Tow Ported Cylinder Head Dyno Test

[@hallasnackbar1865]

I had always heard boost pressure was a measurement of resistance not volume, this test demonstrated that concept perfectly.

[@pddofficial]

Thank you

[@sHoRtBuSseR]

Yep. A lot of kids buy these trucks and can't make any power with them because they just crank the timing and boost up. These heads are terrible for flow.

[@michaelwilson5851]

Completely correct. I gained a lot of power and reliability by maximizing flow.

[@seanbrossard8178]

I can tell you when your taking your A&P(airplane mechanic) classes they beat the principal of a few dead guys in to your head. Bernoulli, Otto and Newton. and you better know Bernoulli's when you're talking about turbos and jets. And his principles work great till you hit supersonic.

[@dericksherwood6408]

Yes, simple law states how Flow & Pressure are inversely related!! The simple water hose analogy helps a lot of folks make the connection. But Soo many folks forget about Flux which takes the container through which the fluid flows. It is amazing how understanding a little bit of physics plays a role into so many different things.

[@Parents_of_Twins]

We bought our Dodge 2500 back in 2018 and I called these guys just to talk about trucks and they were so nice. Never made me felt like I was a bother or that I should be buying something just a lot of great info. Was a fan before then and that really illustrated that PDD is run by good people.

[@pddofficial]

Thank you we are all enthuses here!

[@dandable]

Todd mentions that they have people dedicated to just listen to your questions and to help steer you in the right direction. I can attest this is true. My uncle had them double the power on his 12 valve and the whole experience from initial phone call to the mechanics conducting the test drive after the work was completed at their shop. Just a great group of people at Power Driven Diesel. Highly recommend!!

[@goincoastaloutdoors6593]

Watching y’all talk about more flow with less boost just blew my mind. It makes sense, just also never crossed my mind to think that way about my head and turbo setup. Love the videos.

[@pddofficial]

Thank you

[@IanYav5.9]

they aren't kidding about that, I swapped to their 62mm HX super 9 and despite making less boost than my Aurora 3000 it makes a ton more power, just moves so much air it's insane!

[@460EFI]

Boost is an arbitrary number. More or less, just a point of reference. Obviously, compound turbos and pulling/racing applications are much different, but in a daily driven or working, single turbo application, if you're exceeding 40 PSI of boost, you need a bigger turbo. After 40, on most turbos, your drive pressure is going to start climbing exponentially, and the compressor is just blowing hot air. My semi is putting over 600 horsepower on the ground, with only 35 PSI from a single, 76mm turbo with a 31 PSI wastegate. Never exceeds 900° in the downpipe, even after several minutes at full power.

Thank you for the comment Getting our Engine dyno soon so that may be the content that we need

[@dieseldemon8562]

😂😂😂. Will’s reaction was priceless! I was along his line of thinking, but I guessed 940ish hp, for ~ +46 hp, and 2,050ish tq for ~ 112 lb ft gain. I am beyond impressed, but y’all never fail to deliver. If I remember the final numbers correctly, that was a +71 hp gain and ~ +200 lb ft gain- at elevation! I wish we could’ve seen the owner’s reaction and impression after the first drive! If possible, can you post some EGT numbers from before and after? It would be awesome to see the truck doing the simulated hill climb on the dyno for sustained power and EGT numbers!

[@pddofficial]

The truck is back home in Arizona, but the before peak EGT recall after a dyno run was 1800 ish and the after ported head peak EGT recall after a dyno run was 1600 ish or roughly 200*F EGT reduction, which is also an insane reliability gain! We would have guessed 50 to 100 degree EGT reduction, so 200 was mind blowing.

[@pddofficial]

Don't know maybe we need to try some clear valve covers and a go pro

[@pddofficial]

Will carefully checked over the old head looking for signs of soot/exhaust build-up on the intake valves and they were surprisingly clean meaning... minimal valve float at low lift during overlap or nearly adequate seat pressure. However, the factory locks/retainers were beat/pulled part way through and on the road to failure so likely had some valve float. Luckily this truck never sees 4k rpm or it would have probably dropped a valve with the original 60# valve spring and OEM lock/retainer setup.

Would have like to have seen an under hood shot of the dyno after the head swap. Seems to me that the bottom end should have been addressed, smoking like a banshee from blow by and the dip stick is zip tied so it doesn't shoot out. Maybe it smoked less? Just observing. Thanks for the video.

[@pddofficial]

Don't be fooled by the concentrated crankcase vapor coming from 1 single vent. If this truck had 3 or 4 vents like most "race trucks" do at this power level, it would not look so severe and the pressure would be low enough the dipstick would stay put. Furthermore, torque is directly proportional to average cylinder pressure. Making 2,100 ft lbs is BIG POWER and will create sufficient cylinder pressure to make significant "banshee" crankcase pressure, especially with an OEM style cast piston with OEM style ring pack. There are small compromises that happen to get longevity from cast pistons/steel ring lands at this power level including increased ring gap. Forged pistons are usually destroyed after 15k miles on a Cummins with ring lands beat out of them till they torch or no longer seal. However, 1000 HP is still fairly reliable with cast pistons and the "banshee blow by" can be ventilated better with the dual valve cover breathers to disperse the concentration of crankcase gases, but will not decrease blow by obviously. This customer prefers the clean looks of OEM valve covers and didn't want the dual valve cover breather option, so he deals with a zip tied dip stick and "banshee" smoke from the single tappet cover breather. If we filmed Will's Junker Drag truck making monster 1500 HP pulls with the same piston and ring setup, video recorded "blow by" would look less severe because he has 4 total crankcase vents. However, if we measured total blow by, the Junker would have more volume than this white truck due to the higher cylinder pressure and higher RPM window. One final thought, the OEM block usually fails around 2400 ft lbs to the tire, imagine much bore distortion is possible at 2,100 ft lbs like shown in this video, even a forged piston and high $$$ gapless ring pack would have trouble controlling combustion gasses on a power-distorted bore.

Late to the game on this, but would be interested to see what's behind the transmission, drive shaft, gears, if any that can hold all that power or if it's all stock.

[@pddofficial]

We build these transmissions in-house, this is one of our Weekend Warrior 1000HP rated transmissions: powerdrivendiesel.com/product/power-driven-streetstrip-1000hp/. Holding power for a quick blip on the dyno is fairly easy, it's holding the power while shifting and propelling a heavy truck down the street that separates the transmission part installers from the true performance transmission builders! In this model of truck, it starts life as an OEM 47re 4x4 transmission. It gets outfitted with a billet 300m input, intermediate, and output shafts. Line pressure is nearly double with the in-house built high pressure valve body. Clutch counts are increased from 4 frictions in direct/third to 6. Overdrive increased from 5 to 6 frictions. Several small billet parts, servos, strut, anchor, lever etc are added to handle the increased line pressure and reduce cross leaks or shift binding. Numerous lubrication mods are added for reliability in both overdrive, 3rd/Direct Pack, OD support, sprag lube, and 2nd gear band lube. The OEM 5 pinion steel front planet and overdrive planet are strong enough to handle this power level if they are in good shape, but the thrust load from monster torque quickly destroys the thrust washers (wear item) so we machine the planetaries, sunshell, and ring gears to accept torrington roller bearings. We also weld the ring gear as the OEM spot welds occasionally crack and fail at this power level. The OEM flexplate usually fails around the 500 whp mark so an SFI rated billet flexpate is installed along with a billet cover triple disk converter in lieu of the factory stamped steel single disk converter that commonly slips/fails around the 700 ft lbs mark or mid 350 HP on a 12v Cummins application. We top off our transmission builds with a deep pan for added cooling and extra fluid capacity; the cast pan also acts as a main case gusset to reduce flex from the monster torque/abuse. Finally we supply Power Torque ATF which has a higher coefficient of friction to give the wet clutches and bands just a little more bite than standard ATF+4. The whole package has to work together to reliably hold 2000+ ft lbs, and survive the brutal abuse of propelling a heavy truck and shifting without torque management(power reduction) that is commonly used in modern drivetrain design and engineering reliability.

This truck has a factory Dana 80, as far as we recall. Oem driveshaft with stock 1410 series Spicer ujoints so far have been reliable. We've put 1800 HP through a 4x4 with a Dana 70 rearend and as long as it wasn't shock loaded and bouncing tire burnouts, it held for a while although the axles started to shear at the diff side gears so the OEM 32 spline axles had to be upgraded with a 35 spline setup. On Will's 95' Junker Drag truck back when it had between 700 and 1000 HP, it started life as a 2wd Dana 70 and he twisted the output shaft slip yoke on the factory driveline, then a couple stock 32 spline Dana 70 axles where broken, and finally sheared off the 29 spline pinion shaft. The Junker was switched to a totally stock Dana 80 and has not had another problem.

Do you know what size injector this truck has? I don't think it was mentioned.

[@michaelhudson8453]

This is my truck. Has Dynamite Diesel Stage 4 injectors.

[@danielmarks4571]

@@michaelhudson8453 do you know the specs on the 362? I'm building a set of 362 476 compounds for my 12v and was curious how close the specs are. I caught Todd saying that the 476 had a 87 turbine

[@wesleytruax2469]

Do you know what size a stage 4 is 5x? Just curious

[@pddofficial]

it is 362 62x68 .70 and the 476sxe is a 76x87 1.25

[@pddofficial]

They are kind like a 5x18 but DDP is doing a really cool 10 hole injector that act like a small injector until you get after it

What radiator is in the truck.

[@pddofficial]

Stock radiator

[@nephron9924]

Do you guys sell engine blocks as well for daily use? I'm trying to find a 12v engine to swap into my Ford but maybe it would be easier to buy a whole engine setup by y'all?

[@pddofficial]

yes we build motors but for a swap you will definitely want a donor truck for all the small stuf and hardware.

[@Lukeleary]

Is this just a stock 215 pump? If not what’s all done to the pump? I have a 215 pump laying around at the house waiting to go on my 24v I’m curious if I should throw some gov springs, afc mods and delivery valves or if I should send it in to you guys to have it built up some more.

[@pddofficial]

it is a maxed and balanced pump with 025 dv and 4k gov springs

We have a milder ported (less CNC time) "towing head" coming out very soon that will be more affordable.

[@robertcotrelljr8573]

Does the build have a stock cam? Or upgraded?

[@pddofficial]

I believe we put in a 178/208 can in that when we built it

[@robertcotrelljr8573]

@@pddofficial cool was just curious if a 188/220 would net a little more hp? I installed that one with your replacement head I could afford the stage one so I cleaned the bowls up and mild porting. Just wasn’t sure what to expect with the bigger cam.

[@pddofficial]

We've seen setups like yours make as little as 240 HP and as much as 425 HP depending on who setup/tuned the fuel plate/AFC travel, timing, and turbo wastegate setting, overall health of the engine, fuel filter maintenance, etc.

[@craigr777]

An aftermarket exhaust manifold would probably net some gain and loss in boost/drive. Hey, I’m wondering what turbine wheel is in that S362, (65, 68 or 71mm). ?? I had a 62/68 and loved the happy medium. Also had a 63/68 + S478/87 compound setup. Sold the truck in hard times.

[@pddofficial]

This truck had an old stainless BD manifold. I don't think they make them anymore. Turbine on the 362 is the 68mm wheel in a .70 ar housing.

[@craigr777]

@@pddofficial Thanks for the reply! I thought I saw a non-stock manifold when they showed the old head coming off, but the owner said “stock manifold” in the video at the end. He must have meant stock intake manifold, eh?

[@pddofficial]

Yes, it has a stock intake manifold, and the exhaust manifold is definitely a BD manifold.

[@craigr777]

@@pddofficial Yeah, sorry that’s what I meant is it clearly was not the stock exh manifold in video but I got confused when he said “stock manifold”. I’m old school and forgot about the newer 12 valve intake manifold options.

How do you do a ported head without cutting it and do a runner intake

Most of the flow improvement is done in the bowl of the head not in the runners

Pretty modest to name your video as 900 hp, 65 is a lot

[@apuuvah]

Well dang, who needs Scania V8 anymore... LOL.

[@pddofficial]

Don't kid yourself, these hotrod Cummins trucks don't have nearly enough cooling capacity (radiator) to keep up with a dedicated Class 8 engine/truck platform. But it would be interesting to drop a 12v Cummins into a big tractor trailer and see how long it would last at say even 600 HP with 80k gross. We'd guess the fire deck would break clean off the block within 1000 HRs of abuse from thermal shock from the high power density.... only one way to find out!

[@CBDiesel86]

I’ve got a stock 95 Cummins with 359k if y’all need another tester!
