so i have a 88 se with 129k miles on it, i would just drop in a turbo rotary, but since i am not the true owner of the car i cant. my dad came up with an interesting idea that he wants to try off an idea my buddy gave me. his idea was taking a 32cc common yard blower and using it to create boost for a vw, which was previously done and worked. i am going to build kind of an electric supchercharger. ametektmd.com sells electric motors and blowers, the motors can range up to 15,000 rpms and the blowers run up to 39 cfm at a 12 volt current and 242 cfm if i can get 120 volts to run in my car. i can run even higher cfm if i can run a higher current in it, and the motor/blower setup does not get to bulky. i am not sure how effective that much boost will run but i am sure that it has to be more then a leaf blower. i am looking to make just a few psi has anyone tried this? i really need some input on this before i start spending hundreds on this electric charger system i want to do

I just found it an interesting idea that whenever i want i can change the boost level and run it at full boost at idle where the rotary lacks the most, no only that but the na's burn rich, so hopefully it will thin out the mix and will burn better at the lower end range and every 1psi put on the engine i heard you gain 9.5-10.5 hp. not only that you dont have to play with the serious heat from the exhuast, and you dont lose hp from the crank like a supercharger does. and the setup does not weigh a lot, the 10,000 rpm motor only weighed 5lbs.

Well since non turbos can draw over 242 CFM, as proven countless times, in countless threads here, your yard blower would not work for any car for the following reasons:

#1 insufficent volumn of air
#2 insuficent pressure
#3 Insufficent power to supply enough current to push an electrical motor at the speeds to overcome #1 and #2
#4 Insufficent size of the blower's runners to not be a restriction even when the blower is off.

So, anyone telling you that he has made something like that work, is probably smoking crack and has no clue about flow dynamics on a automotive intake system.

Thread closed, won't work on paper, well alone in a car, and has been tried and covered countless times.

BTW, the only effective Electric super charger system, uses three 70 amp electric motors, to move one single blower at high enough pressure and volumn to provide up to 1 PSI on a automotive intake.

Not sure what the amperage draw of your motor is, but I would suspect less than even 7 amps at 120 volts as most household wall recepticals are rated a maximum of 10 amps.

<edit... just to see the other responses I am gonna re-open this thread

Just to see, lets look at the high voltage flow through blowers from the company you mention... lets look at the highest flow 120volt flow through they have...



Whooops it sure goes flat fast... not even enough CFM to boost a car at idle, well alone needing 250 watts to do it...

Icemark is correct to a degree... the electric supercharger system I believe he is talking about is the Eram. It has been out for a while but is not popular simply because it is a $400 system that yields very little gains. I have however seen a blower motor hooked up to an intake of a civic dynoed and it yielded another 7hp give or take which in my mind is not bad. This is just too expensive for what you get if you can even get it to work. Stick with regular bolt ons or toss a 45 shot of nitrous in there thats of course if you cant afford a TII swap.

Check google for eram it may come up
I did it for you http://www.electricsupercharger.com/

Icemark

No, it wasn't eram... the eram only draws about 58 ampsand uses about 883 watts to produce the 1 psi.

I wouldn't consider only 1 PSI max being useful for anything

Think it was the Boosthead.com one, with their base model producing around 455 CFM at around 6 PSI

7hp is small enough just to be a dyno flux, the car isnot going to be 100% the same every time, and operators can pretty much make the dyno say what they want it to.

you mean the CPracing (some say not the CP racing we know of ) video with a gas yard blower hooked up to a civic EP3?
they unhooked the intake filter, and jammed in the blower?
yes in the video it did yield about 7-10hp. and it did it again for a truck to make sure...
but i don't see how u can mount such a big blower in the car.

there is the thomas knight electric supercharger kit. it makes about 6 psi @ 355 or so cfm, cost $1300. it uses 3 modified car starter motors and 2 additional batteries to run and a boosted alternator to keep the charge. it can be used in 15sec bursts. and fits in just about any car. but $1600 or so after install and batteries and whatnot.

well damn that just shot down my fun idea, guess im not going to be running it off the electrical system. the amps was the one thing that had me leanin towards it wasnt a very thought out plan. oh well i guess i can spend my money on something else like computer tuning and exhaust

if you want to try it for fun get a gas powered blower and try that, boot the electric motor idea out the window because of the current draw and lack of CFM. the gas powered blower may not be workable for a full time solution but you could maybe do a few runs down the block.

in SC you only need wheels and a windshield for your car to be legal on the roads, lol
