Has anyone thought of adding this electric centri supercharger to a big turbo setup to help low end and spoolup?

I thought about using one of these as the filter on my turbo!

 

Baller on a budget.

 

This electric Thupercharger:




..will probably make a 1.8 spool that GT3076 like a 2.2L

 

I have a better solution

 

I came out of lurking to lol

 

 

How about a 2-stroke supercharger?

 

These guys are nuts! This is a great review of the capabilities of these electric supercharges.

Fixed!

 

How about a jet engine made out of a turbo feeding the exhaust gasses for another turbo that's blowing into the engine?

 

Thats pretty much what they are already doing in WRC, except not using another turbo. They just put a flame tube combustor in the manigfold before the turbo and use the turbo like a turbojet. It can just steady run, and then when they need boost the turbo is already at full speed, even at low RPM.







Ive already decided Im going to build one of these one day, probably on a Honda.

 

You definitely fucked that up...

 

There is a huge difference between those electric superchargers, and this electric supercharger:


Thanks to the RC modeling hobby, brushless motors and controllers have become cheap and their performance is nothing short of amazing. Lets put it this way, all of the fastest RC planes and helis are electric.
Slap a compressor wheel and housing off of a real turbo on the shaft of a big *** brushless motor and you get an electric supercharger that actually does something.

I would think you could use one of these as a spool aid pretty easily. The hard part would be making some kind of bypass so it didnt act as a restriction once the big turbo starts blowing through it.

 

Why not put an electric motor directly on the turbo compressor wheel instead. "F1 MGU-K", ghetto style.

 

Looks interesting

Specifically? Mostly the fact that half a dozen groupings of the best motorsport engineers in the world combined with a total budget somewhere well north of a billion dollars a year hasn't made this reliable yet.

 

It will be reasonable reliable sometime and if the complexity is reduced (only spoolup and not charging) the chance is greater.

But it's not time for a electric compressor connection as a standard option (from Garret, BW etc) just yet.

 

The problem I see with it is that it either has to have some way of disengaging and allowing the turbo to free-spin, or you have to build a brushless motor that can reliably spin up to 150k+ rpm under power. If the turbo is trying to spin faster than the motor can spin it, then the motor will be acting like a brake and slowing the turbo down.

 

None of these gimmick electric superchargers work due to only being fans and not compressors. Now if you could get a descent RC brushless inrunner motor with the right KV to provide enough power and shaft speed to spin a compressor you might get something that could work. Use a bybass valve found on most crank driven superchargers and you might be able to get something that works. Running a 24v electrical system would help to get the motors spinning fast enough to spin a centrifugal compressor fast enough to make any real boost.

I need to dig through my automotive engineering book (or Google ) to find a chart to show how much HP is needed to drive a supercharger. I remember something like 30hp for 5-7 psi on a 4 banger and closer to 100HP for high HP applications. Even at 30HP that is a ton of Watts/Amps.

Add upon the cost and you can build a dig churbo or find Greedy kit for cheap!
