HI all.  Doing some research on a trans cooler for my T400.  I know (believe) that Drivetech do a good cooler but they are not cheap, not that price will necessarily sway me. However most of their coolers with fittings (as opposed to barbs) are reasonably thick 4-5cm.  I've found a business in Sydney 247 Prformance Fittings that sell one on EBay under the name performanceandparts, (sorry can't copy the link) which is a good size and without the fittings etc is reasonably priced and was wondering if anyone knows them, has had dealings with them and/or used one of their coolers. Alternatively what have others used.  Additional question, where have people run the lines through the rad. support when mounting in front of the radiator, or in my case in front of the aircon condenser in front of rad.  Not really interested in looking at a remote location unit. Thanks in advance.  Cheers Ron

I bought one in Sydney for my HK. Will get you a picture and where it came from.

[dattoman]

What size you after ?

Is there a drivetech reference ?

I deal with them every day

[yel327]

Bought this from Motorsport connections in Sydney. Look like AN6 fittings. Aussie made PRW

Thanks gents.

 

Neil, the Sydney one on EBay is 280 X 255 x 19mm. The size of the one Yel has bought is about what I'm after (size of A4 piece of paper)

The Drivetech one is P/N 0555-331918-4.  I've sent them an email asking for the info and suspect the width is 4-5cm which is what I may have the problem with.

 

Yel thanks.  I had looked at PWR and was going to look a bit closer at them when this one in Sydney popped up.

 

I think I will fit-up the nose cone and the bonnet release bracket and see exactly how much room I have.  Cheers Ron

I think Motorsport connections was in Castle Hill. I dropped in there to buy brake line, flaring and bending tools and saw this on the wall and realised it was Aussie made PWR. So they keep them in stock. I just found the receipt, was $150 plus GST. Pretty sure PWR part number is PWO0530, 280x200x19-6AN. About $150+postage, although you’ll pickup the ones with barb fittings for $25 cheaper.

20,500 BTU is what I've been told to use for 5k stally trimatic & 3k stally 4l60e

 

B&M 70266 or same item through Motospecs under Drivetech brand at cheaper price apparently Pt no. 0555 331017

[yel327]

Mine is a TH350 in a 1400kg HK. Originally was using a B&M Holeshot 3000 but I think I'll scrap the B&M converter and get a 4L60 converter modified for around 2800rpm stall for the TH350C that will go in with the new motor. I'm planning on 3:1 gears maybe 3.25 later hence the 2800 rather than 3000 stall. Mind may change later though as the TH350C has a lockup converter thus highway speed, stall and diff ratio no longer really matter with the lockup converter.

 

Crow told me the 3000 was a fraction to high for the cam I wish to run as well.

 

I plan to mount this cooler front and centre in front of the A/C condenser. If I have to I'll run two of them.

[gtrboyy]

If convertor done properly it won't slip at light throttle applicatications like cheap shite convertors.

 

4.5k stally in sle had a minor slip down low 1600-2000 then behaved like stocky...stand on it straight to 4400rpm flash stall

 

3k stally going in vp is for almost stock baby cam 304.Not sure if I'll try 3.45 gears 26" tyre or just go 4.11 27" tyre although was told could easily use 3.5k stall but wanted it lower if go vortech route or more likely stroker.

 

Got 4l60e convertor through HQ 368 (Mark) off AV8...trans guru.Has better gear in it than B&M etc items for decent price & delivered up here.

 

Accelerator Convertors is who built it & couple of big name trans builders up here use them so made decision easier.Big backlog if try to order yourself & to make sure it got all right bits went through Mark.

 

Iirc think he said should use 2 of the transcoolers if they'll fit as where I'm at lot of peak hour traffic & 50 km/h zones

[yel327]

Yes, the B&M was always going to be a slippy POS. I will get the trans done by Als I think, will get him to get the converter for me.

[gtrboyy]

Shift Right up in Richmond is good too.

[yel327]

The TH350M is at friend’s in Vic atm. When I get down to Vic I’ll drop it to Al and get him to build it. He may use Mark for converters, not sure.

Thanks Neil.  Will try and get some more measurements on space and take it from there.  That is once I get back to the Torana after having to restore the Ark here in Melbourne, and the temp. decides to hit double figures which isn't likely today.  Cheers Ron

Hi all.  The next question in my quest for knowledge.  Is a painted/powder coated cooler less effective than a raw metal cooler.  I presume the answer is yes but is it significant enough to steer away from them?  Cheers Ron

[yel327]

Paint is not what determines the heat that a surface can dissipate. It is the surface area and the emissivity of the surface. A glossy or shiny surface is far worse in getting rid of heat than a dull/matt surface. So painted in matt black it will get rid of heat far better than a shiny alloy surface.

Hi all.  FWIW I have just ordered a PWR cooler. PWO0530 which is 280 X 200 X 19mm. with 6AN fittings.  I went a bit narrower than the 230mm one as I wanted to make sure there was no interference with the bonnet catch bracket, bearing in mind I have an aircon condenser in there as well.  They will powder coat it and delivered to me (QLD to Vic) for $184 all up, which I think is reasonable.  Hope they can get it over the State lines. Cheers Ron

Is the sheen related to getting rid of heat or absorption of secondary heat source?  

Asking the question to learn, not to challenge.

[yel327]

Google: Thermal Emissivity. It is a measure of a surface’s effectiveness in emitting thermal energy. The co-efficient for it varies between 0 and 1 with 1 being the best emitter of heat, which is perfect black body radiation. Read the first paragraph of the Wiki page that comes up, and scroll down to the page to the table of common surfaces. The easiest ones to comprehend are Aluminium foil (shiny) vs anodised Aluminium (duller) and polished Copper vs oxidised Copper. Then look at paint too.

The other consideration is surface area. For example you’d think a bare copper bar would get rid of heat better than the same bar with a 2mm thick layer of insulation over it. But it doesn’t as the insulated bar has a larger surface area and the formula is based upon the surface area.

Some more stuff on different surfaces below:

[hatchssv8]

Yep. agree.

i got somewhat confused with glossy v matt description.

thanks YEL

[claysummers]

The best emitters of heat are also by definition the best absorbers, and vice versa. Alloy radiator will dissipate heat more efficiently with a thin matte black finish. Black anodised would be good. A thick coating of black enamel woul$ have to h@ve some insulting effect? Emphirical data required.
