1st comment! I did a full gasket rebuild kit and new clutch on a 24v with 370k miles I just bought. These guy were amazing. Whenever I had questions they answered the phone and helped. Great products. Great support. This is how business should be run. Thanks guys!
About time somebody else had some damn sense. Aluminum i imagine, would/does make the head gasket problems worse, but weight loss is power gained. If someone could get the engine package from 1000 pounds to say 700ish, reliable during performance use, the Cummins platform would be exploited by more racers and enthusiast. Theres been billet everything but cast parts from manufactures you mentioned is required to bring the cost down to a level to bring to the mainstream.
Good video. I remember years ago on my 5.9CR with s363/s483 with 200% going from stock cam and head to ported head and 188/220 it was crazy how different it was.
I'm getting ready to start putting together another engine for my car, Volkswagen 1.9 TDI but all the same theories apply. It's started taking a liking to the 5-6000 RPM range so I think it's time for a better cam and ported head lol.
What kind of gains do y'all think would be had with a baby turbo? I have a 63/73 he351 on my pull truck and feel a head would be a huge step up Edit for typo
The peak power difference would not be as dramatic but the difference as rpm climbs is always there no matter what turbo. I would think a pull truck that spends most of its time at high rpm would be the ultimate candidate for a ported head!
I am curious as to what would happen on a stock cam and only slightly higher fuel rate in a towing/work truck scenario, the numbers look like these same effects would work just as well for fuel mileage and towing with minimal other upgrades.
I haven’t tested fuel mileage specifically because usually more mods come when people do a ported head. I will say that they make more power everywhere and with less boost so efficiency is up. I am up 2 mpg on my red 1500 horse mega but I also put in total seal gapless rings so i can’t say definitively that the head made the difference but i think it definitely helps!
I have a 2003 5.9 that is blown. If I put in a 6.7 do I have to change the computer? I have all gale banks setup on the 5.9 with the 6 gun, bigger intercooler and a Phatshaft turbo with full 4 inch exhaust. Thoughts??
Since I have now learned that swirl is important to the power of 14, what about combining that with the Speed of Air pistons? Could we get the Swirl importance to the power of 15?😂
I haven't seen combustion analysis results with the dimples even though 2 shops said they were doing combustion analysis. I'm guessing it was a disappointment and swept under the rug.
I'll give you guys a shout to discuss. I do think there's a market for a ported ISX head and since there's not a shelf on the head like the light duty engines it would be a pretty straight forward op.
Lean is a relatively vague term. Technically 15:1 is lean and will actually have quite a bit of visible smoke and will be hot. 30:1 is also lean and will be transparent crystal clear and much lower EGT/overall temperature. Generally 18:1 to 20:1 range is hottest on the race trucks, leaner than 22:1 starts to cool off, richer than 14:1 starts to cool off.
@@gadsdenconsulting7126 took them months and multiple attempts to get my core return back. bought an upgraded oil pump that had obviously been used and returned. I had to have it or I would have sent it back. Head stud nuts didn’t fully contact the studs. when contacted they said it was fine, then I contacted their head stud supplier and he was upset that they said it was fine and he sent me the correct studs. Had issues with injectors and they never responded. I very much doubt it is the guys on the channel doing this, I fully think their customer service just sucks.
One in every crowd. Maybe try calling them if you have problems vs trying to ruin a company on the internet dip shit. Takes a real scumbag to do that to a company, especially like PDD. Anybody that has followed Will and Todd from the get go, knows better. Shit can happen and this is not the way to deal with it.
Biggest bottleneck on diesels is the intake and exhaust manifolds, then the exhaust piping. However, everyone seems too cheap and/or stupid to cast high-flow manifolds with equal-length runners on them.
Would be easier to understand what happens if you didnt call it drive pressure. Pressure is not driving anything, it is mass flow of exhaust gases that spins turbocharger.
Ya know what sucks? The 7.3l Ford diesel sucks! It is the biggest diesel for regular consumers yet it is also the WEAKEST! I've had over 50 cars & truck, never a diesel because I couldn't afford one. Finally I bought an 86 F350 that the previous owner blew up the 6.9 & replaced it with a turbocharged 7.3 from a 1990 E 350. I got it for a good price & I thought, WOW, I finally have a 7.3L monster! I don't know jack about diesel's except that they make tons of torque, or at least the smaller diesel's do anyway. My son started looking up torque specs for other diesels & all the smaller diesels put the big fat 7.3 to shame!! What in the hell is the point of a 7.3L when all the smaller diesels kick it's ass?! This really really gets under my skin! why make a big ol' fish like the 7.3 when even a 5.9 SIX CYLINDER kicks it's ass in a pulling match?! I mean damn it, my 7.3 has 2 more cylinders & it is a weak lame ass duck??? I don't care at all about the horsepower, I want my diesel to be a barney badass torque monster making 2,000lb ft of torque or more but instead of have the weakest damn diesel on the market. Why does International even make such a wimpy lame ass duck like that? Since I don't know a damn thing about diesels what would be the best way to bring the torque ratings up in this pathetically weak & very lame duck? Again, I don't care about horsepower, if I want to go fast I will get in my yukon with it's 6 liter ls engine, I just want TORQUE!
You bought the wrong year. You need direct injection 7.3 2002 with all the parts . Custom tuning,big turbo 180 cc injectors. It will make the power and torque of 2018 diesels
Yah the idi international was a giant turd. My dad had the last year 93 turbo and what a giant turd. You need a 94-02 if you want more. But even those are turds in comparison to a Cummins. They make lots of noise, but go nowhere fast. They will pull just about anything though, and get good mileage doing it.

Thanks for the kind words and the support!
Swirl is so important , I have been swirl porting since the mid 80 s !
Heck yeah!
I LOVE reading old post on comp D from Will and Todd. All the technical mumbo jumbo. Great video.
I love compd! I need to hang out there again.
Todf
Compd thats a blast from the past!
Love Todd’s magic floating head 😂 Great video great Data, keep it up!
Awesome content! Best diesel content on the net! Keep it up guys!!! 👍🇺🇸👍🇺🇸👍🇺🇸
Glad to see the dyno is back up and running.
AWESOME INFO!!!!!!! Love it, PDD is the best in the biz and they show the data to prove it!! keep it up and cant wait for more!!!!
Thanks David!
I would love to see a video this style, playing with cam intake center line.
I love the videos thank you so much for everything you do and thank you for letting me win those compound turbos “Swirl “❤❤❤❤
Heck yeah! Always fun to hear from a winner!
Very informative and zero BS. I wish more automotive content was like this!
Love the videos!
Be great to see the after market head makers build a true performance head for the Cummins.. Just as Air Research, Brodix.. Etc

Great info video. The swirl counter was killing me! lol
Really wanted to drive that point home!
Good video. I remember years ago on my 5.9CR with s363/s483 with 200% going from stock cam and head to ported head and 188/220 it was crazy how different it was.
Ported heads really make a HUGE difference!
I "WANT" that motor in my truck. Amazing!

Nice, you’ll have a screamer!
Love The Data Videos!
I bet this thing makes more power on the track. Tons more air moving across the CAC on the track vs that fan you have. Very good gains here.
great info. looking forward to the next vids. 👍
What kind of gains do y'all think would be had with a baby turbo? I have a 63/73 he351 on my pull truck and feel a head would be a huge step up

These are the videos that I like to see! I like to see the numbers! There's the truck sound any different being ported?
Well hopefully my home garage or backyard port job works good on the 6.7 head I put on my 5.9
Was the turbine housing T6 or T4 and what was the a/r? Love this video. Love technical data. Keep em coming.
T6 divided 1.15 housing👍
Shows now the exhaust set up is making back pressure
I am curious as to what would happen on a stock cam and only slightly higher fuel rate in a towing/work truck scenario, the numbers look like these same effects would work just as well for fuel mileage and towing with minimal other upgrades.
I haven’t tested fuel mileage specifically because usually more mods come when people do a ported head. I will say that they make more power everywhere and with less boost so efficiency is up. I am up 2 mpg on my red 1500 horse mega but I also put in total seal gapless rings so i can’t say definitively that the head made the difference but i think it definitely helps!

You ecm will work fine if you put a 6.7 in.
I'm curious about mpg. Theoretically the more efficient head should do better?
I would agree but I have not done testing on that yet
Dose just a posted head make that big of a difference or dose the came have something to do with how well the ported head flowed
We had the same cam for both heads.
Why did y’all hot torque the studs.
It tends to give us more crush on the fire rings.
Great vidoe
Since I have now learned that swirl is important to the power of 14, what about combining that with the Speed of Air pistons? Could we get the Swirl importance to the power of 15?😂
lol! Maybe?!
Don't waste your money on those pistons. Put into a turbo or ported head
I haven't seen combustion analysis results with the dimples even though 2 shops said they were doing combustion analysis. I'm guessing it was a disappointment and swept under the rug.
@@hankclingingsmith8707- All 3 mods are best!
@@danieljacobsen7196yeah, where is the actual data for before and after with no other mods
Can I ship you my OEM 6.7 head for porting and bigger valves or do you have to purchase new
as of right now we the machine is booked up doing ports on new heads. We may offer that service in the future if there is enough demand.
I want 1😁
They are awesome! My tow truck Ruby has the same port design and I can’t believe how easy I can drive a 467/gt55 at 6000 feet elevation and higher
Gale Banks does not approve of this message. 😂
Who cares, these are real # not just oh wow # oh my product gained 15% more air flow❤
@@BeverlyHolzworth My point exactly, Bev🤙🤙
Banks is a salesman......hack.
Would love to pick your brains on building my engines. Im a bit cummins crazy... total of 9 but only 5 need rebuilt.
Give us a call, we'd love to talk to you! (435)962-9555
Are you guys able to port an ISX15 single cam head?
Could you put a tape measure on the head, how long is it? A C15 head is 43" long for example.
Right at 41" longest point to longest point.
Do you think there would be demand for ported big rig heads?
I'll give you guys a shout to discuss. I do think there's a market for a ported ISX head and since there's not a shelf on the head like the light duty engines it would be a pretty straight forward op.
NERD FOOD, Delicious!
Heck yeah!
Not quenching but washing cylinder 😂
I would love to see direct nitrous oxide injection through a glow plug hole in a cylinder and see what effect it would have on performance.
I have a brand new head but now I want to port it :(. Any chance you guys can port mine?
We currently have ports made for 12v and 24v Cummins and 6.0 PowerStroke heads, if you have one of those platforms, we can port it!
Kinda wish youd have showed us what was done. Didnt really learn anything here.
Do it😊
Now do a stock vs a mild-daily driver cam from, say, Hamilton Cams.
Somewhat kidding - that might be quite a bit of labor/work.
🔥😎🇺🇸
Yolls swirlymeter aint counted 2 of em. Had the same dill goin witha '21 Raymond not counting lift cycles. Proly sh'ty covid parts lol
Lean is hot on a diesel? I dunno...
Lean is a relatively vague term. Technically 15:1 is lean and will actually have quite a bit of visible smoke and will be hot. 30:1 is also lean and will be transparent crystal clear and much lower EGT/overall temperature. Generally 18:1 to 20:1 range is hottest on the race trucks, leaner than 22:1 starts to cool off, richer than 14:1 starts to cool off.
@pddofficial
I see what you meant in the video now. I had no idea it cooled down at any point after it starts smoking.
Thanks for the reply
First
Their customer service has gone way down hill…
What? Please explain.
@@gadsdenconsulting7126 took them months and multiple attempts to get my core return back.
bought an upgraded oil pump that had obviously been used and returned. I had to have it or I would have sent it back.
Head stud nuts didn’t fully contact the studs. when contacted they said it was fine, then I contacted their head stud supplier and he was upset that they said it was fine and he sent me the correct studs.
Had issues with injectors and they never responded.
I very much doubt it is the guys on the channel doing this, I fully think their customer service just sucks.
Curious as well about this.

I order from them regularly and I disagree!

No they are not, usually they flow very well. Equal length is not for turbos.
