M3 0-60 Times

[Nicks_M3]

Hey guys, I'm kind of new here, bought my frozen black e92 m3 last October. I've done some modifications to it over the winter including AA pulleys, afe intake, vrsf test pipes, a custom tune done locally and rear seat delete. A bunch of other non performance items as well.

Got a chance to do some 0-100 (0-60) runs today. Full bolt on e92 m3 ran 4.6 on 94 pump gas and bone stock 335i on 91 ran 5.35. That 5.35 was by far my best run in the 335i all the others were 5.7 (very consistent car!). M3 was all over the place, did a few sub 5 second runs but most fell around 5.1-5.3.

Interesting to see that after all this work both cars best times were manufacturers suggested times despite the maybe 30 whp gain on a stock m3. Though the speed graph noticeably more linear on the m3.

So my question to you guys is, what can I do to improve the times on the m3. 4.6 is kind of disappointing to me. My launch strategy was mdm mode, everything set to max aggression and just floor it. Manual mode on the 335i with short shifting dominated but I could never get a good up shift on the m3.

I think my next strategy is to go with solid rear subframe bushings, start doing some more weight reduction and switch over to cup 2s or r888r's to improve on the time. Any other suggestions?

It's an older car probably has lost a few wheel ponies, plus most manufacturer 0-60 times are from a 1 foot rollout. Personally I think 4.6 is pretty damn good.

What's your elevation? Tires also are a factor. I assume you are 6mt? There will be a decent difference between DCT and 6mt. My guess is the mileage and age will probably more affect the shift speeds than the HP.. These engines shouldn't lose much power if we'll maintained, new belts, gaskets, plugs, fresh oil changes every 5K at least, etc.

Car is dct. Pulleys came with 2 new belts. I've done about 1500 kilometres on current oil. Did new spark plugs when I bought the car and ran 2 full tanks of 5 in 1 cleaner. I feel the engine should be mint. I wonder if I may not be on 240/241e and in fact an older outdated version.

The thing that tells me there's a lot more time to give is the graph itself. 30mph happens at 2.10 seconds, almost half way. 30mph in the 335i is 1.80. That tells me the car is severely limited to traction and not necessarily the power itself.

Or the twin turbo 335i delivers a bunch of torque quickly

I'm at sea level and with 40,000 Kim's on my car, DCT, new AD08R 275/35/19 tires and launch control at 5500rpm I pull 3.8 & 3.9 seconds to 60mph.

No way... maybe on the m3 ego Speedo but from a dig on a vbox you're not catching sub 4 without major modifications

According to a stop watch i managed to run ~4.7 to 100kph I just changed my tires and will do a test with vbox to get accurate numbers. i have stage 2 tune +gts dct tune with air intake.

Believable if the car is full bolt on. Sub 4s fbo m3 is not entirely out of the question.

[dmk08]

You think you're going to get the best time with the M mode nannies on? Do you even have euro mdm coded?

Have you tried launch control?

[pbonsalb]

Traction is the biggest factor. Some tires, streets, dragstrips are stickier than others. Use a set of drag radials or R compounds for the most stick.

Another factor is launching but those of you with launch control doing the hard part don’t need much skill there. And a big factor is shift times, but those of you with DCT don’t need much skill there.

If you plan on doing a lot of drag racing, I’d use stiffer subframe and diff bushings.

I find right now my biggest issue is getting as close to 8400rpm as possible without hitting the limiter. A few times I've banged into the limiter and one occasion I short shifted 2nd nearly 400rpms short! 0-60 in this car is just 1 shift.

[pbonsalb]

I use 8600 rpm, but have a 6MT so I am not going to win any 0-60 races against DCT.

We used a G-Tech ProSS meter. One of the car magazines got some numbers under 4 seconds as well.

[pbonsalb]

Yes, one. One, perhaps the same one, also trapped 114.8. But every other test, or almost every other test, was slower.

[Eja144]

If you're just flooring the car from a standstill at 0 RPM, I imagine you're losing time while the engine revs up into its power band.

Also MDM will cut power when you lose traction. Happened to me merging from a yield sign last week. Tried to punch it in first and tires started to slip, then.... nothing.

[pbonsalb]

The Euro spec for MDM is a lot better.

[Marrkvp]

What kind of tires do you have?

[acarr6]

Nick, have you changed your Kinforest tires yet? That would be the first thing to address.

Summer tires, not the best thing, not the worst I've ever driven on. Dealer put on cheapish tires when I bought the car. Never bothered to change them because well, no one will buy them LOL.

[RedScytheM3]

Get your tires nice and warm then use launch control. Launch control with a proper hook up is much faster than stomping the throttle in MDM. As others have said, in MDM the computer kicks in at moments you don't realize and cuts power
