The new ford RAPTOR

Crazy that they will change to the 3.5 liter ecoboost over the current 6.2. I wonder how reliable that motor will be with almost 500hp.
 
i'm afraid to ask what those bad boys will start at. i'm also not so sure what the reliability long term is going to be with the eco boost.

Actually direct injection pushes 2000-3000 psi, so gunk on the intake valve won't be a problem

This was perhaps a poor choice of words on my part and may have gotten this discussion headed down the wrong track. Some say direct port injection, that's what we've had for years. The newer use of the term direct injection and that to which I was referring goes straight into the combustion chamber. Direct injection never sees the intake side of the valve, hence the problem. Because it is injected directly into the combustion chamber, it never has a chance to "wash" over the intake valve. Add a supercharger or a turbo combined with normal blow by and you bake the blow by to the stem side of the intake valve. This is a problem industry wide with numerous fixes dependant on manufacturer. I believe BMW actually has the intake pulled and use walnut shells to blast clean the intake side of the valve.
