Impeller choice x4 800 limited engine

[Ashr88]

I'm running 15-25 solas concord on my bike at the moment and it pulls hard like a train, but I'm after a little more top end now, was thinking to run a set of 85-88 r&d reduction nozzles with the 15-25 concord impeller to gain abit on top.
The ski dynoed at 127bhp so it got the power to pull it. Thoughts welcome??

What is yours mod? Do you had tge papersheet dyno? Put here!!
Yes good idea! Do you use ECWI? I do not recommand msd pn4259....because the start point injection water is 3000rpm...i recommand pn42592 or microtouch for coffman 787 or951
The star point water injection is 800rpm for 787 and 1100 for 951cc
You will get great kick ass for pulls up water....day and night
