Hi Bill,
Looks like you've made great progress since we last spoke.  I= t shouldn't be long now.  Are you planning on attending Tracy= 's (actually, I should say Laura's) rotary roundup?  Lots to t= alk about.   
 
Concerning your cooling system, I assume the air comes in the bac= kside of the radictor?  What kind of inlet & diffuser did you use?=   I measured my airflow today through the radiator.  It flows 40 = knots at 120 knots IAS.  It may be a little fast.  You may want t= o measure yours, when the time comes.   
 
You mentioned that you were measuring coolant temperature after the ra= diator?  I think you also need to measure it as it leaves the engine.&= nbsp; This will tell you how hot you're running and how close you are t= o redline.  Just the opposite as for the oil. =20
 
If those hose clamps are not constant torque clamps, please consider u= pgrading them before first flight.  They're available from McMaste= r. 
 
Keep up the good work.  Hope to see you at Tracy's.

Notice the bypass hole that you guy= s are talking about needing to plug.  This hole is in the housing whic= h has been removed, so it is not a player.

The little rag you see on the oil l= ine is a high tech way of checking for a leak. (I have one!)<= /p>

 

The red wire is the air temp sensor= for the air after the radiator.  It is on top of the fan.

Hoses are 1 =BC"  The temperat= ure sensor was moved from the left side of the inlet to the top

But is reading temperature as it en= ters the engine after the radiator. (coolest place)

 

My overflow catch can.  I will= be replacing this with a pressurized on as per Lynn's suggestions in a pre= vious post in order to introduce=20

An air cushion above the liquid und= er pressure so it will not be "locked".

 

I am planning to try and put suctio= n on the cowling at the exit with a leaf blower in addition to the prop bla= st and the small fan to see if an increase in=20

Air flowing will help.  I have= n't checked the sides of the radiator yet as I have been alone when running= the engine=85.

All inputs appreciated.  I alr= eady know some things should be changed, so don't hold back with the sugges= tions.

 

Thanks,

Bill B
