Eagle 05 air cleaner upgrades to increase cfm for 8v92

[tr206]

So what are you others using to increase intake air for the big horses? I heard Eco System can someone elaborate on what filter that would be and where you get it?

When I turbo'd my 8V-71, I went with the same air cleaner can, but went from 6" to 7" intake and feed. Just go on the Donaldson.com website and select an air cleaner with the highest CFM. In your case you need 8" air hoses. Good luck, TomC

Cost wise, it might be prudent to find a salvage bus with a 8V92 and get the parts such as the bracket mounts and hose adapters. The air filter canister will be disposable in the Eco System once you have all the other parts. It would be best to find a parts Eagle. The adapter that goes between the air inlet box and the air filter can be rusted out, and finding one new can be hard to find and very expensive.

Thanks for the advise guys. Still researching measuring and fabricating in my mind.

I found this flexible tubing a little expensive but it would make installation from the air cleaner to the turbo ( with a reducer at the turbo in mind) a breeze as long as their are no rub points it should last for years. Here is a link.

You do know a top mounted turbo 8v92 is not a plug and play.takes a lot of fab work to install one,the floor needs to raise,the electrical JB has to be moved and the miter box has to move then all the piping intake and muffler,and with Jakes more work on the curb side

The 8v92 is already in the bus when I bought it, supposedly a guy by the name Clifford put bigger injectors in and tuned it going from 475hp factory to 500hp? It runs great but has the original intake and yes room is hard to come by that's the reason for a flexible intake tube idea all the jogs it would take to make a 7 or 8" aluminium intake pipe to the turbo would be a nightmare. I don't know if it is original but it already has a rubber 5" or maybe 5.5" hose from air cleaner housing to the turbo looks original.

consider dual smaller air filters if space is at a premium.

[tr206]

With the flexible hose and a Eco-lite filter I would have the room still have to measure twice to make sure.

The baffling effect in the construction of some of that furnace hose flex pipe is a significant disturber of air flow.

I can't remember the decrease, but depending, it amounts to the same as putting in smaller smooth pipe.

Not what you need for the gulping 8V...

Smooth inside is what you need.

Happy coaching!

I don't know it didn't say it was furnace ducting. It says it maintains smooth air flow.

Did you buy the Eagle from Lewis,if so to be clear I never did work on that bus he told several people I changed injectors and increased the HP that is not true

Clifford: I did and it doesn't like many other things surprise me . Sorry for the delayed response busy at work.
