This return on investment workbook is designed to give you more than just numbers; it is designed to give you the information you need to make a SuperFlow chassis dynamometer a profitable tool for your business. Consider the ideas in this book a starting place to build a successful business plan around your new SuperFlow chassis dynamometer.

Many shop owners biggest fear in purchasing a dyno is the impact it may have on other parts of their business. If implemented correctly, a chassis dyno will enhance and stimulate other areas of the business. While the primary focus of this workbook is about generating revenue with your SuperFlow chassis dyno it is important to note that a SuperFlow dyno is a tool that can separate your company from others and in doing so generate income in a variety of ways. These include saving money, increasing shop credibility, eliminating come-backs, increasing part sales, attracting new customers, retaining existing customers and increasing individual purchase amounts with the ability to immediately quantify the improvements being made.

We’ve taken our 40+ plus years of experience building accurate and repeatable dynamometers and combined it with great ideas shared with us by customers to generate a guide that will help you find opportunity to generate income with a SuperFlow chassis dyno. If you think an idea presented in this downloadable investment workbook will work for your shop, simply add that amount in the space provided. At the end of the workbook you’ll quickly see that the monthly payment is covered in only a few dyno sessions which leaves the rest of the month available to add money to your bottom line. Keep in mind a well utilized SuperFlow chassis dyno will pay for itself in 24 months or less.

Useful Flowbench Tools

Many of the applications of flowbenches and the data they provide are often set apart from normal data because of the mystique associated with flowbenches and flow testing. Engine component airflow data is easy to compare if you know how. Here are tools we recommend using to make the job of testing airflow easier and much more fun than makeshift approaches.

Magic Wand

It provides an indication of activity and direction of flow inside a port or device under test. The magic wand is made from a 1/16” diameter welding rod that is 12” long. The welding rod has a small round ball on the end – from placing the road in a molten pool of metal – and a piece of dacron or nylon type kite string glued to itself to form a little flag about 3/8” long. This is a good flow visualization indicator.

Pilot Tube

It provides a way to probe the port to supply local velocity numbers. It can be used with SuperFlow’s FlowCom, pressure manometer, or special port software to plot areas of activity in the airstream in a port. It’s difficult to use in very small ports. It requires one type for exhaust use and a different one for intake use.

Flow Ball

It provides a method to probe a port and verify if flow is attached or separated at some point in the port. Flow balls are made by tack welding various diameters of ball bearings to a 1/16” diameter welding rod that 12” long. Flow balls typically start with 1/8” diameter and go to ½” diameter in 1/16” increments. These tools are an easy way to find problem areas in the port without great difficulty. It’s very effective in evaluating the short-turn radius in a port of where a wall has a directional change.

Port Molding Rubber

It provides an easy way to look at a port. The mold is made of silicone-based material (a two-part process) that is poured into the port with value in place. After it sets, it can be removed in one piece. The mold can be sliced and the cross-sectional profile drawn on graph paper to help measure the area at different locations in the port.

Graph Paper

This creates an easy way to measure the cross-sectional area in a port. The paper cutouts are trimmed to fit different places in the port, and the squares can be counted, providing an accurate way of measuring the area.

Poster Board

This creates an easy way to make patterns to help the developer reproduce the same port shape and size. The poster board can then be used to trace patterns in aluminum or plastic that provides benchmarks for the developer to use in duplicating an established shape in other ports and cylinder heads of the same type.

Radius Inlet Guide

It provides a smooth approach to the port or device being tested and is intended to decrease the “edge effect” at the port flange. The radius used should be as large as possible and at least ½” radius. The thickness of the inlet guide should be at least 50% of the height of the port. The size outside the port cross section should also be least 50% of the height of the port so all directions have a smooth approach. It is not uncommon for the inlet guide to improve the flow from 6% to 10% over no guide in use.

Exhaust Pipe

All testing of the exhaust side of the cylinder head should use a short section of exhaust pipe that is at least the diameter of the port. The appropriate length is about 10” to 12” long.

Bore Simulation Adapter

All flow testing of cylinder heads should use an adapter that simulates the bore size within 1/16” of the diameter used on the engine. The length of the simulated bore should be at least equal to the diameter or more.

Wet Flow Adapters

It provides another reference of flow visualization that is valuable in evaluating what is happening in the combustion chamber and helps to sort out problems in that area. It’s best when at an air/liquid ratio that represents the normal air/fuel ratio an engine uses. This process has helped solve problems that would otherwise go unnoticed.

Calculator

Ever present at any testing is a flow tester on the phone comparing numbers with another tester. It provides an instant indication of hype vs. truth because known numbers are compared to claims.

These are basic tools you need on hand for airflow testing, which will provide incredibly insightful and helpful information.
