Interesting, I’ve never really thought about it before, but your two responses got me thinking. I’ve always “heard” the RE intake manifold increased low end torque, but that does go against conventional wisdom when compared to the REW intake. Generally increasing the intake runner length increases low end torque. Unfortunately they are not a direct comparison as the RE intake does have larger primary runners and the parabolic chamber. I guess there is no way of knowing for sure without testing.
I nominate Phil as the guinea pig to test it out
