I had mine on it for a few laps in 2011 during a trackday, only because we blew the head gasket on the track car though. Not a lot of fun....1 or 2 laps is fun for giggles but I started getting...

Of course that's the best way to compare cars, to put them on the same dyno on the same day. But it's not really connected to core of the "drivetrain loss" discussion. As I pointed out earlier, a...

I take the 546 number with a grain of salt, it's a guesstimate done on a load dyno with coastdown losses. But the math works out pretty well, it's probably not off more than 10bhp which in the...

Of course there is a true loss figure on every car. But the suggestion was that one could find out this number and then apply it to other cars' results - from a chassis dyno so usually measured at...

I said there is no "true" driveline loss in the way you are suggesting that there is a magic percentage number that you can apply to every RS6 from then on. Of course there is loss, but the "I made...

There is no true driveline loss. It varies enormously depending on rpm (so if you make peak power earlier or later that will vary the loss considerably) and tire speed (gear).

That's why loss...

Stay away from EBC. Any pad they make is mediocre at best, not something you should put on an RS.

For proper pads go with something like Pagid RS-14/RS-19 or Carbotech. Be prepared to pay a lot...

Ditto. I'll bet 2 nickels.

Mine never moves doesn't matter if it's -25 or +30C outside standing still or moving. Once had the temp sensor go bad (when I picked up the car from a timing belt/water...

Yeah you'll have to purchase the OBD flash hardware. Not too expensive, and if you ever plan to change the tune it's the way to go. Pays for itself in that case.

Knowing my luck (and this car) it's going to be expensive!

Thanks!

No idea on the joints, may never have been replaced (car's at 77k now)
I don't have any unusual noise or vibration when turning (aside from full lock but it's always had that a little...

Since my gearbox was rebuilt last year, the car has a strange vibration when going from a stop or slow speed in 1st or 2nd gear. It only lasts for a very short time, half a second in 1st and maybe a...

With full cats and stock ICs that's wishful thinking on their part, well, more like standard tuning company practice really. With nothing but a remap you'll be lucky to see 500, that's pushing the...

I'd feel better getting them done, however it's not entirely impossible to replace the EGT's with everything in place. Merely difficult. Either way though the cheapest time to replace them is when...

When the TCU stops locking the clutch after detecting slip, it will give you a code that translates to TC clutch stuck OFF.

You wouldn't notice the TC clutch malfunction so much from a stop. If...

I'd guesstimate a 2psi stronger actuator (than new...not the old tired ones) would go a long way, but very important is the way the boost curve is programmed. If it's more linear and "gentle" it'll...

A tiny bit stronger would be OK but don't go and double the actuator's strength. Spiking becomes an issue pretty quickly, and the turbos only live for a long time if you don't over-spin them by a...

Mine did that before I decided to rebuild it. It's just gone basically. The TC clutch will hold some ( but not much) torque so you won't get the code until you load it sufficiently to slip. That's...

If they are properly remapped then that shouldn't happen.

Anyway check the lines to and from the N75 as well. If those are leaking the wastegates will see insufficient pressure to the actuators...

That was on my way to Russia...in Germany :jlol:

Only 290 km/h indicated though...roadworks ahead suddenly and also the previous owner apparently had one of the speed alarms set to 290 which...

Its raining cats and dogs here in Moscow this weekend, not a good time to try and put down 1000 horsepowerz.

You really dont feel king of the hill around here with a 550hp rs6. I keep getting...

I don't think there is a way to trap it considering the temperatures, pressures and sheer amount of flow on the turbine side of the turbo. I think engineering has done a good job to prevent this from...

People should not look at dyno PEAK numbers period. Doesn't matter whether it's flywheel or wheel horsepower, 1 is not necessarily more accurate than the other. In order to compare anything it must...

IMO it comes down to whether or not you want AWD or find it useful. If you live in a place where the sun shines every day I think you'd be happy with an M5. There's slightly less that can go wrong...

There's always a ton of variables so it's hard to give a one size fits all answer. IF the car made 450 at the crank the first time around (not quite a certainty) that means a total loss to tires and...
