That is the pressure I use for my Renesis. There is a calculator on the lower part of this page that will tell you what injector flow you will get with the fuel pressure changes. http://www.witchhunter.com/injectorcalc1.php Bill B -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Charlie England Sent: Saturday, January 19, 2013 10:43 AM To: Rotary motors in aircraft Subject: [FlyRotary] Renesis fuel pressure question While perusing an old document describing the then-new Renesis, I noticed that the fuel pressure was spec'd at 392kPa, which if Google is to be believed, amounts to 52psi. How many of you are running pressure that high? If you're not ( I seem to remember 30-35 for a lot of installations), how much does that affect injector capacity and fuel atomization (efficiency)?
