An electric super charger for the 928? Claims 27HP for under $600 - photo gallery shows two installed on an '87 S4.

Anyone heard of this or using it? MM

 

re-post,
do a search, there are some posts and alot of info on this.
I think Mar Kilbort uses them.

 

If I am not mistaken, MK has one of their graphics on the Holbert car, which suggests to me that he endorses it. MK, correct me if I am wrong. From my perspective, if the HP gain is worth the $$$$, it is a good deal if it is effective. I'd love to see MK chime in

 

 

If I'm not mistaken, MK is involved with this company, as in, he helped develop the product or he's a part owner or something. I contacted him about it once. I think there may be issues with him not being a Rennlist sponsor though. He may not be able to talk about it in an open thread.

I think it's a good idea and if it can be shown to work on a dyno in impartial tests, it's worth considering. I'm actually playing around with a similar design with some intake mods to see what it will do.

 

They ARE A JOKE. I know this is gonna get someones pantywears in a bunch, but its the truth. If it was soooo easy and effective we all would have had on along side a "tornado" intake.

 

From the "Company Info" page..

", e-Racing Motorsports was founded in 1997 by two brothers (Mark and Mike Kibort)"

 

No dude, these things are the shiznit. Really. I saw a Nissan that had them, it totally ripped me a new one and he was stock. Except he also had a turbo, and some ground effects........I think what got me off the line was that damn coffee can attached to his bumper.......it made a hella loud sound when he hit the gas.

I had to let out of the gas though, there was traffic and a school zone. But man, I got my schiz kicked. That and some pop off valve scared me when it went "PSsssPOW.......fizzzzz.....Psewwwww"

 

Wow, I never knew Mark was actually in on it. I always wondered why such a great driver and car advertised these. When I was in the parts house biz these were always the laughing stock of the store. Most forums I have ever been on with any make\model car have always proved worthlessness of these.
No offense to anyone but i think they are a cheeeeeeeezy sales gimmick.

 

Why are you still awake? Its past your bed time old fella....

 

They do work and are as effective as any bolt on product, factory or otherwise that i have used, and i have used them all.
cams, intake, chips, air filter, intake tubes, throttle body, heads, displacement, NOS, you name it, ive done it. (for engines 4.7 liter and smaller , or better said, for engines lower than 240rwhp)

The eRAM works for one simple reason. an stock intake has restriction. Ive measured it. on a 928 you get near .5" Hg at WOT at 100mph! the eRAM can neutralize this and add a slight pressure. on smaller engines, the pressure increase is actually much higher. keep in mind, the eRAM blows near 1000cfm, so when the requirements are near 300cfm, like with a 3.2 liter engine at 6000rpm, WOT, pressure is generated.

On the 928 with 235rwhp, we got gains of near 8hp . on smaller engines, the gains are near 5%. on several 911s we got 10hp to the rear wheels. Scot Graham's 911 was one of them. the interesting thing about this mod, is that we can turn it off during a dyno run , and watch the HP curve dip back to the baseline. when i added this thing to the Holbert car, it didnt add much HP, but did broaden the HP curve from 6 k to 6600rpm. I use it racing.

Now, is it worth it? well, if a broader hp curve is worth it, then yes. if you are looking for more HP on a 928, only the 4.7 engines and smaller will benefit, unless you use two of them , one on each intake tube, as shown on the website. (but, thats expensive, near $600)

Now, if you doubt the pressure generating capabilities, you should see one in person. they are quite amazing. 65amps at 14volts. Thats near 800watts.
On 3.2liter engines and smaller , substantial gains are seen.

In the works now, is a new model that uses a DC brushless motor that draws near 100amp at 48 volts! thats near 5000watts! Its going to produce near 2 psi and work on most any car, even up to 5 liters. 2psi is near 12% gain, and thats nothing to scoff at, even though the price will be near $2000.

Anyway, thats what you will find on the web or on prior discussions.
Its not one of those 2am 12v boat vent blowers that you see on ebay for $20 or a squirrel cage centrfugal blower for near the same amps and cost.
It does work, but it is a racing play.

Got tomorrow off. What **** are you looking at tonight?

 

Mark, if the electric supercharger kit for the street doesn't already shut off the alternator at WOT, then it should be added to it. You could get a few extra HP at the expense of some battery life. But for the track, the battery would run out quickly...

 

Forget about using battery power. Just get a 20,000 foot extension cord, and a very big reel to store it when you're not at the track. OR....maybe a lightning rod and drive during thunder storms. Yeah, that's the ticket! Seriously though, if you're going to go through the trouble, get a real supercharger.

 

Battery power is one of the great unused energy potentials in your car. Its just 50lbs of dead weight with 500-1000amps waiting to be tapped on. (do the math, 500amps x 13volts = over 5000watts! and it for a decent amount of time!)

a real supercharger is a great idea as well, but this is easy to install and gives the gains of any other 3-500 dollar bolt on.

If we had unlimited resouces, we could really design this thing right. Ive seen axial flow compressors on some of the old airliners in the 50s. they are two stage devices and move a lot of air and generate pressure near 5psi. with our use of the dc brushless motors, we know we can get very efficient power to generate pressure and flow in the 2-3psi range. The problem is the voltage and controllers required to do it. with our prototypes today, we are approaching 2psi at flow rates of near 500cfm. (these things are putting out near 15lbs of thrust! The are like jet engines!) anyway, if we can make this set up for near $1500 and it is dependable power that doesnt add much weight to the the car, it certainly would be something i would use at the track. 12% power gains when you are WOT. Thats a 36hp adder on top of 300hp.
