Electric Supercharger
Posted: Fri Nov 27, 2015 8:42 am
Has anyone looked into this?
The scope of use is limited to instant power at WOT and you can't do that continuously. So probably only suitable for track cars since we can't go WOT more than 30 secs or so. Many GT86 owners have fitted it on their cars and they're seeing about 40 whp increase (dyno proven).
I think Valeo is going mainstrem with this with Volvo, and Kia is also going to use this technology.
Universal kits here are sold for about $1.8K. Not cheap but not bad either, almost plug and play. If you can get 40 whp with no intercooling, piping, expensive accessories, that is a good deal! Although you need to tune your maps.
I'm thinking of getting a rotrex. Although it only cost $2.5K for the basic kit, with all the other custom stuff, $5K is more realistic.
For a race car when all you need is a short burst of power, then the current generation of electricc supercharger is a possible alternative. Some of these kits are still using gel batteries. Lighter than lead acid, but still heavy!
Won't be long before these kits will come with 56V Li-On batteries, super big brushless motors, and we can see real big boost with these babies.Run out of batteries? Just pop a spare Li-On cell from your home charger. Heck even my lawn mower is a 40V cordless Li-On unit. Some leaf blowers are 56V Li-On.
It may take a few more years before these ESCs fully replace mechanical units, but as battery \ and motor technolgy improve, they will surely do it.
