The home of GAMIjectors® fuel injectors!

For many years, pilots and mechanics with a good understanding of the operation of internal combustion engines have known that the fuel/air distribution in our aircraft piston engines has been less than optimal. With the invention of multi-cylinder engine monitors, many pilots started watching an unsettling graphic display of just how far from "optimal" or "uniform" the cylinders were running in their engines.

GAMI has developed and certified specifications for a set of precision fuel injectors for almost all engines in the current Continental and Lycoming fleet of fuel injected engines. We have STCs and PMAs on over 300 different engine models!

GAMI Should Be Allowed to Sink or Swim On Its Own

Early in the week at AirVenture, GAMA's Pete Bunce declared that the market would determine which of multiple unleaded avgas products would ultimately prevail. What he failed to mention is that GAMA, the other alphabets and the EAGLE industry consortium have been hell bent on keeping their thumb on the invisible hand's scale. And they're not reticent to use federal law to do it.

The Lean of Peak Saga

In this article from SA Flyer Guy Leitch and Paul Ferraris cover the basics of how GAMIjector® balanced fuel injectors enable you to properly operate your engine leak of peak EGT and provide insights into the myriad benefits of doing so.

... to summarise, we were going two knots faster on 6.6 GPH less fuel. The hottest CHT was 22°F lower than when operating RoP...

FAA Approved Airplane Flight Manual Supplement

GAMIjector® and turboGAMIjector® fuel injectors, when properly tuned using the GAMI Lean Test procedures and with the aid of an every-cylinder EGT/CHT engine monitor, will allow the engine to operate in a wider range of fuel/air mixture settings than originally available when the Aircraft Flight Manual or Pilot Operating Handbook was first published.

GAMIjector® fuel injectors save thousands of dollars!

We recently had an email from one of our customers who uses a 1969 Cessna 206, with a Continental IO-520-F to perform repairs and haul parts to remote villages in Alaska for a plumbing and heating company. He has calculated that GAMIjector® fuel injectors saved his business a total of $6,786.00 from March to August of 2012 alone!

Should have installed these a long time ago.

More great feedback. Some of our favorites are from people experiencing the magic of our fuel injectors for the first time:
"I sent my JPI files to John-Paul and my current spread was .9gph, 3 days later my new injectors show up, we installed that day and went up for a quick flight, noticably smoother and a new spread of .5gph. Talked to John-Paul again and he is sending out 3 more injectors to fine tune her to what we hope will get us to a .3gph spread or better." Read more...

How lean of peak can save on more than your fuel bill. There are precious few circumstances in which pilots can cut their fuel burn, reduce costs, and extend the lives of their piston engines at the same time but lean-of-peak engine operations is just such a rarity.
