Sorry Scotty

[Archive]

I have a Psychotty air unit on my 3500 hauler and am very pleased with it,dropped EGTs about 150. On my 2500 I don't pull a load much but with my right foot problem I still manage to get the EGTs up there. Since I had the extra air box I decided to experiment. Drilled 2 7/8 holes in the left rear side of the the air box and another in the Psychotty firewall location. Connected the holes together with 2 1/2 shop vac hose,a perfect fit. Also drilled some 1/4 holes in bottom of the air box to drain any water that might get in. I am running a K&N filter. Test results-on my "known hill"EGT is down 100,engine is a bit louder(silencer ring might have to go back in),filter minder didn't move(before it went about half way). Before I could hit about 75 mph before backing off due to high EGT,now 95 with room to spare(ran out of hill). I'm sure that a Psycotty unit will flow more air but this is a cheap inbetween,all it cost me was a little time and scrap piece of hose I had laying around. Plus I didn't have to drill that monster hole that some of you guys are so afraid of. Think I'll call it Son of Psyhotty Jr.

Scott, ol' buddy, Illflem may have cost you some income from us middle-BOMBed folks (310&700 estimated #ad
). Not to mention that 4-1/2" #ad
hole still has me queasy, even after all the testimonials on the other threads... after all, power being addictive like it is, we may hafta do the aircannon thing anyway... hmmm, I wonder if my neighbor's shopvac is sitting around unsupervised??

A friend of mine wanted to this install today,but I didn't have enough shopvac hose. We scrounged around and found some 3"RV dump hose,it actually worked much better,still drilled 2 7/8 holes.

Illflem,
Great post!! I was trying to think of a way to do what you did (small mind takes long time to spool up).
Thanks for posting the egt's that is significant reduction for a simple mod!!!!
I will be cutting my tomorrow #ad

Like to ask a favor. Will you pull your hose off the turbo housing and check the turbo vanes to see if they have any black on them. Have a running debate with a guy that our turbos suck the oil off the K&N's and it builds up on the turbo vanes. Thanks much.

Mike ...

Ever since I put the K&N on ... my turbo compressor vanes are a dirty oily black. Haven't had any performance problems yet ... I see the same problem on the marine engines we use with the K&N's . . no turbo failures.

Mike, the K&N filtering oil will only be sucked off the filter and subsequently ingested IF the filter element has been OVER oiled.

Checked both my rigs running K&N,turbo fans were clean. I would have drilled a 4 or 4 1/2 hole but 3" is about the largest you can do on the side of the airbox without hitting the clean side of the filter.

John . . I agree with you COMPLETELY ... however ... these K&N's I'm talking about came OILED from the K&N factory!

I had run a stock K&N filter for 50,000 miles and when I went to the RE-0880 filter my turbo blade had black build up on the out sides. I used a q-tip and alcohol and cleaned it up. I have run the RE-0880 filter for 10,000 mile now, 3,000 with the Psycotty system and I checked it last night the turbo is clean. I pulled the OEM housing off the shelf and looked it over good and can see where air was bypassing the filter on the edge that was closest to the turbo. I had greased the sides since the beginning. After seeing how clean it is now I think the problem is with the stock housing and flat filter not the K&N.

How do you hook the hoses in the holes without leaking or slipping of the hose. I guess what Im trying to say is what did you use to clamp the hose.

The holes I drilled were slightly smaller than the OD of the hose and hose had a sprial wire inside so I basically screwed the hose in about an inch. The hose will also make a 90 degree turn at each end which also helps to hold it in. I don't think a tight fit is all that important,just look at the gap between between the airbox and the plastic flange on the fender wall,or the gap around both ends of a Psychotty for that matter.

My turbo vanes were clean as a whistle, and I'm running 30 pounds of boost. I'm running factory box and K&N, so I periodically yank the hose off and check it, I just have a hard time trusting that grease to seal the edges, though so far it has.

illflem,
Sounds like an awesome idea. Can you post a pic or 2?

illflem, I have been trying to get on line for sometime now. Been wanting to ask if you covered up the old stock air in let. If not, would it not stand to reason that there would be more air pressure into the filter with the stock hole patched/covered? Also, how about pictures. Have you any for us to peer in awe at?

------------------

Turbo,No I didn't cover the old air hole,but I don't think it's nessary,it still improves preformance. I think Dodge designed the air hole small to keep down boost and EGTs,cheap way to protect the engine without haveing to throw in a EGT gauge as stock. As far as pictures,I'm somewhat new to this digital world and threw up my hands trying to figure out how to post them. My digital cameras' instructions failed to tell how. If someone feels like walking me though via E-mail I'll post pictures ASAP.

The coil hose idea sounds good.

I'd been thinking of doing this with large electrical conduit (plastic) since there are lots of interesting bulkhead fittings that might work real well.

thanks guys for getting back to me on the black on the turbo. I love these running debates on which filter to use and the down sides of them!

The black on your turbo from using the K&N or other oil filters isn't really your major worry. This black greasy film gets pushed through your intercooler and will cause premature engine wear. Not a big deal if you do not plan to put 200K on your eng.

I had a K&N, not over oiled either. It's possible mine was defective, who knows. But cummins highly recommends NOT using the K&N or ANY oil air filter.

As per Cummins Southwest, Phx AZ July 31st, 2000.

Of course they Highly recommend NOT bombing either, and those babies are staying! #ad

SteveAZ,
Did you notice a difference(other than turbo whistle) with the OE paper filter? Do you feel like you lost power. How about EGT and boost readings? Just curious.

I put in a K&N a couple of days ago, and I can't tell any difference. I am not bombed yet(except exhaust). People talk about turbo whistle? Yes, I can hear it with the K&N, but I could also hear it with the OE filter. I am thinking about using the Mopar paper filter and just changing it every 5-7K miles.
