Eram Supercharger intake-Beware

[mgreen84]

Most of you guys are probably smarter than this, but.......I work for an aftermarket auto parts retailer (remain anonymous due to differences in opinion regarding parts suppliers) I just returned from a Aftermarket Expo we were invited to in Atlanta. A supplier for the new "fad" electronic "supercharger" (basically an electric high RPM fan inside a high flow intake to "push" air into the engine) intake systems was there to show the "Benefits" of their product....to make a long story short... a lincoln Navigator was dyno'd fitted with the "Amazing" intake and ran again....Drum Roll Please.......2.1 Horses!!! and a ground shaking 3.2 lbs/torque and to beat it all the intake was ONLY $599.00!!! .............Be aware this is such BS!!
You would get more from a K&N Kit! Thats sad not only is it not a sucessful "supercharger" it barley functions as an intake!!!

the "super charger" probably ubstructs airflow with the fan cuz the fan can't keep up.

Yea this has been talked about on import forums for years now since the E-Ram came out. Ebay went nuts over selling marine blowers as knock offs. Beating a dead horse..... no one buys those things, thats why they are at "expos" trying to find anyone to sell their products let alone buy them.

Bored (and probably drunk)one night a buddy of mine hooked up 4 of those Marine Blowers to his commuter honda....actualy made a difference in power...then ran to lean and blew the motor :roflmao:


The computer had no idea what was going on...but shows thay can add some air



Still...don't do it

Ummm Im going call BS and say I would have to see a vid of this to belive it. If you actually take one of these "products" and check the CFM it pushes a car idling pulls way more than they push. It only restricts. Also with the fins for the fan it cuts down on the actual size of the tube you are using since you just took out some of the cubic inches by displacement.

Also a stock "honda" can eat up a 75 shot of nitrous with no FMU, larger injectors or the like. So it is improbable that your 4 marine fans pushed more O2 than 75 shots.

average marine blower is like 200CFM x 4 = 800CFM...thats a lot of air...no doubt that will run lean and blow

Porny...It was a mid 80s shitbox...you look at it wrong and it runs lean...


I don't know what size they were... about 4 inch around the fan...maybe a 2.5 inch outlet

and it wouldn't idle with them running, they were on a switch to use like nitrous

It actually dont work like that. Kinda like saying 2 rigs at 60 mph hit head on its like a 120mph crash. Not the same. You have to put into aspect that the next one will not push over 200cfm. That is its max load. Ive done these tests when I used to build import drag cars. Been there done that, its ok your buddies rig blew. Guess it wasnt as strong as this lawnmower

Tried to find ya the one with the retal car on the dyno shooting the nitrous straight from the bottle (no jets) into the intake manifold...... no blow. One thing tho, did ya rev the motor out when you did it??? Do you think it would have done the same thing reving it out even without the blowers?? Im thinking it just blew because it was a POS since you stated that.

Anywho none of us are buying the e ram so off to a new subject.

Personally I think the price tag is a real joke, but I am curious, what where the exact test conditions? Was it tested at Idle, in gear at idle, or at some elevated rpm and real load. If it was 2.1 horses added to an idling 21 HP output (idle in first gear lets say) then 2.1 horses is significant, like 10% increase, not cost effective, but significant. If it was 2.1 HP added during a heavy loaded test at say 200 HP on the dyno then its like a 1% increase and not that impressive.

If was built in China and sold for $59.99, it might be worth it?

Somewhere out there is a real live electric supercharger- I forget the link, but it was basically an Eaton M62 or so with 3 big electric motors powering it. I can actually see that making some real gains, but then your electrical system's gonna need some oomph to run it.

Those 4" inline blowers are rated around 200 CFM at a tiny pressure. Put in on an intake and you simply won't be able to generate any kind of pressure or boost. There's a reason why mechanical superchargers consume upwards of 20 HP. That little $20, 0.06 HP vent fan motor isn't going to do much of anything.

A $20 vent fans run around 2500 to 3400 rpm, the one I have been researching today from a sister thread here (I think the one this guy was originally talking about, but not sure since he did not list the details) runs at 25,000 rpm and has a 1 psi boost, pulls 50 amps, and is only turned on briefly at WOT by a micro switch you mount on or near the throttle body linkage. Peak flow is 800 cfm, and it is only 3" dia. Its the 25,000 rpm that does it, its a axial high speed turbine fan.

There is also a cheap centrifugal low power blower out there that does fit you description.

Still 1-psi boost is pretty small, even for $300. THe original poster mentioned a gain of only 2.1 HP. I'd think you would see much better gains by putting a header and better exhaust and improving flow that way.

These are out there. They aren't popular because of the cost and they were eating bearings like crazy(I think). Plus the draw on the alternator was pretty high. You'd end up having to upgrade all your electrical. I've always liked the idea, and fiddled around with it a little. Would work great in applications that had space issues. You could mount that thing anywhere in the vehicle. The guy who holds the patents on most of the electrical superchargers found that the three motor design was the best performing to amp draw. I believe it was better on the bearings too. I personally think they would be best suited for hybrid cars. The electric charger could run off the batterys and give the gas engine a boost for passing and such. Just my $0.02.

I would still like to know which one he was so down on and talking about and at what part of the operating curve that was at. In my case 2.1 hp added at idle would be huge for my 2.2 L deisel. I have decided to at least set up a cold air intake on mine first. Also at WOT on my deisel a 6 hp boost would be a 10% increase, and 2 hp at mid range rpm (peak torque on my deisel is at apx 2000 to 2400 rpm) would be significant as well.

For the 4.0 L Jeep engine it's nothing.
