Aeroslave pipe set-up.

[Wayne Galligan]

Coiln,

If the engine is running too rich in the mid range lengthen the pipe.  This pipe needs a little longer setup then Lance originally posted. When I went to the AeroSLave pipe I installed it the same length as my previous pipe and it was slobbery rich in the mid range.  I had to lengthen it about 1 1/2 inches.  If it comes on the pipe real hard then it is way too short.  This pipe when at the right length will be real smooth in transition and not come on the pipe hard but have a smooth constant power on top end.
When it is at the right length then richen the low needle as much as it will stand with out loading up and you downlines will be much, much better.
I will measure mine tonight and give you an exact length.   I run a 17x12 APC and a 15.75x10 3blade by Lockhart and they both are real smooth on the power.

  Help needed...tuned pipe problems!!

  I've bought the AeroSlave CF pipe for my OS140RX turning an APC 15x11 4-blade. Aeroslave gave a starting length of 29.5 inches from the engine exhaust port to the end of the pipe. However, the engine runs extremely poorly at this length. In order to transition past the midrange the high end needle has to be very lean resulting in a lean high end. The power comes in with a bang and the engine accelerates in down lines. I think this is too short a pipe length although the header is full length.

  Does anyone have any experience running these pipes on OS engines? What's the best starting point?

  Colin.
