People dropping FI setups like hot potatoes

If done correctly, the single plane intake will out power a dual plane intake every single time.

Even a cursory study of air flow would teach anyone that putting a corner in a moving column of air is bad. Now add fuel to that column of air, and it's 10 times worse.

You have to build around the intake. A dual plane intake is worthless. It doesn't do anything better.

Of course a single plane will get more total horsepower, but most of the time at a loss to low end torque. Please reread my statement, I said in street applications. I know you love the high RPM builds even for you consider street builds, but that is not everyones cup of tea. A dual plane does have its place, mostly low to moderate RPM engines that see little track time.
