2007 gpr nozzle diameter?
I put a solas 14x20 dynafly prop on.I read on the R&D site that without a 87mm nozzle it will reduce performance.I cant remember where but I think I read that the later model gprs had 87 mm nozzle or is it 85.I just did a speed run yesterday and at 90degrees and light chop did 67 on gps.77 on dream-o-meter.I know i need a real tach for true rpms.R&D says without 87 nozzle it will be 6850.My recent mods
pump seal kit
ejk at pre programmed settings

I'd say you need a grate with the PPK, Solas and Plate.

concord uses 87mm, dynafly uses 85mm
03+ GPRs came with 85mm
