Electric supercharger. Topic revisited. New idea!!

[2006kmls]

The problem with electric supercharging seems to be that you can't get enough cfm from a DC driven fan/motor combination to build pressure in the engine. Anything out there that would run on DC requires TOO MUCH power to be reasonable or cost competitive when trying to get enough cfm to build pressure.

What about this:

This blower runs on 120 volts, makes 4100 cfm, and draws less than 15 amps at 120 volts a/c.

These are standard industrial blowers that you can get from a 100 sources. They are cheap ($500-$1000) and are precision blowers with tight roller bearing fan sections with SUPER TIGHT clearences and they build pressure.

What you do is add (1) extra battery in the trunk of the LS and tie the batteries together via an R/V isolator. During normal operation the LS's alternator "sees" and charges BOTH batteries, but only allows one to run the blower. You add a 200 amp alternator to the LS to make this efficient. These alternators are available for $200 (Powermaster). Then the one battery you added has a DC/AC inverter connected to it, whereas it has 120 volts coming out of the inverter. 20 amp inverters are available for less than $200 from a million sources. This 120 volts a/c then powers the blower.

You can use a switch for wide open throttle and just "turn on" the 4100cfm blower, which is fed with cold air and a filter and is plumbed into the intake tube. And you have a forced air blowerm with mega cfm.

You could also get fancy and get a TPS (throttle position sensor) to feed into an a/c frequency drive (0-5volts) and as the accelerator was depressed the a/c drive would speed up and slow down the 110v motor on the blower!

Why can't this work?

it doesn't work because the DESIGN of the unit cannot build pressure - only flow air......

take a look at the LEADER in electric supercharging - www.boosthead.com .

for a real small displacement engine - they have been able to make it work - but with a unit designed to compress the air (a real supercharger driven by electric motors) - not simply flow air (like a powerful fan).

 

[2006kmls]

These industrial blowers will build pressure. Up to 10+ PSI!

Why will it not work?

The boosthead unit is three Taiwan bulit starter motors mounted to a plate spinning a conventional turbo charger or a supercharger. Its hardly leading edge technology.

 

[Quik LS]

dude - you asked - i answered - if you don't want an answer don''t ask...

I didn't say boosthead was leading edge technology - it is technology that works.... standard supercharger that is driven form electric motors.

it's not only the strenght of the fan - it's the housing of the unit and the way it joins with the intake manifold that allows it to compress the air....

build it - that's the best way to prove it out.

This is probably your best bet: http://www.turbodyne.com -

Looks like it'd fit nicely where the airbox is. Couple of brackets, some hose work, and a few electrical connections. Doesn't say what PSI it makes, but the 24v version (Turbopac 2500) makes 5-6psi.

Says for '94 and earlier vehicles, but probably useable in conjunction with the X-Cal. I'd like to know what the price is for this thing.

Any one every heard of cold fusion (cheap CHEAP n20 rip off They use CO2 ) They have a TURBO that mount to your intake and when you "spray" it spools "just like a real TURBO!!!!" LOL I saw it a SEMA last year and It is a joke There is nothing that will replace a REAL turbo are S/C so,,, Just adding my two cents .....

 

[2001LS8Sport]

The tolerances and turbine speeds required to build repeatable boost are not possible with this set up.

Richard Holdener has tested these. Now, for those of you who don't know him, he may very well be the country's leading expert on boosted applications. He has thousands of dyno pulls with every conceivable combination you can think of. Get his book for incredible information. Anyway, when he tested these, the most hp he could ever get was 3 to 4...and it wasn't repeatable. Spend your money elsewhere.

 

[FreeFaller]

Wait...wouldn't you need to come up with 3-phase power just to get the oomph to compress anything? It just seems like single phase wouldn't cut the mustard.

 

[MrWilson]

Also figgure on that your adding more weight, and with a lower psi, like some are saying...would it realy offset that diffrence enough for it to be worth it?

if ur pulling all tat amps u should be fine but how would you create 120 v 15a in a car

 

[beaups]

120v 15a is 150amps @ 12 volts assuming no loss in the transformer. so basically you would need about 180-200 amps or so available @ 12 volts to run this thing assumming the normal 10-20% loss in the step up transformer/inverter. Which puts you in the same situation as the boosthead product. Need extra batteries on separate circuit and a method to charge them. really seems like we're reinventing the wheel here. boosthead has done all this work...solenoids, controllers, etc....

 

[Quik LS]

good news - we can build our own -> http://www.gaprojects.com/supercharger/supercharger.htm

 

[2006kmls]

Clearly this thing has no power! Its a bathroom fart fan and a dryer hose!! LOL

Why can't this work?

Considering the starting current on an AC induction motor is about 5 to 10 times the operating current, I think the little inverter will blow. In fact, most inverters that provide 110V AC from 12 or 24V DC (batteries) will say not to use with motors or inductive loads.

 

[beaups]

an inverter that drives 20amps @ 120V will draw OVER 200 amps @ 12 volts...probably closer to 250 or so considering loss. This brings to the same issue boosthead addresses...totally separate power supply, etc...and only limited run times. then you have the issues of fuel, where to feed the compressed air, controlling blowoff (bypass), etc. etc. etc.....boosthead seems to have addressed most of this so it really seems like we are all trying to reinvent the wheel here. His unit SHOULD work fine w/V6 model. I'd ask him more q's but the unit appears too small for the V8. It's an under $2K solution so why doesn't someone just pick one up and let us all know?
