probably a stupid question but are those electric superchargers any good?? i think they are probably pos. but just thought that i would ask.

z28hokie

POS...your thought is correct...

judds99t/a

yea, i just looked it up in the forced induction forum and they seem to agree p.o.s.

id think a hybrid unit that uses eletric motor to get things movin off the line wolud be benfical to ya loe say eletric for the fiorst 2500 rpms or so then let the engine pulleys take over

It's takes too many amps to push an electric blower. Leave that crap to the ricers.

So thats how they are so fast

How does an electric SC work???

z98

It doesn't.

'nuff said.

garrett made a prototype turbo charger that used a 50amp motor to "pre-spool" when exhaust valves were not enough. Not sure if it ever made it to production. Generally speaking this application would be a big huffer turbo on a small 4 banger where lag and high boost is a must to reach your goals. Say if you wanted that GT30 to spool at 3000rpm and make 400whp out of your 1.8 litre, it would be a good choice.

electric superchargers are stupid, though , you'd probably suck down any gains due to the amp load on the alternator heh.

I can tell you from certain knowledge that an Eaton M112 SC (stock 03/04 Cobra) at WOT redline is using over 70 hp to make the 8-9 psi boost! Have you ever seen a 70 hp electric motor?! They weigh well (!) over a 1000 pounds. BTW, 70 hp at 12V is something like 4,300 amps! Centrifugals use a little less than positive displacement blowers like the Eaton, but not that much less. One last little factoid, more boost, more hp to run the blower.

Note: there may be some who will argue that the numbers that I just quoted aren't exact, but I guarantee they are in the ballpark.

Bottom Line, electric SC just isn't practical for auto-mo-biles. Hope that clears that up a little.

Regarding the garrett electric "pre-spool" system? I think that design stiffed as soon as turbocharger engineers found that the heat from the turbo charger made the "pre-spooler" operation inefficient and unreliable.

According to the current Garrett website, the "anti-lag" technologies that are operational (at least on advanced technology diesel engines) are the variable geometry turbos.

Why not put a leaf blower under the hood

Well said. You wouldn't believe how many times I've seen this question on Honda boards.

I had a guy that wanted to spot me 2 cars in his neon that used an air compressor

Just one more person recomending to never get an electric supercharger.

i had a 100hp electric motor in the back of one of our company trucks sitting on a pallet one day at work when a guy pulled out in front of me. i had to slam the brakes and it slid up and hit the front of the bed so hard i can't believe it diddnt bust into the back seat

a leaf blower does move alot of air for how much it weighs, how many CFM does it push?? someone should put one on a flowbench lol.

maby they should put one of those electric blowers on a car on tuner transformation

You could probably get more horse power out of a well placed sticker.
