Hell yeah homie. Your up over 1000.
I bet ford wouldn’t mind taking a look at that… maybe they’ll make some improvements. Do you think this would’ve happened to a 2nd gen?
Good question, I’ll address that question in a coming video.
@@BoostKingMatt aw come on I’ll still watch the video but you can still let me know lmao
@@OutdoorCanadians haha, well, the best answer is I don’t know. But I think repeated launches and such would yield the same results. However, I do believe the 10 speed is better for this reason: it keeps rpm up and doesn’t let it dip down as low as the 6 speed does thus it puts less strain on the engine.
What mostly happened was pre ignition, cylinder ignited before it was suppose to, piston traveling up all of sudden is being forced down bending the rod, happens again shattering the piston and the rest is history
There was no knock (preignition) in any of the datalogs. The truck was running good on e50 (102 octane) fuel
I’m not surprised the knock sensor didn’t pick it up, you said you floored it and it exploded, spinning the engine at 3500-4000rpm everything happened so fast at that rpm
I think the amount of boost you were pushing bent the rods due to too high of cylinder pressure for them to handle. Now we know the weak point once you start pushing them. They're amazing engines. Forged rods and pistons on your next 2.7 build.
Yep, the piston and rods are the weak point on the 2.7L. ZFG Racing sells Forged replacements. Definitely worth looking into if someone wants a reliable 600 WHP+ 2.7L
Agreed. I might do a built 2.7 in the future. 😁
That thing has aluminum block and cylinder heads? It wasnt ment to handle all the fuel and air you pushing in to her..My opinion is that the failure is due to repeated overheating of the 7000 series aluminum. a bigger radiator or less aggressive tune is the way to go
It has a compact graphite iron block with an aluminum piece that slips over top. It’s a two piece block. Cylinder heads are aluminum yes. The aluminum did not break, it was the rods that failed not the block lol. Also I don’t know where you got 7000 series aluminum from, did you check that with Ford? A bigger radiator won’t solve anything whatsoever. Friends of mine running even more power haven’t had issues with that.
I did not check with ford on this specifically but 7000 series is the military grade stuff and typically what is used... Just saying, I've seen this before in other vehicles with aluminum engine parts after they get moded. aluminum has the highest thermal expansion of any medal. the piston needs to expand at the same rate as the block for the piston to move freely.just my humble opinion buddy, ill ask my ford mechanic roommate his opinion on it tmrw for you tho!
Do the cylinder walls seem a little too thin for a turbo motor? Great vid, you can definitely see that the rods are the culprit. Not sure if upgrading rods and pistons, plus work, is any better than just going with the 3.5L. Dont get me wrong, a HO 2.7L is pretty amazing, but any motor can be amazing with gobs of money thrown at it. Thanks for the content man!
Well yeah I think most people would just rather put the money into rods and pistons for the 3.5 and then shoot for 1000hp. The 2.7 is capable but would need a lot more boost thrown at it.
In my opinion, which isn't rocket science 🤔. Obviously, the bottom end can't handle that much power. Time to upgrade that bottom end and drop some $$$$(?)😮
The bottom end can hold power, the crank is forged. It’s just the rods and pistons that need to be upgraded.
Yez, zir! You're right. Have you priced the parts yet?
Haha no but it wouldn’t be a ton of money. Costly part would be having someone build it for you, but ideally you’d start with a brand new short block and assemble it yourself then save a bunch of money.
Man this doesnt boost confidence with this 2.7. I just bought a used 2020 with 65k miles and I have already tuned it from mpt performance and added AWE exhaust with AFE Cold Air Intake with a catch can and I am not going to lie this kind of scares the crap out of me.
I would not be scared at all. You are nowhere near the level I was at. I had over 600hp and on e50 fuel and huge custom turbos. You are safe below 500hp
120k on my tuned stage 3 2.7, half of that mileage has been tuned. I’m closer to 450hp
I think the hard launching (you had quite good grip especially in 4wd) overloaded the rods and weakened them. Enough of this doomed the motor.
It definitely weakened it. I did a ton of launches.
Very interesting indeed! Did you buy Snowflake as a used truck? If so obviously if "you" weren't the original owner of her, you wouldn't know how the engine was cared for or how the truck was used. Otherwise the OEM Ford fracture-split connecting rods are indeed the weak point of the 2.7 liter EcoBoost V6, likely 2nd the factory OEM cast pistons. I'm certain the factory 2.7 liter crankshaft is a forged piece.
It was used, and based on the carfax it appeared to be a daily highway driver on lien from a dealership. It had the top end rebuilt not too long after I had bought it. Yes the crank is definitely forged.
You're very possibly right though that that particular 2.7 liter EcoBoost V6 in Snowflake might have been already compromised if the top-end had already been gone through. I know you look obviously nothing but great care of it! I know 5 Star Tuning, quite a well known tuner for Ford EcoBoost motors has really pushed the 2.7 liter EcoBoost to quite high levels with no catastrophic failures like that.
@kriswinger9391 I don’t think the cylinder heads being replaced had anything to do with why the motor blew up many thousands of miles later.
5star has done their fair share of 2.7s though nothing to the level I was at. I have the record for the fastest gen 1 4 door 2.7 f150 that I know of. I had custom turbos and a fuel system that was not available to 5star and not even available to the public still to this day actually. I did so many launches with the truck too. My records are proven with datalog data and dragy numbers whereas all 5star has is dyno numbers and those are very subjective and unreliable.
Looks like it's all towards the intake valves. Too much cylinder pressure I'd say.
@208Concepts no doubt haha.
I have the best and fastest 2.7 2015 with 2255310.1 miles and still running strong bitting red eye hell kitty .
Me and my brother have the best answer you are looking for.
Yeah and what’s that
No, you haven't figured what your problem is. Your 2.7 failure is due to the exaggerated amount of power you decided to go with by maxing out the design. What you in reality found there is the outcome of a not well planned tuning and lack of experience.
Yes I have. I am not the tuner of the truck and i am learning just like anyone else does. Don’t need a smart comment on what I did or didn’t do. Thanks bud
