First SS build

[xsuperbgx]

I ordered a cartridge heater and I am building a load tester like these: http://www.xtremesystems.org/forums/...ht=make+a+load
I am assuming that an aluminum block will be ok for this?

Not the best, copper would be preferred.

Its turning out very good !

Good to see some frost keep up the good work.

Adam is right about the copper but if aluminum is what you have, by all means us it.

Thanks. I found a place local that sold me a scrap piece of copper 1"x 2"x 3" for $16. So I am set there. Just waiting on the heater element now.

I am working on charging this tonight. I built a load tester with a 300W cartridge heater. I am charging it with propane. Right now I have a Low side pressure of 8 PSI and a temperature just before the accumulator of -10.5C. Using this chart it seems to me that my superheat is around 15. Could someone confirm that I am figuring that correctly?

Also, My load temps are about -18.5C and my compressor temp is around 102-104. That is with a cap tube length about 8'. Do these temps seem ok? Ambient temps are 20C or so.

Looks like it works ok. I am benching a little yesterday and today. Seems to work do what it is supposed to. I haven't benched anything with high load yet, but amd quad cores seem to set at -26 (evap temp) or so with wprime1024 type load. i will put some finished pictures up when I get a chance. I am already feeling the urge to do something a little bit more extreme.

Thanks again to everyone for your help!

Outstanding xsuperbgx!

I ran my 2500k on this single stage yesterday.It is the largest load that I have run on it. I improved my results and felt comfortable with my voltages and temps. It is very convenient compared to having to get dry ice or freeze my tail off in outside winter temperatures. I haven't taken pictures yet, as I need to trim up a couple of the shrouds, so it will look decent. Temperatures swing very little on the 2500K at 5600 Mhz.

I have been using this for a while and it is working well enough, but with an 4930k setting here on my shelf, I am thinking that I may need to increase the load handling capability. Will I need a larger evap and a different gas? or should I just shorten cap tube and retune?

[runmc]

What size and length cap tube did you use?

[xsuperbgx]

It is .031 captube. I didn't make a note on length but if I recall correctly, it was about 8'.

Perhaps some clarification of my questions....

Is that little evap capable of handling more wattage?

And, will increased load handling be possible with the R290(BBQ gas)?
