Oil coolers

[MikeLTaylor]

Looked back through a few recent pages but can't see anything fairly recent but anyone fitted an oil cooler to their Sprint? If so, what is (are) the fitting options?<br>
I have just bought a Mocal 13 row cooler which is 31cm long between the fixing holes, 10cm high and 4cm wide. I had thought about fitting it alongside the rad on the driver side but the carb air hoses and fitting bracket would get in the way. Anyone with any pointers and pics if poss? Many thanks. Mike

I have seen them fitted along side the rad as you've mentioned. Mine was fitted in front of the rad but I've now relocated it to behind the number plate. Don't think you'd want to do this on a nice road car though. <!--EZCODE EMOTICON START :eek --><img src=http://www.ezboard.com/images/emoticons/eek.gif ALT=":eek"><!--EZCODE EMOTICON END--> <br>

Errr no!!! But I had thought about it - then I'd have to relocate the number plate and then worry about some protection in case any stones were thrown up into the cores. I would be reluctant to put the cooler in front of the rad as it might reduce the air flow and affect the already cautious cooling the Sprints suffer from. (Can't afford and don't want to fit a Kenlowe).

Come on you guys ! There must be more of you out there who have oil coolers fitted who could put up a few pointers ! ??<br>

im having a radtec ally rad. they do oil coolers too and all the ancillaries, and can mount the oil cooler on the side of the rad as mentioned.<br>
<br>
HOWEVER - I sell bowman oil coolers more commonly used in boat world for cooling hydraulic gearbox oil, other hydraulic system oil and also engine oil. <br>
<br>
edit - I can also get hydraulic hoses of any length made up for relatively sensible money with a variety of fitting sizes i.e. 1/4", 3/8", 1/2" bsp, 14mm, and also have a range of reducers/unions to mix n match from stock. bloody marvelous - how cool am I?!?!?! <!--EZCODE EMOTICON START :lol --><img src=http://www.ezboard.com/images/emoticons/laugh.gif ALT=":lol"><!--EZCODE EMOTICON END--> <br>
<br>
these little puppies are cylindrical in shape and various lengths depending on volume of oil, temp etc. they consist of a closed heat exchanger aka 'tube stack' in a water jacket - the cooling water obviously being the engine coolant.<br>
<br>
I've discussed the prospect of using one of these on a sprint with Mr Speedy (narrowboat vintage engine specialist geeza/sprintfire owner). Our (well more his) summary is that it would be better to use this than an air cooled cooler.<br>
<br>
Advantages:<br>
- holds the engine oil at closer to optimum temperature, which in turn means the viscosity of the oil stays near to where its designed to be.<br>
<br>
- there would be less tendancy for seasonal variations, i.e. winter vs summer, should really use lighter oil in the winter etc<br>
<br>
- more compact, easier to find a home for it<br>
<br>
- doesnt need air-flow through it to be effective, more versatile installation possibilities<br>
<br>
- bowman oil coolers are brass so would polish up a treat!!!<br>
<br>
thoughts welcome...<br>

my thoughts mr dolly boy<br>
<br>
<br>
<br>
you'd make a great sales man<!--EZCODE EMOTICON START :lol --><img src=http://www.ezboard.com/images/emoticons/laugh.gif ALT=":lol"><!--EZCODE EMOTICON END--> <br>

i can understand the theory of the bowman oil coolin rad on a boat that cannot travel more than 4 miles an hour, but on a sprint you,re only putting more strain on the water cooling side as far as i can see, or you,re adding more weight to a car that you probably trying to make lighter to go faster.<br>

am i talkin shit , i dont know?<br>

Hi Mike, reckon you only need one on a tuned dolly, and probably a race car at that.<br>
I Have'nt even got one one on my group 2 spec engine

<p></p><i></i>

[algtj]

I have seen them mounted vertically on the right hand side of the radiator....<br>
No pics I'm afraid, I am sure Scott had his mounted like this after moving it from the right hand inner wing?

[dollyboy]

Mr Rich - valid point, but water and oil resistance of these things is actually quite minimal, and as far as size and weight are concerned, bowman DC60 6" (which is all you'd need), is about 8-9" long overall and less than 2" dia, and will weigh less than an air cooled one for sure.<br>
<br>
Mr Daily Sprinter - you may not need one if your cooling system has been serviced regularly, good coolant content, fan n water pump good etc etc on a standard car, or possibly even a hot road car if you drive it like a nun, but an oil cooler of a sort would be recommended on a hot road car particularly if you have a tendancy to use it 'properly', and definitely a race car. The more £££ you've spent and the more time you've invested in making a bad ass power unit, the more worthwhile it is protecting your investment i'd say...<br>

None of my cars are driven like a nun, even the odd track day in the past too, just live too far from a track now. My everyday sprint regulary tows a heavy trailer even in this heat up some bloody big hills too.<br>
Good radiators are key to keeping temps down.<br>

Get an oil temp guage first.<br>
<br>
Mine runs a 13 row cooler that's not even in the air flow and oil temps haven't gone above 95 degrees in 25 degree ambient temps after racing for 20 mins. You should be looking at 110 degree oil temps, above that then maybe an oil cooler.<br>

Dollyboy,<br>
<br>
Provided the cooling system is up to it, I reckon an oil to water cooler is a pretty good idea, especially in applications where air flow is limited as my car is with its Civic Type R rad taking up the entire space between chassis rails. <br>
<br>
Also you dont get the worry of damaging an oil cooler and loosing your engines lifeblood very quickly over Castle Coombes black stuff.<br>
<br>
How much do you reckon for a kit? (not that I've got any cash!)<br>

fluid to fluid coolers transfer heat more effectivly than air to fluid coolers, and as dollyboy says you don't need airflow....the cons are if the cooler ruptures cross contamination of the fluids occures the fluid will flow to the lower pressure system. We use fuel cooled oil coolers on the aircraft at work...this also acts as a fuel preheater....Sorry, got bored and started to waffle....back to dollyboy!

I've been toying with the idea for a while, and whilst I think it makes sense, others may think it's "slob-lock".(anogram). I'm sure I read somewhere that most F1 teams are using them and i'm sure prodrive and ralliart offer a charge cooler kit as an upgrade to an intercooler. Surely this must say something of the virtues of this set up? Oil temp can be accurately maintained when used with a 'stat. The DC60 Kev and I have been discussing would be an easy graft into the bottom hose from the rad and would also shorten the length of oil pipes reqd'. A leak is unlikely- we use them on hydraulic gearboxes as Kev says and also on hydrostatic transmission systems, operating at pressures in excess of 350 psi, and have never had one blow. Polar ones have been known to give up tho'! I shall be trying one on the sprintfire when it eventually gets re-commisioned. <!--EZCODE EMOTICON START : --><img src=http://www.ezboard.com/images/emoticons/ohwell.gif ALT=":"><!--EZCODE EMOTICON END-->
