Are there any companies that make or are in the process of making a super or turbo-charger kit for the E46 M3?

For superchargers;

AA Tuning www.AAtuning.com is coming out with their version next year.

No turbocharger kit is avialiable

To be honest to get any serious gains with Forced Induction and doing it right will require a rebuilt shortblock. Compression should be dropped below 9:1, and should also have forged internals. Anything less and one bad batch of bad gas and your motor could grenade. Dave.

Would anyone let RMS touch their car?

dont go there man!
if u want to gain seriouse power do this (if u have $$$)

1. full exhaust system including headers
2.Air box
3.cams
4.pullies
5.Irriduim plugs
6.3.91 gear ratio (recommended)
7.ECU up-grade for the above!

thats it man!:buttrock

Jon, I wasn't attacking. But I wonder with as much "R-n-D" that RMS does on CUSTOMER cars, if they are a choice or not??

I am waiting to see what AA, Evosport, and ESS turn out. The ESS kit has been in development for quite some time on thier own cars and a couple of race cars.

I think we all want a good set up for that kind of money!:clap:

I know you werent attacking. I wasnt really recommending him to RMS but just something to look at.

AA has started on their prototype and all I know is that its not a customers car.

Cool. It's nice to know that they are not using a customers car for testing!

Now if they would just release that kit:evil2

This setup would add about 20-25 HP max.....some of the stuff (the Iridium plugs and 3.91 diff) add -0- HP, air boxes can lead to less HP, pulleys and exhaust are small gains. Plus, there are many that think the ECU upgrade is just smoke and mirrors - 2 of the best tuners can get no more than 5 HP out of ECU work. I would not consider these to be anymore than modest - FI is serious power, but just not in the cards right now for the S54.

yea man... irridium spark plugs... itll really boost your power, lmfao, get a grounding kit too HAHA. then youll be ready to put on your electric supercharger coupled with that stupid airfoil you put in your intake tube. One word... power

Steve Dinan is working on a supercharger for the M3. When he was in the Seattle area last summer he mentioned that pulleys were a dangerous mod and there was little to be gained from custom headers other than lightening up your bank account. He had a beautiful set with him for the M5, which would cost several thousand $, if he brought them to market. IMHO the 3.91 differential would be the most significant performance increase.

I agree with you that the diff swap would be the best bang for the buck on the 0-60 performance (and who needs more top end on the car?). The Steve Dinan quote is a bit off....he is referring to crank pulleys, which do remove one of the harmonic balancers from the engine crankshaft. You could do that if you don't want to ever do a light flywheel, but some (including Dinan) don't want you to even do that. All of the pulleys for the S54 (UUC, Rogue and Evosport) are accessory pulleys - they won't affect the longevity of the engine, as you are not removing the vibration dampener on the crank.

lol guyz go E-Z on me!!!

i know the plugs wont" make the deference" but i am just shooting whatever possible to improve the car by even a minimum!

as for the 3.91, u r correct , it wont give any HP but the car will have a better 0-60 and 1/4 mile times.

anyways, i wont put an AC kit nor a turbo in my car cuz its to dammn expensive and coplicated and risky, and if wanted this much of power i will buy a supra again and modify it to kill any BMW and most of the cars with much less $$$$$$$$

then again, thats just my opinion
PS: dont start with me on the QUALITY of drive and all and start comparing the supra and the M3

Evosport showed a 314 SAE rwhp dyno with pulleys, SS headers, pipes, Eisenmann exhaust, cams, custom airbox and software. They were supposed to show it at SEMA tho.

Dougkm posted dynos of Euro headers/cats, Eisenmann exhaust & pulleys giving 302 rwhp SAE corrected but on 94 octane.

Ground-Control has a prototype airbox w/ the gizmo with custom software giving 18 rwhp posted on RF recently.

There have been 3 independent dynos posted of the Superchips software (Eurobahn) alone yielding 12.7-16 hp.

Edit- forgot to add that by the time FI is ready for the S54, the E90 M3/M4 will be out (06 or 07). With a V8 to start with, why bother with FI on the stressed 6 cyl?

His comment was in response to someone in the back of the room and I wasn't paying that close attention, since pulleys aren't on my radar screen. :)

You guys should read "maximum boost" Then you realize that the major stresses in the engine come from the rotation, not the boost pressure. Drop the redline by 300rpm if need be. I have a turboed E36 that runs 9psi on crappy AZ 91 octane. It is a 10.5:1 motor. With the right tuning, the E46 M3 should be able to add 35% or more easily and safely. That means 450HP. Dinan knows this.

there are quite a few kits in out there on test cars

none that can be purschased aside from RMS and G Power.

- G Power is extremely high priced and offers no installation in US. Installation must be done by them to be under warranty.

-AA has a kit done. Last I heard they are just tuning the software. Should be ready soon.

-ESS has had about 3 different ETA dates...so who knows when that will debut, if/when they decide to sell it.

-Dinan is developing a kit. exteremly high priced and similar in performance that can be had with NA mods.

Within the next year or two there will be quite a few E46 M3 running SC's. Its too early in the game to completely rule them out
