Ark Posted June 28, 2011 Share Posted June 28, 2011 Hello Everyone, Just toying with ideas for tinkering with my oil cooling...thinking of daisy-chaining a second cooler on the other side of the car. Obviously the easy solution would be braided hoses, but they might have to be routed low, behind the radiator. So, I was thinking of using hard pipes similarly sized to a -10 hose, to make them safer from road debris. Would 15mm domestic copper pipe be adequate for this? Can this be joined to JIC hose ends, perhaps via a BSP convertor? I figure that the heat conductivity of copper would also help dump heat from the oil, as well as being nice and cheap.

Scott Posted June 28, 2011 Share Posted June 28, 2011 It sounds great in theory (with the extra cooling etc) but I would be a little worried about said road debris hitting a copper line. The braided oil lines can take a LOT of punishment, I'm not so sure a copper line would be up to the same sort of beating. Also, imagine the copper variety being crimped somehow, or even dented by slightly larger debris. I would be worried about it being restricted.

SimonB Posted June 28, 2011 Share Posted June 28, 2011 Think I'd be more worried about the joints and whether they would stand up to 120psi or more of oil pressure. Braided hoses would be much easier to route too. Plus they should be protected by the undertray anyway. Quote Link to comment Share on other sites More sharing options...
Ark Posted June 29, 2011 Author Share Posted June 29, 2011 ...if my undertray hadn't ripped and been removed... Good comments, thanks guys. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 29, 2011 Share Posted June 29, 2011 Go braided with proper AN fittings. Do you NEED more oil cooling though? Quote Link to comment Share on other sites More sharing options...
Ark Posted June 29, 2011 Author Share Posted June 29, 2011 Possibly not - but it gets a bit warm in there on trackdays (like 130 degrees for oil, 105 degrees for water ), since I fitted the FMIC. Stupid thing to do in retrospect, but we are where we are. I'll be damned if I'm removing a grands worth of intercooler when I've got a spare oil cooler kicking around. What else could I do to drop heat? Would a full decat help? Ducting? Single turbo, rather than two turbos heating the fluids up? Quote Link to comment Share on other sites More sharing options...
bignum Posted June 29, 2011 Share Posted June 29, 2011 What size is your existing oil cooler, a 19 row will normally surfice. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 29, 2011 Share Posted June 29, 2011 For best power water wants to be about 85 C. Drop the water temp and the oil temp should drop in unison, due to the stock oil to water heat exchanger. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted June 29, 2011 Share Posted June 29, 2011 Where is your oil cooler situated? and what size? Quote Link to comment Share on other sites More sharing options...
SimonB Posted June 29, 2011 Share Posted June 29, 2011 Duct the intercooler properly if it isn't already and get hold of an undertray would improve things definitely. Quote Link to comment Share on other sites More sharing options...

Ark Posted June 29, 2011 Author Share Posted June 29, 2011 (edited) I can't remember how many rows it is, maybe 25, BUT it is a narrow one to fit around the intercooler pipe as it comes through the nearside vent. Currently it's un-ducted which is my first port of call. Don't get me wrong, on a cruise or hard drive, the temps are fine. It's just when I do a long session on track going really hard that it gets hot. That's when the cooling system can't really cope, and I'd rather end my session because I'VE had enough, rather than because the car has! Would ducting the intercooler really help? If air can escape around it, then I get cooler air into the radiator, surely. So it's the radiator that would need properly sealing against the frame.

Got a metal-shop fabricating a new undertray for me...it's taking them ages, so it must be good!!

Ark Posted June 29, 2011 Author Share Posted June 29, 2011 here you go mate try this http://www.speedflowshop.co.uk/hardline-system-150-c.asp Thanks buddy - that's exactly the kind of thing I was looking for...until people started talking me out of it! I'll save the link for later though. Quote Link to comment Share on other sites More sharing options...
SimonB Posted June 29, 2011 Share Posted June 29, 2011 Yes, for engine cooling you want to make sure that air can't escape between the bumper opening before going through the rad. So if you have a gap underneath between the fmic and rad a lot of air will escape down there rather than go through the rad. Same goes at the sides and the top since you normally have to remove the stock ducting there. You're probably right that if the fmic wasn't ducted to the rad you would just get air bypassing the fmic and then going through the rad anyway, but only if there is nowhere for it to escape first. Not much point in having a fmic and having air bypassing it anyway of course! Quote Link to comment Share on other sites More sharing options...
