I think the capacitors does one thing--it prevents my transponder from cutting out under full throttle.

Power Capacitor to gain acceleration
Guys;
Your arguments remind me of the Global Warming and Ozone Depletion theories.
Each one has Scientists on complete opposite sides of the issue, with mountains of data to support their particular viewpoint.
All I can say is, if you're running (in Stock) without a Big Cap, try one and you WILL notice a difference.

The one in this thread is 2 for $10 for the same one. My friend will be jealous, then I will give him the other one.
I am running a micro with 2/3A's. The other thread said:
"Runing micros I can say for sure that power caps do make a difference, they are especially noticable with batteries that have less output like AAA's that they are with 2/3A's."
This might not be as noticable on subC's.

i found some 4700's for 1.25 but they were at 25 volts...does the voltage even matter? well does 10,000 uf 16v do anything good for anybody? $1.50 each...

any cap won't work...
The capacitors we use have a VERY low ESR value....
There are other ratings for capacitors than just Farad & Voltage value...
What is ESR?
ESR is an abbreviation for Equivalent Series Resistance, the characteristic representing the sum of resistive (ohmic) losses within a capacitor. While ESR is undesirable, all capacitors exhibit it to some degree. Materials and construction techniques used to produce the capacitor all contribute to the component's ESR value. ESR is a frequency dependent characteristic, so comparison between component types should be referenced to same frequency. Industry standard reference for ESR is 100kHz at +25°C. Power dissipation within the capacitor, and the effectiveness of the capacitor's noise suppression characteristics will be related directly to the ESR value

The HIGHER the voltage rating, the LONGER the Cap will take to charge/discharge (At the voltage we use). There is a very small, but noticable difference when using 10V over 16V Caps.
Ideally a 7.5 volt Cap would be great, but I think the next step down is at 5 volts and electronics like to make LOUD noises when pushed past their voltage/current limits.

pop, thanks for the info...learn somethin new every day! But at the speed of electricity what kinda time are we talkin about "longer to charge"? What is 1 Farad? Would it be ok to have a 2.5 volt supercapacitor? Says has extremely low ESR. I have a electronics book that has a TON of capacitors in it and nothings near teh voltage yall are talkin about...there are some 10 and 16 volts but they are low except for that one that is 10,000. The only 4700uf is 25 volt

ok would it be ok for the capacitor to be 2.5 volt?
