E46 M3 supercharger

[2002_M3_Racer]

ARe there superchargers for the e46 m3's? if so how much are they and how much power do they add?

[Inaux]

RMS is developing one that will add 100 hp

[Dinan540i]

Hopefully they fix my tranny clunk first. Personally I would not put an sc on if they paid me to.

SC will void EVERYTHING on your drivetrain warrenty. This car is not cheap to repair. They will don't fix the clunk for free after you put on a blower.

ESS Tuning also has one for the E46 M3 i believe...
(not sure if its already available or not,
but output is at anestimated 415hp )

That is not correct sir, adding Supercharger to your car voids nothing. In order for a dealer to refuse a repair under warranty due to aftermarket parts they MUST show it was the aftermarket parts that caused the damage. You can go to www.sema.org for more information.

Hope that helps.

True, but everyone knows that the dealer will say that it was the supercharger that caused the damage, they don't want to do anything for free.

1. SC adds more HP
2. More HP means more engine stress.
3. More engine stress has caused _________ to happen.
4. Void warranty. Have a sssssuper day!

Well, I have a supercharged e36 M3, and luckly I had the extended Dinan drivetrain warrenty. (My two years are up now actually) So far that warrenty has covered some of the following, all of which the dealer would not cover and blamed the blower.

1. TWO snapped diff bolts. (You think your clunk was bad)(Covered)
2. A melted engine harness. (Covered)
3. Blown cats after only 18,000 miles. (Not covered)
4. Siezed the bearings on the blower and blew it. (Covered)

When the blower went, it stopped flowing oil which backed up into the intake manifold and caused a engine fire, which melted the engine harness. The total repair bill was close to 6,000. Dinan picked up most of it. I had to pay labor.

Superchargers will cause more problems and cost you more money. However if you have the $$$, go for it.

I've twisted sway bar links, broken shock mounts to. This all on a car with less then 20,000 miles. Granted allot of those miles are on the track. It puts allot more wear and tear on your car. Plus you have the clutch to think about.

Personaly, I also think you are ruining the real M motor by putting a blower on it. The e36 M3 in the US never got the real deal, if it did, I doubt you'd see 95% of the blowers you do on them. The US e36 was underpowered for its chassis design. The e46 is not. I would never dream of putting a blower on my e30 M3, nor would I ever put one on a e46 M3 if I had one.

Putting an SC on a motor that already sits at 11.5:1 compression is pure stupidity. A smart tuner will offer new pistons with the supercharger kit in order to allow for boost pressures over 4psi...otherwise don't even bother.

[John]

True, you will need to lower the compression to gain any real numbers from the blower.

I would basicly only trust Dinan and AA to do the job right in terms of forced induction. Neither of the two companies cut corners or push things to the edge. With that said, I don't think your going to see a forced induction kit for the e46 M3 for a LONG time, and when and if we do, it will be very expensive. At least 20k, give or take a few 1000.

I think the real place to look for more HP is the M3 CSL, find out what BMW did to strengthen up the engine enough to raise the RPM limit to 8500? and get that extra 47hp and keep the motor NA.

The car did not have 47 hp extra, 7 more bhp than 343bhp stock. All the speed gained on that car was by weight reduction. Many people on this board don't undestand (not talking about you) that weight is hp and that all that matters is hp or toque per per pound. There's SO much weight that can be shaved out the E46 M3 it's not even funny. The simple things that come to mind: HEAVY back seats, seats that are fully powered and heated add in the neighborhood of 150 lbs, the moonroof is heavy (I have no moonroof). Then you can start lightening the body components, taking out the radio, ac, thinner glass, etc. The CSL comes within 10 seconds of the 996 GT2 on the nurburgring, currently the fastest production car in the world. So, with mostly weight gaining measures, a stiffer suspension and wheels that were almost slicks it nearly got the top time at the ring, but then again it's not a production car, yet at least. Why take an engine like the S54 and use forced induction is beyond me.

True, but who wants to drive a stripped M3 on the street? Weight reduction is an easy way to make a car faster, but usually at the expense of luxury and convenience.

I think the Murcielago is currently the fastest production car...0-60 3.8 (GT2 is 4.0) and top speed of 205 MPH (GT2 is 198 MPH). I'd still take a GT2 over a Lambo any day tho...computer is all it needs.

I agree <b>100%</b>

But anyone who is willing to sacrifice reliability for an sc shouldn't mind. As for fastest, I meant on the Nuburgring, not straightline which there are so many cars very close. With a topspeed of just 205mph, the Lambo doesn't have a claim to that record IMO.

does anyone know if dinan is planing to come out with a supercharger for the e46 m3?
