Finally an effort from Porsche to get back to the top classes of racing with a factory effort for privately run race teams.

The interesting thing to me is the info about the engine.... "The Porsche prototype will be powered by a new 3.4-liter, 90 degree V8 engine. Able to produce 480 hp at 10,100 rpm.....". Maybe overall a bit but I think still worth mentioning to any 928er due to the new V-8 powerplant.
Imagine if you could get that into a Shark!

 

In a 928 a stroker is probably as good of an alternative. More power at lower rpm's.

 

Yeah, I'd rather have the low rpm torque, but its interesting to wonder what if......

 

You know, I don't really like the flow of Sports Porsche nowdays. Carrera GT-V10, this car above-V8.
V8 is grteat in road cars like ours but in the sport, they are not well balanced except for the V12.
What I really respected was when Porsche put in 4.5 flat 12 in the 917(I think) around 1968 and it generated 1200hp. No computers, just pure mechanical engineering power.

BUt going back to our engines, I think new koenig(did I spell it right) will use 4.7V(don't remember the number) to generate 700hp. That is pleasant to hear...

Sweet looking racecar....hopefully it will generate some wins for Porsche! It is safe to say a 3.4L V8 that makes its power at 10K+ rpm would not work well in a 928....a cayenne TT engine (500hp stock) would be a better choice (if it would fit)

Oh my god... it's on Michelins.

 

does anyone have a front shot of this car? I'm wondering about those double roll bar arches

 

It is a "two seat" , the rules do not allow single seat cars in that class.

 

Yeah I saw the Michelins & thought they might want to rethink that. I also noticed the double roll bars & wondered about the two seat configuration. That explains it!

 

Here is an overhead view from the article showing it better. Interesting it only looks to have one actual seat. As though the other slot is available but not in use.

 

Awesome. Simply awesome!

 

HOT DANNNNNGGGG!!! Thanks Mel ... now I can finally get back into racing. It has been a hell of a long time -- remember Jody Scheckter and Jacky Ickxx? At Kyalami? Well this is gonna be so fun. PORSCHE racing ... nice Now we can show Audi the

 

What the hell class is this? 3.4 liters? And a V8; Is this a '98 Taurus SHO or something?

[A friend of mine had one of those; it wasn't fast from a Porsche standpoint, but it went well anyway and that engine was a jewel- NO vibration at all, and it sounded great. Good idea, but it must have been expensive to produce!]


V8 vs V10 vs V12- When you get into this territory, the engines are expensive to produce for a car company like Porsche no matter what. V8's are easiest on fuel, and have the best breathing-intake possibilities. V12's have the smallest pistons = highest piston speeds and the most power from a certain weight. V10's suck period...but in F1 they are used because they fit the rules in effect today the best. Why did Porsche put a V10 in the Carrera GT? Because that V10 is a racing engine who's investment cost they didn't want to squander. Trust me- V10's sound like crap and vibrate too.

V8's rule!

N!

PS: Point of trivia for you non-928 people. The "spider" intake you see in my picture is actualy composed of 5 part numbers. The center plenum has a part number, of course, but the legs of the spiders are only in four numbers. The tubes on the left and right are the same, but re-arranged. look at the picture carefully and you can see how Porsche re-arranged the tubes from one side to the other.

To add dirt to the whole subject....in 928 land there are actually 8 intake tube numbers for the 2 valve cars; What you are looking at in that picture are the wide, highly desireable ROW tubes. The American cars had intake tubes far narrower. These, along with larger valves, wild cams, LH-Jetronic injection, and MUCH higher compression allowed this V8 in my car to produce nearly 100 hp more than a similar appearing and same-size V8 in an '84 US car!

 

Normy - IIRC, The V8 (V6 in the earlier models) in the SHO was a YAMAHA engine!!

 

Yes Mark I know that, it's similar to the SHO V6 but a new design. The new Volvo SUV has a 60 degree V8 that is actually the old Yamaha Taurus V8 bored and stroked out to 4.0 liters and 280 hp.

N!
