Anyone using the Scotty Air System on a 1st Gen?

[Archive]

I've been reading about how happy all the 2nd gen. owners are with this system. (K&N RE-0880 air filter w/pre-filter)
This seems to make sense to me. Any 1st gens out there using this filter? Will it work with our stock turbo intake hose?
I'm a little concerned about the filter being totally exposed in the engine compartment, as I am frequently in extremely dusty conditions. Is this mod really a worthwhile performance upgrade or is it more of a "I can sure hear the turbo now, so I must be going faster" situation? #ad

As always, your comments are appreciated.

Don,there are some people who don't recommend reuseable air filters as they are never as clean as a new one after they are washed. Also the first gen filter housing draws fresh air from outside the engine compartment which helps to reduce exhaust gas temps. This feature would be lost with this system I believe. Just my two cents.

Don,
I notice that you have installed a K&N already as I have. I have noticed benefits from the K&N filter in max boost of 1-2 psi, a slight increase in MPG, along with a decrease of 100-150 degrees in EGT's. This is about what they are saying that this combo is doing for the 2nd Gen trucks. I think that you may accomplish the same by just putting a pre-filter on your K&N along with cutting some holes in your stock air cleaner case.

cuttin holes in r sto air cleaner case will promote drawing hot air into the filter. The cross-sectional area of the intake tube to the filter is considerably greater than the cross-sectional area of the intake tube where it meets the turbo. If you've gotta increase the input to the filter housing, just plumb a piece of 6" PVC from the front bulkhead to the filter housing. I was going to do exactly that until I did the math and figured out it would be waasted effort. The 1st Gen filter setup with a K&N filter is excellent as is!

Hello Fellow First Gen'ers!

I have modified my K&N equipped OEM airbox my drilling "Swiss Cheesing" the existing housing as described by "Lt" and others. My only concern is that now I'm just sucking increased Hot 'bad' air instead of the 'nice' cool dense air required to lower EGT's.

I have talked with Scott via email on whether the improved version, "Pshcotty" Air that requires the cutting of the massive 4 1/2" hole in the cowl to accomidate an intake source of cool, dense air. He had mentioned that he would be willing to look at providing "Pshcotty" Air for us First Gen'ers if there was enough demand. I told him I would be willing to help with testing or whatever else was required to pull off a system for our trucks. Maybe it's time to revisit this 'need' with "Scott D. " to see if he's serious about helping us out with reduced EGT and that cool "I must be making more power sound"!

The filter in our trucks (K&N) is bigger and has a larger flow area than the new trucks and is the barrel type. The filter is even larger than the 0880 that is in the Psycotty system. The new trucks have the small brick type filter so the Psycotty system is a huge benefit.
I was also talking with Scott over coffee a few months ago about looking at my truck to see if we could get more air. The improvement as far as I could see would be to get air plumbed from the cowl area as there is positive pressure area there while driving. Then leave the stock filter housing to hold the large K&N element.
Cutting holes in the housing (swiss cheese) is not a good idea as you are drawing 150 to 200 degree air from under the hood. At this point, the totally stock system with the duct from behind the bumper is the best setup until we figure out how to get cool air from the cowl area. You don't want under hood air.
An old farmer near home simply got some 4" PVC pipe and cut a hole through the bottom of his fender under the filter housing. Then has a 45 elbow facing forward just under the bumper. Its not pretty, but it seems to get him some more air.

I don't know if it helped performance, but I greatly reduced underhood temperature by punching two rows of louvers along the top of my fenders above the RAM insignia, and just below it. Whether it helps or not, I love the way it looks!
