Ford rumored there would possibly be a "3rd" engine at the Raptor's SEMA debut. I thought they were putting the ecoboost in the Raptor just to prove the engines durability, nothing more.
Twin turbo, 4v per cylinder and direct injection. The 6.2 is a 2 valve, iron block pushrod simpleton. Everybody was suprised at Ford for making such a throwback engine.
Sometimes the "throwback" simple engines are the best. As much as I hate to say it the LS motors from GM are a good example. Old school simple, but yet they make good hp easier, cheap-er, light weight, compact, and efficient. Hard to beat.
The ecoboost is an impressive engine. But start to really push it and all those cool features are going to bite you in the ass. Eventually, sooner than later, the tuner guys will push it till it runs out of fuel. Imagine how expensive an upgraded high pressure pump and injectors will be?? Imagine having to spend 5,000 dollars on fuel system stuff alone to make it support 650+ hp. Then you have two turbos to buy on top of that when it comes upgrade time. You haven't even touched the rotating assembly, heads, intake, exhaust, cams yet. Modding the ecoboost to mild-extreme levels will be an expensive mans sport.
I'll take the 6.2. Don't need 4 valves when you have a 4" plus bore. You can get away with two larger valves and not have shrouding issues. As it sits the heads flow very well. Better than the ecoboost i'd bet. Sure a 4 valve BOSS head would out flow a 2 valve. But does it really need 4 valves? No. Does it need an expensive direct injection system or twin turbos to make its hp? Nope. Will I be able to find a builder boss motor in the junk yard in a few years out of a wrecked work truck for cheap? Yep. Can we say the same for the ecoboost? Probably not.
Besides, what kinda hippie tree huggin, granola eatin, hemp smoking, ****** name is EcoBoost? At least name it somthin ****** mean if your going to drop it into the Raptor.
