Hey guys, 

  

 Thought I would post a question.

  

 My engine temps are quite good, but I don't develop the thrust/speed that  my compadres possess during formation takeoff and also at formation  cruise.

  

 At cruise in formation with EGT's matched I am turning about 4% more  indicated RPM than my fellow L-29 buddies. i.e. I'm at 94% and they are at 90%  with matched EGT and matched speed.

  

 I have talked to a few different guys and also a warbird shop on the field  here at Reno, Stead and I have got a range of input on what to do such as:

  

 1. Adjust the fuel controller to deliver more fuel since temps are  good .

 2. Wash the turbine blades

 3. Put a smaller Nozzle on

 4. Replace the engine with a factory zero time overhauled engine.

  

 Anyone else encounter this situation or have any suggestions.

  

 Thanks,

  

 Scott

 The engine that is!

Along that line, do any of you guys know what the equivalent horsepower the L-29 engine is putting out at cruise, say?  I know it's not a direct comparison, yet crossover formulae do exist -- I just don't remember them  

 

 Thanks,

 David M.

Does the engine gives 100% at full throttle ?What is the EGT at full throttle ?

What is the  fuel pressure at 100%

Does the runway take off lenth seems normal ?

May-be you have to adjust the fuel controller to deliver less fuel

There are variations in fuel controllers for different year airplanes,

then there are the weight disparities, some people removed a lot more

than others, then there is CG, if you are flying with more forward CG

then the others then you will affext your cruise speed.  Also there

are discrepancies between different gauges.



I pulled and cleaned my fuel nozzles last year, they were heavily

carboned up, and it did make a difference in power and fuel

consumption.
