Finally got my car sorted last week by castle performance, its running great. The only problem is that when i'm cruising on the motorway the engines starts getting warm. I have to drive with the fans permently turned on and on some occasions with the cabin heat on full trying to stop the engine getting to hot.

When i've got time i'm gonna try flushing the coolant system out, rad and engine block.

I was wondering if anyone else is having or had this problem, if so what did you do to cure it. The cars drivable on normal road and you can have a proper play without any problems, its just when your cruising at high speeds (not silly speeds) on the Mway.

By the way, the car was having this problem before i got it set up. Just forgot to ask at castle when i was there.

Thanks for any advice
