Dynamcis dyno.
2003 Audi RS6 with Oc.T chip, full Milltek exhaust with DP's. FP regulator.


1st run= 385.3HP 400Lbs
2nd run= 326 HP
3rd run = 346 ( I think)

I will post the dyno printouts when he emails them too me.
I have to say that I expected the numbers to be a little higher, the owner of the shop did tell me that the Dynamics Dyno which he shows the lowest numbers in the dyno industry and did say that if I ran my car on a Mustang dyno my numbers would be higher.
What do you guys think, also it was weird that after the 2nd run he did the 3rd immed. and got higher numbers with the heat soak effect, that was def. weird. He never floored it but kept it in 4th gear and applied the throttle smoothly as to not to have it down shift and make the torque graph jump ( huh ).
Any input from you guys with more experience with the dynos can please chime in as this is my first run ever on a dyno.
Seat of the pants I love this car it just pulls and pulls so bottom line is the numbers really dont mean that much to me I just wanted to see on paper what its putting to the ground.

Pic 1 at speed !

 

Bajo, The dyno owner is right, Dynamics Dyno shows the lowest numbers in the dyno industry. I've dyno my TT with DD last year and put down about 380AWHP with EVO stage 2, 100 cel Ruf exhaust, V-Flow. So your "beater" RS6 is about 500hp at crank!

 

Ray,

Thanks for confirming that I appreciate it. I will try to find a Mustang dyno in the area and run her on that just for comparison measures, maybe !
Seat of the pants tells me she is doing great and I am happy with the 400ft lbs of torque she is laying on the concrete.
I wish there was more to do with this car as far as performance mods, but the auto tranny cant handle much more and if it is to be done right (the only way IMHO ) would mean much more moolah than I wanna dump in her. The stuff I have in in right now wasnt cheap either and all that for a "measely" 70 hp increase.
These damn all wheel drive cars take so much power. But when the weather turns slick I praise the AWD.

Ahh, Human kind, never happy with nuttin !


Bajo

 

Nice BB, car is sweet.

 

Thank you kind sir !

 

Sweet car, have you modded the G55?

 

Nah and dont plan to.




Not yet anyway . My wife drives it on a daily basis and we might be getting rid of it. The G55 for what it is is plenty fast and the exhaust snarl is priceless.

I have dynoed a few Rs6 cars over the years and they just dont dyno well. The Tip trans just doesnt like it...

Nice car though- one of my favorites. Stealth and FAST!

 

I will say that the Mustang large roller AWD dyno's are some of the most accurate dynos available and have eddy currents that are much larger than Dyno Dynamics. That means that they can sustain consistant load better.

I researched buying a dyno for a testing business and Mustang stood out above the rest.

Another thing that you might want to know is that the pinched small roller system on the DD causes a huge heat build up in your tires. Tires compromise from the inside out.

I noticed that there is no high speed fans on the front of your car. This could have an impact on your test results if your engine gets heat soaked and if there are windage speed sensors behind your bumpers. Dinan did tests on BMW's (which have these sensors on them) using different speed and volume fans. They found that if the wind speeds did not match the tire speeds, that the ECU shut down the engine performance as much as 100 hp.

Here is a link to their testing procedures http://dinancars.com/whitepapersFile.asp?ID=9

This is the article that I mentioned:

By the way, we had purchased fans that were much larger than Dinan's 38,000 cfm.

Just out of curiosity, what driveline loss number (%) did they use on your RS6?

Brad

 

Thanks for the info on the dyno machines, as far as the drivelline loss he (tech) said around 25% was his figure.

Bajo

 

Thanks Bajo.

Check out the links that I added.

Is that the common number used for Audi AWD cars? I thought that their driveline loss was higher.

Thanks again.

Brad

 

what are the mods

 

I have heard numbers from 25 to even 35 % due to the Tiptronic AWD Transmission.
I will check the links you provided thanks for your input.

OC.t chip, Milltek downpipes, Milltek full exhaust, 5.0 bar fuel pressure regulator.
From what I know OT.c is not as aggresive as other tuners in their numbers and have the least problems after moding. As its known the Audi tranny's cant take alot of power as it is and some tuners go all out and apply the mapping a little more aggresively but OC.t doesnt.
Like I said seat of pants I love it the car feels very powerful and strong, unfortunately Audi's are heavy pigs and need more power due to that and the fact the AWD platform robs ALOT of power.
