Just stay with the 2.87.

Agreed. I am also curious about the source of the 2.75 one. SOHO may sell the (2.75) pulley/belt combo but it is barely needed to have a smaller one like that if you stay with V-3. The 3.47/3.0/2.87 will get you way out of its compressor efficiency. I did ask my friend to customize a 2.8 serpentine side jackshaft pulley for me just in case, though!
CupcakeZ you can PM me if you still want a smaller one like mine (custom 2.8). I may never have chance to actually use it. https://www.instagram.com/p/BodgmfsAxNz/ https://www.instagram.com/p/BoL6rtknN9f/

I might try a 3.6" Jackshaft SC and a 2.8" direct SC pulley

Should you use 3.6/2.8 supercharger side combo paired with my custom 2.8 serpentine side jackshaft pulley you will overspin your head unit to about 71500 RPM. This is highly likely to get you up to 20ish psi.. Are you sure you want to do this?

I believe he want's to use your custom 2.8 for the sc side but still use the 9lb (2.87) on the serpentine side. He'd still see close to 70000 rpm.

The number of rib is different for the pulleys at different sides. I haven't tried putting mine on the supercharger side. I doubt the 8-rib SC belt can fit it.

It asks for number of teeth You guys ignore this and just put diameter anyways or? Cuz we dont have teeth on the pulleys we use, we have ribs, right? And typical 8 rib pulleys on both sc belt side and serp belt side? Or im wrong?
