Red crew cab is taking shape! We need name ideas for the red truck? I'll pin the most liked idea!

[@richardallen1816]

Currently trying to fix up my dad's old "91" 5.9, and your channel has been great for do it yourself person looking to improve or fix up the first gen. You are very effective at showing all the steps you took to fix/make things correctly.

[@decentgarage]

Thanks Richard!

[@blaphtome9382]

For one time fits hand sanitizer makes a great lube for hose and other such fittings. Residue evaporates instead of hanging around accumulating dirt.

[@bobkmac]

2.5 years later and that filter is now $65. All parts total $183. I❤inflation.

[@nmdiesel]

I did the same thing on my first gen years ago with the addition of fabricating an aluminum cold air box/shield. Nice job!

[@decentgarage]

I want to come up with a heat shield as well.

[@HoosierDynamics]

Highly recommend getting a filter wears pre filter to go over your filter. to prevent water damage to the filter. I put one on my Donaldson and it has extended the life 10x further than without it. Highly recommend it. First gens throw tons of water under the hood and the filter sits right at the hood line with the fender which dumps directly into the filter. The pre filter slips over and is 100% water proof and doesn’t restrict any airflow.

[@decentgarage]

Great advice! A few others have mentioned this as well and I'm going to pick one up for sure.

[@2eyedjack433]

I really haven't thought about intakes just yet, still trying to get other things done first. My stock 89 set up i can hit 28 lbs or so if I stand on it. The EGT climbs almost as fast as the boost too. Thanks for another budget project for the working man!

[@decentgarage]

Thanks!

[@grw707]

Did you notice any more noise/spooling? I mean, these trucks are loud enough and I’m not trying to feel like I have a high school referee in the passenger seat but I loooove that spool

[@decentgarage]

Yep definitely can hear the spool better which i really like.

[@drnastey]

Watching you drive to test the filter has made me realize how loud my truck is inside without the carpet or sound deadening

[@PnwTinkerer]

Excellent video, thank you for taking the time to make this. This is exactly what I was looking to do for my first gen! 👍🏻👍🏻

[@decentgarage]

Glad it was helpful!

[@TheRustyGarageandHomestead]

Nice job Tim

[@decentgarage]

Thanks Mike!

[@andrewneilsen1516]

I’ve got a 1990 truck, with the 3” turbo inlet. Just repeat with smaller size? Or you have a better idea?

[@decentgarage]

LOL, funny story... I actually woke up frantically during the middle of the night last night when I realized I didn't address this question! Yes, you will just need to buy a 4" to 3" adapter. I would put the adapter right at the turbo so you have as much 4" air flow as possible.

[@andrewneilsen1516]

@@decentgarage Thank you very much! Love your videos! keep the the great work!

[@jeverich]

Looks good! I've got a similar setup; in fact I'll post a video of my rig on my channel as well. One suggestion; you might want to look into a pre-filter from Outerwears. Now that you've removed the stock airbox, there's really not much preventing your filter from getting waterlogged. Those pre-filters are made from a hydrophobic material. Well worth it!

[@nathenthompson9373]

X2 on the outerwears pre-filter. I use one also and helps a lot to keep the water outer and longer filter life. Great video!

[@decentgarage]

Yep, I just found out about outerwears and I'm going to be getting one for sure.

[@JU57US]

I've seen so many overpriced air intake setups... thanks for doing one that's incredibly effective while being conscientious about budget.

[@decentgarage]

Glad it was helpful!

[@blakebaker6611]

Redline ruby seems like a decent name

[@decentgarage]

I like that!

[@josea.marquezglez4408]

Simple set up and efficient. Love it!

[@decentgarage]

Yeah i works excellent

[@oldcroneysgarage9739]

Clifford the big red dodge....

[@decentgarage]

Great suggestion!

[@TLavery707]

Great video and intake, if you used a different filter you would have had to find another way to mount the stabilizer bracket. Seems like the Fleetguard was the right choice 👍

[@decentgarage]

Great point!

[@NVSRides]

Looks like that would work great. Nice work!

[@decentgarage]

Thanks 👍

[@mitchellmeszaros7658]

You could always drill the hole on the fender slightly larger run the bolt through the bottom and wing nut the top for tooless removal granted the hood would clear

[@decentgarage]

Excellent idea! I'm going to try this for sure!

[@CatheysKid]

I’ve always had a problem with air intake in the engine compartment... to much hot air...my first gen loves cool air...found K&N knock off cone shaped filter and simply adapted it to my stock filter housing. The air outside my engine compartment is always cooler than inside... just a thought.

[@decentgarage]

Good tip! I've heard both ways and heard many knowledgeable people argue each side.

[@Yellow12Valve]

Where did you get that aluminum bracket from?

[@decentgarage]

Just a piece of 3/4" stock aluminum from tractor supply. Sorry I'll add that in the description.

[@iluvducttape1]

Hey thanks for the shout! I like that bracket you made. I'm curious how it does under load, since it's mounted to the body and not the engine. I guess whatever flex is needed will just move at the silicone elbow?

[@decentgarage]

Yeah, any flex will be absorbed by the silicone.

[@iluvducttape1]

@@decentgarage makes sense!

[@franklogan494]

Great Video!! The only problem is, if you want better Air Flow, Upgrade your Intercooler, for your first step for better performance. Air cleaner upgrade's do very little, except make the Producer's of the Product very rich.

[@decentgarage]

This particular truck has a powerstroke ic and 3 inch piping.

[@franklogan494]

@@decentgarage Yes, you have a lot of Great Video's and I have even asked for your advice about your seats. I was only commenting on the Air Cleaner upgrade. Power is all about the ability of the engine to flow the most amount of air, that is the only reason I said that.

[@Pilinchi1]

Hi, I am new to your channel and I like your approach on doing the presentations. Very well done! I have a 1989 6BT non-intercooled engine that I installed in an old bus (1956 Western Flyer 4x4) and it's connected to a Allison 545. I have the stock D250 harness but I want to convert it to a bare minimum harness to run the Bus, feed the alternator and have the manifold heater. Do you have any suggestion on how to go by doing this? Should I modify the existing harness or should I start with a new harness? Thanks!!

[@topfuelr473]

My truck has never seen over 24LBS of boost. I'll have to try that filter.

[@decentgarage]

Stock H1C? That's good for an H1C. The turbo is this video is a super bee and I'm honestly not impressed. It takes forever to spool.

[@kaydewhipple7696]

@@decentgarage the super b turbo will have a lot larger turbine wheel than stock idk what series your p pump is if it's a 160 pump or a 180 ect. But timing and fuel will help greatly and living at elevation in the more timing will hurt spool as well . I have a set.of 6x11 injectors laying around that would compliment that turbo well and maybe a afc spring.

[@topfuelr473]

@@decentgarage yes, stock H1C with the banks upgrade.

[@decentgarage]

@@kaydewhipple7696 I believe the pump is the 180 (97 automatic). Supposedly the injectors are 50 horse which I don't know what size that is. I really want to get this truck tuned better.

[@bryank5932]

Bhaf will slip right in to the factory rubber elbow going to the airbox. At least on my 91.5 it does.

[@decentgarage]

Interesting. I didn't know that

[@Vanisl4runner1]

What’s that filter like compared to stock??

[@decentgarage]

Much better flow and better filtration

[@redlined9192]

Genos sells a different part number fkeetguard for 33$ I wonder if it flows as much air though

[@decentgarage]

It might be fine. This one was recommended by someone i highly resoect in the cummins world so I trust it

[@jamesbush268]

Like the video. Question, when you swap in a 12 valve, does the motor mounts change location much?

[@decentgarage]

No, motor mounts are the same.

[@reallyaintbuynit2018]

Anytime you are attaching aluminum to steel use Stainless for your attaching hardware. Aluminum will cause electrolysis and eat the steel. Plastic grommets aren't a bad idea either.

[@decentgarage]

Interesting. I'll make sure I get some stainless hardware on there for sure

[@aaroncliffton8621]

Will this work on the Non I/C turbo trucks as well?

[@decentgarage]

It will but if I'm not mistaken the inlet on the non ic h1c is smaller then the ic one.

[@decentgarage]

So I would verify the measurements an then order the parts accordingly. If it is smaller you may have to get an adapter

[@johna7184]

Is that the OE filter?

[@xc8487]

There's a pic somewhere of an air box made from a stock pot. Never really good to have an open filter in the bay, it gets hot and dirty fast.

[@decentgarage]

Yes, this is an idea brought up from an old write-up on cummins forum. I may try it at some point.

[@benmichel982]

What size rubber hose did you use in this video?

[@decentgarage]

4" with a 45 degree bend

[@317808941]

Am I missing the parts list someplace? Thank you!

[@decentgarage]

Should be right in the description box of the video.

[@317808941]

I needed to tap that chevron, thanks!

[@KeystoneOutdoorsman]

You may have already addressed this in the video but I didnt catch it, what size silicon boot did you use? I have a 91 non intercooled stock turbo. I have a brand new AFE air filter 4" laying in my garage that I never put on my 3rd gen when I had it.

[@decentgarage]

For a non IC I believe the turbo has a 3" so you will need a 3" to 4" coupler which I would put as close to the turbo as you can.

[@KeystoneOutdoorsman]

@@decentgarage thank you for the reply! Happy New Year

[@blakebaker6611]

What’s turbo setup? Definitely not stock lol

[@decentgarage]

BD Power Super bee

[@johna7184]

How much louder is it?

[@Really-AintBuyn-nit]

Attaching aluminum to steel=electrolysis. I would use nylon washers and stainless hardware. Any contact points will rot. Especially if you introduce road salt into the equation.

[@decentgarage]

Thanks for the tips!

[@mattsoucy1506]

What is the correct size silicon elbos for the h1c? Largest available on the link is 3.5" is that used with the 4" aluminim?

[@decentgarage]

You need a 4". I just updated the description with a new link to a 4" 45 degree elbow.

[@mattsoucy1506]

Thanks a lot! Thanks for your videos. The 4" should fit with the h1c no problem?

[@micahgood5691]

Is that filter reusable?

[@decentgarage]

No, i would recommend and outerwear pre filter which I have also linked in the description. In my mind I'd rather have a filter with better filtration that i have to replace every 15k miles than have a reusable filter that doesn't filter as well and have to worry about ruining a turbo or other things.

[@04sweaty]

I can't find this on Amazon. Can you send me some info on how to find it? Thanks.

[@decentgarage]

The links for everything needed should be in the description of the video.

[@cosanostra4286]

I don't see the link

[@lkrux]

Slap a filter wears prefilter on it and itll also be waterproof

[@decentgarage]

Yep, i added that to the links in the description. Thanks for the suggestion.

[@wesscarey4475]

If water was to get on the filter while driving it could be the end of the engine.
