Not impressed with Psychotty!

[drawson]

Mine showed a good drop in EGT from the very beginning. All I had was the #11 plate then and open 3" exhaust and got 150 deg drop towing and 100 deg empty. After further bombing injectors and what not I am still very happy with the system. I have drilled 3 2" holes in the plasic cowl peice after hearing the air being sucked through the cowl at shut down. I also just added a AFE filter today and will be sealing off the back side to see how this helps.

Re-Test results with and without pantyhose "pre-filter" (again, 2 runs in opposite direction with each set-up, 0-95mph, with cool down between tests):



With "Pre-filter" - 1st run-1344, 2nd run-1351

Without "pre-filter" - 1st run-1344, 2nd run 1344



Obvious conclusion is that the pantyhose offers very little (effectively no) restriction. Think about it - this filter is probably 2X the diameter of my wife's leg, so this thing is stretched pretty thin. You can see through it very well.



First off, please don't think I'm being negative about anything or anyone. I bought it, tested it to see the performance, and posted my results. I've tried to keep the testing very consistent. If anyone has any comments, tips, etc. , please feel free to share. I'm in this to lower my EGT some more, nothing else.



Rob, My thoughts exactly. Wrap one of those pre-filters around your face and do a few 100yard dashes. Do the same with the pantyhose stretched thin. I think I can guess which is harder to breath through.



Mediccummin, Sounds exactly like how mine fit, PIA to install, hose made oval instead of round (this could contribute some, but not real distorted, so I wouldn't think much). What was your third set-up? 1 was Psychotty and another was 0880 w/ prefilter only, right?



Bill, I tow very little, so I haven't tested it towing. Your statement may very well be 100% accurate. But we haven't heard the conditions on all these posts about the Psychotty. I guess we need to hear from all of the other guys that saw a big difference - what were the exact conditions? That's also why I asked, what was your exact set-up previous to Psychotty.



Clark, I understand what you're saying and that may be true, but I'm still comparing two things on an equal basis. Everyone has said the same thing about the stock set-up being marginal for mildly upgraded trucks, and that the Psychotty flows more than the stock box. My tests simply say that, in my test conditions (which are based on the reason I got the Psychotty), the Psychotty is not as good as a K&N in the stock box with the "snorkel" removed.



About a year ago, I read a post by Joe D. talking about pulling out that "snorkel". At that time I had 275's, PE, and K&N in the stock box. I could pull the filter minder down to 50%. I pulled the "snorkel" and haven't pulled it down since. That thing is definitely the 1st big restriction in the stock setup.



Right now, I'm still scratching my head. I want the best possible (cheap) intake that I can come up with. I'll either perform Bill's "Sorry Scotty" mod's to the stock box (since I already have the hole in the cowl) and replace the snorkel (that way all cool air is pulled in), or I'll cut a hole in the side of the Psychotty and connect it to the hole in the fender. Or both, but a few guys have asked about buying the Psychotty, so I hate to mangle it.



Any suggestions???

What was the name of the new air intake that draws air from under the bumper? Seems like thats a decent alternative. I can't figure how to get 4" ducting down there though.

TxRam,

what about just using the 0880 K&N filter with a Jannetty Racing heat shield? Does that little heat shield thing he sells do anything at all? Doesn't look like it would really seal tight enough to keep all that much hot air out of the way.

'956Wheel,

Unless it is for performance upgrade I wouldn't fool around with it either. Pulling the silencer ring off the turbo was not a performance upgrade and never was meant to be. Just noise maker.



I think the physcotty was meant for those hauling big loads.

I don't think doing wot is the same as pulling heavy trailer (under load).



As putting intake hose down under bumber not a great idea, sounds like a water syphon to me.

I have the Jannetty heat shield. It does work well to keep the heat from radiating from the Turbine to the air filter. It was never designed to be airtight or completley block all the heat. You can tell the differnce just by putting your hand there with the heat shield. Its alot cooler. Not bad for 40 bucks

Plus, I like the way it looks!

Missouri Mule, In reading many of these posts it seems to me that some CTD owners just gotta "reverse engineer" a PROVEN engine. Yeah, the Ford boys are at it too, Henry, at work, spent 2000. + on his stroke and then he had to show the (stock) Dodge up... did not work, always an excuse as to why the Ford, with all the add-ons could not do it.



I went through the trouble of removing the cat... what a waste of time, but the bros on the site had me a believer... "it was clogged at 57,000 miles", Bull---- mine had 150,000+ miles on it when I performed the "surgery" and you bet you could see light through it! Then some of the bros are "gutting the cat", yes I posted the danger in doing so as there are carcinogins (sp) in the cat, thats right***** CANCER CAUSING***** heavy metals, scrap cats are toxic waste!



So lets face it there is a place for scepticism. I may get it for this one but do not count on someone here knowing more than you!



Then there are the "I better take it to the dealer" bros... get real, would you let a kid work on your injection pump! This is a precision piece of machinery, read the book 30+ times then do it yourself!

I think Missourimule's onto it

TXRam, I think Missourimule hit it on the head. . . the way you are driving your truck and making your runs is the reason you aren't seeing much improvement.



If you are taking off at WOT and running up to 95, much of your EGTs are generated before you reach any substantial velocity. Remember you are fueling it hard just to get your truck launced and headed down the road! When you do reach speeds where the ram effect kicks in and helps run EGTs down, your run is over. I'll bet if you start off at a steady 70 or 80mph cruise for a couple miles and then drop the hammer to 100-110, you might notice more improvement. Or go find a trailer and a hill.



Well that's my theory anyway .

I tried the Psychotty and got a small decrease in mileage. I then removed the housing and left the firewall hole open, put a "No Nonsense" pre-filter on, (after removing the wife from it!) and installed a Geno's Hitco exhaust blanket. The 0880 is drawing from both the firewall and fender, with little or no restriction.

 

[mediccummin]

my results today

After reading this I wanted to try my 3 in one day since I had time. This is without towing, 90 degrees out, same run for each, psychotty hole sealed. Stock box with K&N, with snorkel at 70mph, level ground, egt was 650, up grade egt was 1100... ... ... K&N 0880 with 25-0880 pre filter alone. same area, same speed, egt 600 level, and 1100 grade... ... ... ... With psychotty and K&N 0880, same area, same speed, egt 700 level, and 1050 grade... ... ... Of course this is my own test and my own results. Still not real happy. Gonna see how it does towing tom. on camping trip. Then I'll decide if it stays or goes. And a question? has anyone had a problem with water getting inside? It is known some things work for others but not for some. Dwayne.

P. S. Right now, as we speak, I am in the production mode of high performance muffler bearings so act now to obtain the best price! These bearings will be made of Hastalloy with TIN coating to enhance their long term heat and wear resistance. [/B]

Let me know when those bearings are ready. I will gladly field test a set for you.

Unloaded at 70mph (level) I'm making 6psi boost and only burning 540-550deg (preturbo). WOT up a 7% climb,my EGT's only get to 850deg max! Before the Psychotty with just the 0880,my temps were 600deg at 6psi. This is with DD stage II's and a straight pipe 3" exhaust and a Jacobs e-brake. these temps are the same from WA down to CA and NV.



I have tested and verified the temp decrease with the Psychotty. With CB's in both (unloaded) trucks reporting back and forth over the same terrain/trip,my 4x4QC 24v 6spd with Psychotty was tested against a 4x2QC 24v 6spd with RE-0880 that weighs 1200 lbs less,and I was always 50-75 deg less than the 2wd!



I don't know how you can test better results that this!

short of spending $ 1400 on the Air Bulldog junk

Hammer, I think everyone is entitled to their opinion however, that remark was unfounded and uncalled for. The Air Bulldog induction hood is a very worthwhile accessory, providing a substantial EGT reduction while at the same time reducing engine noise thanks to its double wall fiberglass construction. Additionally, I have NEVER had better oil analysis reports than the last three... the Air Bulldog fiberglass replacement air box base along with the K&N flat panel filter seal extremely well. My last three silicon numbers were: 4, 4, and 5. The last analysis (5) was due to the oil being used another 7. 5k from the previous sampling... so in essence, I only gained 1 PPM for an additional 7. 5k mileage on the oil (however, there was 1. 5 qt. of makeup oil added at the mid sampling point).



..... did I mention the hoods awesome looks?

I forget what the extra restriction for it is, but it was pretty minimal.

Rob, the restriction for the K&N #25-0880 foam pre-filter is less than 2% (per K&N).



K&N also has another pre-filter available for the cone filter (the part numbers escape me now), a very fine, very thin material used mainly for off-road, sandy conditions... this is said to restrict no more than 8% or 10% air flow (per K&N HOWEVER, as I'm typing this from memory I'm not sure which of the two figures is correct).

I remember reading several times over that the most benefit (largest drop in temps) is realized when towing... or hauling a good load. Then the difference noticed is significant. That makes sense because of the load on the engine. If you're really workin' it and it's truly breathing better, you should see a difference.

jjdiesel is correct! To those of you that have been on this BB for several years... you might remember, Scott stated there was very little EGT effect with the addition of the Psychotty when NOT under heavy tow or hauling heavy loads. Scott NEVER hid this information from anyone. As for fit, Scott designed the Psychotty to have a press fit between the rubber intake hose and the hole in the cowl. If the 4. 5" dia. hole is not made in exactly the correct location per the installation instructions, you WILL experience problems when reinstalling the rubber intake hose.

Forrest, the new air intake you asked about is called Dam Air, designed and fabricated by Doug Hofeldt, maker of the Air Bulldog induction hood. Dam Air is a custom fiberglass air dam incorporating slots centered within the air dam, below the license plate which is used as the air intake point. Four inch ducting runs from the back side of the Dam Air, air inlet to the OE air box. A new aluminum air intake fitting is pop riveted onto the forward, inward facing corner of the OE air box base. Fog lights are also incorporated into Dam Air providing additional lighting as well as awesome looks.



PS: there is absolutely NO WAY water ingestion of the engine can take place with Dam Air..... unless you use your Ram as a submarine.

Bill L. , I knew I heard about the "stealth" pre-filter somewhere before.



Vaughan, My EGT's peaked somewhere between 80 & 90mph, then were coming down - that's why I stopped the test at 95.



Does everyone (besides a few) believe that the cowl is a positive pressure area? That would be the only reason it would be better at higher speeds, right? I might get a gauge here at work and check it - we have gauges that are designed to measure fractions of an Inch of H2O + or -. I could also use that to check the other areas people are pulling air from - this should be a worthwhile test.



I may just keep the 0880 and get one of JRE's heatshields and try that. The 0880 by itself (I tested this before the Psychotty arrived) did almost exactly the same as the K&N in the stock box with the snorkel removed, so it should do a little better with the heat shield. It's worth a try.



Any other ideas?

Junk! what is junk

I would like to know where you come up with your opinion that my product is junk? If my product is junk then my customers are junk buyers. I don;t like the sound of that, if you have good reason for calling my product junk post it here and let I and my customers reply. A lot of people have opinions and they are just like you know what. But up to this point you are the only onethat has that opinion. As alway opinion are welcome even yours.

Thank you

The "Other" style of prefilter K&N makes is similar to the pantyhose idea. Its main purpose is to shed water, not so much dirt. It was mainly desgined for boats or serious mud running. You would be better off with the foam pre filter.
