IanH's 955hp V10 Audi RS6 - Another Car Diary!
Discussion
Great stuff Ian.
Any vids yet of it 900bhp form??
What did they do to strengthen the box?
I assume a stage 2 car's gearbox will cope time and time again with just a software upgrade?
Seems a great value package even on stage 2 as a tourer and some fun on track! Have you done Castle Combe in her yet as I always attend the Audi Driver magazine event? It's quite a bumpy track and I suspect the straight is a bit too short before you start braking into Avon Rise before Quarry bend!
I was out in TSR's 550bhp Cupra last October which is racing this year.....thought that was rapid ......900bhp must be breathtaking!!
18k looks like good value for what's available......you must have a good job!!
How does it compare to a tweeked GTR??

Ok so lots of questions, I'll answer them all separately - Any vids yet of it 900bhp form??

Vids - Nothing yet, it'd break every UK speed limit in less than 4 seconds of full throttle so taking a video probably isn't the cleverest of things so I'll wait until I get back over to Germany in the Summer.
Gearbox - Uprated friction plates (exedy I think), uprated input & intermediate shafts and basket, uprated valve body assy for better control of the shifts and uprated torque converter. The OEM gearbox will cope with stage 2 all day long, MRC haven't yet seen a failure of one.
Castle Combe - I'm waiting for a set of AP Racing 410mm discs/calipers before I go back out on track as the OEM sized AP Racing discs I currently have would struggle I think.
GTR - No idea
The last GTR I went in was my friends which had around 650hp but it was 4 years ago I think so I cant really compare it, although the RS6 gearbox is slower than the DCT type one in the GTR, plus there's no launch control etc so it'll probably be slower from 0mph but from 100mph+ I'd guess it'd really pull away with nearly 300hp extraOn Friday I'd noticed that, either the car was a bit down on power or that maybe I'd got really used to it, after I took a couple of friends for a drive. It was still quick to them but it felt back at mid 700hp levels to me.
I logged some values with VCDS and saw it was pulling timing due to elevated intake heat which was unexpected as the day was cool and it was the first "full throttle" of the day so it wasn't heat soak. After some serious head scratching I found the most unlikely culprit - I'd been showing my friends the Aquamist Water Injection gauge which lives in my glove box and had taken the protective cover off and forgotten to refit it before closing the glove box and at some point the pair of 3D glasses I keep in there (for the cinema) had bumped into the On/Off button on the front of the gauge and switched off the WI, which explains the higher intake temps. After a pretty epic actual facepalm (it hurt) I switched it back on and took it for a spin and was back at 900+ level.
So, I've decided to move it from it's current position. The reason it's in the glove box is that I don't need to see it because the water/meth "reservoir" is my windscreen washer bottle so I have the cars own level sensor to tell me if/when the level is low. Plus there is literally nowhere else "easy" to put it without using a ugly A-Pillar or Dash pod mount. I've seen a car with it in the front ashtray which looks great but it was a huge pain to get fitted and the air vents are narrower than the gauge so I can't use a Vent Gauge either.
Burwood - That was the plan about 7-8 months ago but as mentioned in a November '15 post the seller (German eBay) dropped out over shipping issues and the moeny I saved allowed me to buy the uprated Gearbox instead.

I popped back to MRC yesterday to have a bunch of "post re-build" niggles sorted and then stayed for the AudiSRS forum Dyno day today where it made a much more respectable (and expected) 890hp and 1080nm which is more like the figures I was expecting rather than the 780hp at the earlier Surrey Rolling Road which I found out was caused by me accidentally switching the water meth injection off, doh!.
I did about a dozen passenger runs in the end too which are always a highlight for me

I imagine it is used for both, that's what I did when I ran WI anyway
Yeap thats what I do, methanol (or similar) is already used in most screenwashes in a very diluted mix (<20%) along with all the detergents, colours and scents etc so I've effectively got super strong "pure" screenwash now I actually find it's better at cleaning the screen than the pre-mix Halfords Purple screenwash I was using before too.
Update time - New brakes arrived!!!!
AP Racing 410mm discs mated to Radi-Cal CP8522 Calipers mounted on custom made brackets by BG Developments who do all of AP Racings Customs work. I've also got AP Racings DS-25pads (Ferodo DS2500 compound), HEL brake lines and Castrol SRF fluid.
I'm doing the ASDA charity trackday again on the 6th so, now I've got an extra 180hp over last year, we'll see how they cope with multiple 175+ to 30mph stops. Last year when I was at 730hp the OEM Caliper with AP- Racing 390mm discs, DS2500 pads and ATE Superblue fluid it did 49 160+ to 30mph stops with only a tiny bit of fade in stopping power but a longer pedal travel throughout the day so I'm hoping for much better from these.
Once I get these fitted on the 2nd I'll put up a full review with more pics and fitting guide etc.

Absolutely true story this, I went to Maidstone Exhaust Centre to look at having the boxes removed and got chatting the owner and told him the power and a mechanic 5ft behind me did the coughing "bullsh*t" thing twice!
I didn't act like a mature, calm & sensible person and instead reacted very poorly with a choice comment of "Does Mr bullsh*t want to see the dyno, does Mr bullsh*t know *anything* about tuning a twin turbo'd 5L V10, well..................thought not, ****" and I thanked the owner for his time and left.
I'm a little more thick skinned now
Haha. That did make me laugh.

I had Project Mu on my R34 and rate them highly but they don't do anything for this new Radi-Cal caliper yet. I can't really have full track pads fitted as this is my daily driver (hence the DS2500's) but I'm looking at getting a spare set of "track only" pads and discs so I'm looking at Ferodo DS3000, Carbotech XP10, Hawk Ceramic and Cobalt Friction XR1/2 for those (the only companies currently making pads for these calipers) or asking AP themselves to make me a set with a different compound (APF 401/402).
