i dont know if you will feel that much without the tuner and other mods. i added a 2.8 upper pulley and a 4lb bottom with the predator and cold air intake along with free flowing exhaust and watch out, that puppy moves out now..

You could even run a 2.76 upper, with a 2-4-or if you have the guts, 6lb lower. Like dirty diesel said, CAI, I don't have much experience with the predator, but it seems to be good, with a free-er flowing exhaust will make an awesome combo. Don't forget to have it dyno'd to make sure the a/f ratio is ok. Would suck to have the pred. off just a little.

The upper pulley on the eaton is pressed on and from what ive heard a pita to replace whereas the crank pulley is realitively easier. Just remember it you do change the pulley be sure you have a predator programer or a chip, otherwise your in for a harvard lesson. Still waiting (hopefully buy x-mas i can give myself an excuse) to get and interchangeable 4-6 crank pully and a predator programer(which has a built in datalogger .)

Harleyss02,
I have a stock (2.93) upper pulley off a 2001 Lightning that will fit your truck. Installing it will put you at 8+ lbs of boost and will add about 12 RWHP and 22 RWTQ. Click on my user name and send me an email if you're interested.

Lost Low End Torque Harley F150
Hello everyone. This is my first forum and I need some help here.I have a 2002 harley davidson f150 that we cut the cats off and put some superflow 40s on. now i"ve lost the low end torque.I have a cold air intake,4 pound underpulley new plenum w/ an accuefab singleblade throttlebody and a new flash tuner. So the question is how do I get the low end torque back in it and what would be considered safe to bump the boost up to.I plan on changing the snout pulley to a stock lightning pulley which I believe w/the 4 pound underpulley would give me a total of 4 pounds.
