Intake Manifold Flow #'s

IQ52, speaking of spacers. In my dyno testing I made 10-15 more HP on the Eddy RPm when I used a 1" HVH super sucker spacer.

Have you ever tried one of these on a VIctor?

Every combination is different and you have to try what you have access to, or be willing to buy and experiment.

I have never tried a 1" spacer on a Victor intake. I gain on a Victor when going to a 2" spacer but I gain a greater % on a single plane M1 than I do on a Victor. I didn't gain enough to spend the money when I used a 2" spacer on the Super Victor for the 426 small block.
