21VAC P/S IN MAC21 PERFORMANCE (NOT VALVOLA)

[NOVALTD]

To all MAC21 owners: Has anyone installed a VAC 21 P/S in a MAC21 case with the VAC21 head button? The VAC21 P/L is not a green head VALVOLA P/S. The VAC 21 P/S is ported different with a much wider boost port and a much narrower transfer ports. The exhaust port is the same. All ports timing is the same. The head button has a chamber 400 hundred thousands wide vs 350 with the MAC. How did the MAC perform. Was the VAC 21 / MAC better the same or worse over a standard MAC21 .Any mods? Your comments

are appreciated. Dan NAMBA 221
