Supercharging my BMW E46 328i

Putting a Rotrex Supercharger with intercooler on my BMW E46 328i
This is a car I use for drifting and practice on events, both summer and winter.

[@cdeprima1209]

Power steering not required on those cars, I heard intercooler not really needed either; just helping to make those upgrade easier and cheaper! cheers! :)

[@mariuslaspaas]

I would not go drifting without powersteering pump. Yes IC is not required. But it's preferred to have it. The IAT gets hot on track.

snyggt bygge! ladda gärna upp mer när du kör med den

[@mariuslaspaas]

Takk. Ska forsøka ladda upp från vinter och sommer körning :)

Hello, could you send me photos of how you connected the compressor to the throttle and where you have the flow meter. Regards

[@mariuslaspaas]

It's out from compressor. Through intercooler and then up into the throttle. The flow meter i have in front where the headlight is.

Donde puedo conseguirlo

[@laylowlayslow7283]

Where'd you get the bracket for the supercharger?

[@mariuslaspaas]

It's from this place www.schaper-automotive.com/en/

[@andreioctavian4594]

What size is the serpentine belt, or maybe you have a part no, thanks.

[@mariuslaspaas]

You need to adjust this out from what type of idle wheel you are running on the charger

[@ruffraff4697]

Hello what compressor is it? Rotrex model?

[@mariuslaspaas]

It's a c30 94. A bit older charger.

[@thefelix1100]

why did you went with supercharger and not turbo? Thinking about the same for my drift practice car

[@mariuslaspaas]

Well. I did it because I found it easier. Also if you watch my other videos I have a project with turbo and more power in my volvo940. So it made me want to try supercharger on this one 😊

[@acef_performance8416]

I've had my supercharger for a few years now and reliability is great

[@mariuslaspaas]

@@acef_performance8416 What boost your running? HP? Stock engine?

[@g.g4816]

kompresor is more natural

[@mariuslaspaas]

Yes

[@havrancsikgabor8082]

how was the ecu program written?

[@mariuslaspaas]

It's made by fekzen.se in sweden

[@winha1435]

What injector model and parts you used? I have rotrex at shel waiting to install but stock injectors cap bretty soon and afm only read 750kg/h so around 270hp befor it goes over the map?

[@mariuslaspaas]

I have upgrade injectors. But only to 440cc I think it was. I know I mentioned it in the video

[@winha1435]

@@mariuslaspaas You did but bag says siemens s-400 and you talked about bosch. I was intrested the model they are if they are straight blug in so i can do price comparison.

[@mariuslaspaas]

@@winha1435 yes. Sorry I didn't realise I said Bosch intill now. The injectors are Siemens. But the plug is Bosch. They are direct swap. Siemens nr 9470199

[@winha1435]

@@mariuslaspaas these are really nicely priced, i just find hard source injector dead times and spesific data for these.

[@mariuslaspaas]

@@winha1435 yes. I know. Not much data on them. Maybe because they are used oem on volvo and saab i think.

[@kayra4840]

From what car do you use super charger?

[@mariuslaspaas]

It's a Rotrex supercharger. It's not taken from a car, but it's possible to buy a kit for different cars. 😊

[@acef_performance8416]

Mine car is using a Vf engineering supercharger

[@mariuslaspaas]

@@acef_performance8416 What engine You're running?

[@freshchicken9354]

How many HP does it make?

[@mariuslaspaas]

Haven't dynoed it yet. Maybe about 250? I will add some more boost and have it on a dyno before the summer.
