Moving my 1990 GT oil cooler.

It becomes a problem in stop-start freeway driving in the L.A. basin in the summer. Which I try never to do, but occasionally get caught in. You can sit and watch the oil pressure nudge downward. I am adding a virtual oil temp gauge into the flush console build so I can get a better feel for oil temps under various driving conditions. (I have a set of these hoses but pathetically have not yet installed them...)
I'm also going to add an oil temp gauge. The more I understand oil, the more I understand the importance of its working temp range.
This is a bit eye opening. Well for me anyway:

Appreciate if you would.
I am deeply suspicious of that cooler arrangement and worse, I noted a bit of dent on the frame of mine- heavens know how that happened.
I purchased an after market cooler [photo attached] with an integral fan mounted on it and a SPAL programmable controller and wiring harness kits- just never got round to mounting- mostly because it seemed rather complicated. The cooler can fit in the front driver side [LHD] wheel arch although whether it would fit with the puller fan mounted is another matter. not a good place to mount a piece of electrical kit if it does rain [not very often here].

This pic is of Installation Mark 1 (now nla., so ignore the awful metalwork). It's a Mocol 19 row cooler with the same cooling capacity as the oem GT cooler.
Nothing under there is straight or parallel and it's all hard to reach. Grrrr. Plus I badly misjudged the space needed for the sweep of hoses on to the fittings etc.
Have to navigate a location between the retracted headlight, the guard and the vertical separator panel up to the abs unit.
Installation Mark 2 planning is done but not executed. This week maybe.
As for water on the fan electrics: I shouldn't worry; with the guard liner and chin spoiler fitted it would be almost the driest place in the car.
Cheers.

My thinking was that when fitted, the air has to have a good flow path into the matrix and a good exit path [the wheel well] thus the [possibile?] concern of water ingress through any modifications to the wheel well cover.

Thanks for posting- should be a neat installation. Will you have to make baffles to ensure the air blast hits the cooler matrix rather than bypass it?

Makes sense to duct it that way. The best pickup for the air is probably a bit lower and further in front than the main headlight opening, but that's pretty good, too.

That is exactly the type of mount I had in mind for my cooler project- what exactly are you cooling? - presumably the intercooler circuit?
The cooler is very similar or identical to the one I posted a pic of earlier in this thread.

Quite a few people (myself included) have the dual serial cooler arrangement: late stock air/oil and also the earlier oil/water radiator side tank cooler. Makes a huge difference in mid-summer stop & go traffic - especially if that comes after a sustained high speed run...
Oil choices make a difference to temperature sensitivity too. Switching from Mobil1 15W50 to AMSoil Z-Rod 20W50 made a large difference to hot oil pressures even before the dual coolers were fitted.

I trawl the net for hours and often find things by accident. IIRC this came from a bodywork aerodynamics site. That was before the hdd crash that lost the bookmarks.
I have a few things going at the moment, other than Shark work, that have me trawling the net:
- BMW R1100S sports bike: aero stuff, ecu re-mapping (not by me), and surprise surprise - oil cooler problems. Vot izz it viz zeese jermanz eh?
- 1982 Honda Goldwing revival.
- 1971 Honda CB750K: head conversion from 6.5mm valves to 5mm valves + port cleanup.

i remember stuffing one of those on a long sweeping bend outside a big pub popular with riders of Brit motorcycles on the Isle of Man back in 1973.
Apparently there was some kind of Triumph Owners Club convention going on with hundreds of Brit bike there and when I pounced the rice burner on my 650cc BSA Rocket Gold star- apparently the punters went absolutely ballistic [according to a friend who was present on his Bonneville and recognised my somewhat distinctive fully faired machine and its megaphones].
I could not accelerate like the big Honda [awesome performance for its day] but on the fast twisties it was a different proposition altogether with the Jap Crap rubber frames causing their owners **** retentive issues.

Ah good old days- the bike
