It's worth reading the summary section on page
29. It's only 2 pages
Highlights:
- swift fuel weighs 21% more but only increases
range by 8%
- if you are weight limited for fuel you will only
get 89% as much range.
- if you are gallon limited for fuel you will get
8% more range
- egt's increase by 50 dF. On my installation
that would mean having to back off the mixture an additional 50dF to keep the
TIT's in range
- something about aromatics I didn't
understand
Overall:
It's better than not flying but not as far or as
fast as 100LL.

Subject: [LML] FAA Swft 702 Fuel test
report
I found a link to a pdf of the
Swift fuel test report from FAA testing done last year. Looks like there
is a heat issue ( around 50F greater than 100LL) and peak HP is about 1.3%
less than 100LL.
I know very little about the
chemistry behind fuels and engine design, but if more heat is generated, how
come that can’t be harnessed and turned into
power?
