More power

I have a 97 F-250 7.3L power stroke automatic trans with 80000 miles on it. I am wanting to get some more power out of it. I was wondering about new style air intake and also thought about getting one of the hyper chip of something that is good for my power stroke to change the performance. Not wanting to spend to much say around five hundred or so. Any info would help.

is your exhaust still stock? putting a new dp in and new exhaust will improve hp alot and lower egts too. u could do a napa 6636 conversion air intake, its cheap and effective

Well the thing is you can slap a chip in it for under $500 and make a very significant increase in power. However it's not a very safe increase in power. To do it right you need to add gauges so you can monitor at least your exhaust gas temps and if you have an auto tranny so that you can watch the tranny fluid temps as well. For a Pyro, trans temp and boost gauge you are probably looking at around $300-$350 just for the gauges and a pod. None of which adds power.

To open up the intake is a good idea. You can go the cheap route and DIY it for under $100 or you can buy one of the nice kits with the air dam and reuseable filter. Personally I like the AFE kits the best. They run between $200 and $300 last I recall. This wont really give you much power either. But it's good ground work for later.

Then you can install a down pipe which is a really good thing because as mentioned the stocker is mashed flat between the engine and firewall. They run just over $100 depending on which one you get. At the same time you can get rid of the catyltec converter which is another restriction. The rest of the exhaust is 3.5" throuout and the muffler is actually straight through so it's pretty free flowing but you can go to a full 4" system if you like. This will help the turbo spool quicker and will make it feel pepier but it really doesn't add much power. To do the entire system you're looking from around $250ish for to $450ish for a nice stainless steel system.

All of the above is stuff that you need for air management to help keep your exhaust gas temps down and give the engine as much air as it can take. Then you can start adding fuel to make power with the chip.

All said and done you're probably going to be looking at twice what you said you wanted to spend but it will be much more reliable and useable power. The chips do give a very significan increase in power. It's about the equivalant of adding a turbo to a N/A gas engine. You'll think you got a whole new truck. But then watch out because if the power bug bites you'll be looking to get more and start adding bigger injectors which will give about 4 times more power increase than the chip did by itself!

on my intake i bought a rechargable K&N filter with a 4inch flange ($55) and a piece of 4inch pipe ($6). I just took the stock box all the way out and clamped the pipe into the stock intake hose and the filter onto the pipe. works good for me and sounds good too. some people have negative thoughts on K&N filters but i have had one on my truck for 175,000 miles and have been very happy with it.

I just bought a new set of glow shift gauges with pillar pod for my 95 off of ebay for $200.00 new. down pipe replacement is a must. stock = crap.
gut the cat, dont remove it unless you want to put it back on soon . I got a very nice ticket by a state trooper for not having a cat or muffler should have known. they have been tellin us at diesel performance school that 2010 is going to be when the crack down on straight pipes and missing cats. but they are already doin it here. good luck and give it hell.

How did your pillar fit? Mine looks like *** when you open the door, you can see the stock pillar because they cut the plastic on the triple pillar to close. I fixed it so it looks alot better when you open they door. Also replaced the guages with autometer, wanted more accurate read outs, instead of a pyro that goes to 2600 and a boost that goes to 60.

Depending on you budget an intake, exhaust, and chip are the easiest ways to increase powe Intake is cheapest doing the NAPA mod. Exhaust is going to be more expensive. Unhooking the wastegate mod is free and easy. If you wanted you could do the 10K mod to save money ( It's like a dollar) and is like a chip without spending the money, but I dont know if it is really worth it because it could hurt your ICP sensor but some say it dosen't.

500 is not much at all to do it right...

your gonna want gauges first... then do the DIY intake and get a new Downpipe and staright pipe your stock exhaust...

then get a custom tuned Chip... even that will be over what you want to spend...

plan to spend 1k and you can do all of that and have a great safe reliable truck with plenty of power....

let me know if you have any questions

-Raul
