How many of you actually daily drive with a smaller supercharger pulley?

Ls1toAMG

A lot of people drive with them everyday. I got mine a month ago and it is a better daily driver than before. Throttle response is awesome.

I had the smaller pulley on the C32 for some years, was the only car I had.. I have had the 84mm smaller pulley on my CLS55 for about a year and half and now just installed the 77mm pulley. Car runs great.

Is consensus to now use smaller SC pulleys instead of larger diameter crank pulleys?

WillyG

From what i have read, yes. But then you hear those horror stories of them breaking off and wrecking havoc. Do they typically shear off because they're not properly installed?

I basically DD my CL. Was on an 84mm clutched now on a 80mm Fixed. I do not run the resistor tho.

I daily mine, first with the 80mm FSP and now a 77mm FSP.

I've been running mine daily with a 77mm clutched pulley for maybe around 8 or 9 months now, no issues.....just make sure cooling is top priority, summer can be a killer

WillyG

I have the S class so the bigger h/e is not a top priority. Although I'll be doing the ic pump soon. With all these stories of the broken pulleys, is it really just a bad batch of them? Or is it the installation?

the design was updated a couple times. there really hasn't been a higher than usual failure rate since. even the stock pulley is known to let loose, so i'd recommend getting a pulley shield from latemodel21

I daily drive mine with the 77mm fixed pulley. I'm going to assume that I put more miles than most members as I drive my car for work as well and I love having the fixed pulley on there... the throttle response is so nice to have. I went with the fixed pulley originally though because I didnt want to deal with the clutched pulleys exploding. For reference I've put 30k miles on my car in the year that I've owned it.

Here is my Shield

77mm fixed on a daily? Hmm interesting, how long have you had this setup going for?

WillyG

I'll have to contact him, does he still have them in stock?

romeomikehotel

Yea it's definitely a fun daily. I've had the fixed pulley on for around 7-8 months I believe. I'm running the 77mm and two auxiliary heat exchangers. Otherwise its stock.

latemodel21

Yes, in stock.
easiest way to get one is to PM me your email address and I will reply with some info.

Cheers,
