Why use a pschotty?

[azcummins]

So I got Todd's replacement for the pschotty, (Aluminum instead of plastic) and I really like the unit but that 4. 5" hole doesn't strike my nerve too well.

Since I already had my K&N RE-0880 I slapped it on knowing that this was the orignal Pschotty unit. The turbo is spooling quicker and the turbo REALLY SCREAMS so I don't see why I can't just run the Filter without the box? K&N makes a foam slip over sleeve to keep most of the dirty out.

My only concern would be when cummins steam cleans the engine for me. I guess I'd have to cover it up real well to keep water from coming in.

What do you guys think?

Mark. .

I run the RE-0880 with the pre-filter, 25-0880, and from all the posts with photo's I've seen in the archives, so do a lot of other people. I don't go off road, so I'm not really worried about dirt, in fact if you think about it, look at all the photo's of the various gassers/ricer's, etc. in the magazines running "bare" K&N applications of many different configurations.

I have a very bombed 97 Dakota with a tube-intake with a big, bare K&N cone (just like RE-0880, only a little smaller) filter. In over 20K the filter doesn't even begin to look like it's building up residue.

I'm sticking with the 25-0880 just because I've seen some posts re: residue on the turbo blades, etc. If you're really worried about excessive dirt exposure, K&N makes a "sock" cover... can't 'umember the PN. According to K&N it does restrict flow by approx. 10% as opposed to something like 3% for the 25'er.

I think this system could easily be "protected" for engine cleaning.

I'm in the minority here, but I really don't see how the boxes help air-flow... . you're cramming the RE-0880 inside and the only source for air entry is the end of the cone, which unless you use the new model RX-4070, is covered by a rubber end cap. I will concede that the cowl entry probably has merit. We TDR'ers are the only group using K&N filters in this fashion(to my knowledge)and I just don't think it makes sense to "enclose" the filtering area of the filter which I thought was there to allow for 360 degree air circulation. Sorry for the ramble... .

24V-DSL,

I think you are right about covering the cone. The filter is really crammed into that small space and the only way to get air to it is to pull it through the 4. 5" hole.

Some people say if you run just the filter then you are sucking only hot air. This may be right, but my turbo isn't complaining much b/c it screams when I step on it. hehehehehe...

Summit racing has the 25-0880 for $22 so I think I'll do that. That is the foam slip over sleeve right?

The main purpose of the Psychotty drawing air from the windshield cowling is not entirely for more air volume, its mostly there so you are not sucking in hot engine compartment air, that is the main advantage of the unit. The cooler the air, the more dense it is which equals more air to the cylinders which of course equals more power. So despite the restriction the Psychotty causes do to its shape, it makes up for it in supplying much cooler air to the engine. As far as dilling the 4. 5" hole, Dont let the 4. 5" hole scare you, its easy. I used a cordless drill and hole saw, that metal is very thin and it is not going to hurt structural integrity in any way. They also include a rubber grommet so you will not see any bare metal edges. If you ever take the Psychotty unit out, all you need is a piece of sheetmetal and some silicone and the hole is gone. I am also using Jannetty racings heat shield which helps to keep the turbo's heat away from the induction. whether you are using the Psychotty unit or not, it is a good investment ($35. 00) and it uses the stock air box mounting studs so there are no holes to drill. Looks really cool too. It comes in satin aluminum but i painted mine with BBQ black paint so it looks like it came from the factory that way.

Mark... . you're correct, but it sure doesn't look like "foam" to me... . more like a very tight plastic/weave design. Be sure you don't over-oil the 25-er, or it might bleed through to the RE0880, and then into the turbo. I'm sure you know the RE-0880 is already pre-oiled.

I used the spray bottle K&N oil technique and turned the filter inside and out to oil, but again, not heavily. I let it sit for a couple of days to see if I got much drip/pooling and then I wiped it down inside and out with several towels. That seemed to be enough. I can run my fingers over the surface and pick up slight oily film. I've used K&N's on my gassers for years, and learned the hard, messy way that over-oiling is easy to do and a PITA to undo.

All I can say is that running a bare 0880 didn't lower my EGTs at all, the Phscotty lowered them 150°. You decide.

 

[radixr]

Has anyone installed the psychotty when an exhaust brake is already installed? It doesn't look like there is room for both.

I have the PSA and a BD exhaust brake. Both work beautifully and neither creates a problem for the other.

Scotty's invention is one of the finest after-market inventions out there. I witnessed a drop of 150 degrees throughout the entire ET range since installing his unit and others have reported the same or similar reductions in temperature. Needless to say it gets old reading posts from some of the new members who haven't a clue of the hard work and Scott put into its development. It amazes me how quick to criticize some have been but bear in mind Scotty's invention shows tremendous talent and creativity; the "improvements" being offered by others show almost none at all.

I understand Scott doesn't visit the website much anymore. After reading some of the posts regarding his invention I understand why.

I think his invention is great, i have one in my truck and i recomend it to friends. My only problem with it is the quality, the unit i recieved was literally falling apart. and the connector pipe they sent was not cut right. I was also told it was shipping the next day when in fact, it was shipped 9 days later. And after all that, i was charged $145. 00 plus shipping and it did not even include the filter. I was not alone with this problem. But you are right, he does deserve alot of credit for taking the time, effort and expense to create an item that performs very well. I will still continue to tell other Cummins owners i meet about the Psychotty unit and its advantages.

EMDDIESEL, I have to wonder if whoever is making these is not suddenly dropping the ball. I got mine in January, seems to be built okay.
My hat is also off to the designers, Scott Pirsak and Evan Beck, who did all the R+D to come up with something that actually works as advertised, rare in these days !

I think Scott deserves a lot of Kudos for his work and ingenuity in this case. However, not everyone can justify $150 for an airbox so if there is an alternative that works almost as well and is cheaper, people will take the alternative.

Another thought with Todd's aluminum airbox is that if it really does get really hot, then the cool air that comes from the cowl will be heated by the hot airbox so you might as well just run straight air, no airbox. However, if you know of a way to make it heat resistant, then the engine would probably profit from lots of COOL air.

Carbon Fiber is heat resistant right? HEHEHEHE... .

The aluminum version would be perfect if you wrapped it with thick, aluminised foam insulation like a company called Dynamat makes. That would eliminate the heat problem since Aluminum absorbs heat like a sponge

Mark... .

A little more info. Today, I installed the Jannetty Racing heat shield. It completely isolates the RE-0880/25-0880 from the turbo and engine. It does not touch any part of the K&N, and is tall enough so that with the hood closed the top of the shield probably fits very close to the inner hood.

I haven't tested this system, but it seems to me that "shielding" the K&N and still allowing cool air in from the fender-well should mean cooler temps. In any event, I'm through messing with this system. Diesels and gassers don't seem to respond the same to exhaust and air-flow modifications. All I know is, on my 97 Dakota gasser, when I put on Mopar headers, high-flow cat, cat-back exhaust and FIPK K&N air-intake, it totally woke the truck up and improved my mileage by 1. 5 mpg.

Also, I took off the 25-0880 to look at the RE. The RE looks new, out of the box. The 25'r shows some dirt on the outside, but none on the inside, after 5K miles.

EMDDIESEL... ... thanks for steering me to the Jannetty. You're right... . it's "cool", or at least we hope so. #ad

Glad it worked out for you. They are a good bunch of people who know alot of good tricks.
