I can't seem to find/figure out what the diameter of the CL-S high boost pulley for the CT supercharger is. I haven't had time to hook up my boost gauge...but I got a low reading on the dyno and I want to make sure I actually have the HBP.

Thanks!

wouldn't it be stock size in diameter?

 

The SC drive pulley is the same but the alternator pulley is different. Err I think that's how it works.

 

The stock pulley was steel and if I recall was 3" in diameter. The HBP was black annodized aluminum and if I recall was around 3.25" (on the SC drive part of the alternator pully)

 

Pretty much dead on except I think the HBP was 3.28"
So its => 2.83/3.00/3.28

Ones magnetic the other is not (HBP not magnetic )Someone a few years back had the same concern and rightfully so they thought they had the HBP but it was actually the stock 3.0" pulley.

 

Fuckin show off!

 

 

Just for the record. My HBP for the alternator is not Aluminum. It is steel like the standard pulley but now I am going to have to go check mine again. The pulley on the end of the blower jack shaft is black and aluminum.

 

You have the older version the relatively new ones were redesigned to be lighter and have a nicer appearance, although you can somewhat polish the steel pulley

The the blower shaft pulley is always black/aluminum, so o suprise there

 

hmm...now I need to look for a CL-S HBP now.

 

Be careful your getting closer to blowing up your 3.0 like I did about two years back.
