As above.

I have a 2018 C63 non S bought brand new broken in properly currently 3k miles. Last night had 3 pulls against a stage 2 S5 (2016 supercharged 6) and got pulled 2 cars from 40-120 each time. I actually had a stage 2.5 APR s4 and I know they are very quick with near instant maximal power but I didn't think from a roll it would stay with the twin turbo 8. I also am not an incompetent driver... so what is it? Should I get my car checked out? He should be making around 400whp and 360wtq. Also think they are about 100lb heavier.

I walked a stage 2 s6 from a roll and walked around him after i hooked when we did a dig, maybe driver mod is a thing

rekrul

Yeah... I mean they are both autos... so I can't imagine driver shift points makes that much of a difference. This has me seriously worried about my car not making enough or stated power.

raudiace4

LOL looks like you need driver mod.

I have zero trouble walking stage 2+ 3.0t Audis (S4/S5) with dual pulleys, and also no trouble walking tune and downpipe S6. Bone Stock C63s coupe.

Alex98

lol naaaah bro they're both autos. nooo way bro can't be a driver mod

KJ

You guys both have the "S", he only has the regular C63 (non-S).

Granted your not a S model but him putting 2 cars on you? That is A LOT!. I would have your car checked out. Point of reference my close friend has a 2015 s5 6 speed manual with the APR stage 2 plus kit. My c43 with a tune only v2 NOT even V3 that i currently have i put a car on him and that was from a 50-110 run. As we got faster i kept pulling more and more.

Alex98

An S variant I doubt will go from -2 cars to +2 cars, thats over a 4 car difference

It seems like some things never change... including people talking trash behind the comfort of their computer screens. What I'm saying is I'm not a newbie to DCT etc have driven M3's, S4's and have had my cars meet expectations with regard to what they should pull on and not pull on. As I've been driving performance cars for nearly 12 years. So I don't think there is enough driver error here to account for the mismatch hence my concern. Btw a Stage 2.5 S4/S5 will trap in the 116-119 range... so you shouldn't be walking them with a non tuned C63 as I believe they are trapping in the 119-121 range.

Out of curiosity Are you utilizing full auto shift with your rolls or using the paddle shifters manually? The one thing the S4 did have was you could manually downshift to the ideal gear and then the upshifts were automatic this is not present with the C63.

rekrul

6spd vs DSG is a big difference tbh... I am not well versed enough with the c43s to know tbh.

RDOCA

Of course it is.
Since you don't have race in a non S you should be in S+ and auto and paddle shift to the start gear you need.

I got walked by a mk7 stage 2 fbo gti. I had a stock C63S sedan. Looking at the torque curve and power to weight ratio, it kind of makes sense. I also lost to a Charger Superbee SRT. Both were from 30 rolls. I am going stage 2 so I should walk them now

vaelin

Even in auto, you can hold down the downshift paddle and the transmission will downshift to the lowest practical gear for your speed. If you're just mashing the pedals while in a cruising gear, you're losing the half to one second it takes for the ECU to figure out you want all out acceleration and downshift for you.

Rayc63s

Maybe he brake boosted and you didn't? Cheapest way to see if your car is performing on par is to buy a "Dragy". Do some pulls in "Mexico" and you can compare your times. Dragy isn't linked to a vehicle so your buddy with the S5 could test it as well.

KJ

So you didn't even bother down-shifting to the right gear when you rolled against the S5?

rekrul

Negative. I downshifted then did a rolling start on 3 honks. I manually shifted however. The DSG in the S4/S5 will auto upshift I wasn't aware that you could downshift to the lowest gear in auto mode in the AMG and essentially do pulls with auto shifts without risk of bouncing of the limiter which is what I did on the first pull as I was manually shifting. The second two runs I did not bounce of the limiter.

raudiace4

I think you should trade in your C63 for a tuned DP B8.5 S4/5 then LOL

Stage2+ cars will trap 116-120 sure, on a perfect cool day with ideal DAs in perfect condition with a mix of E85 and 93 or straight E85, not many off the shelf bolt on 3.0Ts will do that realistically. Don't let the AZ 1/4 mile sheet skew you into thinking the all simple DP 3.0T cars can do that without upgraded fueling, cooling etc. This is from my experience having owned two different S4s that were FBO (2012 and 2016)?

C63s trap anywhere between 119 and 122 stock, so the Non S should be within 1-2mph of that. Either way I expect a bone stock non S version to be able to handle any stage 2+ 3.0T. Unless your car is being heat soaked, driver error upshifting manually without letting the car do it's thing in Race mode, or the car you were running is a world record holding 3.0T with ported blower, upgraded throttle body running straight E85 trappng 124+ in the 1/4.
Heat soak, is a much bigger factor for that little blown V6 compared to M177, and the top end even tuned 3.0ts fall on their face where even the stock M177 should keep freight train pulling.

You should run him again in race mode, from a 50 roll in 3rd and if you still lose then just go buy a DP S5 LOL.

rekrul

I think my main error was to try to manually shift. I will try that the next time around. For the record I did have a stage 2.5 s4 that trapped 116 on 93... no cooling upgrades. Also with regard to the pedal it seems to have an additional click to totally depress it. Is this normal?

JaeJin Sohn

I usually short shift manually during pulls because our turbos r so small that it dies off at the top end. I usually shift around 5.5k+. This is just my assumption based on looking at the torque curve, I don't know if its any faster doing it like this... Also, some Audi/VW tunes allow you to change the psi. The gti I ran against cranked up to 35 psi against me lololol

vaelin

Non S model doesn't have Race mode, afaik. But that doesn't change much.

C63SVERT

ive owned a ton of cars and i can tell you it was the same with my AMG GTS, the turbos are SO small. my c63S falls on its face at 5800 rpm's. you can just feel them roll over. Im not suprised at all. ESPECIALLY if its got upper and lower pulley. Even with a tune our cars have great low end, but not nearly enough peak power. tune yours and see how it goes

raudiace4

That could be why, not sure if non-S versions have race mode but I'd leave it in that mode, use downshift paddle to get to 3rd at 50mph and gun it from there and let the car shift up. 7 MCT is not great at pedal responses compared to DSG trying to do it manually is hard to time the shifts so that it will actually up-shift when you want it to. Do you mean Gas pedal or shift paddle? AFAIK the gas pedal has a switch that gets activated at full depression , sometimes referred to as the "kick down switch" you will be WOT before hitting that, the switch just triggers the car to get into lowest possible gear.

RDOCA

Gas pedal or Shift Paddle --there I fixed that for you

raudiace4

Ah yes oops, silly me.

rekrul

Yeah I did notice the kind of fall on its face power band. Interestingly the s4 was similar until getting tuned. Thanks for the info guys. For a moment I was depressed. I tried some runs in full auto mode and there is no way this car is not faster than my tuned s4.
