Electric Turbo - Torq Amp

[kinger]

These are so intriguing!

They are on the small side now and make about 6 psi total on small engines but I am loving the development.  The 'power box' could be mounted in the truck for weight dist, no oil lines, the turbos weigh 14lbs each so super light. 

Compounding or doubling them up helps deliver more air.  $2500 ea right now. 

Needs more time but this will be awesome when my girls start modifying their cars LOL ( they are 10 and 7 now).

Lol so the Torqamp things are a little on the cheesy side, but I think do work. Cleetus and James did a few videos about them lol.



Here is what you really should be looking for.  I've been to the BorgWarner turbo factory in the Carolinas and got to see some of this stuff.  They had a Cayman with an electric turbo on it that could run 20psi in 6th gear at highway speeds part throttle.  They said it was like driving a car with an NA big block.  It was raining or I might've been able to take it out

Electric turbo… reminds me of an e-bike. Yeah, they work but do you really want to be seen on one by your fellow enthusiasts?

That looks awesome!  The E booster and larger turbo combo sounds fun! 

LOL wicked!  If it goes I am interested, I don't care lol

Neat sure but the whole point of a turbo is the efficiency of using the wasted heat energy from the exhaust. An electric turbo is really a supercharger.

It's Audi doing something like this?

I actually tried an electric supercharger out on my BRZ several years ago.

It was surprisingly effective, though a little clunky. The control was basically on/off back then, so you set the little switch up to only kick on at full throttle. Very noticeable, though modest, increase in power. That's all I thought I wanted in that car but it just kept escalating as those things often do.

The e-booster is a supercharger style it forces compressed air into the engine and turns off after the turbo spools.  Forcing more air into the engine creates more exhaust which causes the turbo to spool.  It is actually very similar to the sequential twin turbo systems where one is just there to support the other.  The mustang they did is pretty sweet because they could upsize the turbo making a ton more power while still having a faster low end response than the factory turbo. They nearly got to NA levels of throttle response.

It is an electrically driven compressor, but I guess you could argue since it is working in parallel with a larger turbo charger, and the intent is to improve performance of the turbo, it is a part of the turbo charging system.

They're also doing electric turbos that have electric motor integrated in the turbine shaft and turbo housing. It can stop the turbine to regenerate energy to charge batteries, and the motor spools the turbine extremely fast.  They're being developed extensively for over the road trucks. Big efficiency improvements. Basically the same tech being used by F1.  It is recapturing thermal energy from the engine when you're off throttle which still with a turbo is wasted.

If I was bored and had room for another project. Sure why not

A turbo is a subpar platform to do this with. Ya stick a cheap china geared blower on there with a mean brushless RC motor and a decent lipo battery pack.

 Then you can get some actual decent performance out of it. A youtuber has done this. He also describes how to build what he did for about half what his cost. Impressive numbers and decent 1.4 times IMO. I think he averages about 6-9psi on SBF setup with boost falling at higher RPM. It would make some serious boost on a small cube motor.   

Electric motors are coming whether we like it or not. Might as well get use to them and start with something small!  I build electric pit bikes that stomp the hell out of the modded gas bikes. Its not even a competition most of the time. Pretty fun newish tech anyway.
