LokiWolf He did say it had 1000 injectors and was running e85, and the literal name of the tune was "Agressive Tune" hehe
Yeah, cause that helps.

That engine with 1000cc injectors on E85 could theoretically make well over 700HP at the flywheel. To reliably produce that level of power, you have got to make sure the fuel system (not just the injectors) can handle the flow and address the engine internals. The crank looks to be a good piece, but the rods and pistons would need to be upgraded.

Forged steel crankshaft - Good
Forged powdered metal connecting rods - Not Good
Cast aluminum pistons - Not Good
Yeah, 1000cc is about middle of the road. Just because he has 1000cc installed, doesn't mean he is pushing anywhere near 700HP. I have heard NO mention of upgraded Turbos, and those would be needed for that power point.

Again, this failure is FAR LESS likely about the power level he was pushing, and FAR MORE likely about the quality of the tune. Most likely the E85, had low E Content, and the Knock Sensors were disabled. Instead of it adjusting timing due to knocking it grenaded. Dependable power is WAY more dependent on good tuning on these motors and far less on the hard parts.

I REALLY hate this guy. Sensationalist crap. This video is making the rounds. I stopped watching once he started doing the teardown. I know at the beginning, he does not mention the tuner. Does he ever?

So much more to the this.

1) Who is the Tuner? There are MANY documented crap ones out there, that disable many of the Ford safeguards like the Knock Sensors.

2) Was he towing on a performance tune?

3) Was he testing his E85?

4) Was he regularly doing more maintenance?

Saying because one motor went boom on an "Aggressive" tune, tells you nothing. Very detailed on everything except what matters.

The 3.5 can handle a substantial amount of power over stock and maintain longevity if done properly by a good tuner, if they leave safeguards in place. Period. Our 2020 is 40K in with tune, and zero issues. Runs E85 for 5 Months out of the year, and a hot 93 tune the rest. If I tow with it, I tune to a tow tune.

Most likely this was a combination of owner and tuner fault. I haven't heard who it was tuned by, but I am sure it will come out at some point.
That's all I ever hear about is how bad they tune them in the safeguards they take out of them some guys say they can tune but in reality they don't have a clue or understand the system
