engine dyno
testing & tuning

Restoring or building an engine for your project can cost thousands of dollars. Engine dyno testing before installation can save you time, money and endless headaches by making sure that it runs and performs to perfection when you turn the key the first time!

dyno testing your engine

An engine dyno allows you access to all major engine components and support systems, making tuning your engine quick, clean, and efficient. Testing your engine’s oil pressure on the dyno saves you having to access hard to reach components after the engine’s been installed. During a shakedown on the dyno, you’ll be able to detect and correct leaks and find the source of any vibration or noise. Repeated passes on the dyno allow you to evaluate your build’s controllability under a full range of loads. In the end, you’ll leave knowing that your ignition timing, AFR, oil pressure, MSD/carb, lash and cam timing, and all supporting systems are ready to go!

Our custom-built engine dyno

Like our Chassis Dyno, our Engine Dyno was built for superior performance. It’s built on the same platform that GM uses for their Nascar program. At its heart is a Go Power Dual Rotor water absorber that can test up to 2,400 ft. Lbs. of torque at 10,000 rpm. We’ve proven our dyno has reliability by comparing HP for HP and Tq for Tq test results against engines tested in a government lab.

The dyno can accommodate both carburetted and fuel injected engines with multiple high-pressure fuel outputs for 300 HP to 2,000 HP. We can test gas, diesel, nitrous, and bio-fuel engines – everything from a simple 2-stroke up to 10-cylinder gas engines.

We can test headers of any size or style – including Pulling Headers. Unique to the industry, we’ve introduced a mobile water absorber so you can test your engine with complete exhaust systems from header to tailpipe – even with the catalytic converter and muffler fitted!

We built our dyno test cell to be one of the quietest in the industry and installed a large viewing window so you can watch as we run through the engine pulls. Our pricing includes tuning, but we realize some of you may prefer to do your own tuning and we’re pleased to offer a complete range of tools for your use.

test and tune to your goals

It’s important to identify your testing & tuning goals before your appointment. Your goal may be to break-in, test and tune a rebuild, or to compare the performance of different components such as camshafts, carbs, headers, air induction systems, etc. Or, you may just want to see what she can do! Whatever the reason for your visit, our expert technicians will work with you to meet your goals.

Breaking in a new or rebuilt engine

Properly breaking in a new engine when running it during the first minutes or hours is critical to performance and to extend the life of your engine. If done right, your rings will seat perfectly, and your cam lobes will be properly surfaced. We follow a specific procedure for break-in using carefully calibrated engine loads. After break-in, we can proceed directly to tuning for power and performance!

custom tunes

We offer our own dyno built tunes on Aliengate or SCT programmers. We can provide a tune for your specific need, whether for towing, racing, improved mileage or for your daily driver. Easy to order and install (free shipping).

fleet tuning

Fleet vehicles tend to operate within defined geographical limits. When an engine is properly tuned to the road conditions and driving style you'll have fewer repair costs and realize a minimum 10% improvement in fuel efficiency!
