What remote oil cooler

[Marvel]

I run a 2276cc and run it hard,

got it mounted between the chassis rail and inner sill pretty much oposite the sliding door.

Alex,
Can we have a picture please, just got one of these from VWH and want confirmation of how you've fitted it.
Ta.

Here's mine:

Meant to say its a mocal with a scatt fan and oilstat. At the moment it works too well and the engine isn't coming up to temp around town...still needs a bit of fine tuning.

Just a thought based on zero experience, but it seems a big jump from standard cooling to an additional fan driven monster oil cooler?

I mean that's the oil sorted, but as Trikky pointed out, it's the heads/B&P's that are going to be the limiting factor on how hard you can drive your uprated engine so surely no point going mad cooling the oil?

Taking that into consideration, and LP's advice, I'm just having "any old" ebay cooler underneath and no fan. It's only going to get hot if I'm ragging it down the motorway when there should be plenty of breeze under the van to cool the cooler?

i am just in the process of fitting one myself. I have no issues really with cooling head temps are 150-177 C oil temps are 105-115 the latter on a hard run. I am fitting one for peice of mind when abroad. I really dont want to be away and have to sit at a crawl just cos its hot.

It doesnt need lots of cooling extra, so im fitting an extra stock cooler and oil stat. shouls be plenty and be able to keep it under control in all conditions

I'm no expert (at anything) but it isn't just about efficiency...quality matters too. I was talking to a fella at bug jam who was asking about mine. He fitted a cheap one from somewhere and it split on him...he lost most of his oil and stuffed up his new engine! Worth thinking about.

@Humphrey have you got the fan switched so it comes on at 100 C or somethin then? how many row mocal is it?

Yeah think that is the issue, probably just the wrong oilstat... it comes on at 65, think it would be better at 85 or so. But the system definitely works. Camper fully loaded, motorway cruising on a reasonably warm day used to sit around 110 C, now it never reaches 100. Think it is either 16 or 19 row but will check for you...

i have a 180f oil stat, so oil doesnt flow through the cooler until that temp, also i'll put a in line temp switch wired to a fan to kick in at 100C that way if i get stuck in traffic least ill get air to the cooler

Yeah that should work a treat.

I believe they, and some filters, split when you rev your choke free twin carbed monster to keep it going at start-up from cold? I should take more notice of the details, but apparently if you full flow your engine from the oilways rather than directly from the pump, the oil pressure relief valves in the case take care of this. Probably got that wrong, but something along those lines. I got an MGB one at LP's suggestion. It was about £25. I'll let you know if it splits but I doubt it will or he wouldn't have recommended it. :lol:

I don't have issues and but mine is only a 1745 running 8:1 comp ratio, I did wonder as Trikky says the bits that require extra cooling are the heads - I was wondering if you could rig up some high temp hose and brake duct scoops to help cool the heads? maybe with some stat controlled flaps?? routed into the bottom tin ware just above the bends?

not sure if this extra flow of air would mess up the flow from the standard fan, I think the answer surely lies in a bigger cfm fan?? I know the porsche shrouds tend to overcool...

Here is mine for my 1955cc

It kicks in at about 200f and the fan kicks in a little higher than that. It is an EMPI one (the biggest they make). It has been faultless.

Mounted between two top hat sections, LH side of the bus.

Just to throw a spanner in the works so to speak, do you need a remote cooler? I fitted a 2110 with twin 44's 2 years ago. It has full flow oil filter, a deep sump and very well sealed tin wear. I have a vdo oil temp gauge and even long journeys doing 70mph on the motorway the temp never gets beyond 103/105. Mostly on A roads it remains between 90 and 100. I was going to fit an external cooler but thought I'd give it a try without and have no intentions of doing so now especially as we don't get many hot days in the year!! What do others think?

Same story here.

I was going to fit an extra cooler but decided to see how it ran without one first. The first 100 miles it ran quite hot at up to 110C and then ran cooler and cooler as everything bedded in.

Engine makes around 120 to 130 bhp. Using a stock cooler with aftermarket full flow filter the highest temperature reached was 115C at 80mph on a Spanish motorway in summer. Go figure...

The other thing to remember is an oil cooler cools the oil. The hottest part of your engine is the cylinder heads and valves. These are cooled by air, the cooling effect of the oil on the heads is shall we say "limited" :lol:

Overheated engines fail due to piston crown and valve damage, not from seized crankshafts.

If you fit a temperature gauge make sure the thing is accurate. Ive seen some that read 20C out.

You don't say what your compression ratio is, which is critical for cylinder head temps. I have a similar spec VW Speedshop engine to you but mine runs massively hot at the moment if I cruise over 50 mph... Partly rubbish tinware I expect, but partly compression ratio. Let's not forget the oil does cool the heads too.

Here is mine. Picked it up from CB Preformance. Fan and cooler as one. It has worked money! Running a 1914cc
