Snakehead Shape Is the Secret to Power Stroke Success

IMG_3435a II

What's the secret to Ford's 2015 Power Stroke's horsepower and torque success? Apparently, according to a press release, it's the shape of the exhaust down pipe that has a vague resemblance to the head of a king cobra snake when it's ready to strike.

The new Power Stroke engine is the undisputed leader in the horsepower and torque war in the heavy-duty pickup truck segment, with a Society of Automotive Engineers-rated 440 hp and 860 pounds-feet of torque from the 6.7-liter compacted graphite V-8 block. Although there were many changes to the 2015 turbo-diesel, one of the biggest changes responsible for those big numbers came from the 90-degree bend at the turbo-exhaust outlet. This, the engineers tell us, is one of the biggest reasons the horsepower and torque numbers climbed so dramatically from the previous 400/800 ratings.

Whether this means we'll see more animal- or reptile-shaped engine parts from Ford remains to be seen. However, if advance fluid dynamics computer modeling theories indicate that such designs get more torque and fuel economy from turbo-diesel engines, we don't have a problem with an air cleaner box that looks like an armadillo.

With the price of these diesel pickups topping 70k, a mere 30 grand more you can get a Peterbilt 389 or Kenworth W900 tractor and you can really be the big dog towing king all day long and never worry about being one upped

@greenrover - and the Pete will last 3 times as long.

Very true Lou! All the big diesels still use pushrods, though I remember reading the next Cummins upgrade might do DOHC. I am taking that with a grain of salt!

I am perplexed !
I love my Ford Dealer
I hate my Ford Truck!
I believe Ford went the wrong way changing their truck.
Ford doesn't listen to what the average guy wants, half of the guys that post messages here in PUTC could do a much better job designing the Ford.
I get harassed by non-Ford owners showing me the weakness in my Ford and the more I listen to them the more I know they are right.
If Ford was smart they would conduct a survey to all the current Ford Truck owners asking us to point out the flaws and how to make it better.

@Tom#3 - if you are traumatized by what people say about your truck maybe you should get a job as a florist.

That closet you are hiding in is getting too small ;)

I would like to thank you Alex, for pointing out the fact that the Duramax has gone threw some substantial mechanical changes since its initial conception in 2001.

To many GM/Duramax fanboys try to argue that the Duramax is a essentially a 13 year old engine that still keeps up with the modern Powerstroke and Cummins when they couldn't be further from the truth.

About the only thing that hasn't changed on the Duramax since its 2001 release is its displacement. Its stayed 6.6L for the past 13 years but its evolved enough over the years that it's just asinine to try and say a 2001 6.6L and a 2015 6.6L are the same engine, displacement aside they are two very different engines.

I mean lets look at it like this...If the Duramax were truly a 13 year old engine competing with modern diesels like the 6.7L Powerstroke/Cummins, than I think PUTC should get their hands on a stock 2001 Duramax and compare it head to head with a 2015 Powerstroke and Cummins, and lets just see how the results come out.

Anyone who thinks the 300hp/520lb/ft 2001 Duramax stands a snowballs chance in hell against a 440hp/860lb/ft 2015 Powerstroke or a 350hp/850lb/ft Cummins ''especially in towing comparisons'' is seriously delusional.

And for the record im not bashing the Duramax, I am a Ford guy above all else, gas/diesel/car/truck...etc...etc. But I give credit where its due. The 2001 Duramax was essentially the diesel engine that sparked the Diesel horsepower and torque wars, which essentially led up to us having the monstrously powerful diesel engines we have today, and back in 2001 neither Ford nor Dodge had an engine that could compete with Duramax, the 7.3L Powerstroke, while reliable as hell, didn't have the power or torque to keep up with the Duramax loaded or unloaded, same can be said of the Cummins from those days. So believe me when I say this isn't about bashing the Duramax, If anything I'm just bashing unreasonable fanboys who refuse to take off their blinders and spread false information as if its cold hard fact.

So once again, Thank you Alex for pointing out that a 2001 Duramax and a 2015 Duramax are vastly different engines aside from displacement.

The headline for this story is dreadfully misleading... should say "Gimmicky Technology In Real World Testing Still Cant Beat 11 year old Engine with over 100ftlbs less torque"


What story did you read? Ford beat them all in Performance.

@Nate,

Only TROLLS like to spin it that way, The Ford SuperDuty, they say it's the same truck since '99, but when it beats their new trucks they are quiet. Now they say the Duramax is the same engine, they raise their poms-poms.

I'd say, let the ladies have their fun.

Catapillar and euro truck maker Mann helped ford deaign the 6.7 engine FYI. I trust those two sources input. Catapillar only helped ford because they Stopped making small and medium duty truck engines because the market share wasn't there.

Anyone happen to know why the scorpion 2 engine on the chassis cab still has the low output rating. I called ford to find out if the f350 diesel chassis cab and f350 pickup diesel were identical and they said exactly the same but tuned differently because the chassis cabs will most likely always have heavy payloads in them and it's done it increase reliability....I can't wait until they come out with a tuner for the 2015 6.7 f350 chassis can model. They also said it had something to do with rear end ratios but I think that is BS. I wish I could see a chassis can 6.7 next to a pickup 6.7, and the turbo part numbers for each to ensure they are indeed the same. I was so pissed when I got my 2015 CC f350 because I thought it had the extra power...boy was I wrong when I saw the 300hp rating when I lifted the hood and looked at the engine specs plate.! Ford for our company has been a good product. The real issue lies with the crappy service the dealers provide and not having good diesel techs. I'm still looking for a central NJ diesel tech that I can trust.
