Default ECI cold air intake

8 months ago I changed over to the ECI cold air intake system. My previous system was a vertical induction warm sump with an elbow facing forward, and Bendix fuel injection. I mounted the Bendix to the ECI sump and plenum. The ECI parts are made of a Magnesium alloy. I also had to change my 4 into 1 exhaust to a Vetterman 4 pipe exhaust for clearance. Too bad I had to change two things, because there is no way to know for sure the effect of the cold air intake alone. It is widely held that the 4 into 1 makes more power, but I am not convinced.

Anyway, I gained 3 knots with the new setup. Working backwards with the cube law, that suggests I gained 9 horsepower.

With dual Lightspeeds Plasma IIIs, the plenum has not broken and fallen off yet.

Looks like I'll be eating a large slice of humble pie - thanks to Mahlon and John for providing the information. Anyone want to buy a vertical draft sump and a Sky Dynamics Injector Relocator kit?
