Anyone have these? On my previous non-pcars they work great, and add some free horsepower.

I saw a guy on the classifieds selling them made from billet, claiming dyno proven 7 rwhp gains.

their was a recent GB on pulleys..... and yes, their are supposed to be HP gains. The ones in the Rennlist classifieds are the Broadfoot/Autosport Racing Pulleys. I'm actually going to go look at them in person today.

Let me know what you think...I'll look on the web for a Canadian version if possible.

Underdriving pulleys will not give the power gains claimed on the 944. Maybe even 2 HP at the most, which CANNOT be felt.

Correction; different pulleys do not make more horsepower, only free up one or 2 to go to the rear wheels. Same idea that applies to removing your A/C compressor; it's about 5 or 6 HP that isn't spinning off the front of the engine and is instead going to the transmission.

broadfoot sets are being sold on eBay for ~$300 (black or blue color)

they are pretty decent quality and work well
