New Mopar E-torque system

[Bad B-rad]

I was reading the question about an electric power steering being installed on our vintage iron. It made me think, about the E-Torque systems used on the new Mopar products.

All I know about this system is part of it mounts similar to an alternator, and provides extra power to the engine, during certain situations.

How does this work, and could it (economically) be retrofitted to work on our cars, or is there some huge hurdle to overcome, like an electric motor integrated into the transmission?
I think it is just a generator/ motor with a belt to add 135FTlbs of torque to the engine.

I am just curious, I currently have no intentions of trying to make it happen, just shop talk.

Pretty complex system that uses a lot of computing power to control the stop/start and is heavily integrated with the TF8 transmission. I guess it works extremely well after some initial bugs/teething problems. Probably not something for a retrofit unless you get the transmission and all the sensors/computers/battery. It uses a belt that goes around the crank pulley iirc. Maybe someone can just utilize a motor without the generator and some straightforward controls to make it happen. Probably cheaper to add some aftermarket blown induction. Maybe you can pioneer a cheap bulletproof system for the rest of us?

I cant find the article now but I recall someone doing this using the 1st gen GM hybrid assist motor off of a Tahoe. Its uses similar concept as e torque. an electric motor connected to the crank to add additional torque.

So this is how I am understanding it from what was said above.
The part of the system that bolts to the front of the engine, (similar to any belt driven accessory) is the motor, that part supplies the torque to the Gas engine, via a belt
And the part in the transmission is the generator? That is what supplies the vehicle power, charges the battery, and e-torque (suitcase) battery?

It is hard to believe 130FT lbs of torque could be added to the crank of a engine, via a belt, and work in conjunction with the gas engine.
I believe it works, I just like to learn more about it,
Imagen if you could add 100 ft lbs of torque to your Big block, by just adding a (heavy) battery pack, and a belt driven motor? Sounds cool.


The only issue with adding a belt driven super charger,(for me) is the cost of the unit, at least $3K. Then the carb or EFI. And the CR cant be to high and so on.

IF a bolt on e torque system COULD work well, it seems like it would help ANY engine, regardless of compression, cam, exhaust, and so on.

I am just talking shop, I know nothing about these system, and I am not an E TORQUE enthusiast/ advocate, I just like to learn, and I like power.

Here's a more detailed explanation of how the system works:

Our 2013 JGC is electric over hydraulic. I love it. Works really well.

Thanks Photon440, that makes MUCH more sense to me.
It provided the Torque at idle to 1550rpm.
I was wondering how the hell a belt driven motor would be able to add torque when the engine is spinning at 3500-6000rpm.
