A cap across the fp terminals?

[Sachelle Babbar <sbabbar@iris.nyit.edu>]

I used to, read that:stil do play with radio contorlled cars. That's where
I got much of my electronics experience. I was wondering, what would
happen if I put, say, a 2200 microfarad cap across the fuel pump
terminals? I would be led to believing that this would greatly stabilze
the voltage going to it. When I measured voltage across the terms. on my
rc car, the motor was recieving slightly higher voltage. Probably .1-.2
volts more. The only reason I haven't aCTUALLY DONE this is because of the
ecu. I am led to believe this idea being safe. Point is, the rc car
performed much better, the brushes lasted longer, the motor ran most
definately cooler (reduces pulsing from the speed contoller, I was using a
high freq. one also). A slight increase in rpm is very noticeable. What
does all think? Can it help with longer pump life? Better flow under
varying electrical conditions? I am led to yes on all. I think I convinced
myself to try it. If the car doesn't blow up, it's safe enough for me. By
the way, the high the freq. of the power going to the pump is, the less
arcing. If power os steady (flat), almost none.
