To say a 5.0 engine with an aftermarket Nitrous kit is more reliable than a tuned Ecoboost is a stretch.

Well... I guess that depends who tunes your ecoboost... If the tuner has a track record of blowing up Ecoboost, then yeah.. I agree.

A stretch possibly, but there are a lot of modded, boosted, and Nitrous'd (?) Coyote 5.0's around, yet strangely, there are a lot of 3.5 eco's on every F150 site that have failed catastrophically. Sure there is a lot of them around, but not a whole lot more than 5.0's The Coyote has proven to be very stout, and a 100shot with a progressive controller really ain't that big of a deal.

Our very large fleet at work runs both engines, and you'd have to poke holes in every other 5.0 oil pan to rival the issues that we have with the 3.5 eco

Either way, if you drive an ecoboost, you have to listen to an ecoboost, which makes it all not matter, especially staring at my tail lights

The eco's make power with 6 cylinders as opposed to 8 with the Coyote. If the eco makes 400hp/400ftlbs, that's 66.67hp and 66.67ftlbs per cylinder. If the Coyote makes 400hp/400ftlbs that's 50hp and 50ftlbs per cylinder. The eco cylinders see more hp, tq, and "stress" on average.

True! Bmep calcs tell the story!

I will never ever ever run nitrous on a vehicle I own. Seen too many failures from it. Do it right the first time and go supercharger or turbocharger.

Fair enough - I lived in the FI world, and failures happen in every form, the common denominator is tuning, and install quality.

Nitrous has lower cylinder pressure per hp, cooler charge, more knock resistance, and a terrible reputation. Too many squids running NOS I suppose. It's not for everyone, but I like the "stockness" the 99% of the time that a 14 sec truck is adequate lol.

Also, when it hits -30, I still have a truck, not a trailer queen!

That's the most generic argument I have ever seen. Like saying more people are killed by bee stings than sharks. If your telling me you've seen more Coyote's blown up that's one thing, but honda's or other vehicles is apples to oranges.

In 1500 and up applications your 100% right but we aren't talking about that. Of course, as it's been said, it all comes to tuning and user error. I can guarantee you there are people out there who have blown there N/A motor from taking the air filter out and going off roading....

My personal opinion is this, basically. It's still a V6 trying to move a huge truck, so the engine is almost on "kill" from the factory in order to make 470 ft-lbs. This is what my tuner friend says and why he has never liked the ecoboost. He has friends in Ford R&D and they will admit as much (according to him).

To be clear, there is nothing wrong with the eco and it's fine for the average person wanting a truck that does it's job (and the eco's are indeed very fun to drive stock!), but as soon as you start trying to make serious power there is just no contest. Sure you can tune an eco, but it will always be a V6.

thanks for the laugh

My bad. I didn't look back in the thread far enough. I thought I was safe making those comments in a 5.0 nitrous thread.

Not trying to ignite a debate. The point being made here is it's objectively safer/easier to make more power with a V8 with a PA than with a turbo V6. I'm not sure how that is funny.
