Is this air cleaner any good?

[guybb3]

The flat filters had their problems, that is what our Suburban came with. It may have been a little earlier on the round filters and they are the ones I was referring to. The round filter setups are a very good upgrade. If the 506 blocks were as good an upgrade as the round filters to the flat panels, you would never see a crack in one!

I agree, Bobbie. I had the flat filter (with a K&N filter) and upgraded to the K47 box. I don't even know why I have the old box in the garage. That will be getting thrown out in the Spring garage cleaning!!

Thanks for sharing the link.

K&N oiled filters...

I have been running them on my Harleys for years. I have almost $5K invested in 103 cubic inch 2 cylinder air cooled V-twin and would not hesitate to run a K&N filter.

The only REAL data that I have is based on results from a 250I dyno run on my Harely. Pulled off the K&N filter & the final Tq & Hp numbers were the same as with it on. Not scientific but I closely monitor my intake track & it's always spotless, I realize this may not have any bearing comparing my motorcycle to a truck...but it's the only experience I have with K&N filters.

Kinda hard for me to fathom the K&N comes so highly recommended for my modded $5K air cooled V twin motor but it's not very well suited or recommended for my $3300 truck...maybe all these years I have been a fool

I'm running my zero cost handmade setup on my 6.5, see pic.. and based on turbine efficiencies I am planning to add a rim / seal to my ho made that will limit some or hopefully most of the hot under hood air for the summer months.

Thanks again for sharing the info :thumbsup:

I have a K&N on my Gixxer as well. I'll tell you this, though, I'm putting an Amsoil oilless one on as soon as Spring comes. I never saw dust in the intake of ANYTHING I had one on, until my 6.5. I definitely had some dust in the rubber intake elbow that stopped when I put a paper filter back on.

SCARY!!!

I think people don't put enough emphasis on IAT's (Intake Air Temp) These will not show up as fast on the EGT gauge, but not only do high IAT's, add to EGT heat, but the heads lose whatever cooling the desired cool IAT's will do, causing the heads to get that much hotter. Cooling them is a weakness in these engines, and they are prone to crack. Same with the block.

I'd do anything possible to keep the coolant temps in check, and keep those IAT's down as well as monitoring the EGT's.

I blame my head failure last year due to high IAT's, a chunk came off the valve, causing havoc.

I did have my plow on, but this year I put a scanner on it with plow on, as I was adjusting my fan clutch to kick on sooner, for this reason, and those IAT's would climb over 200+ easily with the plow on.

During the head/valve issue last year, I was pushin my truck good, under 1000 EGT's so I thought I was safe, but if i had my scanner hooked up, I can't even imagine how high my IAT's would have been. I wished it defueled, instead I cooked a head (amazingly drivers side). Didn't warm it, but the high IAT's HAD to have an effect on that valve crumbling apart.

The turbo-Master was installed later, and that drops EGT's alot, but there is defanately added cooling benefits to the coldest IAT's possible.

I would not use an open filter in the engine bays. It is sucking right from the hot fan wash air.

Sell it on Ebay with the K&N if you still have it. I've sold 3 of them. Got just enough to justify shipping them

Well let me reply with this Matt.

I'm a controls Engineer at one of the largest Inland Refineries in the USA. We have 40,000 HP power recovery turbine we operate on the fluid Cat cracker. The inlet temps to this monster definitely effect the performance and exhaust outlet temp, but the thing that has the largest impact is the discharge pressure, more pressure push's the compressor up the curve to it's limits and that discharge temperature directly tracks the machines delta pressure.

Not trying to negate the impact of the inlet temperature any, just saying it's only one variable into the mix & not the one that has the largest effect.

So you're saying that this is probably why the ATT works so well is it's lack of backpressure, compared to the GM-X series turbo?

 

[Crankme69]

Definitely one of the major reasons...:yup:

 

[Crankme69]

Do any of you have a link to testing & data that has been done / documented on the air intake delivery temps that measures the effect on the inlet plenum temperatures?

Anyone seen this air cleaner setup before? I was just wondering if its better then the stock filter.

That does not look like a AZ DIY kit to me. Looks like one of the quality units sold by a vendor here...that somebody has added another elbow to.
