Hey guys!
I haven't been here in a while but felt like I should post here since the DSM crowd is by far the best community I've been a part of. That being said, Ever since I sold my 90 GSX and moved to Ohio; I've been working on something that's been worked on before but abandoned. The Electric Supercharger/Turbocharger. In a nutshell I found a motor that will spin at 40,000 RPM'S and built a speed increasing gearing system that is 1:4 for a total of 160,000 theoretical RPM'S.
Without giving out too much details on the system until It's ready to be released, I've effectively removed the exhaust housing from the turbo and replaced the exhaust turbine shaft with a geared shaft.
After a couple of tests, I can verify that this system is producing 15 PSI in less than a quarter a second. I was able to get these readings by attaching a leak tester at the end of the turbo and fired up the motor (Yes I'm aware the long pipes could affect the time to build boost).
I will also be posting pictures of the set up once I print out a proper case for the motor/gearbox so stay tuned.
To further explain the system I have now, the motor is currently being powered by 4 LiPo batteries (2 series + 2 parallel) and controlled by an ESC that is controlled by an Arduino Leonardo board. When the car starts up, the compressor wheel spins at 30,000 RPM's and will increase the speed to 160k theoretical RPM'S only when full throttle occurs (reading TPS voltage).
The turbo set up will have to be a compound set-up as this is for small-large turbo applications. In a nutshell, the small turbo outlet is feeding the big turbo inlet and the filter will be at the small turbo inlet. The reason for this is because the larger the turbo the more "power" is required to spin and maintain boost which is why I'm only planning to create an electric turbo out of the 14g (possibly smaller).
That being said, I am not an expert. I am just a guy with a full time job and an idea that is apparently working so I have a couple of questions for you guys.
I know I need to set up some sort of oiling system for my custom gearbox. Does oil need to be pumped (I'd assume so with the smaller gear spinning at 150k RPM)? or is there a way I can place the gears so they will move oil on their own (2 gear system). Now that the turbo is no longer attached to the exhaust housing, will the turbo still need to be fed oil? or can I close the oil feed lines with oil already in the turbo. Would this be something the DSM community be interested in if I can create a polished tested product? and more importantly, Are there tuners interesting in testing this electric turbo? I say tuners because that massive bump in PSI in the low RPM's range will require fine tuning.
what do you guys think?
