hi everybody,
I saw these on the jegs performance website and its claimed they will give 10-15 extra hp. its a set of aluminium pulleys and they noly cost around $130. So $130 for 10-15 extra hp, sounds too good to be true. i was wondering, do they really work??? heres the link to the pulleys in question:

thanks.

 

Some will tell you yes and other will tell you no, I havent got them on my setup, I'd say maybe they'll free up 5hp...

 

I put a BBK crank pulley on my 1994 Z28 before I sold it & I didn't notice any notable gain. I'd say for $75 do it anyway. All those 2-3 HP mods add up after awhile, Fred

 

I had them on my Mustang but I dont have them on my Camaro I never noticed anything with them but the cost.

 

From what I've read, it doesn't seem to work:

Thanks for the great feedback everyone. I really appreciate it. Well I posted this in another forum too and the majority also said that theres no real obvious gain, so I'm gonna stick with my stock for now coz i can get a lot better things for that price in my country. Thanks for helpin out anyway.
