Electric Supercharger for LT1's ?????
whatever, if it wern't for entrepreneuers (I know I spelled that wrong), where would we be today? I say let him do it and find out for us, because it has not been done, or if it has we don't know about it, and we're running on theorys here, and yes I know these are strong theorys. Let us benifit from his actions and thoughts. Who knows, maybe he'll gain some power, no we don't expect it to be 50 rwhp, but what the heck. I say go for it.
Small, propellor style fan blades are not capable of developing significant pressures. They produce "inches of water" level pressures, not "psi". A highly efficient Vortech centrifugal S/C will consume 5 to 8 HP from the nose of an LT1 crank for each "psi" of boost it produces. That means it would take at least a 5HP electric motor to develop 1psi from an effcient centrifugal blower. Since you are using an electric motor, that energy needs to come from the alternator... which consumes HP in proportion to the power it produces. And as I recall, 5HP is about 3.8KW. At 12 volts, that would mean over 310 amps out of the alternator... ooooops, wait a minute, that would mean we need 3 alternators driven off our serpentine belt......
And how much power do we net from 1psi? Well, if your engine makes 300HP at normal atmospheric pressure, you would gain 1/14.7 X 300 = 20HP.... maybe just about enough to drive three alternators......
. Then there's the loss in performance from all the heavy alternators, wiring, controls, the fan, etc.
Are you starting to see how, when you apply sound engineering principles to your idea, it falls apart.

Now when it comes from someone that knows WTF they are talking about, and can back it up with mathematical equations and formulas it starts to make sense, but un-backed-up accusations just dont mean anything. Thanks injuneer, maybe you saved him $100, but maybe hell still try it and break the laws of physics....
i have actually thought about it.. wanted to try it with the duct fan we had in our garage... till i saw my dad threw it away. from there on the idea died with me
i say go for it and lemme know how it works.. im very curious to see

I really appreciate those of you who are inquizitive about new idea's. I'm not saying it would work or even add a significant amount of power, but if properly designed it could be a cheap way of adding a quick boost for a 10th or so. I appreciate Injuneer's facts and how he presented that info. That was much cooler than saying "Thats the worst idea I ever heard," without backing it up and then sudenly agreeing with someone that's educated about it.
Thank god for positive people!!!
Negitive Old fart's can kiss my A$$
Thanks again guy's , Good lookin out!!!!!!!!!

Yes I have seen it done before. Some 'tard put two electric bilge pumps on his LS1, and shows it off like it's a power mod.
Instead of spending 100$ on a ducted fan motor (which has a service life of what, 1000 hours?), buy a CAI, some LCA's or something useful.

thats doing it yourself
your idea wont work enough to justify doing it
there is only so much room in the intake manfold
meaning you can only get so much uncompressed air in there
but if you compress it, like a blower, you can get more air in there because its compressed

Ok so here is the thing if you wnated to control the speed of the electric blower with the throttle all u have to do is take a dimmer switch and with a metal extension off of it so that it would turn with the throttle my friend and I already did this with a toro leaf blower but only got 2 psi of boost
Ha we couldnt get a power inverter big enough so we just plugged it in the wall so I guess you would need like a little over a 1/4 mile of extension cord ahahah as far as cfm rating I dont remember Ill get specs though later but we toasted a 400w power inverter by hooking it up to that
I have also thought about the power inverter Idea as well. Most leaf blowers are12amp motors. 12amps x 120 volts =1440watts. To get an inverter that big costs like $350 and leaf blowers are like $50.
Another thing I was pondering. If you go to Prochargers website, trying to remember here...on of there blowers says like max 1200cfm @24psi. Well what would the CFM be @ 6psi like the set up for our cars. If CFM and PSI are proportional, then a supercharger for a lt1 would only be moving 400cfm of air and I have seen leaf blowers at sears that advertise 405cfm. So this would e similar to a 6psi blower for $400 right???
Something else you might want to try...make some kinda valve to be able to suck air NA when you dont have electric fan on or it will just act like a big restriction.
................Just some stuff for yopu guys to think about.
