Sharing Vbox times of e92 M3 vs C63 and ISF 60-130mph

[kbh]

Hey guys,

This is a vbox run of 60-130mph, same place and all night runs. Here's the time results, as you can see the c63 is a monster doing around 12.6sec, isf 13.5sec, my car e92 m/t 14.3sec and a e92 dct16.5sec. The DCT did another run and showed 15.8sec, I don't know what's wrong with his times but this was all stock. The owner of the m3 dct put on chip and akra exhaust and did 13.9 (not shown on the graph but recorded on the vbox) while my best time was 14.3sec all stock. My m3 is a euro version m/t while his is a us version dct. Maybe the us version has more restrictive stock exhaust and cats? I'm excited to put on my mods and do another vbox run.



here's a comparison of 997 turbos as well. the 997.2 pdk with giac tune is crazy fast. 8.19sec It's the same as a Lambo superlegerra and Sl65 black. Somethings wrong with the tuned 997.1 giac maybe boost leak or some sort

Something is jacked up about that DCT M3.

Almost like the dct car started in the wrong gear.

The c63 is one thing, but I'd at least expect to keep up with an ISF

if the dct didnt put in the right gear, it can be really slow

[elitex]

+1. I thought m3 was faster than isf.

[Longboarder]

something is off with both M3s by looking at the graph.

looks like you granny shifted on the 2-3 upshift. did the DCT M3 run with his windows down?

[JuRuKi]

Weird, my M3 felt faster than the ISF i drove

I thought so too guys! But the ISF is really faster straight line stock. it's a very close match though

yup I actually miss shift a bit 2nd to 3rd gear good eye. dct m3 run was with windows up. I don't know if euro and us version are different. but I thought dct is faster than a manual m3. the dct guy really pushed it

he was on the right gear and took off the same place. we usually do our runs in the same particular road strip. same take off usually we start 2nd gear. weird right?

Then the only other thing i can think of is that you guys were running a bad batch of gasoline. I presume temperatures are warm/humid where you are so the DME is going to pull a lot of timing.

Please dump a bottle of 32oz Torco in your tank (same with the DCT car) and do these tests again. This will ensure that even if you have a bad tank of gas, the Torco will lift the octane rating enough that the DME should provide max timing.

At a roll-on acceleration event in 2011, I saw a stock 6MT M3 barely loose to a C63 AMG with the power package and aftermarket exhaust (~ 500 HP) in a 40-120mph race. M3 was running good gas and started in the right gear (2nd) and the driver was good. We were all like wtf and very impressed with the stock M.

DCT is quicker than the Manual M3 (open's can of worms)

But here in South Africa I have run my DCT against plenty of Manual M3's and the DCT always comes out on tops.

Is it a bad tank of gas or does the C63 just perform better with pump gas in hotter weather? Seems like there are lots of reports of the M3 underperforming in hot weather.

Every magazine test I have seen of the C63 and M3 show the C63 to be considerably faster than the M3, with a several mph faster trap speed through the quarter and several seconds faster to 150 mph. Maybe in your roll-on event, the C63 was down on power and needed that bottle of Torco.

even with 60-130, the ISF shouldn't be pulling away from the M3s. There are minimum differences in HPs between those cars.

maybe your right. I know dct should be quicker than a manual. we will have a mile run in a few months here, it's time for a re match with the same gas.

it's a very close match. around 1-3 cars only difference

[elitex]

Every where you look, you'll find that ISF is slower. Once you get high in revs, ISF cannot keep up. Something is definitely wrong there. You sure you're using 93 octane?

I managed 9.79 in my stock c63 p31

I think Dlsj5 ran 10.7 in his modded m3 (non sc)

Shows what's capable with some mods.

wow 10.7 with n/a mods? i'm hoping to get my car around that time as well. i'd be happy if I do 11's

[SenorFunkyPants]

The DCT is geared differently to the MT which may account for the difference.

[Ezio]

DCT.. its all about the calibration.

what year is the car?
