Pyscotty Airbox

Banshe, I've been considering it and would apprecieate it if you'd bring the filter.

Pete, I have an RE-0880 installed in my truck for the last couple of months... so I'll show you that along with the prefilter on it also. The filter isn't so bad alone, but with a foam prefilter you get a whistle that actually sounds like the turbo.

Honestly, I am looking to go away from the RE-0880, because I noticed that when I really stomp on the throttle, the RE-0880 can't handle the air flow and actually collapses. I am going to go with SportBikes recommendation and go with one of the new K & N extreme flow RX-4070 filters instead.

Has anyone that has a Psychotty system, noticed any problems with their RE-08880's collapsing?

Kev my 0880 hasn't collasped,even with 40+ boost(really need a 50# gauge)Scott says the openings on the turbo inlet side of the Psychotty have to remain open to prevent this.

I sealed the bottom of my housing and the filter collasped, I built a cage for the inside and it collasped around it there is alot of air flow at 38-40 PSI of boost. Is the RX-4070 the same sized filter?

Well, at least I now I know that I am not not the only one with this problems. Af far as teh RX-4070... I don't know, Sportbike told me that he has one on the way... I will be ordering mine soon enough, so I will pass on any info that I get.

Dee,I wonder if your first collapse weakened the 0880 so that it's more prone to collapsing again.
I figure you probably made a cone from hardware cloth or the likes to prevent this. I'd be on the watch just in case the your cage chafes a hole in the 0880.

Lot of folks don't realize just how much airflow our turbos create,if you plug the outlet of a 5hp shop vac with a pressure gauge you will only get about 5 psi,if you can imagine a shop vac putting out 4-6 times more air while blowing you will get a good idea. Our turbos at 20 psi boost would make one he// of a leaf blower.

Bill, I am on my second one the first collapse did my first one in. I was using some regular old hanger material for my cage.

During a service at my local dodge dealer the
service manager noticed my psychotty. He can't believe it doesn't suck water and snow
into the filter, given the opening into the cowl and the amount of air the engine sucks.
After his comments, I went home and inspected the filter and housing. There was ice in the bottom of the housing, and ice packed into the bottom of the turbo end of the RE-0880. When that ice melts, does the water find it's way into the engine? I'm beginning to think I should go back to the stock air box.

GWS - What you just said is the one and only thing that has kept me from purchasing a Psychotty Airbox.

That is a really good point I never thought of. Has anyone else noticed this with the airbox? Since I see snow 5 months a year, I think I'll stick with the stock airbox.

I've never had a problem with snow/ice/water on my Psychotty. It should run out the bottom end unless the filter is installed too flat. Take a look at the stock airbox,it has drain holes in the bottom...

I did some testing on my PSA at a car wash and no matter where I was spraying water it didn't have any water get into it. The inner lip stops this. Scotty did one hell of a job designing this to make sure this wouldn't be a problem.

Drawson, was the engine running when you conducted the test? I might agree that water would stay out of the filter with the engine off, but there is an amazing amount of suction even with the engine merely idling. This suction, I believe could easily draw water or snow into the pleats of the filter.
At high speed, the aerodynamics of the hood
would likely prevent a problem, but at low speed or when stopped with the engine operating, there is nothing to keep precipitation from being drawn into the psychotty. What happens when built up water, snow and ice around the filter are exposed to the draw of 40 lbs boost? I think it's time for Scott to conduct some more rigorous testing.

I have the AirBullDog Hood (since June/00) and had the Pyscotty before that. As for lower egt's, I think there both about the same. I mean just how much lower can it get? I think the throttle response is better when I'm at, for example, freeway speed. I changed because I didn't want to hear the turbo spooling up and down in my sleep after a long trip (ex-helipilot and after 28 yrs of hearing that turbine my ear is just too sensitive to it). I too found some moisture just too close to the Pyscotty filter after heavy rain but, I must admit the main reason I changed was the look of the AirBullDog Hood. So far I couldn't be happier with the hood.

If there is snow or ice on the ground,you are not going to make 40,30 or even 20psi of boost or else your truck is going to spin off the road. I have driven with my Psychotty in all weather conditions and have never had a problem. I've packed the cowl with snow and also sprayed the cowl with the high pressure hose at work and never had a wet filter.
The two areas of the PSA design are the lip and the open end. Water and snow isn't going to gravitate upward and around the lip. Yes the Cummins has a great amount of air rushing in,but water does not keep up with air moving at that velocity. If there happens to be any moisture that enters the air box it separates from the air as the air makes the sharp turn into the filter. Factory air boxes are that way also... the water separates from the air and drains at the bottom of the factory air box (Hondas are well known for that).

Yes I had the engine running, and no water in the housing, I had the hood open. I have had mine PSA for better than a year and ruffly 20K miles and drove in all type of weather and other than some bugs nothing else get in there.
