    So how does this work? I thought you removed it so there is always oil going into the cooler.

    By blanking it off it sounds like no oil would be going to the cooler. Which will of course not be the case. Or is something else bing blocked off?

    Isn't there a different temp stat available?

    Once the stat opens, all oil is flowing through the cooler. So what is the diference between that and having it run through the cooler from the get-to?

    Apart from the oil taking longer to heat up?

    There is no replacement stat, and it does not open as fully as it could as such a lot of oil passes directly back to the block rather than through the cooler.

    Removing it leaves a void that would mean the flow was not correct, putting in the blank keeps the correct flow but does not restrict the flow to the cooler.

    Ok that explains it.

    Sounds like a design error if oil can flow back into the block instead of passing through the cooler.

    no, its just a way for the oil to return when the engine is in warm up.

    Wow, what a difference, Snetterton today in 30 degrees. Full on 30 minute sessions and never once went above 100 degrees. Super pleased

    Yes mate it was. Had a blast. Reckon if I picked up some slicks I may have been able to stay with you. Your two cars went round corners like they were in rails. What camber you running up front on track?

    Excellent. Great to meet you pal, your car is a rocket, looks lovely too.
    These are the geo settings I had when it was on 17’s

    So, 3 degrees of camber but I reckon 4 degrees would be better. I have the same settings with the new set up which gives a good balance as you saw! I think I will add another degree to the front before I go to the track again :thumbsup:
