HI!... MIKEBIKE : I installed twin 16 inch electric fans, ASP power pulleys and hedders all at the same time and went from 15.38E.T down to 14.53E.T, so they definetly help in freeing up H.P. I used the "HPP" (HOLESHOT PERFORMANCE PRODUCTS) electric fan kit and got my ASP power pulleys from the F-150 ONLINE STORE VIA ROGER LEMERE.

Neal,

You said that the pulleys, fans, and headers droped you around 8 tenths to the mid 14's. I also see that you have the 4.10's and am wondering at what point did you add the lower gears? That and how much did it help out at the track? And finally gas millage with them....if you did suffer, how much? I am going to order the fan and pulleys in the next months or so and already have headers on the way but was curious about the gears.

thanks
justin

 

HI!... POKEY : I ran a 16.01E.T bone stock. I then added the 4.10 gears, "HPP" intake system, true dual exhaust and dropped down to 15.38E.T.

As for the 4.10 gears, in the city they are kind of bad on the gas but on the highway, I can get about 735KMS on one 92 liter tank of gas going 125KPH at 2450RPM.

 

just curious to know if it is possible to find out how and where to get the the electric fans you have or when it would be possible to get them? thanks.

 

HI!... JUST RIGHT : You will be able to get the electric fan kit from "HPP" through MIKE T at performance products. The kits should be available to the public in about a month or so.
