You guys are seriously underrated one of the best diesel channels no bs no smashing a product down peoples throats just information love you guys keep it up

[@woos31]

Just subscribed from Central Oregon, I can't tell you how nice it is to watch your videos and not have all these empty promises just to get numbers on the video! You share your info and knowledge which is greatly appreciated for a guy like me that just wants to learn and respects what you guys know and share about race engines as well as general information, so thank you gents and keep these videos comin!

[@anthonybartolini2491]

Nice! Central Oregon here as well!

[@oldiron3735]

Thats an incredible display of near bulletproof parts! I hope everything comes together well on this build!

[@Mike-xt2ot]

As a gas engine builder/racer I am just in awe!! I respect the hell out of you diesel guys. The size of those components are absolutely huge. I saw your engine explode on that 1/8 mile pass when your engine stop malfunctioned. To see such massive weight reciprocating assembly revved to 8 grand when it came apart is a testament to yalls build quality. Gas engines with lightweight components have many failures below that rpm The diesel world has exceeded all other engine platforms in making something that theoretically would seem impossible, possible. Hats off to yall.

[@Danv941]

Love the videos. No silly clickbait or attention seeker garbage, straight to the point. keep it up. Im interested in the oil pump, will you be selling these on your website?

[@johnhawkins8049]

agreed. i prefer more simple videos like this with no movement. alot of info right into the camera on a tripod is great with no distractions. i also agree with the machined 8.3 oil pump. seems like a really nice upgrade. hopefully it stays together under load.

[@corystansbury]

I agree. Fantastic video.

[@matthew8329]

Best diesel channel. Science, turbos and 12 valves- perfection

[@benmartin3381]

Genuinely one of the best engine and diesel related channels ever. Keep up the awesome work!

[@gregpeterson8490]

That turbo is MASSIVE! The one in my Freightliner looks like a small ashtray next to that one. Great videos!!!

[@letterpool]

Not a diesel guy but wow, some nice beefy parts out on that table! Had to watch the whole thing. Very cool!

[@garethmccash5986]

love the channel guys and for being able to explain diesel tech in laymans terms. keep it up

[@garethmccash5986]

when will the street beast be back kicking arse? Im also amazed at the fab work thats gone into the truck...

[@demon39063]

Thank you for putting this video together -- this is so interesting. Can't wait to follow the build!

[@RubberChicken10000]

Very well put together and informative video. I enjoyed your appearance on Finnegan's Garage and was pleased to see you had your own channel.

[@jdw329]

Yea my cummins will never need these parts but sure didnt stop me from watchin this! Awesome video thanks guys

[@fishingTG]

You guys should do a video on how to install injector nozzles for a 12 valve. There's no videos of anyone doing it. I have a pop tester but not sure on the correct way to do it

[@jayknight139]

Love this video . Keep em coming please because not enough tech talk out there one high performance diesel.

[@sticrzy123]

I run DLC bolt Carriers on my AR15s , that’s some awesome stuff !

[@kikkilinu]

Guy on the right looks like an American Turbo Yoda

[@kikkilinu]

Haha let me know what he says!

[@Mike-xt2ot]

With the higher quality more durable components does that add to the weight of the assembly and total engine weight?? Or is there weight savings elsewhere on the engine to offset it? Thanks

[@wesleytruax2469]

love how you guys explain everything can't wait to see the motor being put together

[@jacobmoses3712]

Have you come up with a solution to prevent torque converter bolts either coming loose or breaking?

[@BuckingHorse-Bull]

i dont have a diesel but i appreciate the presentation. i learned a lot. i subscribed because of this vid

[@EveretteMartin]

Cant wait to see you guys at the UCC!! so pumped!

[@dredgenyor1674]

Im attending UTI soon, to become a diesel tech, i really hope to be as knowledgeable as you two are!

[@douglaslambert6109]

Try your best use your head stay in school.

[@legocommanderstar]

is it easier to build a 12 valve or a 24 valve cummins? which one is stronger from the factory?

[@jaymiller6062]

now that's a turbo, holy cow.

[@rowdykrowd435]

Awesome to see the internals of these big builds, would like to see some of the electronics sensor, gages, probes, turbo timers things like that.... how you keep tabs on vitals !?

[@paulmryglod4802]

What is the rpm upper limit on that new rotating assembly? Does the additional strength offset the additional weight for spinning it faster? I'm new to diesel.

[@Thesongstaysthesame]

You guys have a fantastic thing going! Can’t wait to see you guys at UCC18!

[@chuckdaly3164]

i first meet you gentalmen on finnegan's garage and enjoyed what you do and how you share with us how it all works!! and now i've found you again! sad to watch how things went on your last dyno run! now again I am enjoying watching your upgrades to address how much power your creating with this engine! thanks for sharing! just wondering how finnegan's ramp truck is going? I'm still stuck with gas engine's a little 302 ford and couple 350 chevys, although i'm very intrigued with the 12 valve and will some day implement one in a truck!

[@chuckdaly3164]

love that fact re:12 valve & swaps, can't wait to see the ramp truck rolling!! thanks again for keeping things as simple as they can be for all of us!!! Gentlemen you are the best!

[@scarface-39]

I've always wanted to know what beefy Parts you guys put in these monster horsepower engines thanks for the info good stuff!!!

[@desmondmoonbear4143]

What transmission do you run

[@Brian1996akatree]

Would you ever consider producing the 8.3 oil pump that you customize to fit in a 6.7 or 5.9

[@garretolson5383]

What kinda trans do you use to hold up to that kinda torque

[@joeygarivey3122]

What pistons would y'all recommend if you were going to run that power on a daily driver

[@2cYourVideo]

Daayyyuuuum! Informative as always looking foward to the build post performance evaluations.

[@groomlake51]

Is the 12 valve the ideal head because of strength ? Or does it also have to do with low lift flow characteristics and curtain area of 1 big valve vrs 2 smaller valves with the same area?

[@groomlake51]

PowerDrivenDiesel it’s cool to see a lot of the technology of our sport start to trickle over to you compression ignition dudes. Are shop is next door to Fleece. They are smart dudes. It’s crazy how much power you diesel guys make. I run a lot of alky hemi motors on the dyno. It was built by Dale Armstrong for Kenny and the Budweiser King team. It’s a navel ship dyno he converted. Rated to 5,500 lbs/ft. They used to run Fuel motors on it in the late 80s but now we just run alcohol engines on it because it can’t handle 8,000-9,000 lbs/ft a nitro motor makes now days. I know just how hard it is to make 2,500-3,500 ponies. To see cummins engines make that now is unreal!!! I fly in to the races but during the week I work as a engineer at BMEltd. We make pretty mean 14& 16/71 Roots blowers. I always get calls about trying to put are Top Fuel Rods in a diesel... but I’m Still waiting for some one that wants a blower🤣

[@groomlake51]

PowerDrivenDiesel do you understand what I’m saying about “ curtain area”? And how 1 big valve flows a ton better at low lift off the valve seat than 2 smaller valves. Are engines make 11,000 hp with 2 valves and only 500 cubic inches. I’m pretty sure a lot of pulling guys are using are inconel valves now on the exhaust and intake. Why not run a Ti valve on the intake? It can’t be EGT because nitro runs a lot hotter. But are intake is a lot bigger than the exhaust so the weight helps. How much spring pressure at installed height do you have to run making 150psi🤣 we only make 70 psi but the back of the valve has almost 3 square inches of area. We used to run 300lbs on the seat. Then dell one say did the math and with 70 pounds of boost on the back of the intake valve the dynamic spring pressure was only like 120-130lbs and that’s why we where floating the valve. I have a 5.9 and they have little girly springs. With a 12 valve head with a big intake and 100 psi of boost I bet there’s a ton to seat pressure on the intake to get it to close. We now run 700-750 on the seat. Around 1300 over the nose💪🏼🚀

[@trapshooter91]

A couple questions... What cam bearings did you use? Since you obviously opened up the cam bore diameter. And since the stock only uses the front and back bearings did you opt for a roller bearing? 200 lbs of seat pressure is alot.

[@trapshooter91]

Thats cool! Fomoco parts in a cummins might be against the law tho. Lol

[@derJackistweg]

Very precise on the point and very nice take over between you two. I am wondering how German legal department (street) will react when I would go there for the usual 2 year control. 😱 I am pretty sure they have never seen a 100 mi turbo on a car. Especially not 3 of them!

[@victorgirouard1543]

How is dry sump oil system to expensive? When everything else in the motor is top of the line or upgraded

[@danielssonsgarage]

Yeah wierd. You get more horsepower with dry sump too thanks to the crank works in vacuum witg dry sump instead of pushing oil around

[@jamiecanter4166]

What crankshaft are you guys using

[@williamloewenhagen7784]

You guys said you run a 6.7 block. Do you sleeve the engine and then make it back into a 5.9? Another question is do you have alot of blow by. From what I have learned about tractor pulling is that that hone out the engine to have lots of blow but to compensate for all the boost.

[@williamloewenhagen7784]

Thanks you guys are awesome

[@sidecarbod1441]

Just come across your vids, they are very good! I'm surprised that you think that the rod bolts are placed under a tensile load as the piston reaches TDC because there must be a hell of a lot of gas pressure on the piston pushing the piston and rod back down the bore. I could understand that the rod bolts are under load when the engine is on over run but even then the gas pressure must be pretty high.

[@sidecarbod1441]

Fair enough you are right, on the exhaust stroke there will be a lot less pressure above the pistons although a suppose there will be still some pressure especially as you have a turbos creating some back pressure.

[@jakehaberhauer2585]

I know this video is old, but I have a first gen getrag 5 speed. It has a 3200 rpm gov spring, fuel pin and some ve44 pump work. But I'm looking for a little more. I know the ve44 isn't the best for big power, but I'm just looking for a reliable high 300/low 400 horsepower. Do you have any suggestions for "doubling" the horsepower for these trucks?

[@bbdl7042]

Jake Haberhauer gov spring 4K, 60mm turbo, little better injectors like 100hp-125hp, exhaust, intake, intake elbow, than do the actual fuel system

[@jakehaberhauer2585]

Bbd L I have a 3200 gov spring, fuel pin and the hungry diesels low pressure high volume lift pump. I've been looking at some 5x12 injectors, a second gen intake elbow and now a hx35. Hopefully after all the mods it'll wake the truck up more.

[@bbdl7042]

Looks like a good list just do some research on the turbo I’m not a fan of the hx35

[@traviswoosley7388]

How much should it cost me to have the head rebuild and the number 4 piston replaced????

[@jacobmoses3712]

Are roller tappets available for Cummins engines?

[@michaelcuff5780]

Thanks! Learned alot in this video!

[@notahuman369]

I'll save everyone some time. Diesel. Diesel goes into a 2500HP Cummins engine.

[@melissahill8698]

3000+HP Rods! That's insane. I'm so fascinated with all of these builds.

Man I can’t wait for the next video keep up the good work

[@24vcummins99]

PowerDrivenDiesel sweet man can’t wait 🤤

[@ridingwiththereids]

So how long would my engine last if I built it with 80~% of these parts and didn't push it much past stock?? Let's say 250-300rwhp??

[@dmc2554]

pistons will fail at the ring-lands just like buddy said

[@snliner1308]

A stock Cummins already last a life time. With 80% of these parts it will probably last to the next ice age.

[@dmc2554]

@@snliner1308 Nice boat motor, eh?

[@Sir.VicsMasher]

Have you thought about testing this engine on a Spintron? I know Steve Morris Racing Engine's has been using one with great results.

Awesome video cool that you show everybody what’s going into it people like to keep everything secret can’t wait to hear run you guys should go over the fuel system later on

[@Ryan_Driedger]

Good job guys can't wait to see the next video

[@177SCmaro]

300 CFM from a 2 valve diesel head is pretty impressive. That's about on par with an LS or Coyote head.

[@ciscoarmijo1353]

Need one of these videos for a 6.7 Cummins

[@biglouy]

Any particular reason 2 of the pistons appear to have a domed top and smaller bowl?

[@biglouy]

[@thegoodgamerguy3387]

hey pdd, idk if you play around with duramaxes but mine is getting a chugging idle with white smoke any clue what it is?

[@alonzo5800]

that could be so many things and is pretty much impossible to diagnose over the internet like this. I'd suggest spending some time reading up on any/all duramax forums and going from there.

[@masoncameron6443]

Its a piece of shit

[@Richie_RHD]

Yet another enjoyable video. Can’t wait!

[@bandabanderos]

Is the 6.7 block sleeved and or deckplated?? I always thought you ran a true stock 5.9 block. That air though......😮😮😀

[@bandabanderos]

PowerDrivenDiesel so not a wet block?

[@jaeh8556]

It would be so cool if you put this in a smart car or Geo metro.btw why not a compound turbo?

[@yannai0h]

Why not convert it to direct overhead cam?

[@miguelmiquel5497]

is there a 24 valve head?

[@dredgenyor1674]

Would you recommend i run your oil in my duramax?

[@MrSehka77]

How much money goes into a 2500hp Cummins engine ? That tittle would be appropriate as well .. Great video

[@Dogghousse]

$10,000 bucks easy in engine parts alone. Then paying someone to assemble it, then the fuel system, then exhaust and fabrication work, then driveline parts, then electronics to control it all. Now your up to $20,000 bucks on the low end of cost..

[@groomlake51]

Your cummins wrist pin is about twice the size of a nitro wrist pin. We use a taper wall wrist pin in Nitro motors like most all other drag racing engines. There’s twice the surface area in the pistons pin boss towers compared to the little end of the connecting rod. Because there’s twice as much more surface area a taper wall pin is ideal. I worked as a engineer and planer @ BMEltd is I had a dollar for every diesel guy calling to ask about using top fuel rods on diesel motors I would be rich. It’s crazy how manny misconceptions there are because magazines. I will say that Fleece performance is a bunch of great guys. There shop is next to my teams shop in Brownsburg. The fleece guys are all very smart and class acts

[@blacksmoke5009]

Great stuff guys thanks for sharing 👍

[@dieselboy6988]

Think you guys could talk about the fuel setup?

So why flat tappet and not a roller cam?

[@daviddroescher]

Why no roller cams for cummins?

[@daviddroescher]

PowerDrivenDiesel thank you for the 3q's quick, quality, question-answering. It was the same for the gas version (sb350) power/$ raito not worthwhile till competition pushed forward then were ban to keep cost down and car counts up on the dirt track.

[@hunterhewig2459]

how much torque are you making?

[@speciosa146]

Jesus man, at 4000 engine hp that'd be like 6-8000 lb-tq right? That crazy for a little 5.9. Hell a 15 liter cat 3406 "only" puts out a quarter of that. Keep up the great work
