You may be able to open the stinger and still keep the heat in the pipe. This may be the pay off for that pipe. That may let it spool up more at the end of the straits.
From the video it dose not seam to spool up coming out of the corner. Just going around in circles as a call it.


Dave will do I can go all the way to .450 I'll do the .390 this weekend. Thanks Charles

Did it gain any RPM's at the end of the straits with the bigger stinger?

What about the temp of the pipe to the touch after a hard run? Can you touch it and not get burnt?

So the pipe is much cooler to the touch than a aluminum one?

Ya I couldn't believe it and what heat it gets off the header it disappates quickly.

I wonder what it doses to the air temp in the pipe? My thinking is that it gets hotter from not heat sinking to the air.

Would love to here from those that have a better understanding about this.

Any thoughts AB????

Dave you got a 45 I wouldn't mind letting you try it out. My conditions hear are so different from yours with heat and humidity.

Hi Charles- do you plan on making pipes available?... I have the geometry, just not the manufacturing capability. 

 

Thanks,

Tim

Charles I'm taking a break from RC boats right now. Building a old Vector the boat in my avatar and gust about ready to rock and roll with it.

It may work better in the cold and make more of a difference. Keep testing you will get the info you need.

Timbo what are you doing over here??????????????
