I honestly dont know too much about what the power gap is on a stalled A4 car vs. a M6 for them to run about the same, RWHP wise. But i was just wondering, say you had a 380RWHP Stalled A4 Vs. 400RWHP M6, who would win, and by how much?

 

Depends on driver. If the M6 had a good driver and could shift, the M6 could take it, it would be hard though. But it would be fairly close either way I would think.

 

the stalled auto with traction.

 

from a roll the m6 should win. from a dig, the auto should win.

 

What kind of race?

 

 

Any, I'm just curious

 

Can't say "any" because the outcome would be totally different.

From a dig @ the track, the A4 has a slight edge due to launch however if the M6 has a good drivetrain & driver it's anybody's game.

From a 55 mph roll, a 400 rw M6 would eat alive a 380 rw A4. Back in 99-00 I was outrunning cam only A4's in the 360-380 rwhp range with a stock internal 351 rwhp M6 car.

 

Good info, thanks! But why is the A4 not so good from a roll?

 

I believe its mostly in the gearing and how much power its stealing vs the m6

 

Thats pretty much it.

Ever ride in a bone stock A4 car? Go WOT into 3rd gear and feel how far the car falls on it's face from the 3rd gear ratio. Same applies to a 380 car, just doesn't feel as bad because the car is making more power. An M6 car keeps pulling all the way through 5th gear, especially w/ 400 rw.

MPH is everything in a roll race.

 

The auto car would win from a dig, M6 from a roll by a lot.

 

Thats because A4's suck!

Ever tried to launch an M6? If we rev to high, the tires will spin, dont rev enough, and it falls on its face. A4's don't bog, due to the stall converter. This comes at a parasitic cost. The M6's don't have this loss when roll racing, with a strong enough clutch, its almost like a direct-drive system.

 

ive stayed even or outrun several 400 rwhp M6 cars from a roll. my car only dynoed close to 380 (386 i think).

 

The M6 cars werent driven properly, or you went from a bad speed for them.

 

well a stalled auto that has 380 at the wheels has a LOT more at the fly wheel. stalled autos dont dyno well at all.

 

 

your trapping 119.7, thats more than most cam-only cars. In fact, 119.7 is right around where I'm running at, is your car super light or something?

 

I believe you, because you are trapping 119 mph. But, your average cam&bolt-ons LS1 wont be trapping 119, and probably won't be keeping up with too many 400rwhp M6's from a roll (assumming the M6 driver can drive, M6 is ALL about the driver). With that said, your car is haulin' some *** for cam & boltons!

 

my buddy with a 02 ws6, Tr230 cam, ls6 intake, 12 bolt w 4:30s, asp pulley, 1 cutout, M6, elec. w/p, shortbelt mod, LT headers and his own ls1 edit tuning went 11.6@120. the DA was -500 which is great and he did have skinnies up front and 15" w/ slicks in the rear. other than that it was full weight. nothing removed.
