Underdrive pullies(Whats involved)

Installed on a stock 5.0 they gave a solid 15 HP gain. Yes, you would notice that much of a gain. I don't know how much of a gain you would see on our trucks but I noticed a small gain just from efans.

 

I am still debating on the UDPs but on the E-fans i noticed a huge difference in mid to top end a little in the bottom end but my heavy 10ply 33s and 3.55s are whats killing my bottom end but soon I will be having 4.10s put in

 

Where did you get your fans from? And why the hell are you running 10-plys???? That's got to be a stiff ride

 

Nittos are all 10plys for there truck tires well non street at least

I got my Fans from another forum member for 275 but they are the Troyer ones

 

If you can build a shroud, dual intrepid fans will keep your truck cool. Our trucks have a 32 in wide radiator so 2 16in fans would be perfect. intrepid fans are 14 in fans and need a shroud.

 

here is a picture of my setup

 

Nice set up.Thats a rout i may go with my fan shrowd.

I will be getting my underdrive pulleys from bbk and then also upgrading to a higher output alternator and yellow top optima batery.Afterall i also do run allot of aftermarket lights on my truck ans i am only adding more lights,lol.

Will keep ppl updated when i tackle this project
