DYNO TESTING CHASSIS & ENGINE IS IT FOR YOU?
lay down a plan to follow during your Dyno visit. As an example we have customers who run some form of Dyno testing before tearing down a car for some major upgrade. They are looking to baseline the platform so they have a place to start with when they start testing the new setup. The other reason they test is to The answer is yes if you plan on taking your racing program to the winners circle any time soon. You want to verify they still have what they started with at the first of the season. The key is to have it planned out before showing up at the Dyno shop and stick to the plan. It will keep you on track and not waste your time or the Dyno shops.
Your standard Dyno test session should go something like the following. Show up at the shop unload early and get things prepped to run. Next review your test plan with the Dyno shop operator so all are on the same page. You will need to then move your vehicle into the shop and get the beast hooked up. Once everything looks good take a couple of warmup runs to get all moving parts up to a level temp range. Once the vehicle has had time to cool down its time to take the first two test pulls. You are going to have a cool down period between each set of runs which is determined by how fast your machine can cool off. This is a great time to install the next set of changes. Once again make at least two pulls on each change to verify it is repeatable. Yes this is alot like Work but it will pay off when you are sitting down later to review what you have done during the test session. Now the most common practice at Dyno shops would be to start the run out at something just off of idle and run the engine up to the max threshold/operating RPM. This is great way to look at Max HP vs Max Torque on the system being tested.
Now let us show you another possible option for you to consider when looking for improvements. What we have seen over the past several years is you can ferret out some really nice improvements on any platform using the following instructions. Everything remains the same except when you start to make the pulls. Bring the engine up to 3000 RPM and then let the engine sit there for about 4 seconds before going to full throttle. Once again finish off the pull at the Max threshold/operating RPM just like with the standard version. What you will find is a chart that will allow you to pick out the areas that need to be changed . And it gives you a great way to A-B compare product response time on your vehicle. TechWest Racing Services uses this test version to compare Ignition boxes, coils, sparkplug wire sets as well as many other products.
What's the benefit?
What we found is this format allows you to simulate the area of the RPM range the engine spends the most time. It also allows you to find areas of the HP vs Torque curve that you could improve on. Consider that most of your wasted time is coming off of the corners or off of the starting line. So any time you can save or gain back to your benefit it is worth the time invested. Just consider looking over the past three seasons you have competed in. How many times did the victory and or qualifying position come down to tenths or hundredths of a second difference? That is why we wanted to offer this option out to the racing community. It works give it a try! What do you have to lose but a couple of finishing/qualifying positions. Right?
