the e-ram, my experience Options

[celicaST]

ok, first off, this is NOT a thread to debate whether this product is beneficial or not (ill put that to rest soon enough). ive argued the idea of an electric supercharger on the other thread, so NONE of that here. plus i guarantee you will lose the argument this thread is to document my experience with this controversial product. i realize im taking a gamble, but for $300 i figured i might as well. i wouldnt have bought it unless i was confident it would work. this is what im getting for those who dont know. it is a 833watt, 25000rpm motor capable of delivering 800 CFM in free air
2006 e-ram
it will be installed between the throttle body and the existing stock airbox so as to retain cold air intake. so ill be the guinea pig, and i will post my honest impressions after installation. before you ask, i will dyno only if i can find one nearby, and for a good price. if youre so inclined for proof, feel free to paypal me the expense
also, if all goes well, i plan to run the motor at 16.2 volts to increase its power to 1135 watts to increase boost pressure.

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.

from the eram website N/A mr2 (more than likely 5sfe)

my car with just the injen short ram with heatsheild.

for anyone not paying attention to the dyno sheet. the eram dyno lost about 10 hp compared to mannys bone stock 5sfe

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.

the moral of the story is this...

the 5s (MR2) is at 104.2 hp to the wheels stock
the eram added a +3.2 hp for a total of 107.4

Manny had his 5s dynoed (before the turbo) and he was at 114.6 and 115.1 hp (with only and Injen SR intake and stock cali-spec exhaust which has 2 cats).

anyway, $300 for 3 hp ? about $100 per pony. A swap with an average cost of $4000, starting out at 105 hp and ending up with about 190hp = about $47 per pony.

edit: spelling

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.

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.

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

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...

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

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, 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
