As the topic suggests, does anyone know of a supplier of a 14% SC pulley? besides jcw?

I have a 3% larger crank pulley, and want a SC pulley combo, without increasing SC rpm into that 19% range...

Suggestions anyone?

 

15% is your only option at this point. If you stay away from running at redline for extended periods of time the 15% with the 3% should do you just fine. Will probably want to get an ECU tune to really take advantage of it with larger injectors.

 

And I believe even the JCW is 14.6% -- so 15% is about as close as you're gonna get.

 

The JCW supercharger pulley diameter is 11% less than stock.

 

At least the one I personally measured was... guaranteed. Though I'm not 100% convinced that there aren't two variants... I think there could be... because other reliable sources have gotten the 14.x% number, supposedly by measuring. But I know for a fact that I used the calipers on one, and on a stock pulley, and did the math - and it was 10.x% (almost 11)...

 

Ok, thanks for the replies people.

The AUS dollar is almost dollar for dollar with the US, so it might be a good time for me to get some goodies sent over!!

I only wish i had have bought up now (with current ex rates), rather than in the last year, (i could have saved some $$)
