Header Help

[lilbuddy]

Hey all!
I am getting ready to purchase the torque monster headers for my 00' 5.0 and i was wondering if all of this work could be done with the engine still in its place. I kno for some SUV's the engine has to be removed. Thanks

There are MANY pictures, and write-ups here...and every single one of them show the install being done with the motor in place.

After you installed the TMH you said you were going to post results for the MPG.

EIther I missed it or you haven't posted yet

Engine in place, but lifted partially.

No, I haven’t gotten around to posting anything, I got another project started and forgot.

The problem I had was my fuel mileage was a little worse at first. I didn’t have the low end I expected. I changed my K&N cone filter back to my stock air box and filter and the mileage shot right up. I assume that I had too much air and too much exhaust, causing some kind of problem. I have gotten bigger tires since then, but I am now getting 20-21 MPG on the highway. Some of that is because of the effective gear ratio due to larger tires I’m guessing. But I do believe with the headers and a stock air box, possibly stock exhaust you can see some real MPG gains. Larger exhaust and intake helps power, but power takes fuel. The 5.0 has plenty of grunt with the headers and stock air box now. I would highly recommend them.

interesting. I would have thought easier breathing (which is the whole point of the headers) would have helped the mpg. I would think the proper exhaust would be needed with the right amount of backpressure, (especially for low end torque) but I guess I'm really surprised to hear about the intake.

Maybe if you were to put a venturi on the K&N you might get something better.

I'd like to try the TMH, but it just isn't in the budget any time soon.

I'd bet a chip programmed for the mods would help a lot too. I'll do that b4 I do the TMH.

Um the chip/tune should come after the headers, in fact on these 5.0L's with the factory manifolds choking your power the TM's should be the first thing you do.

Yeah, I need to get an xcaliber to fix that, but mine runs better with stock tuning and factory air box for the time being. Ive got to beg the wife for any new toys after the lift.

Your correct, exhaust back pressure is needed. After the headers my old dyno max had too much flow and noise, so I changed to a turbo muffler. And, my intake was a home made adaptor and a 3" K&N filter, not exact science. I guess on some things you get what you pay for.

I put on the TMH on my Mountaineer and still have plenty of low-end torque. That and gas mileage immediately shot up to over 20 MPG on the highway. My previous best was 17.9 and that was all downhill from Flagstaff to Phoenix.

Downshifting from 4th to 2nd is quite an experience, and results in a neck-snapping rush of power.

I did notice a slight loss in low-end power, but there is still plenty of torque on tap for work or play. I have a MAC intake, Flowmaster catback, and BamaChips programmer running the 91 octane performance (more top-end, less low-end) program, and it is still very torquey.


Side note: Anyone have any tips on how to tighten the rear engine mount nut? I was able to get the front one real tight, but the rear one is still loose. It hasn't caused me any problems, just for peace of mind I want to get it tight.

 

[tnmk]

Why should the TMH come b4 the bama chip? Isn't the the chip re-programmable for what ever mods you do or decide to change at any point in time?

 

[410Fortune]

because now you are chipping the truck twice = more $$$

 

[tnmk]

guess I thought once you had the chip you could change it at will

 

[wpurple]

I tightened the engine mount with a stubby open end wrench a gazillinth of an inch at a time :fire:

Installation of the TMH definatly opened up the Supercharger and my a/f readings look good, just need to change my MAF as it is pegging at 4200rpm

thought that the TMH would lean things out a little too much, but not the case.

 

[MountaineerGreen]

What I did to tighen my motor mount nut (after the install) is remove all of the bolts that hold the header to the block, lift the header and tighen the bolt with an open ended wrench. It took forever, just a 1/8th of a turn each time, but I finally got mine tight. PITA

 

[proftomda]

I agree with tightening the bolt with the header loose in the engine compartment. I simply useda a combination wreng and went very slowly but got it tight.
