Thought driving around with the engine cover open was BAD for cooling, but can't remember why? Sent from my MotoG3 using Tapatalk
It isn't - though it does depend on how and what is done. I had a grey import WRC Toyota Celica with a water injection kit fitted - it was full homologated to group A and had all sorts of toys on it. Its the oxygen element that matters, not the hydrogen when it comes to engines. H2O = approx 33% oxygen. Air = approx 21% oxygen. A higher oxygen content allows for more efficiency in the fuel burnt (bit like when a blacksmith uses bellows on a fire). At altitude, where oxygen is less prevalent in the air, any form of increase in Oxygen would help the van maintain or increase its power - its one of the reasons why the Pikes Peak records will all tumble now electric cars are allowed to compete - they don't become less efficient at altitude. On rally cars, they did inject water directly in to the inlet tract as it aided cooling of the cylinders - though I have no idea how much and imagine its a far more exact science that what they purported to have in Flintoff's van - and deffo your mate's jam jar!
I think it’s because they kept calling it a camper but I reckon it only had seats; remember the rats on a stick part?
I’d imagine getting parts for one would be a bloody nightmare. I bet they come out of the factory as a right frankenstein creation.
Something like top half of engine is the cool bit. Bottom of engine below the tin & seal is the hot bit. Opening engine lid changes air flow & let's heat into the cool section. Then Warmer air is blown back over the bottom of the engine. However I doubt the top gear camper was air cooled so wouldn't apply. It's also disputed by some people who have opened engine lid & seen oil temp drop on air-cooled engine. Possibly @1973daisey on one of his summer road trips.
Yes matey bit allso I was up the Andorra mountains si was more about air flow sane as top gear Sent from my iPhone using Tapatalk
