What is Chassis Dyno Tuning And Why Do I Need It?

How To Get The Most Out Of Your Dyno Tuning Session?

Dyno tuning can offer a great return on your investment and when done correctly, will extract every last bit of horsepower out of your engine. There are two kinds of dyno out there. The engine dyno and the chassis dyno. A few years ago dyno tuning was only done by race teams with big budgets who could afford to run there engines on a engine dyno. To do this is a very expensive because the engine is run separately from the car requiring special mounting hardware, exhaust, fuelHonda dyno Tuningand cooling hookups. All of this special requirements make engine dyno expensive and time consuming.

The Dynojet chassis dyno was introduced a couple of years ago as a low cost way to dyno test high horsepower ouyput cars. The Dynojet Chassis dyno uses computer to measure the amount of time that the engine takes to spin a large, heavy (2-4 tons) roller up to speed through gear range from near idle to the red line. The way the chassis dyno applies the load reduces the chance of wheel spin and that makes Dynojet readings easy to repeat and very accurate. It is easy to repeat runs under the same conditions that vary within one horsepower.

Buying chassis dyno time is fairly cheap. Most shops charge $100 per hour if you do your own wrenching. It may sound like a lot of money, but you will get your money worth in "found" horsepower. Here are some basic chassis dyno tuning tips to get the most out of your session time.

  • Have a plan of what you are going to adjust and learn how to do it. You do not want to be figuring out how to adjust cam timing or fuel pressure when the clock is ticking. The beast thing to do is to practice in your garage, do a dry run before you get to the dyno.

  • Bring your tools and make sure that you have the right tools. Most places will not barrow you tools. Make sure you have a torque wrench if you are going to adjust the camshaft (s) timing.

  • Change or adjust one thing at a time. Make sure that you write down on a paper all the changes and results.

  •   Many shops will not let you work on your car while on the dyno. To make the most out of your time, write down what adjustment you are intending to make and show it to the dyno technician before you begin. Another alternative is to hand your car to a shop that will tune it on a chassis dyno for you. It will cost you a little more but it is a good idea if you are not confident making changes and adjustments on your own.

  • Most shops will make you sign a waiver saying that they are not responsible if your car blows up on the chassis dyno. You would have to do something extremely wrong for this to happen. Chassis dyno tuning is fairly safe.

  • Whatever you do make sure it is safe for you and your Honda Acura car first.
