View attachment 7111 I've been curious about the Elio intake manifold - most visually exciting thing on the engine. Why are the intake runner tubes so long? Does that not potentially allow condensation to form in the intake...or preheating intake air from engine heat? Both are not desirable. Nice to see them so large relative to the engine size...will make it better for a turbo. Why are they circular like that...does it create vortexes that are somehow advantageous?
Long intake runners, when used in conjunction with proper valve timing and duration, increase low to mid-range torque and make for good driving dynamics in the real world (part throttle operations). Plus, it helps with keeping good brake specific fuel consumption.
