Simply relaying what the chaps at MRC recommended and as to the reason why. The standard plugs even running standard boost have a tendency to throw up misfires but then I guess I'm lying there too.
1.2 bar upto 1.6 bar, not just in the RS6 but a lot of tuners change out the plugs for a grade cooler on all platforms. What's strange about this? Have you ever modified a car before?
Paul, if you follow MRC's Facebook/Instagram page you will see them comment frequently how Tesco 99 outperforms Shell's V power. They afterall have a dyno which is a little more accurate than your butt dyno and have won tuner of the year for about the last 8.
As to times, my car was hitting 0-100 in 6.2 back in February, yesterday when I tested, 6.6. You're seriously not trying to tell me that you're rewriting the physics books are you? You never tested Summer vs Winter performance Paul? Surprising seeing as you're a tuner yourself.
RS6's in Australia or Dubai, or California will not run the same performance times as we do here in Europe without running better cooling or higher octane. Best running NA cars in hot climates
ooooh, feisty
Yes I agree engines produce less power in hotter conditions and / or at altitude but @ 25c they don't all melt and fall apart.
Best fuel in the Uk is a difficult statement to justify no matter how you look at it. One of the better readily available fuels at preventing det is a better description surely??
That pic of the plugs has nothing to do with heat (well it kind of does). Overly aggressive octane booster and too much ignition advance caused that mess.
Take it back to basics, karting. When we run minimal squish and very tight tolerances on our kart it is a right bitch to fuel properly, popping, banging and farting. Open up the squish (less compression ) and a monkey could get the fuelling good enough for it to run ok. Same goes for these new breed of engines. High compression (for forced induction) high boost and optimised ignition advance for power and fuel economy. Things are getting tricky even on standard spec never mind throwing in some ecu tweaking. Everything component has to be spot (plugs included) on for them to run right. When they do, they perform very well compared to the old cossies etc with huge lag and poor of boost running.
On a standard C7 RS6 they will run with any fuel and standard plugs, after all I guess other than they guys on the forum most spend their time on 95 ron going to the shops with the odd blast for fun.
Not meaning to have a go but some of your statements and rather sweeping in nature.
