Im looking at buying one soon and I was wondering if they are all the same size and quality.

Thanks!

 

Hi

For an excellent quality supercharger pulley with unlimited advice and full warranty support you should strongly consider purchasing off Shardul on these forums.

His products are excellent and his advice is the best out there. He will answer any question you throw at him.

Thanks ozzyamg

 

werd... shardul is **** hes helped me countless time along with a few members here who i am thankful too

 

As far as I know - There are two types of pulleys for the supercharger.

One is that fits over the clutch and gives a boost of around 1-1.5~ increase.

Second gets rid of the clutch altogether and gives a huge bump in boost depending on which variation you would go with.

77mm, 80mm and 83mm . I do not remember exactly as to if there are more or less in this variation.

For the second option you need continuous IAT monitoring and a "perfect bang on tune". I use quotation because I am not entirely sure as to the specifics.

Hopefully someone will soon chime in elaborate further.

and yes Shardul is a very helpful member.

 

Hmm, I guess I need to do some searching. I was going to do a Belt Wrap Kit and new SC Pulley to gain some power, but really want to rid my car of that damn chirp! Any one option better then the other for that?

 

Im going with a clutch pulley. I just wanted to know if there is a difference between the vendors who sell them.

 

Clutch pulley is -under general consensus the "safe pulley" .

Clutchless pulley gives a "lot more power" put comes with a caveat - continuous monitoring of IAT's. It gets rid of your S/C engagement that happens in the

car. You know how -you step on the gas pedal- S/C engages and then blast off ? - This pulley you step on the gas pedal and you are off to the sky. Some

have mentioned it's downright scary in a good way(cuz one isn't used to that sort of response from a Benz lol).

Message Denroll or Bramage - they both have the pulley and are facing some issues too but they are so happy with it that they are overlooking those lol

 

clutched pulley and BWK are the way to go... and Shardul is def the man to buy them from

 

Pulley is ordered from Shardul. Tune coming up on the 20

 

Sorry, not wanting to open a new thread, What is the general opinion about going with a SC pulley or a crank pulley???

To be honest I never considered the crank pulley. What are the cons to it ? Is the water pump or alternator under runed ?

Im looking for some opinions.

Thanks

 

Hi

First I would consider doing the smaller supercharger clutched pulley and leave the crank pulley standard. Just by making this very easy change with a tune will give you a very good gain. In fact I have been very happy with just this increase in boost for over 12 months.

It is only now that my car is not my daily driver that I have also opted to fit a 172mm crank pulley to work in conjunction with my smaller clutched supercharger pulley. Remember the bigger the crank pulley the more load on your motor and the smaller and lighter the supercharger clutched pulley the less load on your supercharger. So from a pure reliability issue the smaller clutched supercharger pulley should always be your first way of looking for more boost and only then should you consider changing your crank pulley for more boost as you will also need to fit a different water pump pulley to fit the larger crank pulley.

As I know. Crank pulley will generate more heat and will require to have bigger injectors and fuel rail to be safe.

I guess you should consider headers, IC pump and H/E .

Good luck

 

From what I have read, crank pullies have more of a chance of developing issues.

 

So I recently bought a e55. As far as I know It has a 180mm crank pulley a stock SC pulley with secondary cats and resonator deleted and a euro charged tune. Everything else is factory....should I be worried about putting too much load on the motor and possibly going lean bc of factory injectors and rials and blowing this thing up?.? And if I'm not mistaken the euro charged tune brings the rev limiter to 6700rpm. Which with the larger crank pulley it's probably putting ALOT of stress on the motor in the high RPMs.??...... Somebody please chime in with knowledge and advice.

 

You need cooling mods STAT if you don't have them already. Many great threads to get you started here.

 

If you have a 180mm crank pulley I'd assume that the owner installed a bigger
H/E as well? If not do it asap.

My first mod was bigger H/E then the S/C pulley.

 

Viren...what H/E did you go with and what is bolt on or did you have to do modifications?

 

I think the general concensus is headers, tune, cooling mods, fuel, pulleys.

Just by changing the headers and tuning it you'll pick up a good bump, keep it super consistent and reliable. I have a 180 crank with cooling mods and a eurocharge tune and I'm still running super hot air charges which yank timing and richen the fuel trims (effectively reducing power).

**** by the time I get to 120 the ecu is pulling so much off the tune I'm Probly similar in power to a a header/tune car anyway.

Fortunately headers are in the mail but yeah. If you only wanted to spend a few bucks $1000 for kleemans and $500 for the tune (which through a lot of these shops they will make courtesy adjustments as you add more parts) you're up 50 or so hp with a damn reliable car.
