Actually, a V-8 has a fairly low center-of-gravity. The heavy stuff (crank, some other shafts (lay shaft, int. shaft), and oil pump) are still down low. The tops of the cylinders, cams (if OHC) and heads are higher than in a flat design; however a V design is much stronger structurally than a flat design, so there may be some gains there.

The cams and heads and all of the intake hardware are still going to be much higher than on a boxer. This is less of an issue when the weight is concentrated within the wheelbase, but I've got to wonder what happens when it's hanging out behind. Ruf has always been more about v-max missiles, where transitional response is less of an issue. I'd love to see this motor in a 987.

I think this is cool.... I would prefer a "flat 8" though.

The fact that it will have a "FLAT CRANK" V8 engine, will make it VERY special motor and with a 8500rpm redline it should sound incredible. I cant wait to hear this thing.

haha that is too funny....what is up with Uwe? There are too many rumors doing the rounds to make any clear judgements on this one. First it was kidnapping, then it was his wife wiring 1 mill before he dissapeared and then he opened a shell company with his mother....who knows.

ruf has always made some sweet rides in the past so he just might know something we are missing here regarding the switch to V-8's(would of loved a flat 8 though)

I like it.

I'd like it better if it were mid-engined and reminded me of an updated 904.

I assume that Ruf considered and rejected a flat-eight due to packaging limitations.

yes, width is another adv. of a V-type

a flat crank will sound like an Fcar...

I doubt the induction system is much higher than on a flat engine - like I said the heads will be, but that is not much wt. Think about how much your heads weighed last time you had them off...

The benefit is that it is built to make power at very high rpm's. Ferrari, indy cars and f1 cars, have all used the "flat crank" in there V8's.

I would be moooore than happy to have this engine in the back of my porsche and I expect the reviews to even put the gt3 to shame.

Another nice thing about this Ruf V-8 is that the owner probably won't have to worry about having his a$$ handed to him by a lowly Corvette C6 Z06.

Actually, you're completely wrong. There is no Cayenne connection.

I dunno, looks like a pretty lightweight and compact engine. I hear what everyone is saying about the heresy of a V8 in a 911, but I'm inclined to give Ruf some slack. I think most of the projects he has been involved with for the last 20 years have had more Professor Porsche DNA than what the factory was doing. On some level the factory watches Alois the way Mercedes used to keep tabs on AMG. The flat aircooled engines had a great run, but given what is required by governments to get a car on the road these days I doubt we'll ever see another.

Awesome! it still doesn't put out the torque an LS1 or an LS6 does though, but it revs higher.

They (flat aircooled) have been gone for over 10 years (12, I think). The 996 was the beginning of the watercooled engine.

We will not see another, I think you're correct.

I wonder if the reliability problems with the water cooled flat 6 engine motivated the development of this engine.

I've often read that these problems only affect a small percentage of the 996 engine but it seems to me a lot of people are earning a living by fixing these issues. What is the real percentage affected? I guess we'll never really know. I still find it hard to believe Porsche built such an engine.

The latest Turbo uses a modified 997 Carrara engine as its base. We'll see were that goes.

Maybe Ruf doesn't want to find out.
