What supercharger can I get to get between 400 - 500 whp? I know that there are is Dinan, AA, ERT etc. What setup would be the best for a '98 M3? How much would I be looking at if I wanted to achieve such power in the M? I doubt I want to get a turbocharger and would rather have a flat torque line throughout the rpm range. Let me know. Thanks. :az:

if you're looking for that high of power, the only kit I know of is RMS Stage 2 or Stage 3. Dinan is only at ~290whp, same or close to that for AA.

Remember that the higher the hp, the less reliable in the long run.

I don't know of any supercharged M3s that are running 400-500rwhp. That's insane. I think ASA is probably the best company out there for producing the most HP. I don't know what their site is, but I'm sure you can do a search and find this...

Like Mitch said, reliability isn't going to be that great when you're pushing that much power, it doesn't matter how much tuning you have done to the car.

You should also do some research before jumping the gun, blowers put massive stress on the engine, so you have to make sure and upgrade every part of your engine to ensure proper functioning and so that nothing breaks in your engine...

ASA is limited to approx 8.5psi from what I've seen. That will put it at around 300-310whp I believe.

The Vortech's will be your best bet as far as pushing more boost. As far as reliability is concerned, I'd rate the kits in the following order from what I've seen: Dinan, RMS, and AA (still a newcomer but I'm sure they will be rock solid due to their reputation). I wouldn't put an ERT kit on my car (just my opinion).

True, but 8.5 psi from a supercharger is plenty and putting down over 300rw is a lot of power for our cars.

Personally, as much as I love turbo cars and blown cars, I wouldn't do either to the M3. That's just me though...

I shouldn't say a lot of power, more like, it's plenty of power:)

Okay.. What if you strengthened the internals of the engine? What then would be the point of failure?

I've been thinking about this a lot lately and decided to go SC. It's the most reliable from what i've been learning.

So, say I strenghten the internals and then slap a blower on it, how much more reliable would that be? Could you realistically up the boost by using a smaller pulley, etc?

The AA setup seems pretty solid from all accounts so far. The Dinan setup seems to be the most reliable one out there now. This is the frontrunner right now, Dinan.

My car is CPO so i'm investigating what going the Dinan route will do. I would like to still have it warranted, but I'm prepared to move ahead if it's not.

What are your thoughts on this?

If your heart is set on s/c and not turbo for that kind of power, you're looking at a Stage 3 set up from RMS at least.

Phil has an S52 Roadster, Stage 3, and is somewhere around 385-400 rwhp...

If you are talking about an E36, then RMS is the only way to go for max power. The keys to working with them are patience and living locaaly to their shop. Takes them a bit to get each car perfectly tuned, but one they are lookout. They produce the fastest E36's on the planet

oh great Jeff, you better stick around this thread til the end. I can see this one getting out of hand!!:rolleyes:

Tuning will be your biggest concern at that power level.

Check out www.siastuning.com

They've got a 400rwhp S/C'd M3 on there basically running full exhaust, RMS Stg 2 (started as dinan stg.1 i believe) and a TEC3 system.

Jeff, that's a pretty funny comment but I would respectfully disagree. Call Turner and talk to Dave in service about what chip made 27whp more on an RMS stage 1 setup (a car with a fresh motor 'courtesy' of Osh's previous programming) than it did with a chip from Osh. BTW the owner didn't swap programming to get more power, he changed to get a car that would run safely, and not much another motor.

Thanks for all the info.. I have decided to keep my M stock and just work the suspension later after I get lots of practice and learn how to drive it really well. Ill do simple upgrades intake, chip, exhaust. I am going to take some extra money and get the new Yamaha R6.. And just play around with that.. Thats true speed! on a beer budget! (maybe a used one with a Yoshimura exhaust system and chrome rims.. The blue colored one) maybe later put a little turbo on the bike.. That will be fun! :evil2

Well, I agree with this statement. I think RMS does provide the most SCed power for E36 in the States. However, you need patience greater that China's Buda which really shouldn't be the case since you are a paying customer after all.

Wow, I thank everyone for their emails. Hard to think things changed so much in just a few months. I hope that it all gets worked out soon for everybody. Tuning is the hardest part of building these cars as you all know. The stage 3 cars that were tuned at RMS including my own were just plane insane so thats what I base my statement on.

Sean, you are related to Buda I guess :(

Thanks to everyone for your interest in Eurobahn. Things are going real well here I have found a great NA and stock FI software programming system which I will be representing and am working on some very cool other hardware that I will let you guys know as it comes together.

I'm DEFINITELY not going with RMS!

I haven't seen or heard anything good about them and I've been researching this for about a year now.

I don't know M3sleeper, a motorcycle around DC/VA/MD area? I think that's asking for trouble (not saying you will not be a good driver); but, I'm speaking that you might get hurt BECAUSE of the driver's around here ... they sure as hell don't care if you have a car when they cut you off....

Right.
