Picked up my new car this weekend........955hp V10 Audi RS6! (HP figure updated 08/10/22)
- Thread starter ianh
- Start date
Say it weighs 4000 lbs and 920 hp, thats roughly 9.3sec at 143mph 
the 2015 Mustang GT weighs maybe 3710lbs (purely for comparison).........but Gibbo will know for sure.
the Audi is therefore fairly heavy, considering this it's really ****** quick
finally it's Torque is massive ! that's the same as a 468ci big block Pro Street Chevy

Lovely car.
Never tire of seeing German cars with crazy power.

Mal X - It's closer to 5000 pounds (2.3 metric tons) with fuel and a fat driver
Just back from the RS246 Forum dyno day and what a rollercoaster - Here's a bunch of valid excuses -
Just to be clear, I know it has a massive heat-soak issue on dynos (caused by crap intercoolers soaking up too much heat) which it doesn't have on the roads.
However, on a dyno it'll run low power due to high intake temps unless you prepare the car/dyno properly. I didn't bother with that so my utterly crap "pre-run" prep, was "blast around like a loon, leaving it off for 20mins to really soak up the engine heat, have it idle for another 20mins creating more heat and then not cool the side mount intercoolers down by only using a single centre fan for the engine bay, which isn't where the heat is an issue, leaving the intercooler sat in static air"
After all that it made.................780hp!!!!!!!, Charlie them spritzed the IC's with a little water (but still no airflow) and got 810hp, so 30hp back just with a bit of water thrown on them.
To be fair, all the side mount Intercooled cars suffered on the dyno due to lack of cooling airflow as none made their "already dyno'd elsewhere figures" by an average of about 4-7% less.
Am I gutted, not really as it's a dyno/static air issue, not something that happens on the road. The dyno result from MRC is on a dyno specially setup for side mount IC'd cars with 2 independent fans just for the sides and another for the centre and even they'd said that my crap IC's were causing heat issues after 3-4 runs (dropped to 880hp).
I'll still be looking for new ICs though but the current cost for a set............£4200!

How much strain does this put the engine under?

near 5000 lbs
now that is heavy you can get someone to fabricate larger intercoolers for it, because i was looking at earlier on, but if it's producing much more HP on the street with far better ventilation (obviously) then i guess it's ok.
or next time you go for a Dyno test, buy two really big fans first and an extension lead as well.
in the States they have mobile Dynos, so you can do it outside on a cold windy day, but i've just Googled it and i cant see a similar service here in the U.K.........typical
it does of course for bragging rites really need to be 1000 hp, it sounds nice doesn't it..................1000hp
your car with a full exhaust is what's called a ``Street Sleeper``, because you might expect it to be say 600HP, but deffo not 1000
............i think it's quite funny, great car !

Have you not considered Water/Meth injection? It would be a lot cheaper than new ICs and help reduce the heat soak issues by quite a margin and it also nets a respectable power gain once mapped for so would see you past the 1000bhp marker
Frozen - Aquamist HFS-4 already fitted running 50/50 Meth & Water.
Mal X - Intercoolers, it's another "lack of space" issue as they can't be made any "bigger" but they can be made deeper, although each one is flowing 450hp through something A4 paper size by only 3in deep.
Unfortunately mine are a bit "industrial" so the metal is very thick which retains the heat and only slowly cools down unless you're driving. The uprated £4200 ones are from HS Marstons who are an aerospace company and they use a similar core to the F1 cars from a few years ago (hence the price) which flows the same power but is amazingly thermally efficient compared to mine.
With a proper Dyno set up (side fans) and car setup (let everything cool down before the run) it shows the power on the dyno as seen from the MRC result but on a poor dyno setup with poor prep, its shocking how much the heat affects it.

ScoobyDoo69 had a similar issue on his Impreza and mounted a slimline fan with a switch to the underside of his IC to pull air through while stationary. I'm pretty sure he said that worked really effectively at bringing inlet temperatures down on the dyno
well then you're ok, therefore that really expensive intercooler isn't worth it just for Dyno testing only.
but to aid cooling quite a lot, low profile bonnet ventilators will do the job, but i would buy a spare bonnet and modify that and keep your existing one untouched...........there's some really good ones there

Having been in it when it 'only' had 7xx bhp it was ridiculous. Relentless.
I can't wait to have a ride in it now!

Well it certainly sounded good even at 100-130bhp down! Managing that much heat in an engine bay that tight was always going to be an issue but it really was eye-opening to see just how much of a difference it made!
Given you're not out to build a dyno queen and definitely do use it on the roads, the heatsoak issues probably aren't the end of the world and whether or not the new ICs are worth £4200 is something to think carefully about. Perhaps when the other items you mentioned are sorted out it could be worth it so you feel it is "finished"?

Uprated gearbox
It'll take 1300nm apparently (950lbs/ft) which is what Sportmile in Poland are running in their 1100hp beast. They've had to chop the chassis to bits to make the GT42 turbos fit so in a crash it'll implode horrifically as the chassis crumples!!
