tested my new motor today

[w-nut]

ive just finshed putting a new motor into my x2 on thursday. ported 750 small pin cases, v force2 reeds, duel 40mm kehins, weisco forged pistons, new sxr 800 cylinder , sxr head(175psi) and a 650 fpp mariner water box. man this engine rips you really have to hang on to it now you can feeling it streching your arms. some friends that race had there radar gun at the lake this morn so i thought id see how fast it is up top and mangaed to get a 52.8 mph .
just some very minor jetting tweaks down low and im all set for summer :Banane01::Banane01:

Do you have any rpms numbers?
What pump & prop you running?
You boats sounds like it's set up right.
Enjoy it.

I'd like to hear what rpms your pulling. If I were to guess between7250-7350
The mag pumps put a lot of load on the motor but it sounds like you have it proped right. What exit nozzle size you using?
I have a wet piped sxr with 9/17 with tbm cone & 80mm nozzle pulling 7200
with the stock prop, wet wolf stubby cone, & 78mm nozzle was pulling 7280.

Scorn what MPH can you get running each of those setups?

Im running something similar and might change to a wet pipe.

Does the tail cone make a noticable difference in the bottom end?
