Check out BoostHead.com they have a Electric supercharger that is actually working well. I have been discussing with them the possibilities of a unit for V8 that could push 10-15 psi, he currently is prototyping a 5 psi unit for 5.7 truck. I am wondering who all would have interest in something like this?

 

Wow, strap 3 starter motors to a screw blower and your in business! Looks pretty neat! Maybe a twin setup for us?

 

Well I was excited until I read about it. 15 seconds of power then recharging doesn't sound to exciting, sure it seems cheap to just plug into your outlet, but after doing this a few times a week still adds up, so how much cheaper could it really be than nitrous. Also nitrous is still cheaper for a kit which means your still spending more in the long run on this system. Plus you must buy at least 4 batteries for a 4 cylinder engine, which takes up plenty of room, not to mention again more money This places sells them for 70 some bucks http://www.batteryweb.com/odyssey.cfm I think I'll wait until those high capacitors come out. If the kit was even 1000 dollars it would be more tempting but 2000 plus batteries, Ill just go with a regular charger instead and do it the right way.

 

It looks like there is somethign in the circuitry that limits it to 15 secs, perhaps to prevent the batteries from overheating? I thought I read that you can get several pulls out of the battery pack, and that the alternator can be used to recharge the pack. I would imagine that some sort of charging controller would have to be used to limit the charging current to prevent a huge load on the Alternator. You have to admit this thing looks much better than those things going on Ebay! 15 secs should be more than enough to get us down the quartermile!

Where's all the STS boys, here is something truely INNOVATIVE

interesting but pretty much useless to us...max engine size is 2.5L in any case.

As said above, I wouldn't pay $2k for it either way...

 

well there working on the V8 stuff. They are going to be utilizing capacitors for most of it not batteries, so if they can get the technology together then it would be a worthwile setup. Plus all that extra weight can be put in the back where we need it!

 

Phil,
It wont be long 'till we have a larger setup, but for now some points:
No, at 75 hp the system would have to weigh 1000 lb to make it a 'wash'. The ESC weighs 38lb (less than the Lightning Eaton by itself), and the batteries, cables, solenoids, etc will be an additional 70-150lb. The use of four Yellow Top and everything would add 200lb total, requiring about 15ft/lb to be a wash. The 8lb per hp we used to use was for 2000lb chassis cars. If you have a 3000 lb car with 300hp, and you get a 5 psi 75hp increase and the car weighs 3200, you have gone from a 10:1 down to a 8.53:1 ratio (about .7 to 1.0 seconds faster on a 13 sec car) Add to that the fact that the 75 hp gain is almost completely across the rpm curve, where at times you are adding 50-75% more power. On a 105 wheel hp 4-cyl we added headers and 8 psi and doubled the hp to 208, with the curve showing a 120% gain at low rpm in certain areas.

 

So I may be dumb, but from what I read you gain 75 HP but add 1000 lbs to your car. I dont think so. it seems like everyone is trying to reinvent the wheel these days. This will never take off unless he can make it more compact and not weigh a ton. I would actually like to see some time slips with this thing installed to see before and after.

nah the system only weighs like 100-200lbs...he was saying to offset the amount of power it makes it would need to weigh 1000lbs so thats not an issue

 

The other cool thing is that he is working on a unit for more than 5psi, which would add the power like a turbo and still only wiegh 150lbs. Right now this is a work in progress, but for smaller engines it is kicking but.

I want to let him know what kind of interest the F-Body crowd would have and what kind of power and boost they would really want so I can get him to start working on some real stuff and leave the rice alone!

 

No doubt innovative, i like
Electric is where alot of new ideas are heading. Great idea, just a matter of time until the battery technology/alternative power comes into play. The electric motor power/presision is here just $$$$$.

 

Yeah, just think what could be done with brushless motors and high caps. Since this is mostly capacitor work anyway.

 

So how far away is the technology? I really love this type blower, as a matter of fact the lysolm screw type would even be better cause they pump out more power and look like they would fit even better in our engine bay http://www.kennebell.net/supercharge...60/gm48-60.htm
Having off the line boost does sound appealing for tire shreding fun

 

The twin screw would be sweet. We could see more boost with the same electric motor setup.

 

what about nuclear power??? JAJAJ
