With the pulleys I have read that they reduce the rotating mass which will mean around ~10whp.
Any insight into this?

Unorthodox pulleys or greddy

AAP Dual fans

Aftermarket pullies could provide a small hp gain (eg. 5hp - 10hp). This is most critical on engines that can't produce a lot of power to begin with (eg. Honda ), or if you're going for a particular configuration (eg. BPU+++++ - trying to max output of the oem twins).

Then AAP fans look great and give you more space in the engine bay. They also allow you to see the expensive, shiny aftermarket pullies you put in. However, they do not outperform the oem clutch fan - especially when roadracing in hot weather.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
