What You Can Do with a Hewitt Inertia Dyno

What can you do with a Hewitt Inertia Dyno?

The following is based on these assumptions; you bought “Pro” software with S.A.E. weather corrections and have at least one analog temperature channel (head, ex, oil/crankcase, coolant, carburetor inlet temp, etc) sensor.

• You can graph S.A.E. corrected torque (tq) and horsepower (hp) in relation to engine rpm.
• You can do up to six graph dyno pull overlays/comparisons.
• You can click on any part of tq or hp lines and see data in 1/100ths of an increment at any rpm. Including graph overlays.
• You can compare any dyno pull to any previous dyno pull in your computer.
• You can zoom in on any graph down to 30 rpm engine increments.
• You can print anything you can see on graph or reports.
• You can see S.A.E.  Correction number instantly along with date and time along with peak tq & hp in relation to what rpm these occurred.
• You can see tq & hp numbers in relation to engine rpm in report (Excel) form instantly.
• You can type in any comments before or after dyno pull and save.
• You can compare any sensor in relation to engine rpm.
• You can see average of any data/sensor in rpm increments (50, 75,100).
• You can show or print any data and difference of data in report form (excel) up to six dyno pulls at a time.
• You can see total time in seconds of any rpm range in .001 and compare to other dyno pull side by side. See what change made engine accelerate faster over certain rpm range?
• Dyno clutches/torque converters etc. see engagement rpm, Slippage ratio (how much does clutch clip?), see were total lock-up of clutch occurs (at what rpm) in relation to engine rpm or in Time (seconds).
• See real time weather information.
• Print test comments on graphs or reports for customer or yourself.
