So far I did test flights at different altitudes and power settings . It world like this: I noted EGTs from .5 gal fuel flow before the first cylinder peaks in .2gal steps down untilgbar all EGTs peaked. The data I sent to Don at airflow performance and he suggested to try first a .025 In # 5, a .0245 in #6 and maybe cylinder #2, and a .0235 in #1. I will update the data once I have installed and tested the nozzles.

When positioning the bracket it will come right next to the air inlet flange, just keep that in mind when positioning it. Also, be careful not to put the air inlet too close to the front of the ramp in case you end up wanting to trim it later on for clearance. with the cowl. -------- Bill WA0SYV Aviation Partners, LLC Read this topic online here: http://forums.matronics.com/viewtopic.php?p=418784#418784 ________________________________ Message 4 _____________________________________ Time: 08:38:19 AM PST US Subject: Re: RV10-List: Re: Fuel consumption test results From: PReid I can use some education here. If Lycoming is putting in .0280 and some are t aking the restrictor down to .025, what does that do to WOT on takeoff? Is t he 22-23 gph still being seen on takeoffs to cool the CHT? Why wouldn't lycoming just put .025 restrictors in to start with? Pascal > On Feb 16, 2014, at 12:25 AM, "Mike Whisky" wrote: > > > Sure will do.

IIRC that is somewhere around 15 psi in stock form. On Sun, Feb 16, 2014 at 9:37 AM, PReid wrote: > I can use some education here.

We also checked for adequate takeoff fuel flow; I don=99t remember the exact number but I think it was appox. 23-25 gph. I usually see at least 25 gph.
