lRight on! I know my big tires rob me blind of power but it helps give me the ground clearance I need. I will upload pics of my truck on Monday. My truck has a 5" lift in front and 3" lift in back w/ Bushwacker flares. Thus the bigger tires. I know a lot about what I have but little about what I think I want. LOL! How much for 4:10 gears? Where would I buy them? Are there any other mods I could do besides supercharging my engine? They are expensive and I need time to save.

Kinda left out the lift on the vehicle description.

88Racing, another moderator here, recommends Randy's Ring and Pinion. Give them a call and they'll probably be able to set you up. I've never had to deal with any shop for my truck so I dont know what it costs to have gears swapped out.
Randy's Ring & Pinion. The Differential Experts. Auto Parts & Services.

You could try looking for cams and other internal parts. Those have always shown improvements on gas engines.

Another form of boost that I'm actually considering (if it would just start raining money) is the squires turbo system. Might be worth looking into if you go off road a lot. Sometimes turbo lag can be a good thing out on the trail.

Thank you sooooo much! I truly appreciate your advice and opinion. Yeah, I forgot the lift description. It is kinda nice to have so many mode you forget about them. I will look into what you suggested. How much for that turbo?

The price varies but looks like it is about the same price as a supercharger. I could have sworn they were quite a bit cheaper...but I also looked at it over a year ago. Damn time flies! . You'll have to find a local dealer and ask them. Just look up STS, they have an F150 package and a dealer list.

I would look into new gears and maybe the e-fans and under drive pulleys. Much cheaper and they help a bit.

I've heard the sts system sucks up water, would creating some sort of cover help with this? I get concerned with a rear mount exhaust that cost 2 grand sucking up water and ruining my 42k truck just my 2 cents

Also look into 4.56 gears, more beneficial than going from 3.73-4.10

I personally haven't heard of that happening but you are definitely right. I would spend an extra $50 for some PVC pipe and run it into the engine bay or to any area that is higher up.

I must gotten a price for the twin turbo F150 kit.

hampsterzone - Since your engine is not being fueled by a carburetor, the throttle body spacer is better used as a doorstop. (Or perhaps you could get someone to buy it from you and put the cash toward new gears which WOULD provide a benefit.)
