has anyone raised the rev imit on an e36 m3?
have seen something on the da motorsport web site that rasies the rev limit from 7600rpm-8200rpm.is this safe to do?have read somewhere about evo engines having a con rod bolt weakness which i would have thought wouldnt be great for higher revs.

the product:MAXIMUM ENGINE SPEED MODULE

- DA MOTORSPORT offers a maximum engine speed unit for E36 M3 Euro 3.0L and 3.2L. With our maximum engine speed module you can increase your maximum engine speed from 7600 rpm up to 8200 rpm on the 3.2L M3. On the 3.0L M3 maximum engine speed can be increased 7200 rpm to 8200 rpm


- Increasing maximum engine speed on E36 M3 allows two things: more power and higher road speed in each gear. Higher road speed in each gear means you do not shift up as early as your competitor and gain time


- Installation of the M3 maximum engine speed module is easy and takes 30 minutes. Your ECU will NOT be sent to us. We send the module and installation manual


- Price of maximum engine speed 270 USD


if its safe to raise the limit can the limit be raised when having the car remapped rather than paying extra for this module?
is there any point in reving the std engine to 8000rpm or is it best to fit higher lift cams to make use of the extra revs?

just after info really

e36coupe.com is actually a very good site and full of knowledgeable chaps who certainly know their onions.

Drop Dunk76 a PM. He is a moderator on there and if you're nice to him, he'll sort you out access to the site.

Plenty of the lads on there race their M3's and I've never heard any of them talk about raising the limiter. Remember, the S50 is a highly stressed engine as it is. Simply raising the limit without spending ££££'s upgrading the internals to cope, is a surefire way to make the motor go pop!

If you want, give Munich Legends a call. They have an excellent reputation and will give you impartial advise. However, unless I am very much mistaken, I've just saved you the bother wink

My 1st M3 revved to 8k plus with no problems on a superchip. Plenty do run at 8k.

Ah, but how many miles did you do in it before you err, put it on its roof? smile

Like I said above, a chip is all well and good, but shirley, if the motor could rev reliably to 8k+ it would have left BMW like that?

Each to their own, but I'd rather spend the cash on sorting the handling than turning the engine into an unpredicatable grenade.

They will rev to 8,000 but as been correctly stated on here the engine is already highly tuned, personally I wouldn't do it unless you are also going to be upgrading the rod bolts at the very least, they are known to go!

Exactly. Besides the M3 isn't exactly renound for lacking go, so why risk grenading the engine for a barely perceptible increase in performance?

erm i was only asking for info(embaressed look)i like to find as much as possible about a car before tuning one.
like you say the car is plenty quick enough in a straight line.would be money more well spent on a pair of konis/eibach springs/arb's/powerflex bushes/atb diff and some bigger brakes and fresh rubber

Sorry old bean, didnt mean to sound agitated.

IMO your money would be much better spent on suspension/brakes - especially, the car in question as a few miles on the clock.

Have you bought a car yet or are you still looking?

Did you PM Dunk?

I was the same. They still let in people manually over there so it takes them an age to get through all the new recruits. Definately worth while though, you'll find a lot more info on there than you will here.
