Any pointers for getting the parts i need to make up an oil cooler for the 5VY R1 engine
Do you need one?
I've been running mine for 4 years, including thrashing it both on track and in the mountains of the south of France, without issue.
I think so, did a fair old trip on friday when it was baking hot out, engine water temp gradualy got higher than it normaly would and wouldn't cool down when on the open road. also it was becoming more and more difficult to change down the box, but it's fine again now it's cooler
As I said, I've driven in the south of France with temps in the 90's F with no problem. Places like the Col du Torini flat out in those
temps puts all the strain on the cooling system you could ever expect and certainly more than could be experienced here this weekend.
I'd have a look at you're cooling system first. Is there any way air can get past the side of your rad for instance. What rad do you have?
it does have a gap over the top, it's not massive, and it normaly runs quite cool in winter/normal uk temps around 65 - 75
but it's the oil temps i'm more worred about
What temp did you see over the weekend? Have you got an oil temp gauge?
85-90c is perfectly normal and up to 105 when stationary/slow moving, as thats the ECU fan cut in. I usualy use my manual fan switch if I see 95c as
it gets easy to stall above that. Fan held it below 90c when stuck in Genoa traffic for a hour with ambient approching 40c. In winter mine runs around
75c..ish.
Any gap around the rad won't help. Do you have sufficient venting for the hot air to escape? That can make a difference. Is the standard oil
cooler piped into the rad top hose or the bottom? It'll cool better in the top. It should keep the oil temp to not much above water temp.
Have you checked your fan direction? It wouldn't be the first to spin the wrong way.

i've not got an oil temp sensor, my fan cuts in at 100, maybe a calibration issue between my coolant temp sensor and ecu sensor, but it does cool it down to 90 ish before the fans stop again, i'm using the 2 r1 fans that belong on the bike, and they are going the correct way. i think the oil cooler is plumbed into the bottom pipe but i'd have to double check that. as for vents i've got one in the side, that's blown with another R1 fan, engine bays closed in from the front to the forward part of the engine, and i've added the mnr diffuser, which more or less blocks off the tunnel at the back of the car
my 5vy had its first track outing at oulton yesterday. i need to sort out the cooling as even with a cheap 10 row oil cooler 15 minutes on track was
my max. by then oil temps were 125.
in the afternoon i started to get water temp alarms as well, 15 minutes would see it getting over 110. both temps dropped down again pretty quickly
when i backed of.
was a very hot day and very still. my next move i think is to look into the best way of letting hot air out and probably fit a bigger cooler.
i got the sandwhich plate from andy bates, http://www.abperformance.co.uk/
does need a bit of modification to the coolant pipe next to it, http://www.austengreenway.co.uk/2011_02_01_archive.html
pipes from think auto and got given the cooler as it wouldn't fit a mates mini.
Hi
We have an R1 2000 carbs
independently wired , see waterworks layout in our photo archive
This works fine on ours.
good luck.

was discussing it with andy bates on friday, he also suggested that the standard polo rad was marginal for hard track use. quite expensive for a
decent one though.
i've also got a suspicion that the car is running a bit lean which obviously wont help temps so need to get it back on the dyno before i go any
further.

there's not much spare room either side of the standard one in the striker. andy's solution was an alloy version of the polo rad but at £260
is a last try option.
been comparing oil coolers, my 10 row is size wise in height about half way between the mocal 16 row and 19 row coolers. thinking about getting the 19
row cooler as it will be easy to alter my brackets 10mm and i would of thought 19 rows will give much more surface area for cooling over 10 rows.
I have a 19 row (IIRC) Radtec oil cooler for sale. It needs a flush (previous engine munched a bearing) but is otherwise in good nick. £50.
Will have the 10 row if you decide on a bigger one. Cash waiting
ok.
have you got it started yet?
65-75 is too cool id say, you want it running more 85-95. off the top of my head, the fuel enrichment cycle only comes off at 76 degrees.
Oh, and if you add a diffuser you want a slight gap, or some means of venting otherwise you get a hot diff.
