Dude are you trying to say a GT3 street engine will run better and stronger than a Nextel Cup motor??

 

Oh boy.

So, tell me... 5.0L BMW V10 vs. 7.0L Chevrolet V8:

Which gets better fuel economy (no cheating with M5 motor in P400)?
Which motor is more compact?
Which motor produces more torque?
Which motor weighs less?
Which motor responds better to MODZ?
Which motor costs less, and by how much?
Which motor is simpler and thus more durable/easier to maintain?

EDIT: standard disclaimer - I have never owned a Chevrolet in my life, but I have owned several Porsches and my current daily driver has a 3.6L twin turbo flat six. Don't even think about calling me a Z06 or Chevy guy. Gracias.

 

I think Chris meant to say the LS7 platform is as good or better than anything the euros have to offer. I'm a little sick and tired of all the Z06 bashing around here too, as an American I'm proud to see the Z06 besting the europeans at their own game.The Zo6 is a fantastic performer on and off the track. Hats off to Chevy, they bench marked the TT and nearly blew it out of the water.
I'm still getting a TT because it's the better car for me, if I had the garage space I would get a Z06 and a GT3 to complete the trifecta.

 

How about try comparing apples to apples, nextel cup RACECAR motor to GT3 street motor, hmm that's kind of silly no How about a race prepped lemans gt3 cupcar, gt2 car, you name it!

 

I am sure no more than 2% of the people who buy 997TT's care whether the Z06 is faster around the track.

 

Yeah probably you are right

 

One of the biggest knocks on the m3, m5 and GT3 small displacement, high reviving, high horsepower engines is that there is no torque. Sure the power is great at the 7-8K rpm range, but I think most people prefer the bigger displacement or force induction engines for street driving. Plus they respond much better to mods.

The chevy 7.0 liter engine weighs 458 pounds and the bmw 5.0 liter comes in at 529 pounds. Ever try squeezing an extra 50 horsepower from an bmw engine? Not an easy task.

 

I'm sure that is true, just at the murci owners don't care how the 997TT's stack up in acceleration. Most of these cars probably never see the track anyways.

 

I am curious to see the fuel economy comparos WOT and not in the standarized tests companies put their cars to. Also I would like to see their emissions.

The maximum output a thermodynamic engine can achieve is about 0.4. (work produced/energy consumed). The average observed efficiency for otto engines is 32%. I would really like to see someone put both on a bench dyno, calculate the work they produce in an hour of variable RPM's and give us his results.

Still I think it is pretty easy to see 5mpg in the Corvette although it's ligher and has less transmission loss than the 997TT.

Though, I think it is stupid to say which is the most fuel efficient when we are talking about cars that cost 70k or more in the first place.

THey both do a job equally well. In a different way. It's like trying to get in a glass house. You can either cut the glass with a diamond or just throw a stone to it...

 

No. look at what martin said, your comparing a stock gt3 to a race vette. compare a stock gt3 to a stock z06 and the gt3 takes it.
compare a race gt3, gt2, gt1, RS spyder to a race z06 and there is hands down goes to Porsche again. Porsche has been doing this for such a long time and has the MOST race victories i believe in history, theres a reason for that.

 

You know what, sucks for the vette when the nissan GT-R comes out because that is going to be hands down the BEST in all the catagories you just mentioned above when comparing the two. 5K in mods to that car, prob less than that too and that GT-R will be just as fast if not faster than the CGT, and enzo and the likes.

 

Isn't the 996TT with 6-7k as fast as the CGT in the first place (straight line only). WHo cares about value? It's like having two women to chose from and picking the one that cooks better...

 

I'm all for more fast cars.

But dude... the specs of the GT-R haven't even been announced yet. Quit talking out of your ***.

 

I dont care about value whatsoever, i just think the gt-r is going to be a great car. and prob about that maybe 10K gets you CGT speed in the turbo.
