Super Jet 148 Torrent Mag - Impeller Pitch??

[Parsonsjb88]

Hoping someone, or multiple people can offer me some advice on the pitch I should get for my 148 torrent setback, standard torrent cone. Stock thrust nozzle from the Ez-pull Thrust kit.

I have a 760cc ported 61x cylinder, ported 62t cases, bpipe, dual 44 carb, 38cc (185psi) ada domes and head, msd, lightweight flywheel & couplers, and TNT Waterbox.

Suggestions?

We will all need a few more details to help.

Measure the thrust trim kit, reduction and steering sizes needed. Some were different sizes
Hull
Weight complete or bare hull if known

Thanks for the reply! Its a RN superjet that I highly modified. Bare hull was 100lb. I'll measure the nozzles tonight

I have a Torrent 148 non-setback in my FR-2 EVO. CPT 771 (200psi) Dual 44 carbs, B-pipe FX1 chamber, Light flywheel, MSD enhancer, light couplers, stock waterbox. I went with a 7/12 and I'm very happy with it.

Thanks! I forgot to check last night, hoping to get to it tonight to measure the diameters and maybe snake a borescope in to read the prop pitch (assuming it wasnt tampered with).
