This is cosmic man!! Last wek i installed a rough and ready hot air intake to see how it works. I reversed the end of my intake to face the engine, then duct taped a length of flexible aluminium duct onto it and wedged the end behind the catalytic converter. I zip-tied a temp probe to the inlet hose just before the inlet manifold and wrapped it in some lagging to reduce the influence of the engine bay heat. Its hot in there! It seems i'm getting an inlet temp of 60 deg celsius but i'm dubious of the probe reading the heat off the inlet pipe. I'll drill a small hole and have it in the air stream and see if there is a difference.
Power is down but then fuel consumption should be down too. I'll see how this tank goes in a week or so. So far, its not worse. Fingers crossed.
I'd post pics only is damn ugly in the engine bay!
