DIY intake

[addicted]

I did a small search offline and couldn't really find anything.

On they tymar DIY Intake what is the filter rating of the media. I don't even know what stock is. I've had the truck for awhile about a year and a half and don't plan on doing a ton to it. I just ordered an magnaflow exhaust and will do this Tymar as soon as the filter comes in next week.

Basicaly I just want to make sure it is filtering down to a level that is nothing I should worry about. I mean does it get its extra flow becuase it filters less particles.....becuase of a better design with less constriction...or becuase it has a larger surface area. I guess I shouldn't really worry to much though. If I was really worried I would have never converted to WVO haha. Hoping to get more out of this truck than my Mercedes....and that is hard to beat...currently at 300K on the car and 187K on the truck.

Ohh by the way it is the conical filter 46637 or 6637 at napa.

First off ... ...on convincing the wife to let you keep your truck.

I wouldn't be concerned with the Tymar setup. For CFM specs check the Donaldson website (P/N B085011) or Baldwin's site (P/N PA 2818). Compared to the stock or K&N setups, the Tymar has a better seal to keep out unfiltered air.

haha
Thanks Hey Now....it has been good times now that I get to keep the truck. Can actually ***waste*** a few bucks on here.

I'll check out those sites and see what I can find. I've read many debates on the K&N filters about how they let a lot of stuff by yet tons of people run them. So if this is better than that is good enough for me.

By the way you'll all be seeing more of me soon. I think T wildman might be getting a call around spring

I will be buiding that air intake next week, and I got a cheap magnaflow SS Turbo back on Flea-bay that should be here next week to and I hope to hang that up. Lastly I got a 3 guage pillar and boost, tranny, pryo on the way. I I want to get some readings from those before I install the intake and exhaust to see what type of difference they make.

It is like a belated Christmas around here.

I changed the name of your thread title out of respect to Dale, the founder and creator of the Tymar intake.

On to your question, the Napa, Donaldson or Baldwin filter flows more air simply due to size and material construction. Its a big ole huge pleated paper filter. I dont know the micron rating right off the top of my head but........... I have seen the flow test data on the pleated paper filters over what a cotton gauze filter (KN style) or stock air box with drop in filter can and will pass and the pleated filter wins hands down. Both in flow and filtration. Rest assured knowing that the 6637 isnt letting dirt into your engine.

Thanks 95 Stroker... I wondered why it was called tymar DIY on other threads. I see why now. I noticed his site was down so couldn't really compare.

Happy to know it filters well.

 

[95_stroker]

He has never really had a "site" other than an e-mail addy and a phone number. Dale is a helluva nice guy who offers more than just air filter kits. Dont bother with e-mail but I would encourage you to give him a call if you really really want to talk to someone who knows a TON about the 7.3 PSD. Hes a really good guy. Give him a call sometime, you wont be disappointed.

Will do

Here is another question.

I was just reading on another post about split shot injectors as when I was talking with someone back in Portland he thought I had them as my truck sounded so quiet. He didn't know how to check though.

I just went out and looked for spaceship enterprise and there it was much to my very happy surprise.

So from what I know and read on the one post that mentioned them was that they came in late model 97's. Was this only a Cali thing for emeissions. My truck came from just over the border in Medford OR so it wouldn't surprise me if it came from Cali originally.

But I guess what I want to know is 2 things really.

#1: If stock Injectors can push about 75HP what can the Split shots push in terms of HP. Also how much fuel do they push out in CC in comparison to the stock.

#2: Does this mean these have different PCM's as well. Is it necessary to mention this when getting a burn.

Edit: I just found this but doesn't say much http://www.intellidog.com/dieselmann/injector.htm

To answer your questions;

1. I *think* stock single shots were good for about 100cc's max and Split Shots were good for about 120cc's of fuel delivery. I hope that someone will come in behind me and correct me if I am wrong. The thing to remember about split shots is that they they came into being for two reasons, first and foremost was emissions related. You get a small pilot shot of fuel about 8° to 10° prior to getting the rest of the fuel, hence "split shot" and what this did was lowered particulate emissions and lowered NOX emissions, a side benefit of the splits was it lowered combustion chamber noise (diesel rattle).

Drawbacks to the splits are that they have a longer injection time because the injection cycle is split into two seperate functions, they also consume more high pressure oil to operate. Guys looking for bigger horsepower are going after the single shots because you can get more fuel in faster and consume less HPO in doing so. Downside is lotza smoke and NOX and noisier engine operation. Pick you poison.

#2. Yes, different PCM codes are used to operate the different injectos and your programmer needs to know what year your truck is and what injectors you have.

Here is a real good write up on the HEUI injection system.

Thanks that was some very good reading.

I understand everything that was mentioned but I do have one question and maybe my understanding of Thermal Dynamics is missing a key theory.

Why would guys not be going for the Split Shots if they can deliver more fuel. You mention single shots becuase they can get more fuel in faster, but is Power not a direct function of the amount of fuel (BTU) burned? If you can burn just under 20% more fuel out of the Split shots should you not be able to get more power. And on top of that you have less **smoke** unburned fuel thus a higer percentage of that total fuel burned anyway.

I think I see where the draw back is with the High Pressure Oil delivery to all of the injectors. I remember reading an article about a High Pressure Oil Crossover. I assume this helps give more oil to the other side of the cyclinders and helps maintain high pressure during hard acceleration.

Also I saw the acronym HPOP often but never a description. Intuition now leads me to beleive that this may be a High Pressure Oil Pump. Is this so???

If that is the case it would seem one of those may allow for more power/fuel to flow from the injectors. I also assume though that those are very very expensive.

Thanks again, When I get off work I have some more research to do.

Addicted, What color is your engine block...black or blue? If painted blue and around your turbo pedestal/fuel pump is a "flying saucer" disc gizmo, I believe yours is a California emission engine with split shots. If painted black it's a 49 state federal with single shot injectors.
