Ruf builds a V8
 

(Old news for those lucky Pelicans who get their copies of Excellence sooner than I do):)

4.5 liter, 32 valve, 4 cam V8 rated at 550hp@8500rpm(redline)(!)/367 lb.ft of torque@5400rpm. (Nothing in the article about the vee angle)

Here's the kicker, it weighs 485 lbs, compared to the current GT3 engine that weighs 584. Plus it will sit two inches lower in the rear of the 911 than the flat six.

Interesting fun fact: direct drive for the water pump, generator, and AC compressor - no accessory belts needed.

Production begins in late 2011.

Man, that will be killer.... wonder what the cost$$$ will be? I'm sure Snipe will be here in 3 2 1

will the timing belt replacement be as much fun as the earlier editions????????????????

I like the idea. Sensible engineering and lighter.

One thing of note is that Porsche is using a strengthened version of the Carrera engine for their new Turbo.

That means they are dropping the proven 964/993 cased version!

I wonder if RUF were inspired by the many American V8 conversions. :D

mmmmm yummy! wonder how that would drop into a regular old pick 'em up truck? LOL!

by the looks of that motor, I'd say.. no.

Seriously, it's about damn time they put a real engine in the 911. :D

PS: That looks very close to a conventional 90 degree V-8

I just hope production 911's get a flat or V8. I think a flat8 would work just as well. I don't see a reason that it has to be a V for space or weight reasons. What about a PUSHROD flat 8?

Why would anyone build a flat V-8? They're totally obsolete.

So are pushrod motors for that matter. ;)

I love the engine. Kudos to RUF!


But please keep it the hell away from the 911.

There's a difference between a flat-v8 and a boxer flat-8. It's in the crank.

The Ferrari Testarossa is one rare example of a flat engine that is really a 180 degree V angle engine- it's not a boxer in the way flat 6's and flat 8's from Porsche are.

This is why they need to build a flat 8:

And it needs to go in a Cayman.

Seriously, that engine is as much needed in a 911 than a flat 6 would be in your 928, and equally welcome IMO... ;)

+1! on the "keep the hell away" part.
And as much kudos to Ruf as all the other Porschevs out there.
I'm not a purist all of the time, but a V8 in a 911 is automotive blasphemy, again, IMO

When this day comes, please let the gods of design use their powers and transform the looks of the 911 as well, in a Pinto, or Chrysler Le Baron, or something equally stunning....
Next time, use green font, so others know you're kidding....

Flat head V8? WTF?

I know, I know...heritage.

Well we need to beat the ZR1. 632 supercharged power out of a 6.2 liter.

Eventually you need displacement. Porsche can gizmo a six cylinder all they want but eventually you need to add displacement and possibly cylinders.

There is nothing "anti-heritage" in making a flat6 a flat 8. Plus imagine the sound...

It befuddles me that anyone alive would not want that V-8 in their car.

No wonder 928s were never accepted by the 911 KooLAiD drinkers...

Not only is it bigger and more powerful than the obsolete flat six, it's significantly lighter as well!

Once they went to water cooling, a V-8 was inevitable...right, Snipe? :D

If they had any sense they'd be SCREAMING for this motor in production 911s! WHAT IS THIS FASCINATION WITH AN ANCIENT VOLKSWAGEN ENGINE???

Craziness.

Here is a Lycoming flat 8, 11.2L (720 c.i.) 400shp non turbo introduced in 1961. Could mod one of these easy!!

Put it in a 911? What are you crazy? I want to put it in a 550 SPYDER Replica!!!!

I'll buy Depends by the case. The car will cause massive bowel evacuation every time I pin the throttle and I'll keep coming back for MORE! :D

So what the difference between a flat 8 and a 180 degree V8?

Here is something few people realize, simply because they accept the status quo: Humans are not the slightest bit objective or logical or rational. We are truly subjective creatures and our decisions, both individual and collective, are more "art" than "science." Porche has perfected a single engine/car design over seventy years of development. Does it make sense? Probably not. Does the internal combustion piston engine make sense? Probably not. We'd all be better off if we had moved to a Wankel engine or better yet, a small turbine decades ago. But we haven't. I think it probably has to do with our appreciation of the reciprocal action of a piston going up and down in a cylinder. It's Freudian.

I do not know 911s very well (944 owner) but does anyone know if these will fit into 996s? If so, they could have a lot of sales from people with RMS and intermediate shaft issues.

I've heard this before and I don't understand it. If the cylinders are horizontally opposed, where does the V angle come in?

They should fit as the 996 engine bay is very similar to the 997's.
The biggest problem would be the cost.

The Ruf engine alone is probably worth more than most 996's!

A better option for the 996 would be an LS1 V8 like in so many early 911 conversions.

I haven't seen any converted yet but it's only a matter of time IMHO.

A true boxer flat engine has a crank that has one crank pin per connecting rod. 180 degree V engines, as they are called, share a crank pin for cylinders like any other V engine (SBC, etc). This is how the Testarossa was designed. So even though the Testarossa motor is often said to be a boxer 12, it isn't.

But people who want spoked wheels (or wooden spoked wheels) on their 911 will NEVER want a V-8...

Not if you take out a lot of wt. And that appears to be where Porsche is headed.

Light weight solves a host of performance, emissions, and env'l problems - all at once.

Wait & See.

I'm hoping Porsche goes the Lotus route as well.

Extruded & bonded aluminum chassis structures are where it's at.

You say that like you are a chasis engineer or something.;)

I think I need to phrase my position as a question so we get a yes or no instead of straying:

Would anyone be opposed to Porsche building a 911 with a 6.0 liter flat-8 engine (Roughly 450lbs, or same as current 911 engines)?

I would not be opposed to that, just don't call it a 911.
