude and something will come of it (as you say).
