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!

Brought my Merkur to get tuned after being parked for 4 years, during that time it got a built motor, transmission and turbo upgrade, Marc, Wally and Chris all did a spectacular job, even when scratching there heads for a couple issues, they kept on having a positive attitude and even tried to teach me a few things and show how the process is done, these guys are definitly beyond the definition of professional and will take care of your car and you, I completely recommend bringing your car, bike, anything with a motor and these guys will figure it out and will help make safe reliable power. Even gave the Merkur a plug in his Facebook Livestream!! If you want to see what these guys do check them out of facebook or give them a call, these guys have your back.

The best dyno shop in Ottawa ! They treat you like family. Very professional and knowledgeable. I had my 5th Gen Camaro SS tuned by Marc and Wally and left smiling from ear to ear. The car runs super great and I have absolutely no complaints. Marc explained everything clearly and Wally did his magic, they got the beast out of it ! 75HP increase and over 100TQ at the wheels. It feels and drives like a new car on steroids. I would highly recommend this place for your tuning needs. Thanks guys ?

Marc and Wally are great at what they do! It's a real pleasure to work with them. There's no pretense or posturing here just good honest HOT ROD experience. Marc answers the emails you send..good communication no flakiness like so called other tuners or experts...They were able to pull about 60 extra HP out of my 440 Charger. As well they had me back for a small adjustment I wanted done and Wally diagnosed the problem in about 3 minutes and tweaked the program on my MSD EFI and POW!!! Throttle response I was hoping for...wonderful....

Came in to get my axle and tire size recalibrated. Easy fix, but why stop there?.. you are at a Dyno shop! Woke my truck up from a 20 year nap. Less fuel, more power, and you wouldnt know my short box chev is a V6. The guys are great to deal with, very knowledgable, and talk honestly. The guy that left before me said "You will love this". 60s guy in a 60s muscle car with a smile bigger than a kid with candy. He wasn't wrong.

Hands down. Marc And Wally have got it going on. they literally pulled a rabbit out of a hat with my truck. Yes! it is expensive! Yes it is worth it! Yes I would do it again! if you compare dollar for dollar what you get with other " tuners" this is an absolute no brainer. Proud to say I was able to join the 400HP club with their help! Book your appointment with these guys, and unleash the true potential of your vehicles engine. Way To Go International Dyno Authority!
