I'm mounting my rectifier to the scuttle engine compartment panel. Is it better to mount the rectifier to a thick (say 5mm) plate, then bolt that to the panel itself...

or

Is it better to try to get air to flow above and below the rectifier. I previously had the rectifier mounted about 5mm off the panel and had a computer fan blowing down on it. But, I did manage to kill the rectifier...

--Thanks, Chris

I believe the general cocensus is that your new regulator is more robust than the standard Fireblade one.
If it was me I would mount it on a heatsink of some sort, like your ally plate and that should be able to cool to the air

Try a good computer heatsink as well as a fan, and attach that to the bare side of the reglator, preferably with some heatsink paste. I had an old Athlon heatsink on my blade rectifier (because Athlons of the time needed more cooling than Intels) with the fan rigged up and it lasted fine until I sold the engine last year, so Ive done the same to the R1 rectifier on my new install.

Gents:

Thanks for the reply. I hate to ask this, but when you say heatsink, what do you mean?

i mounted mine today. Its just cable tied to a bar, sort of swinging in the breeze. zx9 rectifier includes a heatsink, ie metal vanes.

Chris,

The Superdream rectifier already has a heatsink (fins) on it, I would just mount it to the chassis, I'd see ho it goes without the fan as it shouldn't need it now you have changed it.

Mine is mounted exactly like this and had no problems since I changed it for the superdream one.

Joel, worth noting that the rectifier gets hot enought to melt a cable tie!

HTH,
Rich.

cheers rich, i'll have a fiddle with it today then!

Hi Chris

By heatsink Imean the aluminium / copper finned part that sits directly on top of the processor, with the fan on top




As the Superdream one already has fins / heatsink on one side then you might not need or be able to fit one, but on the standard blade rectifier it seems to do the job.

Chris

Ahh, I see what you're saying now. Many thanks gentlemen; this helped a lot.

Chris,

Would be very interested how you get on with the wiring as obviosuly if it works fine then it may help others who have this type of wiring on their rectifier.

ta,
Rich.

Thanks Shortie. I'll wire it up late next week and will indeed post an update. I'm sure all will be well, though those additional two wires have me a bit worried. I suppose the worse that can happen is that my entire wiring loom and all engine sensors can burn to the ground

Out of curiosity, why does the the Superdream R/R need to feed a source such as the clocks? Personally, I hoped to feed into the fan--as that is the cheapest electronics bit on the car.
