Im Looking for more mods to increase HP and torque for my truck and at the same time not burn holes in my pockets. Any suggestions? Has anyone installed any Aftermarket ignitions, Electric fans, Heads or pullies to a 2001 supercrew Harley. Im only running a superchip flip chip and air force one intake at the time being. Im also looking at supercharging in the future. What do you recommend? Type? Make?
Thanks,
Doug

 

I'm not sure what head are out there for the 5.4 but if you are thinking of heads, you may as well get the SC.

I think the stock fan works well and would doubt the cost of an aftermarket fan would be worth any HP gains you may get.

As far as pulleys, March always has a nice selection, however, if you are going to be running a lot through the electrical system (stereo), you may want to stick with the stock pulleys as aftermarket pulleys are bigger to not toll the engine (thus yielding more horsepower).

I highly recommend Jacobs Electronics ignition kits as I ran one in my Mustang, better milage, more torque, more HP, made the RPM range linear (power did not fall of). Not sure they have something for the F150 yet, I'd check MSD also, they make a good product.

Good luck!
