sounds like a nice garage! Sorry to hear about your troubles though, I hope everythings ok now.

had a alot of things happening at once,
someones 4 month old baby die at my sitters(which my daughter saw)
My condolences to the parents and I hope that your daughter is ok.
Bowman, sorry to here about your troubles... glad you're ok! :) The garage sounds super! That'll be really nice when it's finished! We miss you, you know! :)
yah theres been death in my life recently as well
2 different people died who go to my school, and one of them i kinda new.
and someone in my photo class's brother died.
Some of you will recall my son was in a terrible accident last year and saw 2 of his friends and co-workers die at the scene. He's 27 and it messed his head up for a while, nightmares and such. I hope your young daughter is handling it ok.
"garage" or bowman's new mod shop? And BTW, how is that waterblock working out for ya bowman?
Yup, you cannot escape real life, and I suppose everybody goes through this once in a while. It can also take quite some time to get over it, both for you and your kids.
Me myself had a serious traffic accident 4 years ago, and the negotiations with the insurance company are in the last stage now, so one of the guys came by to make financial offers. It has been 4 years ago, but I still have problems when I have to go through all the misery once again. Especially the fact that I am partially disabled and that it will only get worse in the future is something I don't want to think about too much.
Good luck with the garage. I bet you run out of space pretty soon there. No matter how big it is, it will fill up.
Bowman i am sorry to hear all this bed news and trouble that you head for a past week i hope all goes back to normal and wish u all the best...
to all u others i got 1 question to ask sorry if this is not the place but i didn’t wont to open up a thread just for most likely stupid question .
Well my prommy is working all good and everything except i am curious in the prommy control centre i set to -33 for my computer to power up but my computer power up soon as it hits -16 y is that?
tnx heaps
Lano
Well everything is starting to get back to normal.....:D
i will hopefully get back to some modding this weekend:D
have lots to catch up on...:p:
Hello!
Can i use baker GPU block on a r404a modded vappo PE?
Will it lower my temp mutch?
Witch cap dim and length is the best for PE ?
Witch cap dim and length is the best for Mach 2 too cooling cpu?
Witch cap dim and length is the best for Mach 2 too cooling GPU?
howe many watt is the 9800pro/XT gpu produce?
now i use a 404 mod prom at my A643200+ @2875Mhz and the 404 mod Vapo PE.
I hawe the 4. best score on the orb with 9800pro (27813p) and the fastest with 9500np. (26103p)
I have to say Ive missed this thread. ;)Quote:

hi, i have a prommy mach1 and i'm gonna mod it with r404, now it has r134a. It's the gas enough or i must change the evap too for better temps ?
sorry x my english ;)
Any new news on the enclosure?Quote:

Add 3' of .028" to the cap tube out of the drier, and recharge R-404A. Charge until the suction return temperature nears the SST when nothing is connected to the evap. Exact amount, unkown... but in similar cutom built units, around 3 - 4 oz of R404A should do the trick.
Unless you are going to cool your video card (vertical position), leave the evap the same..
Cheers!
herefishy... couldn't do me a favor could you?
On a Promi Mk II with the 3' cap tube extension and 3-4oz of gas as quoted above, what are the high and low side pressures running at no load in a 26 to 30deg Ambient??
Bearing in mind the MkII has a longer suction line than a MkI, am I correct in assuming more than 3 to 4oz of 404 is gonna be required? Just after a ball park figure based on pressures at no load to start me off with so that I can gas to slightly above that, then get appropriate temps etc from the appropriate places to finetune (which is where I'm gonna start poking at Gary and Bowman n' the crew...)
Or am I just barking down the wrong tree??!
Hi Marci!
You know, Gary is probably having a fit right now, seeing soemone aska about pressures. :p
If you go to www.austin-industrial.com/custom_jobber.htm you will see that I have a suction return temp of -42F (-41C) with and evap temp of about -57F (-50C). So with no load, nothing connected, you should see about 10C of superheat about 6" to 9" from the compressor. When you hit the 10C of superheat, then you can see what your pressure/temps are... Establishing the (unloaded) superheat will tell what the system design (evaporator) temperature is, as determined by your compressor capacity (characteristics) and cap tube (expansion device) that you have employed.
My discharge temperature would not exceed 110F (43C), I beleive. But - relative to your pressure question... I seem to recall 210 - 225 psig, but I never really gave much thought to what the pressure was - only to make sure I wasn't going to burst any pipe! LOL After I was confident that the condenser was going to handle the load, I rarely monitor or even connect to the high side of these systems to check "pressures", I just check the discharge temperature.
Hope that helps...
Cheers!
Aye I know... but need to get some gas in there to start with, and easiest way is from an idle pressure reading... specially with no refrigerant scales so talks of weights are useless to me...
Definitely useful info there d00d!! Cheers!
Generally I rough charge the Mach II to a suction pressure (with the highside guage removed) to 5 inches of vacume (0.17 bar) and allow it to run unloaded for fifteem minuets, Then I top it off to the same amount and test underload of 100W the pressure should stay the same and the temperature will rise to -50C and stabilize you can then add or remove gas in .01CC increments to taylor your charge for best temperature. If you are using R404 or don't have a highside tap you must let the unit stand for enough time to fully equilize. You cannot ever charge these with scales as the charge is smaller than that contained in your manifold set.
Aha! Now THAT's what I wanted to here... always suspected the total charge would equate to less than a fill-line / gauges worth...!
Before all of the new refrigerants came out, I used to tell service techs to paint over the pressure scales on their gauges, and just read the temperature scales. It made their job much easier. It isn't about pressures. Its about temperatures. We use the gauges to find out what the temperatures are.
Pressures are irrelevant. It's about temperatures.
Yep, I am aware gary... i've read all yer posts, however, when there's no gas in there to start with then there aren't any temps to measure. Ya need to have gas in there to be able to get some temps out of it... so charging to an approximate pressure based reading just to get gas in the system and get it running and THEN abandonin' pressures and goin off temps seems the easiest solution to me to get you with enough gas in there to play with to be able to use temp readings to tweak the amount down to the perfect charge... unless you can give me an easier one bro! In no way will pressure readings be used for the FINAL tweaked charge or to assess whether the proper charge is attained.
I fully intend to be pokin' at you with a pile o' temp readings and a big questionmark over me head once I've got some gas in there to measure the temps there-of... just to get an initial squirt o' juice in there... ideally overcharged as removin' gas is much easier for us at this end with the equipment we have than adding...
Basically what everyone's waiting for is a step by step set of instructions going from built system but empty of gas thru the adding of the gas and measuring, with photos marked with exactly where to measure... but that's always been the cloudy issue in every discussion so far...
Y'kno what I mean fella?
Anyhoo, plan so far is to plonk a loada gas in and trickle it out til it sits as it should, for which we WILL be callin on your expertise when it comes to SST, SCT etc etc...
Good grief Marci.... You just break the vacuum, and start thing up. :confused:
nevermind...
Just static charge it to 40 psi (for 404a and 507)and fire it up, you'll need to add more for good temps but that should get it running. Oh, if your only using low side fill it slowly to give it time to equilize with the high side before you start it. Then fine tune it with temps like Gary says. :D
Stick enough refrigerant in there to bring it up to positive pressure. Start it. Add enough to make it run at the low side SST you expect to end up with. Wait until the evaporator reaches its lowest temp under heavy load, then charge by best CPU temp at heaviest load.
If you are charging without load, charge to near floodback, say 10C superheat at compressor inlet. This is the maximum safe amount of refrigerant you can put in the system. You will have to remove some of it when you have heavy load on it to get optimum performance.
exactly, but if you are running unloaded at 72 degF ambient and stock captube break vac with a little fire it up and charge to 5 inch mecury or .017 barg and this will be close and may be a little over charge. then load it up and check temperatures...Quote:
