air intake compatibility?

Guys knock it off. The feeling might be a placebo, but independent dyno tests (both hood open and closed) show an increase in power. They do add power but not a whole lot. To get s lot of power you have to damn near drain the bank account

well that escalated quickly.

im after a bit more noise from the truck and if it can make a couple hp then all the better. its gotta do something just by smoothing out the pipe running to the throttle body, getting rid of the expansion chamber, etc. i doubt id notice a few hp in a 6000 pound truck. but if it helps then bonus for me. i would just never pay full pop for one.

The old CIA argument gets me in the Christmas spirit..... I like mine. How much difference it makes is marginal at best. Get a Black Bear tune and be happy!

Several people have done dyno runs with and without them, and the Airaid is worth at least 10 wheel HP, which for $120 isn't bad. Too bad there's always doubting Thomas' and general idiots that can't comprehend or accept the data..

Let us put aside the name calling and the innuendo I previously posted, there is a couple of points I would like to point out about "dyno's :

 

1. Were your pulls on a "dyno jet" or a "mustang dyno"? The Mustang dyno is more real world the back drum adjusts to real road conditions using a braking system, the dyno jet is just free wheeling.

2. This is the calculation to use to determine HP - RWHP divided by .85 (for auto transmission) = FWHP using your results on the 6.2L engine you gained 30 FWHP with the cold air (I doubt it).

3. This is the calculation to use to determine RWTQ - RWHP x5252 divided by 5400(red line) = RWTQ using your results on the 6.2L engine you SHOULD have gained 25.28 RWTQ.

 

Here is another point I would like you to consider:

 

 

To meet the Federal mandated MPG for the vehicle (to avoid a "gas guzzler tax") GM is notorious for running their engines lean from the factory. The leaner the WOT A/F ratio, the more horsepower the engine delivers, and the chances are multiplied for burning a valve.

 

1. Run your finger inside the lower tail pipe, do you have carbon on it? or is your tail pipe totally clean or with slight white residue? If it is the latter, your WOT A/F ratio is to lean.

2. Unless I missed it, your chart does not state the WOT A/F ratio.

 

You can not rely on dyno numbers, proof?

 

1. Sara (2001 Z28 5.7L, stock motor) with Y3000 2.5 str converter, 3.73:1 axle ratio, and heavily braced up - Mustang dyno 291 RWHP/283.02 RWTQ (@5400 RPM) THESE ARE LOW NUMBERS FOR THIS TYPE OF VEHICLE, my point?

My best standing 1/4 run (street tires) was 13.5. If I relied totally on the dyno numbers I could never reach that time or speed 101 mph.

 

Sara's WOT A/F ratio was set to 14.5:1(very lean) from the factory, the dyno tuner reset it @ 13.3:1. I now have slight carbon in my tailpipes after aggressive driving

i picked it up last night, gave it a good cleaning and im just gona grab some oil from a buddy and throw it in this weekend. i dont see a spot for the sensor to go, unless its a mass air style setup and it goes inline with the pipe. i havent opened my hood since gm rebuilt the motor in the summer so i dont even remember what it looks like under there, lol. the truck has a trifecta tune in it already, i may get the guy to alter the tune for e to include the air intake once i get it installed. hes pretty good to deal with when it comes to making adjustments.

[uchi]

also i tow with this truck all the time. its 90% work truck, so its mostly towing my 12 foot enclosed full of tools a a few thousand pounds of material. and in the summer it drags my 27 foot toy hauler camping and to the track, so even if i can find a few hp and a bit of torque in the mid range where shes hanging around while towing then im happy

[uchi]

i put it on today, here are my findings.

 

first, it fits but it seems to be about 2-3 inches too short, that wasnt an issues i just pushed the heatshield back a bit and attached it all from there. this kit didnt have a hole for the maf so a 1 inch bit along with some trimming and she fit in there and sealed up nicely. aside from that it fits.

 

i reset the computer in the process and got a 20 minute drive in. its not very loud, but loud enough for me to hear, but ive also got a 40 series flowmaster muffler on her so that probably eats up most of the noise.

 

right off the hop the truck felt more responsive off idle. it felt good before but now it feels like the truck had a lag at low revs. shes quite a bit more responsive down low which works great for me. cruising around town there isnt much difference but thats because she just drives around in 5th gear most of the time in an effort to conserve fuel. driving in tow mode she again feels more responsive than before. getting in the gas and letting her sing through the rev range i didnt really notice anything. this is likely because its a crew cab regular box sle with 4wd and weighs just shy of 6000 pounds, so a few hp really isnt going to be noticeable. im happy with it, ive got $100 in to this thing and cant complain

[chupe442]

Your truck is also in the process of doing some re calibration with the changes and disconnecting the battery. Glad you are happy with it.

[uchi]

im sure once its recalibrated ill notice a difference. ive had cars in the past where ive done this and theyve shown gains on the dyno, based on the large baffles and expansion chambers in the stock intake i dont doubt itll make a noticeable difference.

[BigBlueLB756]

Glad to see you finally got some information instead of opinions.

I'm happy with my K&N, too.

 

[uchi]

i towed with it the other day, probably around 3500 pounds. right off idle the truck pulls the weight a lot easier. its gotta be the half mile of expansion chambers that cause a lag in power down low. im happy with it for sure. also ive managed to find the sweet spot where i can hear it over my flowmaster, its about 3500 rpm, its also the trucks thirsty spot lol
