Where are you getting your info from? I talked to the guys that made these pictures public, and when I talked to them as of last week it was 2 engines that were windowed not 3 or 4. They also said they used a canned tune, and that specific tuning for their setup was required but was not complete. I have a turbo Mustang, I had a fully forged motor that was completely capable of holding 900 RWHP but the tuner smoked it when he messed up timing and air/fuel ratios. It was only making in the area of 780 HP when it let go, but after investigation there was 22lbs of boost at 32 degrees of timing and the air fuel was in the 13:1 area on 93 octane. Call SPE, they are a stand up operation and they will explain exactly what happened. Unless we've torn these motors down personally we should hold off on speculation and premature judgement and allow the experts to pass the info in a precise and accurate manner.
I got the info from SPE source before they were posted on facebook..... I just noticed they were made public and nobody had posted them, so why not.
my source told me it was 3 or 4 engines, not 2... and that they all let go @ 575-600.
That is the only info I have. They also said they are putting off on building another 6.7 until either Carillo or Crower make some rods (they are working with both companies to try and make it happen)
You can go to SPE's facebook page and read more about it, I haven't personally spoken with SPE, just heard about it a bit before they made it public.....all of my info was second hand.
This carnage looks very similar to the carnage from the Industrial twin setup that blew apart -- actually I think that was a bit worse.
As TurboDiesel stated, it's all speculation at this point. While it's easy to point the finger at Ford for building a 'weak' motor, there are so many variables in this equation. It'd be nice to know more about the tune, boost logs, afr, etc. Until we have some solid facts which back up these 'weak' motors, it's all speculation...
Personally, I'd like to know more about what tune(s) these motors are running and what sort of boost levels they're running with the compound setups. Well, at least someone can make a coffee table out of the short block...
If I remember right from my conversation with SPE, it was 60lbs of boost with a canned tune from H&S. They didn't have a custom tune, they used the tune used for the stock turbo setup. The truck was making max TQ below 1800rpm!
The turbo bearing problems can be worked around, as well as the injection volume if someone wanted to spend a ton of rebuilding and re-plumbing money. If the rods are weak under pressure of higher boost, then it's an even worse engine than the 6.0L ever dreamed of being. I guess the good old days are gone. My 6.4L lives at 50+, and is not for sale.....
Too bad there isn't an "I told you so" Smiley.. Ford built and designed this thing to fail under aftermarket pressure.
These 6.7's are cracking cranks and frying rod bearings with a stock calibration. Mahle makes the rods. I would hold off on building large horse power 6.7's until the after market companies supply more parts.
Does anyone else have an issue with this post in general? I'm sorry but I got a troll vibe from it. The fact that he said 3-4 engines and he reposted OLD pictures is suspicious to me. I am so tired of people looking for stuff to go wrong. And George I normally respect what you have to say, but man are you ever going to give it a rest? If I didn't know any better you would be someone from a dodge forum that just comes here to bad mouth a ford engine... Anyway back on topic, if I see one more post about the compound kit blowing a motor I am getting off this forum. It's all negative here. All negative.
It's sad that most of you guys can't live with 500hp/1100ftlbs with a tune and delete. It's a 1ton truck. If you wanna race buy a friggin mustang/camero/challenger. I'm more then happy with the get up n go I got and how it pulls any trailer with easy
Could not have said it any better myself. These trucks are not made to set track records... I was at the Ennis Diesel nationals two weeks ago and i saw some fast trucks i will admit, but i also attended Fun Ford weekend in baytown and almost every mustang there was running 10s... and almost every diesel truck at ennis was struggling to get past 13s...
George, you are wrong... With a bad tune and extra boost the 6.4 would also let go, it's a simple concept. Yes the 6.4 is a great easy to mod engine, but the 6.7 has better heads, better block material (CGI), and overall its more efficient. Ford did a great job... Like I stated before I had an expensive engine in my Mustang, but a brilliant (insert sarcasm) tuner destroyed a very nice setup by messing up a few crucial parts of the tune. SPE used a canned tune, it wasn't meant for their setup, with the different injectors and the compound turbo. SPE did say they had never seen a diesel engine that spooled and made power so quickly! Despite the setbacks they had a lot of praise for the 6.7! I imagine your 6.4 is very nice, but if you don't own a 6.7 and you've not messed with the internal architecture how can you be so negatively biased? I love my truck much more than I liked the last model, but I will give credit where it's due, the 6.4 is one of the easiest engines to make tons of bolt on power with!
I currently work at a ford dealership and work on diesels 90% of the time. 6.0's and 6.4's keep us very very busy, and still do. Always something going on with them. But the 6.7.... Well we haven't even seen but 4. 2 turbos and 2 motors(C&C). I honestly wish they would break down so we could have something to do. Lol
But honestly, I think ford got sick of warranting tuned trucks and what not, they did this on purpose. These are meant to be a strong reliable STOCK truck.
Don't tell George C that. We have the same experience at our dealer. I asked one of the diesel techs what he was going to do when the 6.0 and 6.4 are gone he just laughed.
The makes what 4 now?
2 from spe one with the industrial injection and I rember seing one other with blown rod.
Not starting anything here just asking if I have the number right.
All of them with canned tunes I can see exatly why they blew...
SPE didn't use the industrial injection setup, they used their own design. They had two engines let go... I am not sure about industrial, I never spoke with them. The big problem seems to be the tunes.
If you can comprehend past posts, you will be able to look back and see that I have always believed the 6.7L was a nice bone stock engine. I'm just not a bone stock engine lover. Just as PSR said in his post, I also believe Ford designed an engine that would reject mods, and it is doing a fine job at that..
So, now we all agree...
For every "qualified" opinion from a Ford diesel tech, there are usually others who sees it differently. I am sure the 6.7L will be a very sound engine if left alone. If you like to tune, we may be down to one engine worth owning, the Cummins. The 6.0L wasn't a sound platform, although I didn't have a single problem with my Quad 160 tuned 03'. The 6.4L problems are usually emission related. Strip off the EGR, and strip away problems..
Sorry George , kind of mistook what you said in a few previous posts. I agree with that so far.
