When it comes to keeping your engine performing at its best, regular dyno testing is one of the most effective tools available. Whether you’re a car enthusiast seeking maximum horsepower, a racer looking for a competitive edge, or simply someone who values a well-tuned engine, dyno testing provides unparalleled insights into your vehicle’s performance.

Dyno testing, short for dynamometer testing, measures your engine's power output under controlled conditions. Using a specialized machine, a dynamometer simulates driving conditions while capturing critical performance data, such as horsepower, torque, and air-fuel ratios. Think of it as a fitness checkup for your engine. It identifies areas where performance can be optimized, helping you make data-driven decisions about tuning, upgrades, or repai ... read more

You don’t have to be well versed in the automobile industry to know that your vehicle needs a good working engine to get from place to place. When that engine starts to falter, you have two main options: rebuild it or replace it. There are pros and cons to both of these options; each individual will have to determine which is best for his or her particular situation. Option One: Rebuild Your Engine More often than not, rebuilding your engine instead of replacing it can save you money. Of course, this depends on the specific problem you’re experiencing with your engine, as well as the parts you need to efficiently rebuild it and the time it will take to complete the job. Additionally, if you can’t rebuild the engine yourself, then you will also have to factor in the cost of labor. During an engine rebuild, your vehicle’s engine is generally disassembled, and various parts (O-rings and timing belts) are either replaced or repaired. The engine is then put back t ... read more
