i know that some of you have already posted on this but i have a tech question and i hope that you can help. say if you had an ELECTRIC SUPERCHARGER that you could install in line and it gave you ,say from 3-5 psi boost or maybe just a little more. would this make the mixture too lean and burn up the engine or would the afm compensate for this and make the adjustments ? if not what would i have to do to compensate for this extra forced air. a friend and i have made a device that does this and i want to get all the info i can before i install it. going to put it on a 88 na 13b. let me know what you think. thanks. PEACE> ex...

 

There's a reason no one is touching this... overall, it is a bad idea.
I would like to see this working design of a pump from you and your friend.
3-5 psi of boost would be fine on your car.
S/c should draw through the AFM, and not blow through.
AFM would compensate for this increase in airflow with more fuel.

hmm 3-5lbs is more than i thot they had.

do you got a website for those electronic superchargers?

 

All premade ones claim 1/2psi to one psi. as far as I acn tell, he is claiming to have built an electronic supercharger with one of his buddies.

here is one web sitehttp://www.electricsupercharger.com/

 

I think the hideous women at the bottom of their homepage speak enough about the product if the company isn't doing well enough to hire attractive models...

their testimonialshttp://www.electricsupercharger.com/...am_testim.htm?

 

sorry to hear that you relly on a beutyfull woman to tell you a product is good or not

side note : i do not have the product nor i am defending the product
the reason i posted was because i did some search to contribute to the threat


so dont take my coments to heart ya know what i mean

 

i am interested on the points of view of what other people have to say about this product
and when i say people i mean rotary enthusiasts

 

it'll work for a few mins before your battery goes dead.. this is ment for very short use like NOS.

it draws 50amps...

 

i would want an afc if i got that, i wouldn't trust that if it was in my car...something about it just seems kind of ghetto. it is a good idea though.

 

Quoted from an article from Autospeed, explaining why electric superchargers are useless on cars:

"So, how much power does it take to drive an efficient supercharger like a screw type? The most efficient type of supercharger, flowing 265 cfm and developing a boost of 11.5 psi, takes 14.5kW to drive it. Figures aren't readily available for centrifugal blowers, but they'd be of a similar magnitude. So the best blower design (the same type that's used on the Mazda 800) takes about 14,500 watts to drive it on a modest-sized engine. This power is derived from the engine via a belt connecting the blower to the engine's crankshaft.

But let's say that instead of using a belt-drive from the engine, we power the supercharger by using a 12 volt electric motor powered from the car battery. For an electric motor power of 14,500 watts, we'd need a current flow of about 1000 amps (14,500 watts divided by 13.8 volts = 1050 amps). So, to supply the current to drive an electric supercharger having the same airflow output as the most energy-efficient type currently available, it would take 1000 amps. To generate this much electrical power would require at least 8 heavy-duty alternators bolted to the engine. Furthermore, to handle this current, the wires connecting the battery to the supercharger would have to be enormously thick - perhaps brass or copper bars 10mm square would be needed."

 

what a bunch of horse ****.
