Phasing out the V6

[trublie]

In addition to winter conditions, the handling and sure-footed cornering are great for cruising on twisty country roads. This certainly won't be for everyone. Have you driven the Taurus SHO?

Good point.

Have you driven the Taurus SHO?

I have not, but back in the 80s/90s I worked for Chrysler and spent time with the Talon TSi AWD (and the Viper ) at the proving grounds and on public roads. It was great. I'm sure what I experienced was nothing like a modern AWD system, so maybe I'll test drive an SHO when I look at Mustangs.

There are strong arguments in favor of the EB, and I was (and to some extent still am) on the fence between the EB and V6, but the following post in the EB sub-forum (http://www.mustang6g.com/forums/showthread.php/oil-catch-can-2425.html) is very interesting to me. In a nutshell (pun intended), the link in the post discusses the carbon build-up problem that tends to happen in DI engines, and ways to get rid of it.

If you want to auto-cross or mod, I can see the appeal of the EB. But for those looking for a low maintenance, daily driver (the sort of car I'm looking for), I think the V6 still has a lot of merit.

I have no experience with DI engines, so I can't add anything to this.

Mishimoto looking forward, please dont make it expensive

If you have to BG or media blast the valves every so often then go for it. If it works and its a great benefit to the motor's longevity, who wouldnt jump at the chance to get their hands dirty under the hood

Ford will probably make a recommended cleaning service and re-engineer future models. Maybe both port and DI (Lexus does this), or put additional oil catches that just dump the fluid back to the pan somehow?

66coupe,
That was an excellent post about direct injection. Carbonising (carbonizing), I had no clue. The link was extremely revealing too. I believe it was mentioned that recirculating gases and oil were the source of these deposits. I installed billet oil recovery traps from JLT on my '07 GT500 between the valve covers and air intake/supercharger. I could not believe the amount of oil and sludge I collect after just 1,000 miles. I wonder if this might help slow down the carbonising process. I believe it was mentioned, that routing the material to the oil pan or filter might also be a solution.
Direct injection is too valuable a technology to abandon, I hope the mechanical engineers at Ford will be able to find a permanent solution.

It's not just boosted engines or DI, this sludge builds up in all engines to some degree. VW diesels are the worst I've seen. Que race gas or low lead aviation fuel, race oil with ZDDP, and removal of cats. Then you have a clean engine. Never use leaded fuel or oil with ZDDP with catalytic converters unless you want to clog the cats with all that shit that blows out of the engine. Leaded fuel also shortens the life of spark plugs (eats away the insulator) and possibly sensors exposed to combustion or exhaust gases.
