Ralph,

 

I am having great luck = with my fuel injectors from Airflow Performance (http://www.airflowperformance.com/).&nbs= p;

These guys have been very helpful to me and are = much, much less expensive than GAMI.

 

LNC2 flying = LOP

Averaging 7.8 GPH, above 10K feet altitude at 180 = kts TAS.

Hi = All

 

Recently I went to the LML to see if anyone had a = fuel injector part number 652312-612E, with no luck.

 

I have = and IO-550 G/N Continental engine. Recently I had a fuel injector crack = and eventually break while torquing. The part number for the injector is = 652312-612E which is a tuned injector for the number 6 cylinder which = was used in the 2005-2007 time frame. I have attempted to find a = replacement with no luck.

 

An = A&P was given some new injectors for IO-550N engines in Cirrus = planes which were replaced with GAMI injectors. These Cirrus injectors = (not GAMI) were also tuned (not my part number) and had a cylinder = number imprinted on them. I installed the number 6 cylinder injector in = my engine. Attached are the results of a GAMI LOP test which appears = satisfactory.

 

On the = first test we had the low boost on and the second test the low boost was = off:

1 - 9500 ft, 2480 RPM  = 11.7 gph to 11.4

2 - 8500 ft, 2480 = rpm  12.7 gph to 12.2

 

My = concern is when I am taxing the number 6 cylinder temperatures are about = half the temperature for all the other cylinders, e.g., CHT 125 versus = 240, EGH 425 versus 880.

Thanks in advance for your = thoughts,
