Default Crank Pulley Size

Does anyone know what the diameter of the main crank pulley is on a 92 ssei? I'm sure Willwren knows.

I want to figure out the % rpm increase with the 2.3" pulley.

Thanks.

Stock on the 92/93, it'* a 2:1 ratio, or very close to it. Your SC with the 2.55" stock pulley is running at twice your engine rpm'* (or very close to it). That should make for simple math by using your redline rpm'*. I don't recall the stock diameter (used to know it). And don't ask me, cuz my redline is different than yours now.

With my raised redline, and the 2.25" pulley, my SC is spinning at 13,600 rpm'* at engine redline.

Where are you getting a 2.3" pulley?

Hmmmm.....he may have discontinued the 2.2". I suggested he drop the 2", as there isn't an intercooler available for our generation, but I didn't know he dropped the 2.2". I'll get ahold of him tonight and see what'* up. He can still make any custom size you want. His lathe is CNC, and I'm sure he still has the programs for the smaller pulley sizes, even if he doesn't have them listed on his website.

Brian is trying to get a better handle on the Series 1 application. He'* very well-versed in the Series 2, as he owns a GTP.

LOL
I thought maybe there was a willwren impersonator out there somewhere.

I am interested in keeping it modest anyways, so more likely to try the 2.3 or 2.4. It'* still more of an everyday to work and back sort of car for me.
