Audi S6 C7.5 Revo stage 1

[pez81]

Just had my car stage 1 by the guys at Revo UK.
Drives great, power is noticeable. Had it about 4 days so will post more once I've had chance to drive it a bit more.

On a dynapack hub dyno stock it made

547NM (403lbs)
373HP at the wheels.

After it made

427HP at the wheeks
688NM

Not seen other Revo dynos so don't know if this is similar.

The operator said the torque is the same as the crank, not sure if he meant that was crank or wheel.
I know shit about dynos so hopefully someone can help me out there.
Would you measure wheel HP then crank torque?

This is my first tune in a car so it's all new to me.

It pulls like crazy and drives very smooth. Doesn't feel like a tuner car. Just more power.

Had some fun with an M4 and an SLS on the way home too which made the long journey more enjoyable after 20 miles of 50mph speed safety zones.

It has more pronounced crackle and pops on overun too which I love.

Car is otherwise stock just a stage 1 development tune on it.

Their S7 C7 is a stage 2 making 560 and 750? NM I think.

They were kind enough to give me a car for over week in return for the tune. The ECU took a bit more time or something I can't remember what they said.

Just had an independent dyno done (see image)

On the Revo stock map it made 420bhp
And on 99ron it made 485

The torque number is the reason I had it dyno'd as it felt a lot more that my original dyno.

That made 534lbs and 406 stock.

So about 130 flbs

What do you make of the dyno chart compared to others?

It's making big torque way down now and remains around 100lbs thought the rev range.

What ever dyno you look at its making 60bhp and the flywheel and good torque.

Drives brilliantly too.

Was hoping for 550bhp but I guess it depends in the dyno, car, the tune.

Will try to get to santapod this year and see what she runs the quarter in.

Has anyone had their s6/s7 independently dyno'd before and after?

Looks good Tom,

I didn't know anyone in the UK had cracked the C7.5 4.0 Management systems. Hadn't really considered REVO, had been looking at APR mainly.

Have you modified anything else?

[pez81]

Drives great. No all drive train is stock otherwise. APR appears to make bigger headline figures and I think Revo makes more across the band. But I know little about this stuff. Realised why it made 420 stock today instead of 450. The stock file on the SPS must be loaded with an earlier C7 file. I'm not sure if that's an issue or not.

373awhp seems really low for a hub dyno. Aren't these cars underrated from the factory?

With drivetrain losses it made 450ps I think at the crank. So right on what Audi lists

Thanks for posting. Glad to see someone other than me considered REVO. I am still trying to decide
