Mach II Modded

**LittleDevil** · 10-20-2006, 08:35 AM

I decided that i will make SS in one of Mach cases. Today i got it back from painting, tomorrow i will braze new evap and suction line for it.
I will use original mach condensor + desuperheater and little stronger fan on it. I also make little hole for on/off switch on the back side of the case, because i will not use original mach controler.

Here are some pics:

thanks

Brazed condensor...

Power on/off switch.

thanks

looks nice and clean as usually.

what's the plans for this? a customers unit?

any special features coming up on this unit?
gas? 507 as standard those days?

**LittleDevil** · 10-20-2006, 02:13 PM

Gas will be R402a.

what's the plans for this? a customers unit?

It isn't sold yet, need to finished it and than i will put it on Sale Thread

thanks

Oh, I love it. Clean and easy - hoping for nice temps at all........

BTW, why do You did not use a double sizes condesor......, might bring some positive effect.

**Nosfer@tu** · 10-20-2006, 03:57 PM

Looking forward to temps

Problem is, Dont have anything to compare to

**LittleDevil** · 10-20-2006, 10:50 PM

Problem is, Dont have anything to compare to

Original Mach 2 has about 10 - 15c higher temps on load.

thanks

Nice

You're making this Mach into what it really should have been in the first place. Clean and powerful.

I've been doing the 'original condensor with desuperheater' for a while now and other than the very best aftermarket condensors I haven't found much difference.

It's a shame to have to up the fan power (and noise) but these condensors REALLY perform with extra fan power.

As for comparisons, I don't think there will be ANY comparisons when it's done

FYI:

Original Mach II 134a - -10 to -15 at 150w

Mach II GT 404a Unmodded - -20 to -25 at 150w

Mach II with upgraded Evap - -35 to -45 depending on gas

Knowing LD's work, it's much more likely to be closer to -45 at that load

Nice work, looks very clean.

Shame that there's no controller, but considering all the problems with Asus Conroe boards lately, maybe that's not a bad idea

Cheers

Gray Mole thanks. Original controler is only for ''nice looking'' Here you can see compared temps, original mach thermal probe (controler) and k-type.

Here are new pics...

Brazed evap with suction line.

Almost finised

**LittleDevil** · 10-21-2006, 03:52 AM

Pressure testing now... Than i will try how much difference is between temp if you put k-type on the top of evap (suction hose) or if you put it on the side of evap.

That's a good idea. I doubt it will be a huge difference, but it's something I've been curious about but never have enough time to check on every unit

Controllers aren't always needed, and really for a benching system all you need to know is what temp for booting and that it's holding the load, and a K-Probe does that just fine.

I've got a couple of chassis sitting around here myself and when I get around to putting them back together I'll be painting them up nice too. It really looks great

nicest dd units made in europe there littledevil. your work is without comparison. drool, drool, slurp.

**fatty** · 10-21-2006, 07:23 AM

Very nice sweet looking unit

I have a few spare chassis kicking around too

**LittleDevil** · 10-21-2006, 12:58 PM

Thanks guys

Here are some temps, tomorrow testing for load

thanks

**thunderstruck!** · 10-21-2006, 01:03 PM

Your units always look so clean. Very nice stuff. What do you do for a living if I can ask?

**n00b 0f l337** · 10-21-2006, 01:39 PM

Can't wait to see the load, tuning for what? Like 165 watts?

symphy · 10-21-2006, 01:51 PM

-52 degrees measured exactly... what is the mach display showing

?

Difference between display and correct value seems to be larger i ever thought... but i'm not building units

Very nice and clean looking work you did there...

**LukeXE** · 10-21-2006, 01:52 PM

I tested that, one temp probe on side of evap, and second one on suction line 1cm from evap.

On suction line I`ve got about 10*C lower temps than on side of evap, quick test, must do more

**n00b 0f l337** · 10-21-2006, 02:36 PM

By the way I dont see a probe on your evap, is it on the back of the evap or something? That can't be that accurate.

I've also seen the same 10C Luke, thats why I do a drop of thermal paste on the lower side and then tape it on.

**kayl** · 10-21-2006, 04:38 PM

nice build there little devil,
for load testing can we see 1hour of SP2004 Orthos.
personally this generates the most heat love to see what temps ya get on your conroe

**Brettbeck** · 10-22-2006, 01:07 AM

Great work!

But I don't see a high side access valve? Do you not use one?

**LukeXE** · 10-22-2006, 01:27 AM

Brett, no need for it

**LittleDevil** · 10-22-2006, 01:37 AM

Hehe 10c

IDLE:
evap: -52,3°c
suction: -52,4c

LOAD:
evap: -43,1°c
suction: -44,2°c

thanks
