Need some pointers here. Ive read about some of you making your own open air style filters. Im going to make one for my 95 psd this weekend. I know I need a stainless steel elbow, and some hose clamps. But what about the filter? Is there a specifc one I need for this kind of setup? Any info on this subject would be greatly appreciated.

Just installed the 10 k mod this afternoon. Very pleased with the results. You guys were right, once you start you cant stop with these machines.

 

If you're looking for the big paper filter it's a Baldwin pa2818, or napa 6637. There is a recent thread that has all the cross reference part numbers listed. If you prefer an oiled gauze filter, then anything with a 4" neck will fit.

 

When you do this Modification be advised… You will experience the most horrific “Belt Squeal, Turbo Flutter, Cat Stuck in a blender, Whine” you can stand. In short, when you’re on the gas or let off the gas the turbo will “Whine or Flutter” and it is amplified X-Fold through the modification. I personally find it annoying as HECK… Just my thoughts..

 

Some love the sound, some hate it. Personally, I really love it, especially running on the Interstate. Your '95 will be easier than the intercooled PSDs, you've got much more room. Go to webshots.com and search for "Tymar". You will find alot of info and pics.

 

I bought a K&N cone filter, and used it.

 

all the dimensions are the same for the following filters and Napa or any other auto store ought to be able to get a cross reference from any of these numbers:

Napa # 6637 (the website this comes up as a spark plug, but
in the store they can get it right for you)
Fleetguard # AH1141
Donaldson # ECB085011 the guys in my area go by B085011
Baldwin # PA2818
Purolator # A45090
Cummins # 3912020

hope this helps.

 

You should have saved your money and bought a filter that won't let in dust.

 

Thanks, that's what I was thinking, but just kept my mouth shut.

 

Thanks for all the replies. I will be making it this weekend, let you all now how it goes.. And wether or not I like the "turbo flutter".

 

OK, so why do you get this "turbo flutter" with a different filter?

 

There is much less restriction, so air flows a lot more freely. I already didn't have a muffler when I got the Tymar intake and it made a noticeable difference. I don't know why it bothers some people, it doesn't bother me at all.

 

john....I'm intrested in knowing how long ( years and miles) you have had your Tymar on. I like knowing my engine is getting more aire and I rest much easier knowing that unfiltered air cannot get to my engine now. What I am concerned about is the turbo...I have done alot of reading on here and other site (ie: diesel stop, etc) about the surge/stall problem. I am convinced the loud squeal/belt sound/static sound/annoying noise/etc that I hear when the truck shifts from a lower gear into overdrive and the tach goes from 3k to 2k is bad. I have read, even on this site that it happened with the original airbox, but because of its construction you just couldn't hear it. I don't know about this. with the hugh increase in air backing up thru the turbo due to the drop in RPM's, does this not have an adverse affect on the turbo and its bearings? I can get over the sound if I am sure that I'm not sacrificing the life of my turbo because of the air forced back thru from the manifold. Even if it did do this with the stock airbox, the amount of air being forced back thru the turbo wouldn't have been as great would it? This being the case, it might not hurt the turbo as much as the increased air flow of the tymar? what do you think?

 

Fisher-

Don't worry yourself so much. Think about the way a turbo works. All you are hearing is the sudden spool-down of the turbo. When your engine shifts from overdrive, the drop in RPMs drops the exhaust gas, thus dropping the turbo speed. You are not backing in any excess pressure, the manifold pressure is dropped. I don't know if you are running a boost gauge, but on my truck for example, this sound corresponds to a 5-8psi drop under normal driving conditions. You are not hurting anything, just sit back and enjoy the sound!

 

phat...I want to believe you...but that air that the turbo just sucked in and then no longer needs so much of it has to go somewhere...and from all I've read its back out the turbo.

from what I have read and understand it works like this the turbo sucks in the air. the more the turbo is used, the more air it sucks in. So...the higher the rpm, the higher the turbo, the more the need for more air coming in....when the truck shifts into OD, the rpms decrease, the turbo isn't sucking in the air, but instead the built up air that is no longer being used and can't be contained is instead forced back out of the turbo..then the turbo starts sucking the air back in again....my concern is this sucking in and then forcing back out is rough on the turbo and in all reality eventually will do it in.

the same thing may have happened with the stock box, but it was on a much lesser scale than with the tymar (due to the hugh increase in airflow).....since it was happening, but on such a smaller scale I'm not sure that it was hurting the turbo like it might be now....

I'm not saying the tymar is bad...I'm not saying the noise is bad...I just want to understand this better and know that while I'm providing my truck with cleaner air and better filtering and even more air, that I'm not hurting the turbo in doing so...the air has to go somewhere when it shifts into OD.
