I think it is important to keep it as light as possible so spinning in aluminum would be ideal.
The metering plate is balanced in the CIS and adding weight to one end of the lever arm will create an imbalance against the piston/plunger end. This will be compensated slightly by increased control pressure but the overall change should be kept minimal.
The big benefit is increased control of the crossectional area that the air must pass thru between the metering plate and inside cone surface of the housing. The cone should also increase total MP travel so that stall and extra plunger movement happens at max air flow rates at high load and rpm.
I would be interested in buying one as long as they are tested by someone on a dyno for results in a controlled back to back test. Someone must measure A/F ratios and hp numbers during the run with and withtout the cone installed.
If you could post verified gains I would bet lots of guys would sign up to buy this thing. I don't buy things like the aftermarket plastic air filter housing because the supplier selling it tells me it makes 15 hp without proving it works with data.
Rarlyl8 does alot of testing and I value his comments, maybe he would be interested in developing this thing? I don't want to speak for him though.
