Small stuff for a Cummins. Haha.

Lots of comments. Vote too.

We may be able to have them build air plumbing and a heat shield if that would float everyones boat. Could help with the dust and allow for cooler running temps while hauling heavy or in extreme conditions.

Haha yep. Standard Lie-o-meter.

Better filtration is cheap compared to replacing rings or rebuilding an engine. The added airflow is a perk too.

300 dollars would be for the entire air intake kit. Around 200 for an airbox for the filter that would use factory plumbing. Both options with the air filter included. The filter alone is around the 80 dollar range. Still cheaper than replacing your factory filter 3 to 4 times to equal the mileage from just one of these filters.

The filter go for an average of 80 dollars.

Ok BHAF sizes and part numbers: These filters are available through Volant and built by Donaldson for them. They use the Powercore technology for the best flow, filtration and longevity. They can be back flushed with low pressure air if in extreme dust conditions and are water and moisture resistant. 8" long x 8" diameter filters on all BHAF options. Flow rates are 1300 CFM and the powercore can filter the air too! 4 inch flange: 61504 5 inch flange: 61502 6 inch offset flange: 61508

Gents please hit the poll and add to this. I will be updating information such as part numbers from the vendor for those who want a BHAF only option.

This is 100% true. AH64ID is correct. Bearings see the highest wear on startup and shut down because the oil pressure is not adequate to provide lubrication. The wear is minor but in the long run will remove a tiny amount of material from the bearing surface. You see this with regular oil analysis as an increase of wear metals. Mostly lead, tin and copper. Newer trucks may use a polymer bonded bearing to help prevent premature wear from shut down and start-up.

I myself run synthetic because my engine seems to perform better with it. That said I highly recommend Rotella products both regular dino and synthetic.

Haha. I've always known it as the Lie-o-meter. Those numbers do sound like hand calculated values but let's see what he says.

It is a pricy option but will help those in higher dust environments and extreme conditions. I fit in that category for sure. There is a just filter option also and is available for purchase. I will post that info here in a bit. I'm sure they would give us some sort of additional cold air duct work that depending on location could be altered to draw heated air during winter months.

Yes that is correct. The factory airbox itself is a key restriction point in our trucks air system. Even though a factory element can flow neat 480 CFM of air the box itself can not ingest that amount of air fast enough to properly supply even the factory turbo which can suck down around 900 plus CFM of air. This causes some compressor inefficiency and additional heat.

The more people that respond the better so spread the word.

Just got off the phone with the vendor again and for a full kit including duct work, filter and all we are looking in the ball park of the 300 dollar range. If they develop an air box only to utilize factory plumbing thar would be in the 200 dollar range. These filters again can last up to 100,000 miles with typical conditions, filter the air better than OE and the current BHAF options and flow much more than the factory air box and BHAF options.

The filter flow rate for the BHAF I am using is 1300 CFM according to a gentleman I spoke with. There is the possibility that an oval filter would be used rather than the round filter and it flows 150 CFM more than the round filter. Currently the filter I am using is 8 inches long, 8 inches diameter and has a 5 inch flange. The same element can also receive a 4 inch flange or 6 inch offset flange. The oval filter I'm still digging to get the dimensions.

80 MPH at 17.5 average fuel economy is not too shabby.

No word on pricing but the filter element is a Donaldson Powercore. The vendor wants to see if there is enough interest in this.

These things happen. They offer a dual disc that's rated from factory power to 500 hp also that is engineered for heavy towing. Might give them a ring and see if they can work with you.

So gents I have come to a conclusion that this filter as a BHAF will work well in our application. I would like some feedback from as many people as possible though. The vendor is willing to produce an air filter box for this filter or another that has about 150 CFM of additional flow if there is enough people that would like going the airbox route. So if you would like an airbox with these high flow and high filtration filters in a reply write in AIR BOX, if not write in BHAF. I will be emailing the link to this thread to the vendor of the product so spread the word. They are very excited to hear from us guys running trucks from 1994 - 2002. Whenever you guys are ready go!

Definitely something that should be noted on there that is not. Valair themselves will tell you that the organic single disc is not for heavy towing. If you go to the website they have info on it and clutch recommendations depending on use. The clutch you have is recommended as a factory upgrade that's all that is shown.

Could be a number of things causing the clutch to go earlier than the factory. If you used the single disc organic clutch Valair does not recommend towing over 10,000 with regularity. They say use the organic dual disc clutch.

As far as I remember TPS was there but Load and shaft speed were not.

I would do this but unfortunately I do not tow much. I have in the past with this truck but that is prior to owning the truck and at that point IAT was fairly low 120 was the highest I remember. This was a light trailer and it was very cold out. If I remember it was around 30 degrees in the Texas hill country where the IAT jumped up to 120. At that point the owner had an oiled air filter on the truck with an HE351VE turbo. A lot has changed since then. Just a side note this is an actual air filter since you and I are sticklers for filtration.
