    Audi SQ7 4.0 TDI - electric supercharger.

    Hey. Digging up old thread. I found link to a video where some people actually managed to get this turbo started by spoofing CANBUS messages: This project is documenting progress here: https://forum.driving-fun.com/viewtopic.php?t=13280&start=400 but no information about canbus frames. I...

    How much can I "overpower" my brushless motor?

    When pushing for limit, please remeber about wires and connectors. Maybe motor will not run hot with water jacket cooling but other pieces might not like it. I don't know what are Your wire gauges for motor and ESC but just don't forget: For every system when components have different limits of...

    Audi SQ7 4.0 TDI - electric supercharger.

    When I originally was planning on using this supercharger I was thinking about converting it to BLDC construction. For price of less than $200 You could basically scrap everything except case and compressor wheel and put TP Power motor inside with BLDC controller

    On the disassembly video they say that propeller axis isn't magnetized. That is why I assume that BLDC controller will not work in this case. I think this construction is called reluctance motor and controllers for those are quite expensive and not so readily available.

    Audi SQ7 4.0 TDI - electric supercharger.

    Back to topic: I have read some comments under disassebmly video but I also found one more polish Youtuber that tries to make this supercharger work. First one claims in comment that they managed to get it running but only in on/off mode (for me this is already win because I don't expect it to...

    Is TorqueAmp financially comparable to DIY?

    This bill of materials is work in progress PCE157.1002 P-2 Centrifugal Supercharger Polished Head Unit $625 16x Venom Fly 50C 3S 2200mAh 11.1V LiPo Battery with UNI 2.0 Plug (XT60/Deans/EC3) - Compare to E-flite EFLB22003S50 (Or maybe readily available 48v EBike battery + charger for...

    Here is the supercharger I would start with...

    For me it says that it's currently unavailable but I guess it has to be related to location of Europe. I have to say that in pictures it looks very promising in terms of converting it to electric one.

    What should newbies know?

    Methanol is a good point because it cools down the engine, and probably most of the electric turbo setups will not have intercooler. Methanol injection will help with engine efficiency and operating temperature a lot, especially on hot days/climate.

    Is TorqueAmp financially comparable to DIY?

    Hey. As first topic in TorqueAmp SubForum I wanted to touch topic of financial argument against/for TorqueAmp. Currently I can see it's cost is 2272 Euro or about 2700 USD on official website. Let's compare that with some DIY solutions but let's try to make it apples to apples comparision with...

    What should newbies know?

    One of more important aspects that should be considered is tuning the ECU. If You are converting naturally aspirated engine to a turbo one You need to tune the ECU. I'm not aware of ECUs that would be flexible enough to allow for boost without retuning. So basically for many cars it's a big...

    Audi SQ7 4.0 TDI - electric supercharger.

    Problem with connecting multiple is problem with how to do it optimally. Do You connect them in parallel or do You connect them in series? Price currently is quite good but I think it will go up once people know how to control them and everyone will want one in their car. I'm glad to hear that...

    Audi SQ7 4.0 TDI - electric supercharger.

    I'm very interested in Audi's electric supercharger mounted in Audi SQ7 with 4.0 TDI engine. They are quite cheap for used one and can be bought for around 600-1400 PLN ($150-$350) in Poland or about double that new one. It's produced by Valeo and it runs on 48V system, I think that part number...
