PWR Barrel Charge Cooler idea - Someone's done it - pg3

[Protok]

You still haven't fitted that Vinny?

Mark have you thought of the ebay copy ones?

[shinny]

Sorry mate its a 5"x6"

Both inlet and outlet are 50mm OD

Intriguing - that doesn't appear to be the product that's available anymore. The smaller inlets probably help increase the length compared to the 5"x6" version listed on the website. Don't suppose you can take a tape-measure to it quickly, just out of curiosity?

eBay copies? Never seen them - got a link?

The compressor is easily rotated if needed. Are the inlet/outlet a bit of a bottle neck being that small?

I was trying to look that up the other night... it it easily done on the CT20b while it's still on the engine? Cos that would make life ALOT easier if I plump for the 5"x8" core!

Total length of it is 335mm

To what dude? My mk3 has no engine any more

Mark the copy ones are on ebay usa mate http://www.ebay.com/sch/i.html?_trksid= ... &_from=R40

Ah, yes... the box shaped ones aren't true counter-current cores and are just air-to-air coolers boxed up. The true barrel ones are more tempting, but aren't listed in the size I'd be after

Do you have a rear strut brace? Cuz this one wont fit under my TRD one in that position

I have a stock X brace and I think it will miss. Provided I can get the outlet close enough to the throttle body itself (closer than you have it in your picture), I think the main bulk of the core will sit behind the X itself, meaning just the smaller inlet and hose needs to nestle under the brace itself. I could of course be wrong, but I've got another scaled photo on my laptop at home showing the bay with an X-brace and the core sitting behind it.

Either way, to move forward with the idea will be a bit of a gamble / an expensive experiment. This thread make me think it'll just about work - and if the brace gets in the way, it's an excuse to get an Ultra Racing brace back there: http://www.ultraracing.my/catalog/index ... er=product

Shame you aren't closer to me, you could have borrowed my core for experimental purposes

what ever they are, they gave me next to no intake temp increase on 1.4bar of boost to redline.
ran perfectly well on my old setup, and still does.

thats not to say the barrel ones arnt decent, just that the ebay boxy cores were perfectly capable of keeping my temps very low, and they have supported 800+hp over in the states.

There you go

Some guys in the States swear by them.

EDIT: Jim beat me to it

im prob bit behind with the times but i dont remember any running the barrel type copies over there, just the huge box shapes ones. but they may run those also for low levels. i havent popped over there in a while.

[shinny]

I can understand the attraction of the huge cores - they may not be the most efficient, but they're so huge it doesn't matter.

However, I was looking to minimise lag in the same way the ST205CC does, by keeping the pipework as short as possible. These barrel core not only allow that, but keep the air going much straighter than the GT4's cooler. Obviously I'd need a smaller core for that, so efficiency in design becomes alot more important. Therefore the inefficiencies of something like this kinda put me off:

I'm not saying it won't do a job, but I think the barrels will be more efficient (with true counter-current flow) and look much better too. If there was a 5" diameter copy then I'd consider that, for sure, but so far all I've seen are 4" diameter copies:

will those cores fit under the engine lid when in place? especially if running engine lid fans? given the thickness it looks to be very tight. to the point that it would nearly be touching the hot cam cover, so aborbing all that heat, and hitting the lid.

tho straight seems more sensible, it would also concern me that it rushes through so fast without being cooled, if that makes any sense.
an extra foot or 2 of pipwork will hardly create any noticable lag, if any at all depending on the amount of bends. be hard pushed to notice especially on a stock turbo imo.
if going for a barrel, i would as you say go for something decent, the ebay square cores are so large it doesnt matter.
