These guys are awesome. When they say call and they will help you out they mean it. I called to ask about what to look for in buying a used truck and the guy I talked to was super helpful and very friendly. I'm very glad I called because I was looking at a different style truck and they gave me some great information. I have since purchased a truck and can't wait to start adding some PDD components. Once again thanks guys for all your help and advice. Hopefully someday we will be able to make the trip out there to see your place in person. Curious do you all have anything planned for the 68rfe?
Sweet. I was really hoping that I could get something that you all had done for my truck. I was looking for an older truck but when this came along with only 118k and in my price range I just couldn't pass it up. Super excited to know that you all will be putting out some products for it.
I am a disabled vet and love your videos. I have a 2006 5.9 (my first dodge) better than my old GMC. Keep up the good work. When I get out to Utah, I look you boys up. God bless
Sir, They are located in cedar City, Utah. you can go online and research "Power Driven Diesel", and will take you to the website go to the menu, click on "CONTACT US" and you will see their address on the bottom. Thanks for your service, & Between I have a 06 Cummins too.
Hi, I have a 460whp stock fueled 110k mile 03 6 speed with a Smarty, Raptor lift pump, 3250DD clutch and a s366 that I removed to pass emissions. Now that I've moved to a place that doesn't test do you think I would see a noticeable difference in spool up by upgrading the exhaust manifold when I go to re-install it in addition a turbine blanket or do you think I should continue to save my money for other stuff like fueling mods, custom tuning or stock/s400 compounds? Thanks
Thanks for your videos. I am just learning about the b series. You say broken ears know the head? I dont see any Ears on the head. Now cast iron exhaust manifolds can break ears. That 3 piece manifold cam out in the 50,s on 855 cummins 14 liter engine. Never seen on of those break ears. The head studs are a loose fit in the holes on the manifold, so they can move longutudily!
Twin scroll turbo exhaust manifold and turbo inlet also stop pressure starvation. With each exhaust valve opens it's creates pressure pulses and cycles of higher and lower air pressure when the valve closes that pressure pulse can go backwards. When you get up to higher rpms your getting more pressure pulses and higher chances of that pressure wanting to go backwards. With the twin scroll it eliminates this
just my 2 cent thoughts. please correct me if I'm wrong. ok. The 2nd gen swap on 3rd gen is a big plus in my book. equal runner lengths throughout the firing ordet should balance the "pulse". that balance should help pull heat away from the problematic back three cyliders. in theory should create a smoother exhaust flow witch possibly could help with spool up. to me it's not necessarily a HP thing but an efficiency / support thing. plus on compounds things just fit better with less piping. I've seen multiple mild tune towing trucks die due to heat in 4 and 5 on 3rd gen. never seen that in 2nd gen truck. So a 2nd gen swap just makes sense to me. thanks todd
Is it ever done, a smaller T3 manifold with an adapter into a T4 turbo to help increase exhaust velocity. Ever since I’ve upgraded bd 3 piece and S362, Super slow spool up. I think I’ll be giving you a call Todd to get this figured out.
Really great video! Also, phenomenal to see the divider in the steedspeed manifold sealing up against the wastegate valve. We've fabricated many manifolds (4g63) with a single but divided path to the wastegate, and saw a significant loss in response and boost threshold with even a small path for cross talk without the full divider. Good stuff
and another thought. how does going from t3 to t4 effect spool?? t4 you gain volume but loose velocity. and in a compound set up with 362/363 with 475/480.
You do loose exhaust velocity. You'd need a larger camshaft, head work done, and valve springs to spin up past 4,000 Rpm to run larger exhaust housing compound turbos. Typically though, S362 with S475 shouldn't need that.
Just an fyi for anyone interested, my 05 came with an open manifold, my early 04 had a divided manifold. I don't know if they chose to open it when they introduced the he351 in 04.5. But my 04 definitely had a divided manny with an open he341.
Logan Paris Get a new one or try to have it welded Probably better putting the money toward a new one with a warranty Should also replace all the mounting hardware Good luck
Rebuilding a stock 5.9 common rail due to having cracked rings. Would an after market exhaust manifold help stop that from happening again? I'm not looking for power just reliability. Thank you for the videos.
I just rebuilt my 06 cr due to cracked rings I'm putting on a dps manifold supposed to reduce rear cylinder heat by 200 degrees and they seem to have good reviews. will see seems like the stock manifolds on 3rd gens have crappy flow from the rear cylinders my 5 and 6 run hotter than the rest with stock manifold by like 100+ degrees according to my heat gun after towing so gonna try a dps out. It was my 5 and 6 cylinders that had the cracked rings so worth a shot.
Todd , I just Subscribed. Before watching your channel I had no clue why it was so important to choose the right type of exhaust manifolds for turbos . You made it so interesting and informative and explained it in such great detail . So Thank you for making and preparing this video.
Always look forward to the Power Driven videos. Even though exhaust manifolds are not always directly related to more power in the overall recipe, it's a critical upgrade once a certain power level is achieved. Even for the seasoned diesel enthusiast, this video is a great refresher as to why we spend our hard earned money on such upgrades.
Twin scroll improve lag and reduce the pulse scavenging, if you brace Tha splinter part its because your egts are higher then they should be, you have rolling coal
How can you flow enough air thru those little manifold outlets to make that big power? Obviously you can, but it doesn't make sense to my small brain lol. That would strangle a gas engine. Love the channel, I'm trying to do a 12v swap on my blown up ( shocking I know lol )08 F250 6.4 truck Good info here 👍
ok. my thought on 3rd gen to 2nd gen ex man swap is not neccasarily performance but it is at the same time.... equal runner length equally diveded should give a more iniform exhaust pressure, more equal ex temps and supply a more even "pulse" to the turbo. while hp numbers may not go up...efficiently (spool) should and really help with 3rd gen problems of killing #4 & 5 pistons. would love your feedback
On my 03 Dodge Ram. The manifold had a diviner and the turbo didn’t . It’s a stock manifold and it was a stock he341. I now have a holset cheetah turbo base off a he351 and it also didn’t have a divider in the exhaust housing.
I take it by diverter valves you mean like a quick spool valve. Splitting the scrolls in a turbo. Have you had much success with them? We use them in the merc diesel tuning scene and have had 800-1000 rpm quicker spool times. And less restriction than a true twin scroll manifold
hey todd in your opinion would it be worth self porting/polishing a stock manifold and where would the best place be to tap for egt sending unit 5.9 24v
Rear of the two outlets that go to turbo is the best place to put the prob. Gasket matching stock manifold would help a little. Not enough to notice by seat of the pants tho due to your not really changing to flow inside the manifold.
From personal experience dont go stainless. It expands an contracts moreso then the other metals. Cracked one in under 6 months. Have pdd one for over year no issues. Bought another for my other second gen now
Have First second gen p/pumped (bone stock) shortly after shutdown there is a "cooling pop"sound numerous times equally spaced of approximately every 3m or thereabouts, over what I'm sure is until cool enough (I've never hung around the complete cycle to time it ceases) 1 is that the manifold receding back to cooled "sizing" and is it something of concern anyone? Thanks in advance.
I've got a mostly stock 12 valve that needs a new manifold. Does the Steed Speed hold up long term? Just based on the material and construction, I'd imagine it's the best I can get... thoughts anyone? :)
They Steed Speed manifolds are excellent. The ceramic coating wears/flakes quickly in bad weather climates, but the structural integrity of the manifold is excellent.
This video got me thinking about pyrometer probes. On the factory divided manifold, where do you recommend Drilling and tapping? Since it's a divided manifold, aren't you just monitoring three of the cylinders exhaust temperatures by just having one side or the other?
I think those housings would be quite nice to be tested since they are commonly available. On gasoline world some have reported 300-500rpm earlier spooling and bit higher power output. that would be actually quite a big thing in diesel application
@@pddofficial I've got a 63/68 s300 on it right now, it'll probably get p pumped and compounds eventually. Is there anything that's kind of in between the stock manifold and steed speeds?
Good video thank you I have a 2006 Dodge Ram 3500 single wheel Cummins stock Turbo smarty jr. 5 inch exhaust cold air intake turbo Rings been moved and aftermarket elbow intake I was wanting to put an exhaust manifold on my truck just for maybe making the et's a little cooler should I put one on what one would you recommend or should I just leave it alone and I have a Boost fooler on it and the transmission is stock automatic
So I went with an ATS manifold on my truck when the original warped and began to leak. Over all my egts didnt seem to drop drastically (maybe 100 degrees give or take.) On the top end but they did seem to reduce alot faster overall when I let out of it. I also have noticed faster spool up and an overall more even powerband. Hope this helps.
