Wild Thing Nearly Ready For The Pond

[osracer]

I don't think I will be at the speed run. It's Mothers Day weekend and our daughter is coming for the weekend. Give me a call and I could meet you somewhere almost any day next week so you could get the stuff before the speed run.

Later. Bill

I made a keeper that holds it in place.. if it comes off you will water down the carb.

Let me see.... here is a pic.

Mike,

Thanks for the picture. I'll have to work on that. I like the ball joints as retainers. The fit on mine is pretty tight with the o-riing, but I like the insurance policy.

And Bill, I will give you a call.

Curtis and Mike,

You guys appear to be cooling the glow plug - have you found that to be an advantage?

About 30 years ago, I remember John Ackerman was doing that. (Or was it Marty Davis???) I can't remember what the verdict was back then.

 

[eekern]

In Marty Davis' old tech notes he said he could run a point or two more compression without detonation when capping and cooling the plug.

Bob,

I don't have any experience with this engine yet, but this is the way it came from the factory. Interesting design.

I don’t like it.. (bleeping turbo plug).. When the plug goes it goes. The diff between a point or two just is not worth the "engineering" to cool the plug.



I will say this however.. This is WITHOUT QUESTION.. the strongest 21 I have ever raced. My nova LS and CMB 21s did not RPM like this motor does. It makes GOBS of power..



I have some of the new OS 21s and want to get them out for testing too. If I felt like I needed to take a 20 hydro to race NO QUESTION I would start with this motor. (I cannot say how I would feel with this motor in a mono..just not sure, I would need do a bunch of testing)

 

[BobBonahoom]

What brand of motor is this you guys are talking about here?

 

[Curtis Beaumont]

Bob,

It's the OS Vz-M.

It looks like a great engine, but it calls for a turbo plug and the cooling plug that removes to access the plug.

Mike, I would be happy to pull out the VZ-M and put one of those new OS engines in to test. You just let me know.
