rad and air flow
Now I have the engine running fine I am looking at ways to increase air flow, I have cut a hole at the bottom of the nose cone and I am making some
aluminium deflctors to feed the air direct to the oil cooler. This way the oil cooler has a direct fow of air, the only problem is it wil get no flow
from the fan when stationary, Is it a good idea to increase rad size and leave the oil cooler as desccribed?? I have basicaly split the nose cone into
2 separate compartments with deflectors, If the fan cools the water will the oil temp drop without a fan??? out of the 2 what should I concentrate
more on?? im stuck on this one...........

Air flow to the oil cooler is not as crucial. When you think about it, the oil will get the most heat input when the engine is being worked hard, so
it will get sufficient airflow then without the fan. An oil cooler is only an auxilliary cooling method to the radiator - many are mounted under the
oil filter assembly (my V6 for example) and there isn't too much air flowing around there!
If you improve the rad cooling efficiency you also improve the oil cooling too.

Agreed, oil temps are only going to get high when you're caning it so I wouldnt worry about flow from the fan. If you think about it, many
people get away without an oil cooler at all yet their oil doesnt overheat in traffic.
From what Ive read, the most efficient way of doing it in a confined space like a Locost nose is to have the water radiator as big as possible to fill
the hole, then mount the oil cooler in front, hard up against the water radiator.
As long as there's no significant gap between the two rads, the airflow through them both will still be pretty good, so the part of the water
rad behind the oil cooler will still have a positive effect.

Concentrate on the water rad, and also what happens to the airflow in traffic...
Does the air circulate around the sides on the rad back to the front rather than draw in cool air?
Opinions are like backsides..
Everyone has one, nobody wants to hear it and only other peoples stink!
