i am giving the pully prop's. I didnt thing it would be that mutch of a diffrence if at all. i used to get about 210 miles a tank and now i am getting about 250-260 a tank + power! I cant wait to get the E-Fan.

 

I did it the other way David. I got the e-fan first. The stock fan drags the life from the engine with the stock pulley. For me the pulley gave me as much as the e-fan. I think the pulley is more effective; but I stole it's thunder by getting the fan first. bob
