DIY Tymar Air filter system

[Diezel Dawg]

Jake, have u seen a complete a TYMAR intake??? Does your DIY include everything that a TYMAR does? There is more to Dales kit than a 45* 4' piece of exhaust tube, a filter and an intake boot.

...I've only seen from photos.

Mine has a polished 4" pipe from the turbo to Donaldson filter with clamp to pipe, and a clamp to the engine compartment to prevent chaffing.

More importantly, my setup gets the exact air filtration yours does, with the same airflow.

What does your intake do better than mine (especially when it is the same filter)?
What more should an intake do?
Will my engine notice the difference between a Tymar and a DIY?

It would be better to compare Tymar to the other commercial products. I'd buy a Tymar over the other choices. Great quality, efficiency, performance, and better price.

FWIW,

I worked with Dale in the design of the Commerical Tymar you saw in the previous pictures. Dale made about 90 kits for me about 8 yrs ago. At work(large construction company) we were losing 7.3L engines at an alarming rate. The stock filters in some of the dusty applications were only lasting a couple of days and then they'd be plugged. Anyone that had a 7.3L with some of the early airbox designs, including the infamous fender sucker, knows when a filter plugs up it get sucked into intake, and bye bye turbo then engine if its not caught soon enough. We had a lot of drivers that NO habla English, so explaining to them you have to watch the filter indicator was of no use....come to think of it, we had the same problem with the gringos...Anyway there were a few things that were a must have over the DIY style. We needed the filter kit to be tough and tested, and by that I mean, it had to mounted to the truck. This helped with the bouncing and beating the truck took, and kept the filter firmly in place. Dale also had the main filter body mounting clamp set up, with a modifications so the filter is slightly elevated and lined up the intake tube better.(look in the picture, its not just a standard off the shelf filter clamp, its been cut, welded and powder coated) The ones sitting on the fender and moving around weren’t going to cut it. We also used a different intake tube, this lined up with the 45 deg pipe better. However Dales 4" pipe is not 45 deg, he had them custom bent so the black tube from the CCV bulkhead lined up with the filter. This meant there weren’t any bends it at all. This also allowed the black tube to be at a natural state, and not in a bent-made-to-fit position that the factory one is when you DIY. This helped to make sure the tube stayed put, even if a clamp came loose. We've had great success with them. We haven’t lost a engine to dust/dirt since we installed the filter kits, and most 95% of the trucks go all year on one filter.

My point, is DIY is fine for some people. To each his own. It is after all in some cases the same filter(when it’s a Donaldson), which is way better than the Factory ones.

That being said dale's "overpriced" kit is not just a few off the shelf parts thrown together. There was allot of time and testing that went on, and like I said some of his parts he makes himself....what that worth? $165? It is to me.

Jake, im not saying the TYMAR Filters better or flows more than what u have, especially if you are getting the SAME Donaldson Filter that Dale sells. But if u think Dales kit is just a filter and 45* pipe and a couple clamps, then u are mistaken. Jeremy described Dales kit very well. Jeremy is correct that Dales pipe from the filter to the intake tube is not 45*. There is also a clamp built into the battery tray that comes with this kit that wraps around the main body of the filter to eliminate/minimize vibration. Also, Dales kit allows for his coolant filter system to be mounted on his intake KIT.

If your DIY kit works for you, then thats great. Too each their own with any intake system anyone buys or puts together themselves. One thing i do want to say is alot of people call their DIY intakes a DIY TYMAR. If it was a DIY TYMAR, then it would have EVERYTHING that Dales kit has. But if it doesnt, then it is only called a DIY Intake.

Very well said Jeremy.

If Dale's kit costs $200 it would be competing directly with the Ford Severe Duty AIS and I can't imagine it fits or works better than a system.

For little $$ the DIY Tymar seems like the logical choice.

If you were going to pay in the $200 range for an intake I would recommend the Ford Severe Duty AIS (Delivered to my door for $216.20, click the link in my sig). From what I have read, the Ford AIS is a well designed and thouroughly tested system that flows as well or better than the Donaldson and Tymar filters and was designed for severe dusty desert situations. It also retains full use of the stock filter idicator, air temperature sensor and it looks and fits as if it came from the factory (cuz it was).

If $$ was not a concern I would go with the AFE Stage II w/ProGuard for around $500, as I understand it, this flows the best with great filtration.

Old thread I know but I stopped by Pep boys today and they had everything needed, a nice shiny 4" 45* and perfect sized 4" piece plus the coupling.
All that and a 6637 filter and its done.

[mtnxtreme]

Does anyone know if this works on the E350 van will it fit?

Question:

Does anyone know if the oil returning from the CCV actually help the turbo in any way. I am currently in the process of completely replacing the intake with S.S. from the turbo to the 6637 filter. I was looking at using guzzler's CCV removal to save the rubber intake boats leading into the heads as some ppl have shown problems with the oil coming through the turbo and causing leaks in the rubber as well as making the intake boats covered in an oily mess. This would also make it easier when removing the rubber intake boats with SS to avoid cutting a slot for the CCV vent.

Also has anyone tried using exhaust flex pipe for the intake? good flow characteristics, rigid to hold the light filter in position and easy to manage instead of using multiple bends of normal exhaust pipe. just a thought.

Thanks for the knowledge
