Diffrerence between 82 and 79mm Pulley

[Schnell GT500]

So i'm trying to see if it's even worth going from my 82mm to a 79mm pulley for my Gen 1 VMP TVS. Anyone have power numbers between them?

I’d say no as it’s only .1 inch difference so you’ll gain roughly a pound of boost so that’s worth 12-18 hp depending on any supporting mods.

I went from a 82mm to a 80mm Griptec pulley with a new RPM Gates belt and picked up 18 rwhp. Before dynoed at 691 rwhp after 709 rwhp. I only did it because i was soo close to hitting 700 rwhp before and i knew i would hit the number with a simple pulley change.
