will riva pro reduction nossle help me with x charger?
i have the stock impeller for now and just installed the x charger with 42 injectors. im at rev limit. will a pro nozzle reduction kit with 81mm ring bring my rpms down enough for now untill i buy my 15/20r?
the problem is i plan on making alot more mods anyways so the reduction nozzle will be a nice addition to the mod list but i can only afford to buy the reduction kit or the 15/20 right now which would you guys consider .... im afraid with just the x charger im not going to spin the 15/20r enough untill i get the ext cooler and the 4in intake

Are you burning the prop off the bottom? If not or not too bad, just pitch the stock impeller a touch-- try .040" to the trailing edge-- worked great on my my ski until I added the external intercooler which took a total of .091" to the trailing edge to get it off the rev limiter (x charger, external intercooler, 160 thermo, 42's, home made air setup). When I went to the Solas, I had a hell of a time getting my rpm up-- 1 1/2 days of pitching and repitching AND repitching to get it just right...

if i were you i would just have your factory nozzle set up to accept the different ring sizes. and pitch your prop it should not cost you more then 100$ to have your nozzle set up for the rings.
