Turbo Dyno Test HX35(60mm) vs BorgWarner K27 | Power Driven Diesel

In this episode, Will and Todd test the Aggressor HX60/60 on PapaSaurus, the 410k mile, high mileage 12v Cummins. Will the HX35 based 60mm turbo make more power than the 58mm Borg Warner K27? Watch and see! As an added bonus, they pull the silencer ring and mess around with the air intake system to perform a "hot air intake" test. Gale Banks would be proud! #doitforGale

This was the content I've always wanted to see, because there is so much misinformation and seat of the pants guessing on the performance of certain turbos.

[@dieselboys346]

This is why y’all’s stuff blows up all the time. That’s so stupid running a cold engine especially on a diesel. If you had any idea about how engines work and what heat expansion is you would let it warm up. Then admitting it wasn’t a fair test because it wasn’t warmed up and saying “it apparently likes warm runs” like no sh!t I wonder why. I feel bad for your customers.

[@pddofficial]

Why so spicy? To clarify, a "Cold Run" was that it had idled for a minimum of 10 minutes and had done a low 100hp pull first. By cold run we simply mean that it hadn't been heat-soaked first with a 300+ horsepower run just prior.

[@clancytaylor7714]

Well at least Todd has his seat belt on so he don't fly out of the truck on the dyno🤣

[@valve-do3jc]

Keep it up love your vids. Dose this mean you’re going to rethink your compound set up? Before I purchase.

[@pddofficial]

Luckily the HX35 and K27 share the same footprint so with a simple bracket change, they can be interchanged in the ultimate compound turbo kit, if we find gains with the larger turbine HX Aggressor turbos in that kit. The dyno will hopefully tell the full story soon!

[@coalstang]

be cool to see a he351cw tested against these. how does that tight exhaust side hit such big numbers?? or maybe it looks small but flows well somehow? wastegate port size helps it?

Tell us what you REALLY think about Gale Banks! (seriously, this is going to be golden) :'D

[@chloehennessey6813]

Gale Banks is The Godfather of diesel performance. He’s held world record diesel times and numbers. When I start seeing those same accolades about PDD? I’ll worry about what they think of Gale Banks.

[@compted10]

@@chloehennessey6813 he has done good things but I can never forgive his selling out of diesel performance to the epa. All companies that kneeled to them should be ashamed and will get none of my business. I do not go around rolling coal but I think you are well within your rights to do so. I also believe diesel emissions equipment is the ruination of what would be a long lasting and reliable vehicle.

[@73cjproject]

@@Rx7man I haven't ever messed with the pump timing on my first gen. I had it rebuilt and tuned for the bigger injectors I put in it. There is more power in the pump, but it runs so good and honestly the transmission won't hold anymore power. That truck has since become the toy and going to throw an antique plate on it next year when it is eligible. Meantime I have an 05 and 08 that I use. So I still have my mechanical truck but I am a wire fire convert, dynamic timing opens up a whole world of options and likewise, problems. Lol.

[@Jrojan]

I would love to see a out of the box bw366 comparison as well!

[@evil_me]

Any chance you can give exhaust manifold drive pressure readings for these tests?

[@pddofficial]

We don't have a gauge hooked up yet, but maybe we could do it on future tests. I'm sure drive pressure at 3k RPM is at least 1.5x boost pressure.

[@evil_me]

@@pddofficial it would be a great way to show the efficiency of the turbine side by calculating the pressure delta. Especially with the turbos getting larger in your testing, I have personally seen over a 70hp gain from going to an S400 with a smaller compressor from an S300 due to excessive drive pressure.

[@EastMenloPark1650]

[@briankennedy9644]

Please test the PDD hx super nine 60 and 62 if you can, I would like one of those for my vp44 tow rig and would like to see what rpm they spool at. Thanks for the data, I love these kind of comparisons.

[@redline85k]

A few things, can you guys put numbers on the screen or in the comments of the runs. ie. HX35 @35 psi 1300deg made 350/700 K27 @37 psi 1300 deg made 400/800 Aggressor @ 37 psi 1300 deg made 395/780 Can we get a boost plot of each turbo tested? Some Dyno's have the hook up for it. Can we get drive pressure? Drive pressure is super important as you guys know to health of the HG, exhaust valves, turbo shaft speed and where you're at in the efficiency range of the turbo. Thanks guys. Just looking for more organized data. I love the videos, very informative. Are you guys going to test a SX-E362 with different exhaust housings in the future?

[@What-ic6hp]

Years ago they tested the 362 sxe with different housings. Its on their channel. .7 and .91 i think

[@michaelfraser2614]

What's the difference in the k27 vs xz drop in turbo and which one is better

[@pddofficial]

Not sure what you mean by xz, but the K27 can handle about 450hp and has close to stock spooling. Our Aggressor 60/64 is a great alternative to the K27 as it can handle up to 550hp, but it doesn't spool AS quickly. We'd recommend both options for daily driving.

[@BiffsEquipment]

Another awesome video guys! It’s crazy just how close your new aggressor is with the k27! I can’t wait for the next test because that’s the turbo I was planning to do.. I didn’t want to just toss a 60mm compressor wheel into my hx35 with out milling the turbine housing as well so I could run the larger turbine with the stock 12cm turbine housing of the hx35.. I feel this is a lethal combination.. small turbine housing with a larger compressor, compressor wheel, and turbine .. I’m guessing big power Gains!! Can’t wait for the next test!! 👍🏻

[@BiffsEquipment]

PS.. I loved your test with the air box pulled.. gained 2hp! Sometimes math and science doesn’t equate to the real world.. there can be huge differences between numbers on paper and numbers in the real world and that’s why I like you guys so much.. you guys are the real world!

[@doxnoogle5782]

Gale gets a little carried away for sure but in his defense, youre intercooled, and the guys he bitches about generally arent. I can say from own experience that having a box around the filter to get cool air makes a huge difference for idle torque and under the boost. Cool vid guys, im wondering how different the he351 wheel is from the hx40?

[@hermanR02]

Hi I know this is an older video I just had a question about you putting a he351 wheel on and hx 35. So you machine the compressor housing and thats it no need to machine the bearing housing? And the wheel just slides on? If so thats pretty cool and I may do that

To be fair you have to close the hood to do the Gale test proper. I know for a fact that on a 2nd gen pulling thru the stock box with holes cut in it and with the thru the fender ring removed I have seen it run 50deg higher egt's versus pulling thru a stock air filter setup on a hard long pull up a hill.

[@73cjproject]

Major difference with the comparison is a gas engine with higher intake air temp versus a boosted diesel engine with a higher intake air temp, the benefit to less restriction in a boosted application outweighs the loss created by 50⁰ hotter temps. Totally different behaviors between those engines.

[@bcbloc02]

@@73cjproject Totally false. I did the thermodynamic math and you would have to reduce the air filter restriction by 5psi to make the same power as just 25deg of cooler intake temp offers assuming you were running 30psi of boost on a 5.9. 5psi of air filter restriction would be one heck of a lot. Been 15 years since I tested it but best I recall a clean stock 2nd gen paper air filter was only about 3 psi of restriction. The change either way is only about 20hp on a 425hp engine. You raise your intake temps 50deg on a 75deg day you are going to kill your power almost 10% that is substantial.

[@73cjproject]

@@bcbloc02 would love to see your data on the dyno with that. And of course their dyno test is done with the hood open because they aren't running down the road at 75-120 mph getting the proper air flow across the radiator and intercooler/ aftercooler.

[@bcbloc02]

@@73cjproject Know where all that hot air off the radiator and intercooler goes when you are going down the road? It all blows right over the airbox. If you trailer one of these trucks heavy you know the floorboard gets hot from all the heat getting air from out under the hood is a huge help.

@@bcbloc02 so you're saying it doesn't go into the charge air cooler that cools the air going into the engine then? Lol

[@nationalperformanceoffroad514]

What the Crip

[@joepatenaude3957]

Do you think that the heat helps expand the exhaust side of the turbo it is cast iron and does expand with heat and could be helping expel the exhaust and would make less boost with more room between the wheel and housing and the hot air is less dense in the charge system which helps also but it is just a thought

[@73cjproject]

I'm guessing the heat is helping close the piston to wall on the 410k mile engine lol

[@chloehennessey6813]

Love the way you guys did this. Just one point. Don’t just say “huge power numbers”. What might be a huge number to me won’t be the same huge number to you. I’m a turbine girl so huge power to me is 50,000 shaft HP (Navy DDGs for instance) Did the wheel do 1,000? 1,500? If we know what your products do and are capable of were more likely to buy them. P.S I hope Matt over at OffTheRanch calls you guys for a collaboration. He’s got that common rail he calls Earl for towing.

It would be cool to see turban, I mean turbine shaft speeds on these.. but dyno numbers are already a good start

Isn't the main reason you can get more power from an HE351 because it has a much better wastegate than the hx35?
