Electric Supercharger Boosts Torque by 50%

wonder if this is the same technology that E-ram or ADM supercharger has been harping on all this while

 

worth a read though

Currently vw mers got these in their small engine. But I think not electrically supercharger, instead driven from the engine which sucks power.

Electrical supercharger would be great. But in a car you want 100% power all the time. When the battery is low, there may not be supercharged power, instead only the puny 1.2l engine power. It might not be a problem in Singapore, but will be issues in the states/Europe superhighway.

Based on the spec, 1.5A at idle is still ok, but 220A at steady stead (assumed cruising). The battery will be dead real soon. If a car is designed ground up with this tech in mind, they electrical consumption will be taken into consideration.

 

But if this is offered as a drop-in kind of mod, it will not be as simple as dumping this in at the air-intake. The car charging system will have to be upgraded to provide enough juice to run the supercharger as well as supplying power to the air-con, lights, ICE, etc. The rectifying circuit must also be able to handle the huge amounts of output from the alternator when the supercharger is running and when it is not. And these are just the most basic considerations.

 

We haven't even take into consideration what the supercharger needs when the car is in the acceleration phase.

sounds too good to be true????

[Joseph22]

This one legal to use in singapore or not? if illegal or need to send car for testing, the money will not be worth it liao. unless intended for underground mod...

An electric SC will not produce enough boost. If it produces enough boost to make a difference, you'll need to tune the engine like a normal SC or TC.

 

For this case, maybe it'll help in the low end. But would need to tune nonetheless.

there is no replacement for displacement. Think it's still quite true for now and unlikely to change in the next 10 years. Give these stuffs another 10-20 years to evolve, let others try out first, let the smart Alec who invent these to improve further. Meantime, just get a ride that you like (not what others perceive), keep the engine stock and enjoy the fun.

 

Too many people still complaint about engine under-power nowadays even with DVVT, VVTi, VTec,........................... multi-valve, DOHC, all the numbo-jumbos. What they've forgotten is, they have to rev the engine hard to bring out the beast.

 

Your engine won't crack even if you change gear at 4~5K rpm and it's usually at 3K and above that the engine starts to wake up.

interestingly, the engineers at CPT claim that the SC is to work with existing car infrastructures and they plan on going OEM with these kits

taken off another site, seems that claim the SC performs better than the turbo? :P

You need 220A of battery juice to power this thing.

For a normal car, where can you find this juice?

It comes from the alternator, which in turns sucks power back from the engine.

 

It's the same thing for those so-call "electric charger".

To make a PC fan works, someone calculated that you need 48 pcs of pc fans.

 

The bottomline is, the input energy used is too much for the output.

 

In terms of efficiency for the whole system, it's probably negative.

Does it help if we use cyclone or simotu ventilator?

 

They claim that the air will swirl and result in a better mixing of fuel/air which will give a more complete combustion.

 

Any bros here have experience to share?

 

I recently installed the ventilator and feel car got improved pick up and FC seems to be better.

But I cannot confirm wether it was just the mind or it was real

 

Anyone did some scientific way of proving?

Yea agree, for most of the bread & butter cars, most of the torque will be available from 3 to 4.5K RPM

Average car alternator designated as high output usually rates at less than 200A(based on web search). The product spec which they put rates the item as 220A at cruising. I don't think the alternator output will be sufficient to drive this supercharger and all other items in the car.

 

Maybe they just put in the supercharger and did a dyno without long term real world test, or maybe they have upgraded their charging system without mentioning it in the report, or maybe something else which i do not know.

 

anyway i believe the concept is good as long as it is well integrated into the current systems.

Their motor spec used is a bit low.

 

I am using a big ass motor for my r/c application and can do up to 5kw/6.7bhp of power. I used it to push my 10kg boat 90km/h.

 

If they consider using better motors, this might work. The motors are getting better and better, mine is not the highest spec. There are even higher ones that does 10kw/13.4bhp motors.

 

Attached the size of my motor used for r/c purpose.

 

[Zuoom]

electric supercharger would work, provided it's around this sort of scale.

but with a big ass motor, you will need more juice aka batteries.

For bolt-ons , we have to recognise the limitations

- % gain in the engine output as it really depends a lot on the intake, exchaust, and control. any bottleneck in between is the limitation.

- cost of running the system : addtional weight, maintenance issues

 

in my limitted experience, the cost of the add ons far outweight its gain.

Improper installation or overloading on electrical stuff will cause FIRE. How many professional electrical automech in SG? You have been warned here.
