DIY TURBO 440-MOTORHOME GETS BOOST!
HTML-код
- Опубликовано: 10 май 2020
- FULL BOOSTED RESULTS. TURBO 440 MOPAR. DIY TURBO KIT. Boost is what every low-compression, Motorhome 440 needs. We ran this test on pump to illustrate how well the 440 responded to boost from our single turbo. Using stock (cast) exhaust manifolds, I fabricated a kit that included a Y-pipe with dual Turbo Smart wate gates and a single VS Racing 7875 Gen 2 turbo. Big Torque!

I know the budget would be just unreal but man a big block Big Bang showdown between the big 3.... 440 vs 454 vs 460! 🤤
I love my Edelbrock headed 440, but factory development stopped in '76-'78. Ford and Chevy big-block development went on for many years with EFI and much better port designs. Unless you want to talk Pro-stock B1, or Hemi---> nothing budget about those.
Yes! Send some Patreonage Richard's way so we can see this.
It would all be up to parts availability and we know ford and Chevrolet have everything aftermarket down to each bolt Chrysler would keep up due to no aftermarket parts at least not as many
@@utahcountypicazospage5412 What?
@@utahcountypicazospage5412 All he would change is the heads, cam and intake. Whole point of the big bang is to see what the stock rotating assembly can support before it turns into a Jackson Pollock painting in the dyno cell
Gotta say, as someone who has built 440's for 50+ years, you UNDERSTATED the potential of this factory motor by a country mile. Superior rod ratio's, skirted block, shafted rocker train, widest lifters in the industry, improved casting bulk heads and main webs; this engine with the factory forged crank (standard thru 1972, but appears cast based on damper) will handle 800hp NO PROBLEM. BUT, you did the right thing holding in the 500hp range with cast crank.
the cast crank will go way over 500 hp-I limited power because it wasn't mine
Dang, its amazing to see what 5 to 7 lbs of boost did to a tired old 440. That thing LOVES boost.
I'd rebuild this tired engine and give it a complete refresh, then I'd add on the turbo kit you made and install it in my '71 Demon. I'd run it at 7 to 8 lbs of boost. With around 600hp and over 650 lbs-ft of grunt, it would be a street demon for sure. At that power level, the 440 would be so under-stressed it would last forever. Kick ass!
Uncle Tony has a episode with a friend and a roots style blown 440 that is all bone stock handling it for years, you sir are correct with your statement
I built a 440 using all forged internals, 906 heads, full race prep, oil galleys,balance, align bore,deck surface, ect ect using a Baha torque master cam 8.25 comp and 22p boost in a 15,000 kg International truck on straight propane using USA OHG equipment 5 sp gearbox 2 sp diff as my every day money maker, here in Australia TOTALLY INSANE, estimated 650 hp at 5000 NO TROUBLE pulling full boost up a 5 mile hill fully laoded, ONE TUFF BLOCK these things.. 120,ooo miles still going strong., if i could add photos would be happy to do so. By the way, TOTALLY LOVE THIS SITE... Please keep up the great work...
Great job Richard, good to see a pump gas motor and "sensible" boost lol. Would make a fun street car
Thanks 👍
I agree, this setup is attainable for the average guy and as long as the base engine is in reasonable health, not too many nuts in the pan, it should be reasonably reliable. And very street friendly.
@@watsisbuttndo829 Agreed. As long as it's just one nut, attainable. Just watch out for a second nut.
@@dj4monie agreed, i have a 65 gto that has power steering and air conditioning that i definitely want to keep so i have a cramped engine bay already but a rear mount low boost blow through carb setup is interesting. Ive asked in the comments before if he could mock up a rear mount setup with regards to pipe length and test for spool times compared to front mount but if its on a near standard big block lag becomes pretty irrelevant.
With the size of the harmonic balancer so big, it looks like a cast crank. Factory Chrysler pistons usually are pretty heavy/beefy and would seem to take and dispurse a load of heat and handle the pressure of a long incline/grade.
It stood-up to Richard's boost, albeit moderate as it was, 650 ft lbs of torque is rather significant.
Not sure if sufficient ring gap is on those pistons, but I would be interested in a 15 or 20 minute run at the 600-650 torque level.
Now THAT would be an excellent test of the rotating assembly on a Raised Block Mopar!
I pray Richard keeps Big Block Mopar engines in mind for future tests and upgrades.
If you guys didn’t notice those stock log headers is what was really holding this engine back think about it with any kind of headers bet it would make at least 40 more horsepower even if it was small hot rod headers 😍
I have a 440, sitting the backyard, if you want it for More Tests!! I'd like to see the limits of factory part on Boost! Lmk!
Id love to buy one for my 69 cuda my email Moparmatt1@gmail.com
I need one for a Plymouth
Thanks for finally doing a 440. Heads and low CR are the achilles heel of motorhome 440's. They still make great torque and that's what makes for big fun in a street car!
Stock heads are fine. 906/915s flow good when modded with bigger valves and a port job however the cost of labor isn't worth it anymore with cheap aluminum heads with every mod already in them - that and the weight saving lol.
In fact Steve Dulcich wrote a series of articles on the 1970s iron heads where he forensically tested and compared them to the 906/915 heads of the 1960s and found the so called 'smog' heads of the 1970s were actually better for flow. Admittedly he didn't test the motorhome heads but I think the only difference was the tapered plug heads, so correctly or incorrectly I reason?? they are probably pretty good for flow like the rest of the 70s heads.
Here you go. Dispelling the myth of poor flow BB Mopar heads of the 1970s.
Well worth a read for the big block Mopar man:

I think that the engine has the pistons set in the hole slightly which is bad for combustion efficiency. Id low buck it with some heavy cast pistons and good rings to achieve a zero height to the deck, maybe some rod bolts, definitely studs top to bottom, then run alcohol through it.
@@ThePaulv12 i have a set of the motorhome heads on my 400. they have been bowl worked. they seem to run just as fine as the other smog heads. i like the spark plug cooling jackets.
@@hoost3056 Not slightly down - mid-late 70s 440s have pistons around .150" down, you're not going to find a cheap tall piston to make up for that. A 3.90 stroke crank would be near-perfect for a zero-deck engine, but those aren't available anymore, and if they were they'd be for BB Chevy rods - which spoils the low-buck aspect. And balance might be off at that point anyway.
The low key goal of this channel is for Richard to boost every engine he can get his hands on. HAHA I fully support this goal.
They did offer a turbo kit back in the 70s for the 440 motorhomes.
I actually have one of the old RV Turbo kits on the '68 440 in my W350 four door, high compression and boost makes for a very fun ride.
@@spotsornot Man that would be awesome in my '81 W250! That torque & HP seems essential in a motorhome.
Thatd be a cool way to turbo my 413 magnum
This video just made my day! I'm doing a twin turbo budget build 440 in my rat rod and I wasn't expecting over 500 hp. I'm really fired up now to get it done!
That was great and gives us Mopar guys another power source. You notice the engine came with chrome valve covers to block those gamma rays and space lazers to increase hp by at least 5 hp!
its really neat to see the single Gen2 doing so well on a 440 inch engine
That's cause the stock heads have the ports of a small block..
This gets my rocks off. Likely build for my spare motor home 440
I was waiting for this. My dad has do many 440’s in the Garage and I been trying to get him to do something with them
I love it when Richard builds a damn good Truck engine. The thing would be a boat towing beast.
I love this show! I each it every morning with coffee. Want to know the best way to start the day? MORE HORSEPOWER!!
It's all fun and games till you put creamer in the cereal and milk in the coffee... But its okay cause boost makes the world a better place
LOL! Yep - MO POW-wah, Baby! 😁
Mopar 440 with turbo is a great idea.
I love the fact you have timing info on this one. Please keep doing that. Thanks.
Wow, you wouldn't get that info on a ls engine. Must be information we already know???
Here for the 440, subscribed for the craziness!
Thanks a ton for posting this! We just wrapped up a 451 stroker build based on a 400 with "Motorhome" heads and in the next phase with that motor will be adding boost, definitely cool to see some real world numbers on what to expect!
Awesome finally mopar stuff..BIG BANG A 440! wooHOO suscribed
Richard, you always add something cool to the early mornings. Coffee+ Boost= JOY
Glad you enjoy it!
Seeing all this turbo plumbing reminds me why this is one of the best channels on RUclips.
8psi turns that thing into a respectable engine. :-)
yea, because 600 ft lbs isnt respectable at all...
For a smog era 7.5-1 compression engine it did great.
10:1 on one of those with a trick flow top end kit give me 630hp n/a
@@hmbrew2754 how much did that run you?
Richard, as a C body guy. I want to see a big bang with the Chrysler 400 smog motor. Dime a dozen and no respect in stock trim. Also look down, the caddy guy has got a point. Those a real cool too.
Got the 69 newyorker for demonstration!! Who’s up for that challenge
Isn't that nice of Chrysler, had so much confidence in their product they were giving away spare parts with every Engine LOL.
Been waiting for this and did not disappoint thank u!
Excellent video! Truly low budget boost. I like seeing the potential of relatively stock architecture engine, without a lot of bolt-ons. Please do more of this type of testing.
Nice to see something more than dyno graphs recently.
Thank you.
Glad you liked it! I'm at Westech so I can do more when I'm here testing
Thank you for the Mopar B/RB love. Hopefully we can get some full Mopar builds in the future, always limited testing for the "other guys". Great series!
Awesome videos !! Discovered your channel a week ago , the only thing i can say : THANK YOU :)
Glad you like them!
Thanks for doing this. Really neat. Its nice to see different engines on the dyno. Great job as always.
Love the other guys builds, great job as always!
Working hard on the weekend just for us, Thanks Richard!
Awesome job thanks for all you do and taking any guess work out of any project enjoy your work sir.
I approve of this line of modification!.
good video! i like the practicality of it. I enjoy pump gas tests much more than race fuel tests. thanks richard.
😁 Nice amount of information, Thank you ,I have a 76 Powerwagon 440 and now I know what to expect with these setup's
This is the closest thing I have found to what would happen if I installed a turbo on my '95 Chevy 454 RV, provided a blow through would even a stock TBI. Keep up the good work 👍
Well the turbo setup has my mind thinking. That is absolutely streetable and the bottom end power is great from a dig. Thanks!
I love these motors and bang for the buck great way to toss something like you mentioned in a car or 2wd pickup GREAT VIDEO
Awesome video. Thank you Richard been waiting for this one. And thank you for working on Sunday (mother’s Day) to have the video up in time.lol you must of put up with a lot of grief yesterday lol
LOL Richard "We obviously didn't stop there" Holdener.
You are the man! Now Steve D can put it in the Mopar Muscle Truck with a homemade turbo system like yours! Keep doing what you are doing!
I wish!
I love this video! Showing what you can do with the old and I’m sad to say it but obsolete engines like these big block low compression engines like an RV 440 or a FE engine on pump gas love it because it’s something you can do and drive all week and get on it when you want and not have to worry about race fuel or e85 I hope to see more like this video I was so pumped for the last 2 days for this video!
Shows how well low boost 5-6psi pump gas works on a stock motor. It is not always about maximum power.
Most interesting take away from this test was when looking at the boost formula. The 440 made the 346 hp with long tubes. Then when turbocharged it had the stock manifolds on. And yet the formula held pretty close.
Always come back to barracks looking forward to see what Richard uploaded the night before
ITS A-L-I-V-E....,nice build up. Dr. Frankenstein would be proud. Thanks for your hard work and practical data.
Glad you enjoyed it
Awesome experiment, great videos!!
Great video I always enjoy watching your videos but I like it when you show more of the build and set up in tuning instead of just showing the grass and stuff alone. Keep up the great work and videos coming
This engine would be a blast on the street, I’m thinking 4 door or D100. 😁
Good to see you using the gen2 7875, my 5.7 ls1 is loving it, just has a custom t51r mod done.
Nice one, I'm sold on the turbo idea. Peace from Australia
I love the other guys stuff being a mopar guy how about a b motor 383 there are more of those than 440's do some modern heads cam. And intakes carb and fuel injection
I think I picked up the perfect core for this!
Stock 76 440.
I’ll toss a cam at it maybe an intake.
Would probably try my hand at building a carb for this but overall seems easy enough and great torque for a polara wagon I gave
That was Awesome brother 💯👍 , love it
Thanks for sharing the information on the ignition timing, I hope you can do that on your other builds.
I have seen a series on RUclips where some guys swapped a turboed LS into a Winnebago. The downside was that the engine had to be buzzed up before it would perform, then it went like hell. A motorhome with this style of engine would keep its stock manners, just be faster
Your nuts!, but a good kind of nuts!. Well done Richard.
Love seeing the mopars.
Not bad for a worn out 440!!! Thanks Richard!!
Mopars in most cases have the strongest factory blocks and rotating assembly of the big 3. There down fall are the heads. Its pricey but a set cnc heads and intake would wake this thing up big time.
loving the behind the scenes action my man!
This engine would go great in a charger , Cordoba , an A body would be a killer...........love you Richard you prove hair is for suckers!
Love it Richard!!!
600-700 ft lbs is a whole lot of fun no matter what you drive.
Big bang 318!!!
You probably felt like a plumber after all that. Thanks for the great 👍 vid. Thing is a torque beast.
Put an intercooler on that beast and I'd run a grade with it!
I had a boat with a 460 ford engine I replaced it with a small block ford 302 I bored and stroked to 352 with a 70mm turbo had a dart block out of a mustang used to drag race. The engine made more power and torque was lighter then the BBF engine. I only ran 5 LBS of boost because I wanted to run pump gas I did test it up to 18 psi on a dyno got up to 740 hp and 850 lbs of TQ. That was with Trick racing fuel.
Yeah, that setup would fit REAL good under my hood, LOL. Of course, I could go Roadkill and leave the hood OFF, but it rains a lot around here.
Thankyou for doing anything that isn't a ford or chevy! The fact it's a 440 is icing on the cake. I would like to know the original application for the log exhaust manifolds. The high performance ones wont work with a turbo.
Love the Holdener patented boost formula!
Wow! Can U say. TURBO L A G !!! All that tubing. In Duluth in 70's we TWIN turboed a 440 built boost up to 22# to how much it could take!
Autopsy the rods were in a S shape ! (440 were essy to come by then)
Rite after that, Edmond Fitzgerald sank.
Love the content!!!
Keep in mind guy's. On the highway that thing is going to be making more power then it can in the dyno room. The weather helps sometimes too. There is a drivetrain loss but you can't fake a big turbo on the high in the higher gears at the upper rpms!!
that makes me really curious about running boost on my olds 350. you certainly made the whole thing look very simple and easy haha.
Love to see it with a 400 magnum! 1974 dodge charger style
Every day it's another wildly entertaining video. To be honest, I'm a bit disappointed you didn't window Freiburger's block though. Keep up the great work.
I think it would be very challenging to get all the turbo stuff in a engine bay. I wonder if cooling this engine will be a problem? Keeping a 440 magnum cool in stock form is challenging enough.
This (other guys) is awesome!
Richard, it would be great to see a boost video explaining turbo applications. You Know single, twin, compound, and sequential turbos and thier boost applications. There is no one best boost setup it'd be good to explore the individual strengths of each application. After all who doesn't like a video on Boost!
Noted
Need to get a Barra over there and tinker with that, Richard. I think if anybody could put it through its paces, it's you.
Found a rod nut in the pan of a 440 from a 1977 Chrysler car. (changed pan for a pickup swap) Right off the bat I'm saying bad words! But all nuts were in place. I guess they just liked to throw in an extra one back then. 😆
SPARE
Speaking of rv motors, let's see what happens when you turbo a Ford v10! A friend and I have been talking about it because we have a rv with one.
Tony Bain I’ve heard the bottom ends on those are pretty weak. No personal experience though.
They're built like a 5.4, basically a 5.4 with 2 more cylinders.
Tony Bain th se engines were designed for trucks. Low rpm high torque applications are where this engine shines. A small turbo (keeping boost around 8-10 pounds)with a small cam designed to increase torque might be a good application. I think as long as you keep engine speed below 5000 rpm it would probably work just fine
Until ya blew out all the spark plugs, ask me how i know!!
Finally the VS-Turbo
Pretty interesting
That thing would be fantastic in Freiburgers Super Samurai!
Nice very nice richard
Not bad for a junkyard engine missing one rod cap nut ! Amazing!
That motorhome needs that Pontiac 455. 😉🤘
Great to see a mopar. Richard you should do a 318 magnum big bang from the junkyard
Great video. Definitely would like to see what can be made out of an old Ford 460. I have one laying under the hood of a old work/service truck.
Thanks Richard! Very grateful for this test on a mild mopar rb engine as I've been looking hard at a turbo for my 383 superbee. These old beasts are tough and they can make serious power on relatively low boost and pump gas. I'd love to see this with some block hugger headers and plumbing that would fit in a b body mopar. Sounds like Dulcich and Freiburger may do it soon
Mr Holden i think you are a guru in analyzing, and building the old 440 low compression engine,,, you make it seem so simple,,, this is "ole man" black Bart
That was pretty smart on that boost level . I was thinking yesterday wonder where he will stop and at less than half of one atmosphere.. if you wanted to see what a 440 or a stroker 400 is capable may be use some indy components. I guess there still around . I left the dodge camp 40 years ago . Now it just interested watch
Richard's new handle is "scooter"!
Great Test. I thought of doing this years ago, but I couldn't figure out how to fit all that plumbing under the hood.
Diesel or gas one never lugs their engine which by the way destroys more engines than over revving, that is why you have transmissions so one can select the right gear to keep the engine freewheeling, which is why we are seeing 6-, 8- and ten-speed transmissions. With 3.92 gears in my 07 ram 1500 I tow in 3rd gear which is 1 to 1 and get 11mpg opposed to 4th gear, tow-haul mode, which nets 9mpg and overworks the engine. I run tow-haul mode in the mountains with no trailer, again to save the engine and get better gas milage. No better way to hammer the bearings out of an engine than to lug it.
Lol... Richard, I worked at a Dodge dealership back in the late '70s as the new car prep man. We had cars coming in from the factory with everything imaginable wrong with them.
They apparently had **zero** quality control. It was very common for them to arrive with no transmission/rear end dope... doors would be totally out of adjustment, bolts missing, torsion bars would be cranked up on one side and down on the other, power window/seat switches in upside-down, and on and on... They kept me working hard as I could go, all day long, every day.
We even had one come in with a bad miss, and after I checked to see why, (believe me, I realize how hard this is to believe...) I found it was actually missing a piston and rod.
So, a nut in the oilpan..? That's **nothing** for a MoPar.
Michael Angelo
Holy shit those are some funny stories.
Big thumbs up
@@fastinradfordable Yeah, it's easy to see why they almost went out of business after all that.
They also sold the little "Dodge Colt", which was really a Mitsubishi, imported from Japan. Interesting to note that those little cars were all perfect. All I had to do on them, was to remove the protective plastic covers, and tighten up the battery cables because they were removed during shipment.
I worked at a Chevy dealership for a few years and we had a Tahoe delivered and the rear hatch said GMC Yukon
