If they arent then the manifold will maximize air velocoity and make gains. Obviously its only na but 15-20 hp through the power band isnt unrealistic. People are sitting at like 336. 350zs made 312 ish with a manifold of the same design. The vq will benefit from this and I know some of you guys are running a little higher redline so you will see power up top.

I already talked to my shop and all of these gains are with supporting mods, long tube headers being a big factor
