They're bilge blowers off boats. Worthless.

There was a long thread on the 911 side about this a few months back. Some sales guy was singing the praises of the idea, but some of the engineers proved scientifically and mathamatically that it was not possible for it to do what is claimed.
The current draw neccessary to provide even slightly boosted induction would melt the provided wiring within seconds. It basically amounts to an obstruction in your intake, and a reduction in electrical power. Got pretty heated. A guy offered to pay for dyno runs. After many silly excuses and delays by the supporter, finally two different cars, a 911 and a 928 were lined up for dyno runs with and without the electric supercharger. The engineers were proved right. The electric supercharger was worthless. Then it got really funny when the guy promoting these things complained about how the dyno runs weren't fair. He was at the dyno, and approved of everything, but when things didn't go his way it was like kindergarten all over. That was some of the most entertaining reading ever on the 911 side. Bottom line, don't waste your money. |

A bilge blower will work, just not on a 2.5 liter engine. Small two stroke engines are another story...

Well a lot of different things could work.
But those two things I posted have been proven to work. The Eram is from one of our own. And has been proven again and again at the dyno. Their was even some stuff on here if I recall about it. The ESC from Thomas Knight. I have that issues of those magazines it has been featured in and one of the guys in our car club has one. Its a little screamer, beats Nitrous by a mile. The only problem with it is cost. |

Look at all the added weight from the ESC, 2 big battery boxes and a huge SC with starter motors attached to it. Sure it will show HP gains, Just like the leaf blower does, Big problem is they are eather ON or OFF and there seems to be alot of added weight, Eram looks a little better but again its a WOT system and the price is high, For another $200 you can get a fully adjustable nitrous system(25-75hp) with only about a 10lb gain. I really think that If you set up a nitrous system to the same HP gains as the ESC that itt will not get blown away cus again they are both WOT systems

Go to the 911 board and do a search for E-ram. Plan on spending quite a bit of time....

Well The ESC has seen a couple of variations from what I read and see. Including a Centrifugal version. The Centrifugal setup is what I have seen in person.
It uses 3 Small 11lb 680cc optima batteries - they look like motorcycle batteries. Its boost on demand and no bottle to fill. According to the guy running it. He can get 10-12 runs out of it at 15-20 seconds. He has run it up to 30 seconds, but he finds that you really dont get to be at WOT for that long. His commment was that even if it was full time, how often would he get to use it? Even a turbo. In daily driving how often would any of us be in the boost and accelerating or running full out, before you break the law or risk someones life? As for the track. I run my ranger, it turbochargered and hauls. But I have to have the revs up to be in the boost. Nature of a turbo. He can launch with boost and keep it on the full length of the run, and do it over and over, then cruise back to the lineup and the alternator just charges the batteries back up. He said he has all of 1500 invested which is more than a nitrous system, but as often as he used his nitrous, he has already saved money just on having to fill up tanks. Plus The heat of nitrous combustion isnt their nor the risk of having a bomb in your back seat or trunk. Who knows. One thing that did interest me. They have a small version that supposedly can be used to kill lag so that you have instant boost and the turbo handles everything after you disengage it. Charles, the guy with the ESC says it could be setup to handle all that and the cost would be less than 1k. To use it instead of a Nitrous setup for better launches. I think with better battery tech and better motors the system would be fantastic. |

For the cost, you could just add a turbo to most cars. But you have to worry about a lot with a turbo, install, oil lines, header, downpipe, intercooler, etc. With this thing, it can be mounted anyplace, not belts, no lines, etc. Just a one way valve that closes when it engages and an extra injector to handle fuel. Whatever; it works! Dollars to donouts you could probably do it cheap and reap the benefits, the only big cost is the unit. |
