to predicting their ET from weather or weight
changes. It can be used for engine calculations
including dynamic compression or valvetrain
math, fuel system and injector flow, speed, gear-
ing and tire size calculations, 4-link suspension
setup, header size, forced induction with turbo
or superchargers, etc. Gearhead Pro can also
estimate timeslips based on HP and weight, and
calculate air density and power correction fac-
tors along with drilling and tapping information,
unit conversions, etc. Search “Gearhead Pro” in
the App Store or Play Store.

Leak Down/Compression Tester is the ultimate
tool for getting an ultra-accurate read on en-
gine cylinder and fuel injector/barrel valve leak
percentages. Input air pressure and hose length
will not affect readings, as long as the incom-
ing air pressure is above 90 PSI, simplifying a
sometimes-finicky procedure. The tester can
read up to 400 PSI, ensuring it meets the FAA
(Federal Aviation Administration) Standards
for leak down testing of engines with cylinder
bores under five inches. This Digital Leak Down/
Compression Tester will allow any racer to stay
on top of the maintenance needed to keep any
race engine turning out maximum performance.
