car is hot **** right there! had one driving next to me the other day...mother ****er pulled!!

 

Please inform me as to how the STS-V will be nowhere near what the M5 is? What does the M5 have that the V does not? Personally I think both are overpriced.

 

Not really. Actually, the torque is quite high for its displacement. LS7 : 7 liters, 475 lb-ft of torque. 67.86 lb-ft of torque per liter of displacement. M5 engine : 5 liters, 383 lb-ft of torque. 76.6 lb-ft of torque per liter of displacement. It is actually creating alot of torque for its size, and is probably pretty high in the volumetric efficiency deparment. The reason it makes 500hp with only 383 lb-ft of torque is because it revs its *** off.

 

The M5 has 38 more hp while weighing about 150 lbs less than the STS-V, so the BMW has at least that going for it.

 

Size of the motor means nothing unless you are talking John Force #'s . One of the biggest torque monsters of its day was the 1987 Buick Grand National that had a 3.8L V6. The 4.1L Buick Motorsports stage 2 motor I had in it had 1100+ Ft lbs. Look at it this way, it has less torque than the C5 Z06. That is also another thing going against it vs. the STSV even though the M5 has the extra HP.

 

What are you talking about?

In a direct drag race, my money is on the M5, given equal drivers.

 

I'll bet its alot closer than you think. Torque is what gets you down the track. What do you think it would do to the C6 Z06's times if you knocked it down to 383ft lbs. Do you not think it would have an effect on its times? Thats what I'm talking about.

 

Torque and horsepower are not indepenent of one another. You couldn't knock the z06s torque down to 383 lb-ft, and still make 505 hp, without radically effecting how it makes power. Torque does get you down the track, in a sense, but HP shows which engine is doing more work. The car with the less weight, and the higher HP, is going to win, as long as the powerband is decent and the driver is not an idiot. I don't think you understand what actually gets you down the track.

The M5 is going to win, unless there is some electronic intervention the PCM uses that I am not aware of. As I also stated earlier, for its size, the M5 engine makes alot of torque, and can make 507 hp with 5 liters because it does make alot of torque for its size, and carries that torque much higher into the rev range.

 

It's just a matter of time now, til Bob C the 'professor of torque' logs in...

 

Let me see if I can make myself a little more clear. Put the M5 motor in the C6 Z06 and tell me it will run the same numbers.

 

At the last GM ASIM, one of the CTSv driving instructors said he did some work for BMW. One of us asked him if he's driven the new M5. He said yes. We asked him what he thought.

He said, and I quote..............


'OH.................MY..................GOD!'

 

Depends on the weight of the motor, but it might run better. You could certainly gear the car down lower, given you have another 1250 rpm to work with.

 

I would take a new M5 over anything Cadillac has to offer right now. BMW did their homework on that car. Can't wait for the M6 (not that I will be buying one )

 

Compare the strait line performance of the Z06 with the Ferrari F430.

They both weigh approximately the same (3200lbs), and the Ferrari makes just shy of 500hp and 343lb-ft of torque from its 4.3 liter V8. It does however rev to 8500rpms and will run a mid 11 second time slip trapping in the 120s just like the Vette will. Granted, the Vette is a few ticks faster, it goes to show that gearing and the ability to rev can make up for lack of shear grunt.

I'm sure the M5 has no problems whatsoever accelerating.

 

Thank you.
