intake manifold design for a 200X
So I'm upgrading to a 29mm mikuni carb that came off an XR200 and although its an aftermarket carb it worked quite well. On the XR it used a rubber intake boot that was bolted directly to the head and the carb was clamped into the boot at an upward angle. That being said here is where my idea come in. I'm big into early 90s Chevy EFI stuff and the Tune Port Injection 305 and 350's used extremely long intake runners, lets say 10 inches or so of runner before entering the cylinder head and they make tremendous torque throughout the entire rpm range because of the intake velocity developed by the long runners. The stock intake manifold on the 200x is about 2 inches or so in length and I don't know how much it contributes to the relatively good torque the 200X makes. I am going to need to make an intake manifold for this carb to fit and I'm debating whether or not a longer intake runner would help promote better velocity and torque overall or not. Has anyone ever experimented with anything like this on an ATC engine?
