First Gen Cummins with marine 370's and an HX35

[@PalmerBoudreau]

"sounds more like a diesel" lol I thought a first gen cummins was the most diesel sounding you could get ha ha

[@themadmailler]

Palmer Boudreau I know it sounds odd, but with the older injectors the exhaust had a more gargle-y and throaty sound. more like an old industrial diesel, like an old caterpillar or Murphy diesel. the new injectors gave it more of that classic diesel "knock". i assume it's because all the cracking pressures are alike and up to spec and they are in general better condition.

[@PalmerBoudreau]

yeah I'm watching the intercooler install right now. Smart thinking the way you supported the frame.

[@themadmailler]

Thanks!

[@AmericanThunder]

@@themadmailler The injector change will alter the injection timing, too, which can really change the sound.

[@danisyx5804]

My 96 sounds like a f****** dump truck I'm inclined to agree with you The only thing missing is an engine brake

[@bobbybearclaw]

good lord allmighty take a look at those cab lights!!!! awesome!!!

[@themadmailler]

thanks bud! they were installed by one of the previous owners. they were taken off of a peterbilt.

[@bobbybearclaw]

Love it. I'm building my 1997 F350 with a 1991 Cummins and had no idea what to do with my intake tube untill I saw your video.........thanks abunch.

[@themadmailler]

glad i could help! keep in mind that this set up works great, but can get things hot if you're pulling a trailer a lot. eventually i'll install an intercooler.

[@philipraats4167]

nice work dude, I'm working on my first gen cummins right now. just grinding the frame, box, and anything else rusty at this point. just got the gas tank out. it was surprisingly about 60% full to my delight. it has been sitting for six years, but i heard her fire up before i bought her 6 weeks ago.

[@Sproutt]

stock air box is truly the cold air intake... that filter ( cold airbintake style) is getting its air from inside the engine compartment would mean that your getting warm air not the "coldest possible incoming outside air"

[@UnitCrane514]

That sounds awesome! That idle doesn't sound bad at all, I have heard WAY worse! 😊

[@themadmailler]

thanks! it sure does sound sweet at idle. much different from before.

[@tommymartin7141]

Beautiful Cab lights 😃

[@themadmailler]

+Tommy Martin Thanks! one of the previous owners installed them, i believe they are off a Peterbilt.

[@SootyMangabey.]

Played that startup sound at least 50 times... cant wait to p pump my 24 valve

[@awashbowler]

If Im not mistaken... the marine injectors have a spray pattern that is only compatable with marine cummins pistons and their bowls. Not saying that they dont work with normal over the road pistons as they obviously do but when it comes down to the hard numbers a, if you matched your injectors to a set of marine pistons youll see better hp gains and better fuel economy and efficiency.

[@themadmailler]

+Austin Washburn technically, you are correct. However, marine 370's have a 5X12 nozzle, and these injectors also have a 5X12 nozzle, but in a spray angle (i think 145 degrees) compatible with my non-intercooled pistons. They are custom injectors built by TheHungryDiesel.

[@pineintheash6707]

hi there , i appreciate your detailed videos. i have a stock 91 non ic with a bhaf and 4" exhaust. i want to add a stage one fuel pin,3200 spring and 16 cm housing. should i be worried about egts?

[@themadmailler]

+pineintheash any time that you do mods, especially on a non-IC, you should install a pyrometer to monitor temps. The set up that i have in this video made 900-1200 degree temp just gunning it up an entrance ramp, empty. See my other videos for how i installed a second gen IC, it cooled it off very well.

[@systemfile]

I’m wanting to put new injectors in a 91. If I got with those marine injectors do I need to do anything to the stock injection pump?

[@themadmailler]

no, but a new AFC slide pin is cheap and couldn't hurt.

[@LusiTron]

Love how the outside is shit, but then you show the engine, and then, it's all worth it...

[@Jordy40Growing]

use the idle adjustment screw

[@themadmailler]

yep. i heard the locknut was a pain to access so i didn't even bother. i'll do it the "right" way soon!

[@HAYSE557]

you can loosen the throttle linkage to adjust throttle takes 5 min max

[@79snickers]

sounds really awesome so does the turbo looks nice besides the rust

[@scottmiller7017]

Where did you order the 2 piece cross pipe system from. I have looked everywhere? HELP

[@themadmailler]

I made it from exhaust tubing.

[@michaeljp86]

Is that little chain from a toilet tank?

[@themadmailler]

+michaeljp86 I just have rolls of the stuff in my shop.

[@erwin643]

MOTHER OF GOD NOOOO!! On top of an exposed air filter under the hood (sorry kids, the hot air coming in from the engine compartment negates any advantage of exposing a filter under the hood. Dodge, apart from their other fuckups back then, actually had a good rubberized plastic air intake for the first gens), no intercooler!! This means that the intake air between the turbo and the intake manifold is being pre-heated (again!!) by the engine!! Gale Banks himself would have a heart attack!! You've got multiple heat generators heating the air going into your engine (air filter, turbo, then engine)!! What I would do: Re-install the factory air filter setup. Then wrap the intake horn going over the top of the engine with lava rock tape (works both ways to keep heat out).

[@themadmailler]

I made that crossover tube, but the original was identical. The intake isn't great but it's how it was when i got the truck, so I just ran it. not ideal but at least it was sucking air from the front corner, away from the radiator.

[@MYsequinedsky]

smart temporary fix - chain on throttle

[@danielchampagne8965]

Did you have to use the exhaust manifold from a 2nd gen 5.9 for the turbo, and where did you find the oil line adapter for the turbo?

[@themadmailler]

+Daniel Champagne the manifold is the same, and i got the oil line adapter off Ebay. It was about $8.

[@Andrew-qf6sd]

Do you have any sites you got the mandrel tubing from? I'm looking to put a hx35 on my 90 non ic truck, gonna have to basically do the same set up you have for piping would love to know how it was done

[@themadmailler]

I bought it all from ebay. However, I would strongly recommend an intercooler swap with that set up. a 2nd gen IC fits pretty well, see my other videos for details on the install!

[@Andrew-qf6sd]

+themadmailler yeah I looked into it I'm gonna do the Intercooler with hx35 but I'm having trouble figuring out how this turbos outlet is gonna line up with the Intercooled pipes. The exhaust flange mounted seems like the turbo outlet where he crossover pipe would be has to be moved downward cause it would be positioned straight up. Is there a way of rotating it?

[@themadmailler]

yes, you can rotate the compressor housing by squeezing the large snap ring that is behind it. your best bet is buying a number of 3" mandrel bends and straights and a number of 3" boots (i like the hump boots for more flex). then you just piece it together one bit at a time. You'll need special boots to go on the intercooler in/outlets, they are a goofy size.

[@russellinscho6960]

where did you get the adapter from? also where can i find that turbo. looking for a new turbo for my 1991 d250.

[@themadmailler]

got the turbo on ebay for $375 used. and what adapter? cold side outlet i assume you mean? it's a 2 1/2" v-band flange, carbon steel. i just welded it to the tube. thanks for watching!

[@hunterlong1266]

Video just started and I heard new clutch and transmission

[@marcuswarner7052]

Do you still have the old crossover set-up? I just got an HX35 for my '89 and would be interested in it if you were willing to sell.

[@gaetan458]

Hello. You look like you know what you doing on old dodge diesel. I have questions that you might be able to answer about them truck. l own a W350 automatic w/overdrive 4x4 diesel with original 15,000 miles on it. Bought 2 years ago with only 7,000 miles. The only problem that I have with it, is there is not enough hp from its original 160 hp. My question is with all the modifications you have done on your pomp & turbo how much more approximately hp do you get? I would like a the very least double my hp (320) but between 400 & 500 hp would be nice to have. Well put it that way, how much more horse power you think I could get with a reasonable expense and most important keep the truck reliable and safe to drive. Let's not consider the poor transmission has I would modify it, according to the hp of the engine.

[@themadmailler]

Gaetan Giroux 1)First off, if you're interested in modding your truck, do lots of research on your own to get an idea of what's out there. CumminsForum and DieselTruckResource are two good sources of data. 2)If you're gonna mod, make your first mod a set of gauges to monitor EGT, boost, etc. that way you won't fry your truck. 3) my truck after i finish the current mods (see my other vids) will likely produce between 200-300 horse, depending on pump tuning. 4) these motors are not capable of producing much more than 400HP, some people have achieved 4-500HP with nitrous, water/meth, and LOTS of other mods. 5) IMO unless you want bragging rights it's not worth it. these are old diesels, not muscle cars. they are also not gassers and don't need gobs of HP to be fun. just after the mods i did in this video, the truck was SUPER fun to drive. I can't wait to see what it's like after the other mods i've installed.6) have fun!

[@gaetan458]

themadmailler thank you for your out put. Can wait to see what next you'll be doing on your truck. And thumbs up on the way you explaining things.

[@themadmailler]

Thank you! good luck and have fun.

[@nonagreeable]

What's that red thing called that goes to the turbo with the boot connecting them? I see them on some 1st Gens but never 2nd Gens

[@themadmailler]

it's the crossover tube. you don't see them on newer 1st gens and 2nd gens because they all have intercoolers, which routes the tube in a different direction through the cooler.

[@Mr.Beastforpresident]

NICE!!!! How's the acceleration with no intercooler? What's the hwy Mpg?

[@themadmailler]

IC doesn't affect acceleration, just EGT's. No idea on mileage - when i first got the truck with 200K and stock everything, it got about 18mpg.

[@madmatmotosport6806]

when you got the marines did you get a set of after market ones with the 145* spray pattern or are they true marines 155*

[@themadmailler]

+matthew roach I can't remember the angle but they are correct for the non-IC'd pistons. Talk to Eric at TheHungryDiesel, he can help you out.

[@BrodieBr0]

Lovely truck! My 1990 is a dark blue/ light blue combo in bad need of a paint job. hahaha I know this is an older video, do you still have the truck today?

[@themadmailler]

Sold it about a year ago, replaced it with a 2002 Cummins dually ext cab 4x4 6 speed.

[@BrodieBr0]

@@themadmailler Ah nice, a Cummins for a Cummins..you win that deal both ways. haha

[@yamamerjohnson3115]

When you upgraded your injectors, did you have to upgrade the lift pump too? Or can the stock one support the new injectors? Also what would you estimate the power your truck is making? Thanks!

[@themadmailler]

i would guess about 200hp. upgrading lift pump is always a good idea, but if the stock one can't keep up the injection pump has it's own vane pump inside to suck fuel. it's not good to run it that way but it will do it.

[@yamamerjohnson3115]

themadmailler sounds good man I appreciate you’re help. I currently have a 01 f350 i swapped a 6bta from a school bus in. Its practically just an aftercooled first gen motor. I used an hy35 turbo i had laying around, and i plan on going 5x14 injectors. If i turn the fuel screw maybe like 3 turns and turn the boost up on my turbo, is it realistic to expect around 300hp? Or am I delusional? 😂 thanks again

[@themadmailler]

No idea, and it's not as easy as just cranking in some screws and going for it. it's something you have to play with for a while. and be careful with that fuel screw, 3 turns might get you into a runaway situation. I wasn't able to turn my screw in much without getting RPM hang, which is annoying and also lets you know that you're close to runaway. also keep boost around 30psi max, i don't think those turbos are very happy above that.

[@yamamerjohnson3115]

themadmailler alright buddyy, thanks for letting me know! I guess there’s only one way to find out haha and 30psi is what im shooting for

[@themadmailler]

Good luck and have fun!

[@vwkaferman]

First Gen owner here as well; Why wouldn't you just adjust the idle on the VE-Pump? I mean, it's right there? No reason for some hokey chain. That's crazy. Keep on truckin otherwise.

[@popo_53]

High production value

[@nicktrevino2911]

Do u have the part no for that oil fitting

[@themadmailler]

no i don't, i got it on ebay. A little google searching and you should be able to track it down.

[@drewgrob6346]

Where did you get all the piping ?

[@themadmailler]

they are mandrel bent pieces of exhaust tubing i bought off ebay.

[@ESTuners]

No way you left it un intercooled? Nice

[@themadmailler]

I eventually added an intercooler. I have some videos of the install!

[@alonzo5800]

was that exhaust bought or did you make it?

[@themadmailler]

+AlT-Gaming purchased by a previous owner. all the diesel websites have 4" downpipes or full exhausts if thats what you're looking for.

[@alonzo5800]

+themadmailler i need to get the rear brakes done and would like to replace the booster and all, would you suggest me doing it myself or going to a shop. Im not super knowledgeable or experienced but would like to learn how to do that kind of stuff. thanks :)

[@themadmailler]

Do it yourself. it's easier than you think! shops rake you over the coals, give you sub-par parts and workmanship, and charge you as if they gold-plated everything.

[@alonzo5800]

alright, thank you!!!

[@scottedenfield9150]

Do you have the pump turned up at all?

[@themadmailler]

Not at the time of this video. take a look at my recent videos of this truck to see what i'm doing to it... it will get some pump tuning in the near future.

[@ivansolis2465]

Give the number parts I got the same truck I need to install that on mine

[@RJPatt]

p7100 injection pump?

[@themadmailler]

+R. James Patterson Skene bosch ve6. the p7100's came on the 2nd gen's.

[@1stgenclub619]

Where did you get that intake system at?

[@themadmailler]

I made it myself using mandrel bent exhaust tubing.

[@1stgenclub619]

Ok

[@1stgenclub619]

themadmailler what about the air intake?

[@themadmailler]

@@1stgenclub619 That was on there when I bought the truck, but i put an Amsoil filter on it.

[@1stgenclub619]

themadmailler oh ok

[@David_TX]

Where did you get your injectors from?

[@themadmailler]

thehungrydiesel.com it ended up being a little under $600 for the set, because i had to get the copper spacer washers to adapt the narrower intercooled style first gen injectors into my larger non-IC head. make sure you get the correct spray angle... intercooled's had (i THINK) 145 degree and non-IC's had 155 degree. wrong spray angle will make for a poor running engine...

[@eddieashley1553]

The “cold air intake” was a complete waste of money.

[@bryanwilson2629]

nice but spend some more money and put a intercooler on it

[@braesimmers2719]

Is it a W250 or W350 just wondering

[@themadmailler]

350

[@sethparker1473]

You could have just adjusted the throttle cable lol instead of putting that Chain on it

[@Skeetmgeett]

Oh yes the elusive throttle cable? Good idea you clearly know your way around a first gen

[@mattmcf199]

where did you buy these injectors? i can't find them for a 89-93 cummins

[@themadmailler]

thehungrydiesel.com. they're not the easiest to find because the 370's are typically second gen injectors; THD custom installs them into first gen bodies. note that if you have a non-IC'd motor like mine, you also need to buy the 9 to 7 mm adapter washers for the injector noses.

[@Iskxvspeeddually]

😍

[@ianm1453]

Is there any way I can contact you for some help with installing a hx35

[@themadmailler]

+Richtis Grin there should be a "message" tab if you go to my channel, i believe.

+themadmailler there isn't. May I contact you by phone?

[@themadmailler]

that's weird. KZbin keeps changing all the messaging venues. shoot me an email, themadmaillerSPLATyahooDOTcom

[@transamfan81]

+themadmailler I also have a question about your turbo. I saw you have the wastegate solenoid mounted off the side towards the fender. is there anything you had to do to remount it like that? I tried to do an Hx40 on my 1st gen acouple years ago but the stupid solenoid was hitting my oil filter housing and trans cooler lines and I coundnt get it to fit. I didn't even think of remounting the solenoid like that but wish I had. This would really help since I need a new turbo and would like to upgrade from the h1c

[@themadmailler]

It is not a solenoid, it is just a diaphragm with a spring and actuator rod. As for the positioning, there are two options on the HX35, but i don't know why or what years they were used. My style is one of the ways they came, and the other is where the actuator is mounted on the compressor housing. with the other style, you aren't able to clock the compressor housing because you will mis-align the wastegate actuator, in which case you'd need to make your own bracket.

[@joshcampbell3860]

nice

[@ericjones7986]

NO NO NO!! do not use that damn kn filter. it'll dust the motor and you'll ruin the turbo when it sucks the charge oil out of that kn.

[@themadmailler]

It is an Amsoil filter. dry element, cleanable, re-useable. I heard bad things about KN filters so i didn't buy one.

[@rynophiliac]

do you have a part number for the filter or a link? thats exactly what i'm looking for

[@themadmailler]

no idea, sorry. I just looked it up on their website and ordered it, but now i see they changed their site and you can't shop by tube size/filter length etc.

[@iancole7829]

Couldn't just a just the throttle linkige

[@HAYSE557]

you can loosen the throttle linkage to adjust throttle takes 5 min max
