Hi All
 I've been lurking in the back ground for a few months now, and I must
 congratulate you all. Its good to see so many like minded people
 sharing experience. At the moment I have been working on my 13B turbo
 S5, finally starting to look like something from an aircraft. I'm
 building an RV7 QB it should be shipped from vans early next month.
 I'm an aircraft sheetie with Qantas airlines down here in OZ, so
 progress on empenage was quick, (2 weeks to complete ). Having my
 manifold welded at the moment, water pump next witch leeds me to my
 question that I hope someone can answer. The gallery that connects
 the inlet and outlet inside the water pump casting just below the
 thermostat, should this be blocked if not running a thermostat. I
 could be wrong and probably are but with this open wouldn't the water
 take the route of least resistance and recirculate back through the
 engine. By the way I work just a few minutes from ATS Turbonetics and
 will be taking to them soon to mod the turbo so ill let you know what
 they say. Cheers.
 Mick. ( go for gold aussies)
