Question, and new results!

[aceofd1amonds]

First the results:
PPK
Jetworx
Jims Plate
1200 Grate
tighten the loose throttle cable upgrade
1/2 tank of fuel

...

70.1mph supermanned!

Which is better than my last 69.5! Just running better today i guess!


Now for my question. After i got the jetworx and pump plug kit, i notice a high pitched whine when i take off slowly. Just for a second. I dont know if maybe the impeller is ringing off the wear ring or something like that? i dont know if this is normal or not. Please advise.

I dont think so. Still the stock prop, and the liner had a little wear.

I dont know on that one Kade. Call you later.

still no ideas on that little whining noise? I should note that it goes away after i ride through its frequency (rpm level)....

I will be in Beaumont this weekend if you wanna come ride Sunday.
We could listen to it then ?

wish i could, but ive got to work. Im sure it'll be fine. If something flys off, or catches fire, we'll know we've got a problem.

That type of noise is usually the pump bearings going out. Remove the pump and spin it by hand and see how it feels.

what happens when they are ruined?

what happens when they are ruined?

you have the whine...sounds like an in tank fuel pump in a car going out.. and you have what feels like the prop slipping on the driveshaft when you first launch at the ramp.. it'll slip and slingshot you a couple times then it's fine the rest of the ride.. except it's loading the engine..

i had no rpm loss..just the above and my engine ran slightly hotter. I pulled it apart and water poured out of my pump brgs. Fixed it properly , corrected the cause, and whine went away. Chk'd my pump last week (after last yrs rebuild) and it's perfect.

Its possible, but I had the pump out a couple of times and they felt fine.

Kade call me when you get a chance

And speaking of pump noises... call me Fercho
