Active Autowerks Rotrex Supercharger

[Johnny C]

I am interested to know if anybody has installed the AA Supercharger in their 95 thru 99 M3? I have a 98 M3 Cpe with 54000 Miles and in Excellent condition. I am considering going with the AA unit, but I want to know what other people's experiences have been. Is it reliable and what have you had to give up, if anything at all for the huge increase in power?

No one on here has one. What I've read on other sites is it's really good for the price. I was dead set on buying the AA one myself but I contacted DA-MOTORSPORT.com and have been working a deal with them on getting a turbo instead of supercharger. I'd go to their website and check it out. Here is the e-mail that I got from them:

"Hallo James,

For the E36 3.25i we offer a turbocharger system.

Turbocharger kit makes 300 hp at 7 psi of boost pressure.

The info about this kit will be soon on our webpage.

Price will be 5000 USD for the turbocharger kit.

In addition to the turbo system, we offer a supercharger kit that makes 260 hp and is for 6000 USD.

We highly advise the DA Motorsport turbocharger kit.

Have you seen the Z4 turbocharger kit? E36 turbo kit is very similar to this one.

Best regards

Mert DASTAN "

A 5000 Turbo is cheap and I've seen their videos and their cars are amazing! So I'm temped to go with them. Note, this is on a 325i that's making over 300whp.

I plan to possibly put the AA supercharger on my E36 M3 this summer. I will keep you posted when I do.

I have an AA turbo system on my 99 M3. The engineering of the system is great. The customer support Active has is incredible. I don't know much about their SC system, as a company though I can't say enough.

[FREDPLT]

I have a 98 M3, why did you go with the turbo over the supercharger, seems like the Supercharger produces more bang for the buck. What are your thoughts on this?

[spieluhr]

choice between turbo and super matters mainly on people's preferences for how and when they want their power, and what suits their car the most. I would search the e36 forum for info on Forced Induction cause there have to have been a hundred topics on this subject.

For a brief synopsis in case you don't know the difference, a super charger runs off of the pulley system of the engine. Therefore right when the engine is fired up the supercharger gets spooled up right away and is able to give you immediate power from the low end of the RPM range. Turbo chargers are placed in the exhaust system and get spooled up by an increase in exhaust pressure. The problem with this is that it takes a while for the pressure to be great enough for the boost to kick in, hence the term 'turbo-lag'. Turbo's tend to kick in more towards the higher end of the RPM band, however this is also dependent on the size of the turbo, smaller turbos provide less power and spool up quick, and vice versa for larger turbos.

so all in all, super chargers can provide you immediate power from the start, but suffer in the higher RPM range. and turbos excel in the higher RPM range and have more potential for power, but lag in the lower RPM range due to having to spool up.

hope it helped, and don't forget to search

Yes I realized the difference, I was just thinking that the Supercharger will give more power over the entire spectrum, and no turbo lag. I like to drive fast, but mostly in the corners. I just thought a supercharger would be the best to boost the power and give me power no matter when I wanted it. Does it tend to loose pawer at high RPMs?

an SC will not "really" lose power in the higher RPMs. what happens is once the SC has hit it's top band it no longer produces power. This happens in the upper most RPMs. the basis on when that happens is dependant on the psi pulley. most SCs come with an 8 psi pulley but you can have a machine shop weld on a 12lb. pulley and get more out of the SC. I had a 3000GT with SC and twin turbo with a 12lb pulley on the SC. that allowed the SC to produce 500hp. For what you are asking your M to do you can do just as well with the SC and an M50 manifold for your top RPM power. you won't get as much power out of the SC but you will have power through your whole band with no lag. so in short, if you want the power through the corner when you accelerate i would say stick with the SC so you don't have to worry bout spooling up.

Cool, thanks for the Info, time to save for the SC! I am pretty sure it will be worth the wait!

I totally agree that you will enjoy an SC. I am looking for the same type of performance as you. i am not concerned with a bunch of power i will be just as happy with performance from the line through corners and the SC with the M50 mani will do that. I also suggest what others have suggested and get the euro HFM for more airflow. :-)

I have a friend who has AAs turbo kit on his 318TI with a 95 M3 motor with a complete motor rebuild putting out somewhere around 425RWHP. His car is pretty sick! I plan to go with their SC Stage II when it is released for every day driveability.

Yeah i won't deny that a turbo putting out that much hp is wicked! i just don't need all that power to race with. Hell i can't get anyone to race me in my M while it is stock. I have gotten plenty of looks from all the others but they won't step up. so the SC will be just fine for instant power and relliability. much less to have to worry bout going wrong LOL

I've seen many posts looking for E36 Active Supercharger gains. I have a 98 M3 with 50,000 miles, with a stage 2 AA SC kit on order which will be installed before Halloween. I have never put the car on a dyno, which sucks as I've done every modification apart from the bottom end (pistons, crank, tranny, rear end stock). I can't do a stock vs post blower, but will get the car on the dyno before the blower goes on. They are rating this as 420 HP on a "stock M3," so I should be close to 500 HP with what I've done already.
