Hook a trailer to all of them with the same weight. Take them on the same hill and collect egt, coolant, and boost readings over the pull. Then swap to a ported head and do all the same test. Then a bench pump and repeat all the same tests. And if you would want to also throw a towing compound set on top of the aggressor turbos I think that would also be great info and a great video.

[@DJT609]

COMPOUNDS! Add a compound setup to compare to all of these turbos for those of us that want to compare and ultimate towing setup to a single turbo upgrade

[@matty8272]

@@pddofficial I should clarify for the masses. The turbo is working great. It's just a little oversized for my power level. That little delay in spool takes a bit of getting used to but once it spools as the data shows it's a work horse. Personally after having the hx35 for twenty years it still catches me off guard from time to time.

[@jestonjump5647]

Great vid

[@Not_Built-Right]

I have a k27 and after having teething issues with it and a replacement of it i seriously cannot complain whatsoever. I only have a baby just under 300 hp on tap but the torque is a whopping 860 ftlb and that is where it counts towing is a breeze,actually astounding with lowish egt's and very happy indeed .

Just put a 62/65/14 on my 5 speed first gen with 5x.012 injectors, and although the waste gate needs adjusted. She rips!

PLEASE PLEASE PLEASE PLEASE do a low rpm loaded simulation, I would love to see what happens if someone slows down in front of you and you pull down to 1,500 rpm and then get back in the fuel to pass without dropping a gear

[@terrelbrady8035]

Great video Todd! really good info and very well presented. I was disappointed you didn't have a any he351 based hotside in this shootout. I'm running a holset 60/67/9 12 blade. maybe the 60/64 would be very similar?

[@pddofficial]

I love the 351 hot side. The 60/64 is a great drop in but I do like the 67 wheel in the 9cm housing a lot

[@TheRitchieLeeShow]

Thanks I want one.

[@burrito4x4]

Love to see the 62 with a 9cm housing swap!

[@taydanbarker788]

I have your s362/68 and I love it. Not for the faint of heart for towing 15k around the mountains, but after a driving style change it was a night and day difference from the hx35 holding speed and keeping cool up steep grades

[@pddofficial]

Totally agree!

[@bcbloc02]

Maybe for egt testing you should pick an rpm say 2300 and apply a steady load like 350hp and see what charger can pull that same load same speed the coolest. I think that best represents what you typically see pulling a heavy trailer up a grade normally you are just running a small rpm window of maybe 200rpm on the highway. I think you should test the s300g too. I think it would spool about like the 60-64 but have durability like the s300 and the lower egts of the 62. Big drawback to it is the 57wheel is awesome for 450 and down but at 500 it is pretty well tapped out. That is what I have found after doing extensive testing of h1c,hx35,hx40,s300g and sxe300 turbos. This of course applies only to 5.9 trucks. Add cubes like a 6.7 and the 62 is far more favorable. Also why didn't you test the 60-67 Super 9?

[@daviddroescher]

They said they can sim a grade and very the tow rig weight with the dyno when I ran my 91.5. I hope the new Mustang software update retains this functionality, this is the test most need for nontrack use proper turbo sizing choice.

[@pddofficial]

Those other turbos will be in a future video

[@stowaway475]

I wanna see you guys do a comparison of a Borg s369 and a eBay gt45 cause you guys have a Dyno and look at the specs on both turbos I'm just curious on the power out put of the two and how they compare

[@markgummo9624]

I was able to do a few runs up through the gears and measured 60psi of back pressure at 27psi of boost on a 2.5 4 cylinder shifting around 7200rpm with the HE 351cw.

[@cs-gj3yf]

can you do a video on different compressor wheels? say a billet 5 or 6 blade vs a 9 or a 10 blade compressor wheel?

[@jerm45coltg19]

Awesome data!! I want to see how different a ported head is

[@pddofficial]

Coming soon!

[@markgummo9624]

Very good test information. Have you tested the Holset HE351cw non vgt for drive pressure?

[@pddofficial]

Will be doing that soon

[@stevev4302]

My goal is to make 550-600 hp with decent fuel mileage and good towability. And of course i want it the most reasonable way possible. I will volunteer my stock, 77 3500, 5peed dualy with 164k and pay for all the parts. You pick the parts, I'll do the work and you do a before and after dyno run.

[@HolderBlake]

Are we going to see the Hx super 9 on the comparison? Interested how that one does with the different compressor wheels. Been very interested in that one. Would be great to see a simulation of loaded, off throttle and hit the power to simulate passing on the highway.

[@M-FE]

Wish I would have waited when I bought my bd killer b s361 for my 06 . Maybe next time

[@Precisionmobile]

i am on a quest for the best mpg in my 97 180 pump service truck shes mostly stock except mild trans and 4k gsk 4 inch turbo back got right much weight in the bed and shes getting a little lazy and i havent even added my compressor or generator yet

[@landoncholly]

i have the 62/65, 5x16s, 025s, 160 pump and still on stock gov springs. can hit 43psi and 1150egt unloaded on the highway. 30-80 mph time is similar to my old 30-65 mph time. i need to spend some time tuning and put my gov springs in.

[@pddofficial]

I have a video coming where we picked up 400 hp from tuning. Is a high power truck but spending time dialing something in is time well spent

I wish you guys would play with the 6.7 Cummins. Off road use only, of course.

[@pddofficial]

Unfortunately if it ever had a vin # there is no such thing.

[@VR6ix]

Would love to see what a Stage 1 PDD ported head would do on that exact same test with the 4 different turbos and no other changes

[@bcbloc02]

Mainly it will lower the boost and increase the drive pressure across the board. This will of course allow the bigger chargers to behave better and likely make some more power and on the small chargers it will aid spoolup but probably not power because the turbos already can't flow enough air.

[@gmjason75]

I have your 60/64 on a 24V 6-speed and like it. Which of your intercoolers do you recommend? There is some evidence of the beginning of a stock radiator leak, so I will change that also.

[@pddofficial]

The mishimoto is a good unit. A bit restrictive at 100 pounds of boost though.

[@Dono.N]

I have been curious about intake flow, the banks twin ram is something I would be interested to see if it makes any differences in these numbers. There's a lot of nay sayers on intake flow but Gale Banks has some interesting things to say about the matter. This would settle the issue if we could get a non biased data set.

You said it. No one pulls in this RPM. So most of this data doesn't apply. Then why not look at the torque as its in those drive ability ranges. Ill take torque down low & early every time over hp. HP #'s mean nothing to me. I never hit those RPMs. But i do want better power how I use it.

Fewer valves doesn’t bottleneck your performance?

[@pddofficial]

That is an ongoing debate here for sure. 4 valve heads flow way better at lower lifts then stall out quick. 2 valve heads just keep picking up flow with lift. Both can be made to work well but probably easier with the 4 valve heads

1000rpm difference in spool for 50 more hp at the higher rpm? seems like a win to me

It would seem that way until you actually drive the two particularly if it’s a stick truck. In that 1250rpm to 1750 rpm range my 57mm s300g has instantly available about 160hp. The sxe362 in the same range only makes about 100hp.
