Mine has no louvers, wish it did.

Hello, everyone

Many thanks for the help!
In the link you can find photos and drawings, if you are interested

CraigL, it gets quite toasty under the bonnet. The oil tank picks up heat and has no place to radiate it out but to the captured air under there. I was thinking that even a small passive radiator for the oil on the front end would be nice.

Looks a neat instal, so the bracket is to move the regulator up rather than out to give clearance for the sender?
Is 15.3 psi at 105.3 c your idle pressure or are you setting up the high and low warnings on the gauge? Perhaps we should have a post your oil pressure thread for those with the SPA gauge🤔

When I measure engine oil temps in the return line from the engine and then measure the tank oil temperature i get about a 10 degree F lower temp in the tank until i have been running on a warm day for an hour and then the tank oil and the engine oil are the same temps.

So in my case with a regulated oil cooler system i can keep the oil temps to 183F max so therefore that is the temperature being radiated under the bonnet. Louvers or a grill in the bonnet might lower the temps under there but I have no clue as to how much.

Thanks for the drawing details of the changes to the rectifier mounting plate PMB, I just hacked mine about until it cleared but it's nice to have some proper dimensions to work to. I will add it to the SPA oil pressure and temperature gauge fitting info if that is OK with you? The alternative is to re-locate the rectifier to the rear bulkhead, as Phil Bleazey has done, which probably simplifies matters even more.

I think you need to get the oil temp up around 100c occasionally to boil off the moisture, keeping it too cool can be as bad as too hot.

Hello together

@Obie:
Thank you very much. I have put another scan in the Dropbox, then you can see the changes better. Placement at the top remains the same, only the connection to the lower attachment has been optimised. I have set the warning lights to 107 degrees and 15 PSI. The higher the temperature and the lower the rpm, the lower the pressure, but I was shocked myself! It was also very hot and a lot of stop and go... Normally the temperature is around 90 degrees...

@Planenut: Of course you can use all the information! If you print the drawings 1:1 they are to scale. Unfortunately I could not upload the documents to the forum.

You've got 1 psi more than me so wouldn't be too concerned and 105c in hot stop and go traffic is nothing to worry about also.
