What to get: 2006 Z06 or 2006 911 S?

[CAP1]

Cap, these cars all won at the time Porsche was just cutting it's teeth in racing. The GT40 was produced to beat Ferrari's that were domainante at the time and all because Enzo backed out of selling the company to Ford. After 1969 there was no American winner at Le Mans to date. Ford and Chevey like Ferrari and Porsche chose to put their resources into different areas of racing. As far as endurance racing is concerned nothing US built ever was able to compete, not at Le Mans, Sebring nor 24 Hours at Nürburgring where Porsche won the last 4 years. I believe there are US built cars racing there as well. Now Europe was and imo still is the apex of auto racing not NASCAR, IRL nor American Le Mans series. The American Le Mans series doesn't have the worlds attention as do the big races in Europe so trying to compair these races to those is ridiculous.The constant reference to the Corvette beating the pants off of Porsche and Ferrari in racing is a rather small minded comment. I suppose that if GM of Ford wanted to compete in F1 they would domainate there as well.
Corvette is domainate in a very limited type racing that now many people that they are the kings of the racing world not to mention the streets of the world.

how can you say nothing us built never won? the gt40(even if it was designed by lola) was built by ford. powered by ford. and it won 4 years.

i know why the gt40 was built. and it proves my point. ford set out to beat the best.....and they did it with style.
 it would stand to reason, that should either ford ot gm decide to do so again, that they will, with relative ease.

nascar sucks......it's so frakkin neutered, it's frightening. irl....eehh.....never been much for open wheel. trans-am racing if enjoyable to watch. and coincidentally, the mustangs kicked everyone's bellybutton in their class last year...including the AWD audis  in the rain.


also, wasn't there an oldsmobile engine that was dominate for a time in f1? or was that in the indy racing legues?

[Die Hard]

Reaper, I'll want to see GM balance a checkbook before taking on the euros on their own turf. Ford did beat the euros back in the 60s, but only by hiring the euros to do it for them. The GT40 is a Ford car, but not an American car. Most of the drivers were euros too.

If you want to prove American automotive superiority over Europe, the GT40 is not a good example. Just sayin.

[CAP1]

True.  Probably should have used the word inferior instead.

old technology isn't inferior.

otherwise there wouldn't still be pushrod engines. 

[Die Hard]

Well, push-rod valves are outdated and inferior to more modern valve technologies... However that doesn't make them useless.

obviously not.......the z06(i think) uses a pushrod engine to make its 500 or 600 usable horsepower.

i'm not sure about the zr1

It's Official, you know very little about racing, that quote proves it.

ZR1 uses a 6.2L LS series engine, with pushrods, just like the 7.0L Z06 engine.  Same engine family, different displacement.

They've been saying the pushrod engines are obsolete(oudated and inferior mean the same thing as obsolete), but we still see them, delivering comparable or sometimes superior performance as the so called new stuff.

[Bronk]

More compact yet = power. How is that inferior?

[Die Hard]

obviously not.......the z06(i think) uses a pushrod engine to make its 500 or 600 usable horsepower.

i'm not sure about the zr1

Sure, but they have large displacements. The japs and euros pull that kind of power out of a 2-liter. The ZR1's engine is a 6.3 liter.

....and the Japanese need turbochargers to hit those "power" numbers.

[Die Hard]

Of course.

[Bronk]

Of course.

Wanna slap a 5lb boost system on that Z06 and see if the numbers stay close?
Can be had for approx $5k.

Where is your turbo 2ltr now hmm?

[Die Hard]

Well, lets take the earlier example of the Porsche 917 race car. A 4.5 liter flat-12 with turbo. 1580 hp almost 40 years ago. What does the Corvette C6.R produce today with its bigger engine?

[Skuzzy]

Yes, but Die Hard, in the aftermarket, those stock Corvette engines can be pushed to 1000 HP and still be very streetable.  You can buy street crate engines that push 900HP. There are those who would argue that much horsepower is useless, but then they are not familiar with tracking thier car.

As an example, this weekend at the 2.5 mile track at Texas Motor Speedway, it is open day for racing.  $150 will buy a full day of it.  I'll see Cobras (kits), Ford GT's (actually, there is only two that race regularly), Corvettes, Porsches, Lotus, BMW, and everything inbetween.  It is just a safe and competitive environment for those who like to race.

That is where you can use that power.  The current lead car is a Cobra with a 427 Ford small block.  At the rear wheels, he is tipping over 600 HP.  He drives it to the tracks.  I have ridden in that car, and it will suck the blood right out of your eyes when he is in a hurry.

Although Texas Motor Speedway is a challenge due to its long straight.  It will be a fun weekend.

Here's a 1,000 hp Nissan Skyline. That has a 2.5 liter I believe.
