Anyone???

Looks like a nice boost to help with lag. This is on until turbo is fully spooled.

oh no! lol those dont work, sorry

These used to be a running joke 5 years ago on the old e-mail list. I thought is died a quiet death. Maybe not.

Who's 928 is on the site? Pray they didnt put one of those in....

Mark Kibort is on their site. He is a rennlister, I believe. I have seen him post in regards to how a modded 951 stacks up against modded 928s on the track. I believe he has been successful on the track with his 928.

Actually, it appears that Mark Kibort owns eRACING, LLC which sells this electric supercharger. Wonder if he will chime in on this. You might want to post this to a 928 board.

If you look at what a turbocharger or a supercharger has to do to deliver horses, this thing is a really serious hairdryer, but it doesn't look like it's capable of useful forced induction.
I've read posts of people saying it doesn't work.
I haven't read a post of someone with a car doing berfore/after dyno runs to prove it does anything useful. Still, 4% horsepower gain for $299 plus installation time. Cheap horses, assuming you don't intend to do anything else to your engine.
Even so, I look at it and wonder if it could hurt horsepower -- I doubt it. As long as it significantly exceeds the CFM needs of the given engine, and their 1 psi claim probably doesn't require a lot of power itself, so it might not actually hurt.
Note the "hoops" to jump through in the guarantee. It requires doing with/without dyno runs to prove it doesn't work before they'll reimburse (although they spell it reimbersement ... ) you up to $50 for the dyno runs (you'll spend $200 easy) and all you have to do is spend a day putting it on and another day taking it off and wait for your $299 in the mail. There's worse ways to experiement with your car.

Its a builge pump motor and not a very good one. Dont bother with it.

If you are seriously interested I in an electric supercharger I do think that some larger turbo diesel trucks use true low rpm electric superchargers. And yes I do think they work at low rpm's, but they are not cheap. That builge pump blows about 180 CFM or so. Its like a hair dryer....
Look up any marine web site and search for electric builge pump. I just put one in my boat last summer! 20$ and its exactly like that one>..

Oh yea, It cant compress air, its just a fan...
If you put your hand over the end you can hold the pressure with your hand.

FIFTY SEVEN AMPS?

If there was ANY horsepower gain, which I seriously doubt, it would be negated by the increased drag imposed by the alternator, trying to recover from the fifty seven amp draw.

In respect, the supercharger on my "other car" can rob up to 40 horses at full boost, just to compress the air charge. Think of how big a 40 hp electric motor would be. Again, can't have something for nothing!

take a look...

57 amps will make about 700 watts. less than a hairdryer (most are like 1000-1200 watts). youd have just as good of luck snorkeling the intake into the cabin and blowing hard. course, youd get tired after a bit

So people are happy with the principle but not the power of the unit?

I'm not about to start arguing in favour of this thing (other than to say someone had an interesting idea for making money) but I think it does rather more 180cfm. The real issue would be the cfm at the claimed 1psi boost -- if that's their real claim, sometimes it's "boost" sometimes it's "compress" and sometimes it's just fan.

I don't think this is the same as the bilge gas extractors and those things don't spin at 10,000+ rpm.

Again, I don't see how this could harm, but I don't see how it could really feed enough air to encourage even a smart engine to enrich or advance enough to matter. Can anyone really feel 4%?

Thanks for the link to halfbakery -- great site.
