Instead of having multiple threads on the same topic, I have merged most of them with this one. Please use this thread for any tymar comments.

I have been looking into a greater gain intake of some sort, and references to the TYMAR intake keep cropping up. I looked into the beast, with research of pictures and installation and came up with a couple of questions.

First question has to do with the diesels' love of cool air getting to the intake. The TYMAR does not seem to accomodate this, by having no ducting to keep the warm to hot engine temps away from the filter. Therefore, how does this system benefit the engine? I would assume that any benifit in breathability would be offset by the amount of heat present at the intake.

Second question. Should the heat be a negative factor, as I assume, has anyone fabricated anything to counteract the heat?

The questions promote others, concerning intake temps, and the first of these is.. Are there any particularly effective intake systems that draw cool air from the front or outside of the engine compartment, that give significant gains?

next.. Does anyone make a system that could be ported through the hood, to get cool air from above?

The intake system in my truck is the nearest thing to stock in the whole truck, so needs to be addressed immediately.

Hey Theo,

There are some respected sponsors on this site that have conducted tests using two t-stats(one in the engine compartment and one in the wheel well) and have found that temps do not vary more than 20*. If you look through that thread you'll find it Here is Link of my home made "Tymar" style filter. Great mod for $40.00. Western Diesel makes a "Ram Air" setup but I haven't heard much good response about them.

 

I'm getting ready to go out and install my homemade Tymar. I also bought a piece of 4" Flex Ppe from the heat & air dept. at Lowes that I plan to run fom the grill to the filter.

pcwirepro; I saw your photos on another site and if I remember right, your filter is a Napa. I bought the exact same filter only it's a Wix. Part # 46637. I guess the same folks make them all.

 

Bull,

Where do you install the flex pipe? Is it smooth inside, unlike the factory tube?

 

The open elements flow vastly superior volumes, and by the time it's through the intercooler, it's pretty close to the same temp anyways.

Yes. I put a hole in the plastic radiator support, and ran some tubing along the inner fender exiting below the filter.

I think T/S performance sells a functional ram air hood.

 

Thank you for the link, it raised more thoughts though.

It would appear that consensus of opinion given by respected persons familiar with the Powerstroke engine, that colder air is much better than masses of hot air, but the consensus of opinion with those not professionally involved with making performance modifications of the Powerstroke assure us all that the reality is more air is better, notwithstanding the temperature.

From this am I to assume that the rank and file know more than Gale Banks, a person whose company helped build my truck. I do not think so.

My questions are answered, guys, and I thank you for that - my stock system would seem to be better than any drawing air from the engine bay. Cool. Now all I have to do is figure out how to improve on it considerably. That is the only thing wrong with questions such as this - There are complex arguments for every side, leaving the uninformed totally confused. Fortunately, I have met Gale Banks, and trust his work, his company and his opinions, so he says don't get air from the engine bay... That is good enough for me.

Western diesel is not well enough reputed for me to want their efforts in Ram Air, is there anyone else out there doing anything in that direction?

At idle while stopped the air is only about 20 degrees hotter that goes into the engine. The decreased restriction does offset this temperature. While driving, the cool air that is forced under the hood is what will go into the intake, just like a stock setup does. The Tymar outperforms and outfilters all of the other setups on the market so I would not recommend anything but the Tymar.

 

Volant also makes a higher end "ram air" style assy.

 

About how much does a tymar intake setup cost?

 

Are you kidding? Tell ya' what, get a nice cheap open air system like this one drive it for a week, and if you don't like it I'll buy it from you.

No I don't work for them, nor do I have a single item of theirs on my truck. I do however know that no matter what Gale Banks says, he is not running any little panel filter in any of his vehicles. He is in business to make money to build race vehicles to make more money.

Not trying to flame you or start another filtration war. All I'm saying is try it, you'll like it.

 

I tried to go to the site but it doesnt exist

 

No it dosen't, but the e-mail address and phone on the page are good ones.

 

$40.00 if you do it yourself. Here is a Link to my setup. Look in the "truck" album. E-mail me if you need part numbers.

 

Theo,

I know you have made up your mind but cookie is right. Many of us have had it both ways. I can speak from experience when I say "there are noticable gains." If you build your own for $40.00 and try it for a week you can always go back. Not sure how your stock box is set up but I can get back to stock in 15 minutes.

I also doubt that the infamous Mr. Banks is running any factory filter setups.

 

If someone did that test and represented themselves as a sponsor then they aren't telling the truth. Who are these "sponsors"?
