looking good mate, bet you cant wait till they map it and you get the results and get to pick the car up

 

 

cool fingers crossed

 

 

Just read all this after talking to you on Facebook. And buying the dv.
Look forward to seeing the results 👌

 

 

isn't that oil cooler going to just empty into the sump soon as you switch the engine off and have to refill again after or does the sandwich plate sort that out as iv always mounted them upright for this reason ?

 

As it runs a thermostatic take off plate, it opens like a coolant stat, so doesnt open til upto temp and then closes when at temp.... the feed is also at the bottom of the core and circulates UP to the top so no it wouldnt empty. Also bare in mind it works on oil presure, temp and flow regardless of where its mounted anyway.

 

thanks for clearing it up ,, just my concerns about it being open when you shut off the engine as liquid will always try and find the lowest point ,if it shuts when up to temp what stops it getting hotter ??,, just the reason iv always mounted them upright but as long as its safe I don't suppose it matters

 

You can mount the core any way you wish, even with the take offs at the bottom if you wanted, as oil is under pressure if is pushed around the core anyway so it finds its own and doesn't need bleeding like a rad. It wont cause any negative effect which way you fit it TBH, although iv heard people say the way you done yours can cause a build up of hot oil (like a bath) in the core as it doesn't flow as effectively as when its top to bottom, but like most things online, its probley bollocks anyway lol

 

yes but the pressure stops with the engine as it comes from the pump so my concern was that with the stat open due to being up to temp and then turning it off the oil would want to find its way to the lowest point and wouldn't have anything stopping it as the stat would be open and due to being up to temp and the engine wouldn't be running the pump to provide pressure so until the stat gets cold enough to shut whats keeping the oil in the cooler ?

 

That is true, but the oil doesn't need to be in the cooler when you start the engine, it needs to be in the sump, so it "draining back" is better for the crank bearings, then when the stat opens it feeds the core again to circulate the warm oil around....

Anyway lets not shy away from Raggy Doos thread... sorry bud

 

 

ooh, getting close now!

 

 

last post and then we can pm if needed save messing up the thread lol, and I enjoy debating these things sensibly for a change ,, but you would then have too much oil (possibly a extra 1tr) in the sump until the stat opens and that can't be good for a engine

just my thoughts on it but if laggy is happy then thats the only person that counts

 

The thermostatic element redirects oil flow. The bypass is fully closed at the stated temp, diverting the oil through the cooler.

 

 

I would suspect the manufacturer, in this case perrin, know a darn sight more than anyone on here wouldn't you say, you could take it up with them of course

 

I believe that is correct yes, it sits open during "below temp" then when up to temp it blocks the flow so the oil is forced round the core. That obviously means that theres not a litre extra as domino suggested before.

Tidgy also makes a good point, perrins kits come upright, so that's how they state to fit aswell...

 

All mickey taking aside, hownwould you fully drain the oil during changes if you didn't have a downward flow?

after a quick nosey round at fitment on various websites and such, the general consensus is it doesnt really matter. Some seem to fit both feeds down, some both feeds up, some side feeds.

 

 

The Perrin stuff should look good for the price! Perrin tax

 

 

looking sexy mate

 

 

Looks great, let's hope it's not smashed through pot holes on the test drive

 

 

I have to say the workmanship looks top notch.
you've done well to persist with the car.
Top marks to the clinic for trying to sort it out ,hope it ends with a working sorted motor
