Odonnell #9 & #89 Plug Test

[Joe Warren]

Today I went back to the lake to do a detailed test of the Odonnell Plugs. Most all Normally run MC9`s for High Nitro (cold plug). After Zooming around the lake for a few tanks & got to a fast Rich needle. I came in & took the McCoy 9 out & installed the Odonnell #9. Back on the water to test for speed & back again to compare. Each time I changed props 6.2 6.5 6.7 6.9 60% Nitro on 80/20 oil I went back to the Mccoy 1st then back to the Odonnell #9 & #89 Final Twin test on Roadrunner Twin with RS91`s fully modified, Andy Brown 1667 6.9 props. Also tested a Seaducer 47 Nitro Mono Modified RS101 with X470 7.5 T.E. same test each time I changed props examined the plug condition & changed the Brand. Neither of these test was a little buzzzzz around the pond. Both were with MAX Effort props & Short pipes for High prop speed & High Engine Load. 6 gallons blew thru today testing...... I was trying to find the limits of the OD #9 & #89..... From what I can see..... we will all be running Odonnell #9 or #89`s very very soon...... EXCELLENT PRODUCT! If you SERIOUS about Performance with Max Effort Props & Pipes This is the Glow plug you have been looking for...... If you can find the odonnell #9`s @ LHS you Better SNAP Them Up!!!! #89 are hard to find at most LHS.....

Joe is that a converted Gad boat? I always thought that would be a good combo...

Yes it is a 47 Seaducer Gas Hull, I ask Seaducer to build it with 44 Stringers & installed 44 Hardware....

Joe

It's about time you caught on.

No doubt that the ODonnell 9's, 88's & 89's are the best on the market.

BUCKSHOT I have Ran & Raced them. But I wanted to do a comparision test on the same day with the same conditions with the same load. AS you know the RS101 with the Big Cup props will Test Any Plug..... the #89 are hard to obtain here, other than the few Tower sold .....

Looks like the #9 & #89`s have dried up @ Tower??? If you SERIOUS about Performance with Max Effort Props & Pipes This is the Glow plug you have been looking for......

well to bad your now figuring that out man because odonnel isnt dried up at tower they discontinued them and i bought them out but yea 89 and a 99 odo non turbo is a sick plug and its beefier than a mc plug so they can take abuse hope you bought some stock from those guys

 

[ALLAN YUEN]

OD 9 & the Sport Blue plug is NOT the Same plug..... they are intended for 2 diff uses & they have different wires in the socket......

[Brian Schymik]

so tell us more about the blue plugs Joe, they are available

 

[Grimracer]

Joe,

Take notes of your fuel usage as well. We found quite a large differance between the plugs you are testing.

Brain,

To the best of my knowledge the Blue plug has the some hole dia and wire as the OD-9 but lacks the wafer seal in under the seal washer. (the blue uses aluminum and the OD-9 brass)

The OD-9 is a real gem! My favorite for sure.

Grim

 

[Rigged]

been running #99's in my on-road .21 engines... love those plugs. McCoy who?

 

[JeremyEdge]

I used the blue no problems....

Both use the same seal.

 

[Rigged]

Jack...what is the difference in the Blue Sport plug and #9?

I wish the places around here that are advertised as O'donnell dealers would actually order O'donnell stuff. Save me on shipping costs. :angry:

 

[julianconde]
