Capacitors installed into R/R for improved reliability

I originally came across this idea based on this link:

http://autos.groups.yahoo.com/group/...ing%20project/

After looking thru the information I had to agree. No different than installing capacitors into the electrical system of a vehicle with oversized amplifiers to help dampen the electrical surges that would otherwise wreak havoc resulting in eventual alternator death...

Anyway, after coming across the info, I purchased a set of capacitors BETTER than the Radio Shack cheapees mentioned in the article. I have 3300 uF capacitors rated for 105 degrees Celsius (221 F). This should effectively double the dampening capacity of the installation the other guys used.

I am considering putting together a 1-stop upgrade kit for the R/R that would include everything including a custom mounting bracket waterjet cut from aluminum.

For those that are interested in the capacitors and have the other portions of the upgrade done, I can supply them go at $14 per pair + shipping. You can contact me [email protected]

$3 for a set??

I will give more specific information:

16V 3300 uF rated at 105 Celsius (221 F) Radial Lead (both leads on same end, not axial)

Radio Shack provides nothing within these specs. The closest is a 4700uF rated again at the LOWER 60 Celsius temperature range axially mounted (more difficult to install).

I'll requote at $12 per set + shipping. Good luck trying to find anything similar at Radio Shack. I tried before I located these.

will 12$ include this custom bracket? i can see the shipping charge around 7-10$ location dependent.

how these caps preform on in the long term? i mean they will be filled 24/7, they are not ideal there will be a current (even if very small) that will go through them . i woud also consider making a discharge sircuit (maintanence) so not to have to loaded hidg capacity caps while working on electrical system

These capacitors are not like the large 1 Farad capacitors in high power car stereo applications. They are located on the power circuit between the R/R and battery.

The price is for the capacitors only. They are not large. About 3/4" diameter. I can place in small bubble envelope and mail for around $2-$3 I think. Haven't checked out furthest location yet or cost of shipping materials.

Capacitors always have a charge on them unless discharged.

The bracket would be extra. I have not yet had a chance to investigate this yet. You could replicate what the other guys have done with a simple piece of strapping steel, u-bolt, and associated hardware for now. I need a chance to sit down and design something in the computer, create prints and get quotes if feasible Will post more info on this later once I have a full kit figured out.

To answer the previous quote regarding why waterjet cut versus jigsaw cut:

I need to provide consistency in fit,finish,function of the end product if I were to supply to people. Water jet is just like running a laser cutter without the problems of "attempting" to laser cut aluminum. Process is used in the aircraft industry extensively.
