On a serious note, on the US side of the forum, it is a "fact" that a stage 2 335i will eat an e92 m3 easy...

would be interesting to see the videos!...

I think the popularity of meth injection in the US on 335i's has a bit to do with that!

Any of the E92s M3s I've seen are always in the 13s and usually mid 13s too.

I wonder how the modded 3 would run against a stage 2 m3???

[andy9188]

Your all comparing modded cars to a standard car. How does that add up?

Off top of my head

E92 M3: 1640kg
e92 335i: 1600kg

Nope let me check

I think that the m3 is 80kgs more....on top of my head aswell..

[Nigelo]

If you want to maximise your potential, only run with enough fuel to do the runs and get you comfortably to a petrol station after. If the M3 is actually 80kg heavier like for like, and if you can save 10-20kg on fuel, thats a big help.

And do a big dump beforehand too.

It all adds up! lol

From BMWs website:

E92 M3 1655kg [1675kg]
E92 335i 1600kg [1615kg]

I have seen quite a few M3's going up the strip at Santa Pod.

They will run at 13.4 seconds at best. They tend to get a poor start even though they have a LSD.
They will pull you back in quite quickly in the last third if you are running with no mods.

I can run a consistent 13.0 with JB4 and non runflats and best is 12.8. I have DCT which is very difficult to get right launch wise. Once you master it, then you will get a decent launch.
I found that I took off half a second just by ditching the runflats and running at 12 psi.

Stage 2 M3 is like 430 - 440hp

Stage 2 335i could be similar power levels if running an aggressive map. With meth potentially much more..

Time to strap on a sc haha

That is completely wrong. You have seen some M3's with poor times due to crap launches!

The M3 is hard to launch, but can be done well.

An E46 M3 can do low 13's, I've done a 13.3 with a less than perfect start.

E92 M3's can do 12.7 with a good driver!

Good time.

The original question is which would be faster and I still think there won't be much in it.

I don't understand how so many bad drivers end up with M3s and go to the drag strips to prove it.

It does seem to be M3 drivers can't achieve times and 335i drivers are.

There is quite a few 335i with similar times and/or faster terminal speeds.

It will be interesting to see how the OP gets on. Won't be much in it either way on the straights.

Well I can manage it in mine.

I would say its far easier to launch a car with massive reserves of torque at low rpm than a car which is all top end power. You launch too low the M3 bogs down, you launch too high it wheel spins. Which results in a poor time,

I found my auto 335, although needed launching pretty brutally, started really well off the line.

Even a manual 335i can be launched relatively low rpm to minimise wheel spin but has all its reserves of torque to haul it away but obviously with some throttle management. It's just far harder in a low torque, high revving motor whose peak torque (what little there is) and peak power are so high up the rev range.

[phil200tdi]

But an LSD should more than make up for this at the drag strip...

Big torque means wheel spin in 2nd/3rd gear too!

What if you limit boost in 2nd and 3rd Phil?

I can only go by the 15+ M3 V8's I've seen at the pod, these seem to have averaged low to mid 13's but generally with a higher terminal speed than mine.
My 12.8 was at 108 mph.

This makes a lot of sense.

Good idea, I've got mine limited to 8 psi in 1st and 10 psi in 2nd, not bothered with 3rd.

Here's a couple of tips for you to win. I've run the strip a few times and found these have helped drop the times a fair bit. In order of importance.

1. Ditch the runflats, I run Vredestein Sessantas @ 12 psi.
2. Traction completely off.
3. Change gear at 5800rpm, as your torque curve starts to drop off at this point.
4. Don't get over aggressive at the launch, I launch at 2000 rpm. Stay cool like Fonzy.
5. Spin the tyres in the water ditch before launch, get some heat in them. Good times will come in the afternoon if you can rattle off a few quick runs, as you will keep some heat in the tyres.

This makes a lot of sense.

You did post faster terminals before did you not when you were recording slower times?

There is a kind of cross over point when you make a great start you give yourself less time to gain more speed.
