Thanks. Looks like I'll be supercharging. And new fuel pump.

 

I don't have that kinda money!! I wish

 

A turbo is not tried and true like a blower is on the truck.

You don't need to upgrade the oil pump at stock boost levels, start increasing boost and turning out the RPMS and you'll probably need one. I have about 700hp on a fully stock internal engine. I feel I'm on the edge of what the stock oil pump can handle.

If your main goal is low end power you have four options:
1. Get lower gears, but won't completely eliminate the feel of power curve coming on after 2500rpm.
2.Get a stall converter. This only masks the feel of less power at lower rpm by allowing the engine to spin higher and the converter multiplying torque.
3. Change tunes. My first tunes where from 5*, and they were just OK. Noticeable improvement over stock, but nothing spectacular. MPT would probably be able to help, and at ~$70, it's not expensive to try out.
4. Blower. I now have a TVS blower and if you want that instant torque, right now at all rpms, then it's the only way to go. If you get a roush blower, get a custom tune because the tune that comes with the roush blower is GARBAGE. Drives like around town and you lose like 3-4 MPG. My tune from magnuson was MUCH better, but still needed improvement. Again, stay on the stock pulley and you will be fine, just change your oil more often and stay out of the boost as much as you can when the engine is cold.

 

This guy knows what he is talking about , If you have the $ to get it done .... do what he did and it sounds like you would be happy with the power ..... I could be wrong but he was one of the fastest F150s with 5.0 running the 1/4 mile ..... really fast truck especially for a 4wd supercrew w/ 33"s

 

If you look at the top of the 5.0 Quarter Mile Times and Mods thread, you'll see what these guys are running for power. I would like to see a Procharger or two on the list, but blowers seem to reign supreme as far as mods go.

EDIT** Here's the link to the thread on 5.0's in the quarter. https://www.f150forum.com/f70/5-0-qu...s-mods-190134/

 

My RC/SB came with 3.31 gears. I swapped that out and added 3.73 gears with a 5 star performance/tow tune and a cat back exhaust... I'll say what a difference!

 

A smaller TVS blower is going to be your best bet for what you are wanting to do. Nothing crazy or complicated, can be bolted on in your driveway in half a day. The smaller TVS blowers are not going to be as efficient as the twin screws such as Whipple and Kenne Bell, but with the larger twin screws, they need to be spun more to get going so the TVS is going to give you more of that off idle torque that you are looking for.

Turbos are going to be the absolute most efficient and give you the most torque, but are not necessary for what I think you are trying to accomplish. If you can read a turbos compressor map, one(or two) can be selected where you have no lag whatsoever. Lag is just a by-product of selecting the wrong compressor and/or turbine if low end is what you are looking for.

 

Fastest with a stock engine except for the #1 spot, but his truck is a single cab 2wd so mines much heavier. Oh, I don't have 33s on this truck.


Agreed. It would be hard to size turbo(s) to give you the torque you want and response that wouldn't choke the engine at the higher rpms, unless your pocket book is pretty deep, then anything is possible.

 

I was looking at the twin screw whipple. Do you think that would
Be too big? What size do you recommend?

 

Thanks for the link! I've never seen that before. I usually look at this forum through the app. I see I miss quite a few options.
