ABSOLUTELY NOT, IF the oil temperature is not REGULARLY exceeding 115-120°C!

You want the temperature to hit around 110°C on track, as this will burn off any excess water that you get in the engine from the heating / cooling proces, so if it is around this in hard use, then spot on . The standard Cossie set-up is pretty good and takes some serious abuse / power to exceed these temps.

You would be better off fitting a big wing sump for extra capacity, as the 3.75 litres of a standard 4x4 sump is pretty marginal . This will improve cooling due to the increased capacity, as well as the additional benefit of having a sufficient amount of oil for an engine at this level of power (plus helping with any surge issues).

So to answer your question, first I would measure your oil temps and then if you were concerned, then I would fit a big wing sump - the oil cooler would be a last resort. I am now only having to fit one on my car, as it is only with the new engine that temps have gone over 120°C on track.....

FYI a good oil such as the Silkolene ProS 10w50 does not break down until 130°C.....

 

ive suffered with 115c temps and killing the oil was going to go with a wide sump to try to combat it if not a oil cooler will be fitted

 

If you're killing the oil at 115°C, then something is wrong with the oil .

 

Even my old xr4i used to hit 130C

mine runs at 100 tops just dont see the need for the cooler to be fitted to mine ,as mike said the oil will be kept to cool if you do!

worth watching the temps with als though

 

lol

 

my big wing wing sump is great i love it,great mod

designed and crafted by ava at a very good price

 

As Mike says, measure it and then that will make the decision for you.
