I've been having heaps of fun giving the beetle a good thrashing on most weekends. On long runs it has been running hot, however this could be a combination of mixture and timing. I have decided to add an external cooler though for some piece of mind. The fan will be switched so once the temp gets to a certain range, I can flick it on/off manually (could have run a thermostat/bypass but for now this will suffice).
Hopefully over the next few days the plumbing will be done then I can get the engine back in to see if it makes a difference! I am glad I made the rear apron removable!
Cheers
Alan
