Show us some real balls and hold it against the rev limiter for as long as you can. I will do the same thing with the M50 in my 525iT.....we can play a game of chicken sorta.... ;) (smiley face for Gayle so she doesn't mistake my tone)

quicktime played it for me,you revved it to about 6700 or so and already had you foot off the throttle,whats the point?.You should go play with the guy who held his car at 5500 or so for 15minutes,not moving.

It will outlast the M50 with it's eyes closed. Last year when I stll had my Schnitzer 535i, we drove back from Spain at night with the speedo hitting the 260 km/h constantly and the rev counter hitting over 6.000 rpm for over 2200 kms and 15 hours with only stopping for tankstops ( a lot of them!!!) , it didn't even get past the middle of the temp gauge.

I don't want to ruin your story...

But many 92 M50's with their stock double valve springs, short stroke, thick connecting rods and walls are revving to 7500 rpm on stock internals in the FI crowd. You have to be out of your MIND if you think a M30 is going to out rev an M50. That M30 will chew up the mechanical valves in no time.

The Dinan Stage III refers to the suspension on my M5. The M50 in my 525iT is boner stock.

The M30 has double springs as well. It's a toss up. If you have a weak rocker arm in the M30....SNAP!!!!

The M30 does have double valve springs... however the M50 non vanos springs are an upgrade to even the S50 springs... and the S50 springs are knowingly stiffer than M30 springs... so thus M50(No TU) > S50 > M30...

The other big factor is the stroke. Either way, it takes serious head work to get a 7200rpm revving M30, while an M50(No TU) will take 7500 rpm without much issue.

Either way: Scott H wins, and that was a WEAK rev limiter bounce ;)

I would be scared revving my m30 engine that high. 6000rpm is around the limit for myself. The car revved to around 6700rpm, is that where the cutout is? I don't think I've taken it to cutout before, so I don't know whats it like.

12-10-2005, 05:40 PM
This is funny.

M30 guys you need to get a bit heavy on that right foot, and use all those revs. If the engine keeps pulling I keep pushing it. If they float, then you will hear it, sounds HOT when it happens.

My m30 pulls quite nicely up to the 6000rpm shift point on the automatic. If youre losing power at 5500, there might be something restricting it...unless my car is modified and i dont know it :D

p.s. Check your distributor cap, when the distributor cap on my brother's e28 m30 needed replacing, the power dropped off at ~5200 rpm.

then this video is for you to try :) ... cuts off at 6700 but the normal oparation is upto 6500. I think the RPM meter is not accurate at high RPMs. I will take another video when I install the 6800 limit chip.

reving the engine cleans the carbon build up and also cleans the injectors due to the vaccume and pressure from the pump ... its all good for the engine ... even with carborator engines its healthy ... I rev the engine to burn rubber almost every day ...

is close to full warm when you do this everyday! You run that thing too hard before things fully warm up and you could really start wearing critical things in odd ways. It won't kill it right away, but over time you can end up with problems.

Haha what are you talking about?! You reved it to 7000 or closer to 7800...

what?!

Stop being silly. If you do it just right, rev it to "7800" and get out in front of the car, grab a baseballl glove, you can play catch with the pistons.


Also: Of course the temp is in the middle. You could practically run it without coolant at that speed. Joking, but thats the point.

I just took a look at your cardomain website....

How are you going to go about mating a 6-spd from an E39 540 up to your M30 in the 535?

Also...post some pics of the 850....it looks like calypso....my favorite red.


Things to come:
this spring I will install a turbo/intercooler. Will give it about 100more hp to the wheel at low boost; enough to keep up with e39 m5. Once my tranny goes I will mate it with a 6 speed transmission from an e39 540i.

I am debating a widebody kit. not sure anymore though.

I would also like to lower the car more, and I am consider air suspension so that I can literally park it on the ground when not driving

Scott H
12-11-2005, 01:51 PM
I thought revving the engine to the limiter and bouncing it a few times was pretty silly. Especially since the rev limiter is RAISED with the chip. I wanted to figure out exactly how far grave would go. I mean, if it's so safe to do it often, then why not just go for gold??? The truth is I have nothing to lose from my end.....the M50 in my 525iT is a throw away as far as I'm concerned. The engine is useable but tired, and the tranny is completely shot. I am rebuilding the M30 from my wrecked 535 and putting it in the wagon in early Jan.

Was my challenge stupid.......yes, completely
Was it all a waste of time......yes, completely

I was just trying to connect with the current crowd a bit more than I was last week.... :D

By all means, if the challenge must go on, I'm game. I wouldn't make a proposal if I could not follow through! :D

i made that a year ago. i lost interest in modding the e34 when i bought a bike last february. forced induction and swaps were too much work/$$$ for the kind of acceleration i wanted, and it's a lot cheaper to simply get a 400lb bike with 100 hp at the wheel. it has since grown my appreciation for the car in a different respect.. i no longer see it as a performance sedan, even though it does handle ridiculously well etc; i see it as a luxury cruiser.
anyway, couple pics of the 850

I've only ever gone 140mpg in my 7, passing cars doign 100km like they were parked is definatly an uhh.. interesting experience. Yes I got video to proove it too if your going to start hating on me :(

Can't wait for the chip and the snow to disappear.
Damn, I have trouble getting 25mpg.

I agree paul, m30 engine in my e28 m535i manual says max permissable continous engine speed is 6000 rpm, why push harder when peak power is at 5700 in the e34 m30 with a stock cam.
