I think a guy could make a 12 volt converted hard drive motor with
a fan that would do more that that. I have made air sample
centrifuges in a similar manner. A different impeller would have to be used.

Something not mentioned, is that Manny dynoed at the highest hp, I personally, have ever seen on an almost stock 5sfe. Some one else dynoed a 5sfe not but a couple weeks ago with the same numbers as the e-ram people.

I wonder how well it would work WITH an intake/header/exhaust. Since those mods normally don't do all that much on our engines, maybe this would help get our money's worth out of those.

Celica St, i don't know why you posted this new thread before you got it installed/dyno...it will only invoke people to "diss" the eram more...

i guessed the same thing using simple math and knowledge http://www.6gc.net/forums/index.php?showtopic=33592&st=60

you know what every1 is forgetting to mention, this is drawing power, which dosent come from no where, this thing takes away hp to run, like a supercharger except it dosent produce as much boost. a turbo dosent use any mechanical power to run it uses already flowing gases, i wouldnt spend $300 on 3hp, but what ever floats your boat

ok i get back from my vday date, and this is the crap i come back to. come on where is the love?
but seriously, i dont know where to start. by the way, i made the words in my first post bold and big for a reason, obviously some of you guys have trouble showing a little respect.




ok, i asked manny if he had a dyno of his car before the intake. why did i ask? because his dyno post, although is impressive, is meaningless without a previous dyno. it doesnt show what he gained because we dont know what he started with, unless he does have a dyno. we cant assume that his 5sfe put the same hp to the wheels as the mr2 did stock. first of all, theyre not even the same model, and second they arent the same exact car! not all 6g gt's (and certainly not all 5sfe's on all platforms) are going to put down the same hp. engine maintenance can have alot to do with power generated. second, lets assume manny's injen intake did gain more overall hp than the eram did. i bet you it didnt produce more hp and trq at all rpms like the eram did. and im sure you know, that it is the integral of power versus time that will determine how fast your car accelerates. how often are you at max hp when your racing? a split second. so without a previoius dyno before manny installed his intake, his results are meaningless to compare with, although impressive.



read above^ max hp isnt everything. other dynos with eram have shown much better results. read the s3 magazine review of it on the civic for example. s3 review on 95 civic, the gains on the civic were 6.7hp (8.8%) with gains of about 10hp at ceratin rpms. and also note these gains were OVER and ABOVE what the short ram and high flow filter provided, that the civic already had. it was especially helpful at high rpms. your math is sound in second part, but you forgot a crucial point. not all of us want to put 4k into our cars at the moment. some of us are looking for cheaper, easier ways to get modest gains.




hahahaha, if i wasnt so sick of trying to teach physics, i would answer this. all i can tell you is this, go look at a hard drive fan, how many amps does it draw? not even close to being powerful enough, can a hd fan do this? pushing a fire log vs 2hp leaf blower



well with my first post, i thought some people could keep their opinion to themselves, but i was wrong.



ok, the eram draws power from the battery, not the alternator. so when its on there is next to no parasitic losses incurred on the engine, not like a supercharger. also the energy used to run a turbine on the turbo isnt entirely free (althought it is more thermodynamically efficient than a supercharger), it does create backpressure.

now its obvious why manny and lagos make fun of it, because their cars are swapped and turbocharged. but what you 2 need to realize, is that there are plenty people on this site who, im guessing, would like to see this work. so, please from now on NO more, please. unless you like losing arguments, i warned you

when the car is running, the battery and altinator work together. all electrical systems get power from the batter, and the battery gets constantly recharged by the altinator. so if you have more stuff hooked up (like car audio, the eram , etc) it will be more drain on the whole electrical system, including the altinator.

you have my blessing on this project (just cause its funny, lol) but remember to keep a totally open mind to it. cause so far it sounds like you totally expect it to work and give you gains.

i know the battery and alt work together, but the alt doesnt provide 60amps to recharge the battery, which is why i said NEXT to no parasitic losses.

ok it might be funny. and dont you worry, although i do expect a certain result, i will be fully unbiased in my review. im a mechanical engineer, and it seems highly plausible to me that this should work, and i bought it hoping it will (i wouldnt have put down 300 bucks if i didnt think it would). but like any true scientist (who always have a guess of the result of an experiment), i will report what i get. its the results that matter. but, even if this particular product doesnt provide what im looking for (even after i power it a 16.2v), rest assured me and my brother are working on a setup that will

upgrade the alternator then....

but nitrous oxide....300$ for 75shot? thats about 4$ a hp? or so

there is no need to for a intermittent setup.

"but nitrous oxide....300$ for 75shot? thats about 4$ a hp? or so"

true, but must be hooked up properly or we all know what can happen. also, its nice not to have to refill a tank.

why didnt you build one youself instead of buying one? isint that what mechanical engineers do?

uh oh, is that a cheap shot buddy, because it sounds like one

well i take it you missed "rest assured me and my brother are working on a setup that will"

actually, we mechanical engineers desgin things, the machinists and other people build them. but i love building things (and taking things apart ) and now that im certified to use the machine shop here on campus, i take full advantage of it (not always for school purposes ). nothing like having "free" access to vertical mills, metal lathes, cnc mills, saws, welding equipment (although i suck at welding), were even getting a water jet cnc soon to answer your question, the reason im buying the eram now is because if theres one thing about me its that if im going to do something such as build a setup, i want to do it right. what a lot of people fail to realize is the HUGE amount of engineering and design that goes into products (which is why ive learned to greatly appreciate good engineering, such that toyota does). just with our relatively simple setup, we have to worry about many factor such as the duty cycle of ultracapacitor setup, the loads that will be placed on motor, and other problems faced with turbo setups. i dont want it to break after i put it in, or be inoperable. it will take time to develop it to where i want it to be (especially with school, 6gc, and girl eating my time), and we want to use off the shelf parts which makes it harder. and in the meantime, i thought this would be a fun, cheap thing to do. saw the idea posted in the other thread, and after searching i found this to be the only one that even had a chance. and also if it works, all the better

I wouldn't believe anything that has been posted on their own website. After all, they want to sell these things right? What you want to see is a completely independent test. One done by someone who has no vested interest whatsoever.

The only way you are going to prove if this thing has any worth, is to dyno your car as is, then fit the new system and re-dyno. Has to be done under the same atmospheric conditions. Otherwise, it is worthless. Any change in performance on the road could be psychological. And it'd take more than 5hp for you to notice any worthwhile changes anyway. I stand by my convictions which I have had all along with the eRam. Total and utter waste of money. If it was so great, then why aren't more people using them - and even car manufacturers for that matter?

not trying to defend the eram or anything but that mr2 was most likely a older 5sfe with more miles while manny had a 98 that was in good condition. I bet if that mr2 that had the eram had a newer motor it whould most likely make the same numbers manny did or maybe even higher.

Why is everyone argueing about how it works? For all i know, no one here has done it. for a FACT, i know none of you guys know how much power lose comes from an alternator drain. So dont use that as an argument against the Eram. enough said about the alt, unless you know exactly the power lose and dyno proven.

secondly those dyno sheets dont prove much. I can get those gains in power by moving from LA to alaska. The air temperature, sea level, oxygen levels, equipment milage can make the car have an extra 15 hp. For instance a 400k miles old mr-2 in the desert at 130 degrees celcius vs a 2 miles mr-2 at -10 degrees. I know this as a Fact. So dont use the dyno sheets as a liable source for debate.

The ONLY thing that matters with this Eram system is the psi of boost at redline. If you can prove it provides at least 3 psi of boost at redline. Then this is a good upgrade. Dyno sheets will not do anything if the car is not tuned for the boost curve.

guy, if you wanna talk area under the curve, i got that one covered too.
like dustin said, your basicly paying about 100$ per HP with the eram.
i spent about 3500 on my turbo kit, and thats spending in a LOT of places i didnt have to.

thats about a 90whp gain and 100+ft lbs...
that right there cost me basicly 35$ per hp...you tell me, which is more cost effective.
im sorry man, the e-ram is NOT gonna give you what a GOOD intake, header and exhaust is.

according to your math, he will only need to see a 9 hp gain to beat you. So if he gets 10hp will everyone stop disrepecting the Eram?

this is my math:

90hp/ $3500= .02571

this means every dollar you put in, it will give you .025 hp.


with 300 dollars you will get 7.7 hp.


So if the Eram can make 7.7 hp or more, it is better then a turbo in that price bracket.

Notice i said "price bracket"

I know this is not accurate at all. But just for a baseline test comparision.

remember a good I/H/E set-up will cost you more then 300 dollars.

* btw: i am not a fan of eram, i am here to make this thread interesting. FLAME AWAY!*

i got some math for you


Eram + Celica = Slow Car

by your math
the eram is +3whp
3/300=.01
god this is like beating your head into a wall....i double dog dare you to post this on mr2oc...lmao..
