From what I have read up, and read between the lines, Ford focused their FPC on creating the most broad power curve, highest power-density and maintaining a Mustang-type sound. If you start reading about the Voodoo's UDUD layout vs. the typical UDDU layout of Ferrari, Lotus, McLaren, and Porsche, the UDUD layout apparently has more vibration concerns related to it, but allows more flexibility in attaining better intake/exhaust manifold layouts, which the Mustang was said to have had as a restriction. I have a strong suspicion that the C8.R has a UDDU layout. Quote:

But, if that were the case, they ALL would be consuming a good amount of oil (some more than others, of course). But, most folks over there swear their engines use no oil at all. So, I can't see the oil consumption issue as anything other than a problem, not a design feature... |

I could understand a packaging issue, but I have no knowledge of that. I can not understand the argument that a CPC has uneven pulses, and therefore can't be used in a TT setup. There are plenty of CPC TT setups out there, so it is possible...

Yeah I would believe the packaging issue.

Perhaps one day we will find the root cause, but for now I can only guess. |

I'd be curious to see the rebuild specs between the 5.0L Coyote/Road Runner and the 5.2L Voodoo for piston ring gap. I know ring materials are a lot better today than 15 years ago, but when considering the factors I stated, it's believeable to me for a larger initial gap. One the other hand, it is evident that Ford had some quality issues with their plasma-bore sprays with the early Gen3 Coyote, so I'd think that it's very possible there may be that. The blue smoke might be quelled by the catalytic converters? There is, also, a long series of piping going out to the back of the car. If, say, the engine is only burning oil at low-RPM, let's say under 3.5k, that would be a small window with a long, semi-torturous path. I mean, have GT350 owners really observed their exhaust close enough to say, "Nope, there is definitely NO visible blue smoke, what-so-ever, coming from my tail pipe"? |

My guess is the oil is burning, not leaking, but not sure of the root cause. Some indications were that the cylinders were not perfectly round, and there is one case where an owner already voided his warrenty (by going TT), and his engine had a large scratch on the cylinder wall. Now, he swears it wasn't the TT build, as it didn't have that many miles on it, but that is only one case, and it was modified, so... |
