|
|
For you users of Whirlwind props, what governor are you using?
WW recommends the Jihostroj P920 which sells for approx $1,250. Van
sells the MT P860-4 governor (also made by Jihostroj) for $1050.
Will Van's MT governor work on a WW 150-151 prop which requires a
pressure of 450-475 PSI? Do MT props require the same high pressure to
operate?
Any fit problems with either governor?
Thanks,
Charlie Brame

Due to a smaller piston in the hub the WW 150-151 require the governor
pressure to be in the 425 psi range rather than the 325-350 range. WW buys
the Jihostroj governors specially modified for the higher pressure,
therefore the MT version won't work for the WW 150-151.

Are you saying that the modified Jihostroj P920 governor is the only
governor that operates the Whirlwind 150-151 propeller?
BTW, Jihostroj made the P-4xx series governor for MT Propeller.
The P-8xx series governor number became necessary to differentiate a newly
certified manufacturer for an identical performing governor.

Yes, as far as I know. Check with WW to be sure...

Thanks Randy,
Finally got hold of the WW folks who said the same thing as you did.
Ordered a new Jihostroj from them.
Interestingly, the folks at Van's insisted their MT governor should
work.
Thanks for the reply.
