Prove it with the SF-4000HD, SuperFlow’s first 4000HP engine dynamometer.

Prove it with the SF-4000HD, SuperFlow’s first 4000HP engine dynamometer. We’ve listened to our customers who have asked repeatedly over the years for a test stand that could compete with the rising horsepower of today’s engines. Through advanced in-house engineering, design, fabrication, and production, SuperFlow has delivered the industry’s first complete testing solutions for high horsepower engines.

The SF-4000HD dynamometer system has been developed for customers that require an affordable solution for testing high speed diesel, gasoline, and alternative fuel engines. With a new stronger dyno shaft (w/splined coupler), a rigid, robust frame design, and a water brake based on the legendary Stuska design, SF-4000HD provides reliable testing for 4000HP engines at speeds up to 12,000 RPM. The larger pump and water circuits handle the increased water needed to load even the largest of power engines. Bigger bearings, new high RPM seals, easy access servicing, and plenty of other features helps this dyno set the standard for excellence in high horsepower testing.

Complete with WinDyn Data Acquisition & Control Software and utilizing a Stuska XS-211-HD water brake, the SF-4000HD makes testing easier than ever before. With one system, direct from one supplier, modernize your testing capabilities and completely transform your shop. Where the other dynos begin to fail, the SF-4000HD is just getting started.
