Hello to all,

I would like for you to post your thoughts on HP gain and Torque gain on a (2X4) 5.4, 4.10's, K&N GII, true dual exhaust with no cats, X-pipe and running open dumps, 76mm TB, Mass Airflow, electric fans, pac chips, (code BJO2) 1"Helx ( I know I know, only gain when towing) and running on good 93 octane....I know this is a lot of crap to read, however if anyone wants to post I want to read it.....hell even 1/4 mile times with mods or without....and hope everyone has a Merry Christmas...

Flowmaster Y, K&N FIPK, cat back system, headers and chip each made a noticeable difference in my truck, in one way or another. All inclusive my driveability while towing is a LOT better than stock. I'm not into go-fast stuff... I just wanted to make towing easier and more efficient since I do tow a lot.

Headers gave me about a 1mpg measurable improvement in gas mileage but was expensive to buy and a PITA to install. I didn't notice anything on the power side of the deal either. I don't think I wasted my money but I would not put this first on the list.

The Helix/throttlebody spacer/poweraid or whatever brand spacer is a total waste of money. If anything, all it did was make a goofy sucking noise when you accelerate... Mine is now a paperweight on my desk.

MAS upgrade gave a little better throttle response but no noticeable increase in torque, fuel mileage, etc... It was probably a waste of money but at least it didn't create a stupid sucking noise...

The first mods to look at are: superchip or JET chip, K&N or Airaid or other airbox mod, flowmaster y-pipe and cat-back system...

I don't have numbers but these mods are worth while, especially if you tow. I'm currently looking into the electric fan replacement since it's looking like there's a measurable increase in mileage and power. It's also looking like that's not going to cost a lot either. Probably going to do that in the Spring...

 

ronhop,

I noticed about 1.5 mpg gain when I installed my electric fan, as far as HP and Torque gains, I noticed no HP gain, but less drag when towing on the highway...I like it...

What is the make, cost, and where did you get your electric fan?

 

BruceScrew,

To tell you the truth I have had this fan for over three years, it was on my bronco.....and I dont remember how much that one was.....I think that Flex-a-lite has a web page and eveuently I want to get rid of my 18" and get 2- 14"s......but for winter it cools just fine but before the Texas summer hits I will need to upgrade, especially towing all of the time.....and if you want to look at JC Whitney .com they have some and that is where I purchased the 18"......

I've read from several of you guys that and electric fan is a good thing. Makes all the sense in the world to me. Neal sent me some info on what he's been doing as well with 2 16" fans and adjustable thermal sensor. I may very well go with his set-up when he gets it put together. He's quoting around $330 for the whole deal. I also contacted Flex-a-Lite about their offering...

Below is an email I got from Flex-a-Lite on applications for late model F150s... I asked what they had that was application specific since their WEB site had no applications for the late model F150s with either a 4.6 or 5.4 and here's their response. Read from the bottom up...


We are looking at about 6 weeks before we will have these shipping...
