I Drive a Lear-Jet...

[StephenDelany]

:-laf This is too funny. I installed K&N Cone-Type Filter, Intake Tube and Heat-Shield Kit (I can't remember correct name) last night and did not get a chance to test drive since dinner was waiting.

This morning I fire up and head-to to work... Oo. I turned my truck into a Lear Jet!! This thing whistles with any throttle input, spools up and spools down, generates more boost more quickly... it is WILD!

If you liked the opening sequences to Top Gun with the Tomcats jockeying around the deck of the carrier and their turbines throttling up and down your gonna' love this!

Sorry, I got a little carried away... but DO IT!!!

Be carefull! There is a reason K&N filters whistle so much. But I'll shut up,I'm sure you have heard the lecture before. But it does sound sweet,huh?

I still have oil and dirt on my turbo fin from a K & N filter. It was a brand new filter too! Everybody always tells me that I put too much oil on it when I cleaned it, but I had not cleaned it yet! Brand new out of the box and it "dusted" my turbo!

 

[PC12Driver]

Same here. No matter what I did, I always ended up with a gritty, oily film on my compressor blades. No problems since I put in the AFE PG7.



I tossed the K&N. I didn't even want to give it away.

It does sound cool, until you tow in the mountains, it can become very annoying and almost painful to listen to the turbo whine.



But don't get me started on K & N #@$%! #@$%! #@$%! #@$%! #@$%!

 

[StephenDelany]

I drive only on-road in Florida where the dust situation isn't bad at all (heat and humidity is another story) and I'm hoping that the K&N's reputation for letting a little bit of Mother Nature" thru to the turbo won't be an issue.

I had a K&N Airbox element for the last 96,000 miles and the turbo hose and inside of airbox have been spotless. I have occasionally cleaned my turbo compressor vanes with a little brake cleaner on a clean rag during an oil change. Just enough to take the light film off the face of the blades. It doesn,t seem to have bothered it and the tolerance of the shaft and smoothness of the bearing feels like new. The spool-up response is still very quick.

I'm pretty sure it is a more serious unit but I just can't justify the kind of dollars that an AFE calls for, particularly at my wheezy horsepower lever.

Certainly eager to hear feed-back...



Thanks, Steve

Think about adding the pre-filter. Comes in colors... .

I think the only way you can really measure the efficiency is by oil sampling and the silica numbers.



I know how you feel, I love tunnels.

 

[CGriffith]

I'm not a fan of K&N either. Not the response that you hoped for I'm sure. Don't worry I know a couple guys with a fair jag of miles sucked through a K&N. I couldn't find it but blackstones last news letter had some discussion of space dust. Basically it was about issues caused by pilots allowing unfiltered air into the engine after they reached cruising altitude. They say that all air has "space dust" in it that causes high wear levels in the top end of the engine. They sited example of sediment layers on earth and such. Just so you know that what you think is clean air might not be. We're only telling you this because we don't want to see you waste your money on parts.



Did you pull the silencer ring out of the turbo. Makes a stock truck really sing. I love the sound of a turbo working too.

 

[DieselMinded]

Want Whisle

THIS WILL MAKE HER SING... . :-laf



this is the DMINTAKE



A Bright Idea I had ..... till the test drive ... WOW to loud !! and after full boost it started to collape :-laf

If you REALLY want it to sound like a jet, disconnect the exaust just before the cat, where it exits under the cab. Wire the cat and muffler up out of the way and go drive.



edit: just noticed you have a 5 speed, those sound more like a log truck. When you shift the turbo slows down and it sounds(from a distance) like someone chirping their tires. On my automatic, the rpm's stay pretty much the same, so when I was testing/cleaning my cat, I drove for a few weeks with the short exhaust. It was noisy, but with it spooled up at a constant rpm, you could hear it over a mile away, and it sounded remarkably like a jet engine.

 

[jeepit]

Yep. Mine sounds loud thru the 1600 to 2000 rpm range. Under that or over no problem. Going up hill you need earplugs or turn up the tunes

 

[RMalone]

The pro-stock truck that ran low 9's at IRP, now that sucker sounded like a jumbo jet. I was at the vendors booths when he made his first run, and my reaction was "what the **** was that!!" sounded like the entire bleachers were shaking apart! Sorry to get off topic!

 

[Texas Diesel]

The whistling is from the intake air passing though the metal grid where the filter element should be :-laf

Could you tell us a little bit more about that setup? I was thinking about making something like that for my 3rd gen.

that is the important part... it did not flow enough air and started to colapse in on its self... bhaf isn't the loudest out there but it isn't overly quiet either [and is pretty inexpensive]. if i could get someone to video my truck [or find a proper tripod to borrow to self video] i could grab some video with audio to hear how my bhaf sounds...

 

[Billy Golightly]

Some filters have a plastic or metal skeleton like apparatus that the filter is made around to keep it collapsing. Wonder if that would solve it? I'm thinking like an automtive cone style from Uni, http://www.unifilter.com/automotive.htm
