exhaust and air filter

[Toomstone]

do you feel a noticealbe difference in horsepower or acceleration when you put a k&n filter and an exhaust on your truck????

[BarryMac]

yes...
gjb

[Jordy]

Yep, and it got even better with the Attitude. ;)

[riverbound]

Yes. but to get the most you need to alter the programing of the computer, esepcially on diesels.

[Toomstone]

is there any good programmer or chip for f150 5.4 liter???

[Toomstone]

how much horsepower gain is possible with a gas engine with a chip/programmer.

[riverbound]

The hypertech power programmer seems to be the best out there for the gas trucks. I think it gives up to 30 hp. plus you can accomidate for larger wheels and tires.

[Toomstone]

wow there like $330 for 30 hp. that seems a little steep. does 30 hp make a big difference? im not a big engine guy as youve noticed:D

Dont waste your money.If you want performance,buy a diesel,Ford or Chevy.

Dude, $330 for 30 HP is a pretty good deal, figuring guys spend a couple of grand in head work for 70-100 HP gains. Your 5.4 is probably in the 250-270 HP range if stock, and that is being pretty generous, so yes, 30 HP would be pretty noticeable.

2001 ford f150 supercrew with the 5.4..... or a 2003 yukon denali with the 6.0

On a stock 5.3 you would gain about 13 more hp and 7lb of torque.
This was taken after a dyno.The more mods you have the more it will help.Dont know much on the ford trucks:)

[Toomstone]

will your hypertech fit on either of those??

[BowTie Rick]

Check out the current issue of Trucks magazine (issue 21). They do an independent intake kit comparison. In summary:
AEM 8.8 HP
Airaid 5.6 HP
K&N 11.5 HP
Volant -1.2 HP (yes negative)
AFE did not fit, could not test due to tube hitting fan blades (not just the shroud) Can you say oops.
Tests were done on a stock 99 Silverado 5.3L with 75K on it.

[riverbound]

I thought Volant and K&N were the same? I had one of the guys from Volant in here telling me they made alot of the K&N intakes for them.

Nope. They have a completely closed system; something the article talks about. Very nice looking but not much different than stock with a high flow drop-in replacement filter. Get air in first, then worry about temp. Truthfully, what is cold air when its 100+ outside anyway? At one point we did consider them to make our tubes for us and for us to supply them with filters but it never panned out.

[phuggit]

After I put a K&N and Flowmaster exhaust system on my F150 I read an article in Trucking magazine which stated performance gains would only be reached above 3000rpm with the mods.

[Toomstone]

thats what im looking to put on my f150 sometime, the k&n and the flowmaster 50 series... probably in a few months

[phuggit]

I can't tell you if I noticed any performance gains, because I did the mods as soon as I bought the truck.
If nothing else it sounds better.

[Toomstone]

they do sound much better... and there also together about half as much as a hypertech that gets you 30 hp too. you can get about 11 hp as it said above w/ the k&n and 5 to 10% gain with an exhaust

[CA Stu]

If you're going to add a less restrictive intake and exhaust and a "chip" and really want to maximize your investment, spend an extra $500 or so and get a set of headers too.

[Toomstone]

how expensive are headers and what kind of hp gains do u get???

[CA Stu]

I paid $550 for Doug Thorley headers for my 96 Dodge 5.9l (360) Ram 1500, $300 for the install.
I never ran it on a dyno, but from my seat of the pants dyno, I'm sure I picked up a load of low end power and torque. Good for towing, ya know.
Thanks

PS I have since traded in that truck and got a diesel.

toomstone. I have a Superchip with a Gibson Exhaust, and it works pretty well. I have a couple of friends that have tried different chips, and have burned cylinder heads from the engine running too lean. The Superchip folks will create a custom program for your vehicle..

I just bought a 2000 Ford Expedition 5.4 with 59K miles. Its lifed with 35" tires and no mods to the motor that I can tell. Anybody got parts for this, cheap? Air intake, exhasut system, programmer. I noticed a difference when I did these things to my Dodge Ram.
