Comparison between 13B REW, 13B- RE Cosmo, and 20B UIM

[charlies7]

I have a set of RE manifolds waiting to be tested Dan..This summer I will dyno using both and let everyone know. Too bad I have to run two different fuel systems..At least the secondary rail

Who knows though maybe Phil will beat me to the task. However I am expecting more top-end power and a better power curve..turbo undecided

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
