sensible mods

[daveyburt]

Hi Everyone...

So, after a couple weeks in my (new to me) 01 7.3, I think I'd like to have the power be able to pull into traffic a bit better, and have a bit more grunt on those long highway hills, without decking it. It goes ok when i punch it -I just don't like hammering down on it frequently.

I'm new to diesels and their mods. I'm wondering if there are any tricks to getting a bit more power without requiring an exhaust. I see doing an intake as pointless unless the exhaust is there. -just me, might be wrong...

I'm not looking for big power, just a nice little boost over bone stock.

I might consider a muffler delete but would rather not.

Thanks!!

well to get more power without a tuner you are going to need to change some of the stuff you dont want too ......i would say turbo back exhaust and a intake let it breath and flow better

You could do a 5.6k mod.
It increases oil pressure to the injectors.
Basically a "poor mans" chip
Someone did some tests with it on the dyno and it came out to around a 50 hp gain
I had one but took it out due to the sloppy shifts

It would be a bad idea to do any power mods without a muffler delete and a pyrometer.

Sorry to hijack this but saw you mention it so figured I would ask. Stock Muffler delete is it worth it? Saw the pipe to do it at a place online plus I got plenty to make my own and I have a bender so it wouldn't really matter. But is it worth it. Because isn't stock what 3.5 and what else are you getting rid and improving on by doing a turbo back exhaust?

Definitly worth it. The muffler puts more restriction on the exhaust, which is really bad. It won't flow as good as a 4", but thats what i have on mine and it works good. It still will flow a hell of a lot better without that muffler. And you wont peg a pyrometer as fast.

You don't need a 4" exhaust, the restriction is in the factory muffler not the size of the plumbing. The factory muffler takes a 3.5" exhaust and necks it down to 2.5", backpressure is essential for a gasser but the opposite is true for a diesel. You can straight pipe it or for about the same $ you can do the Walker BTM muffler which is 3.5" straight through and will flow all the air your truck needs for what you are going to do with it. You need to get more air in as well, you can use a Ford AIS intake ( nothing will filter better) it looks stock and is quite, or you can do the DIY Tymar intake for $60, as with all open element filters they are loud, take your pic on intake. Then you want to support the weak link in the powertrain, this being the trans, install a Valvebody from FTVB, JW or BTS, take your pic, of course the very first mod should always be gauges, this will give you a solid baseline of how the truck performs so you can easily see how all future mods affect your powertrain. After all these you can then safetly add some more ponies, the only two I would consider is DP or TW. You can look at my mods in my sig to see what I have used. My truck works less to do the same work it did in stock formation, as long as I don't abuse the extra power ( very hard at times) the truck should have a longer service life.
PM me with any ?

Thanks everyone!

Hornet: You've given me plenty of things to look into, sounds perfect for now. Thanks for the heads up on the tranny. If it's worth doing, it's worth doing right.

The rig is at the shop getting $1k worth of tires. Research is all i can afford at this moment.


I may be PMing you in the future.....thanks!!!

Davey: NCHORNET has alot of good info, and won't steer ya wrong...

Aside from toasting the trans, that happend to me first... had a local fella rebuild it, did a fine job for about $1400 with some goodies, and no problems so far, but after that, I spent my next approx $800 on gauges and pod ($330 kit from summet) DIY airfilter mod ($50) removed the stock muffler, and replaced with 3.5" pipe, did it myself, so it was free, and a DP tuner ($420) and wow what a huge diffrence. Even with out the tuner, it ran a lot better.

Good luck...

why dont you just do a 18k or custom tuning would be better,intake,and a cat delete.and call it good.
