Closed Loop Dyno & Track Tuning , Consulting Services

We offer unique closed loop Data acquisition and analysis services. When you need to gather specific information, we are able to link information from our Fuel Flow benches, Engine Dynos, Shock Dynos, and Real track onboard data gathering. Linking all these systems allows you gain maximum utilization of your test time. Our portable instrumentation and very high sample rate (up to 3800 sample per second) allows us to acquire information that will advance your program. We can provide you with outstanding insight into the dynamics of your test environment. We have 3 complete on board data acc. systems in addition to a stationary (380mhz) high speed unit suitable for observing very transient events.

In the last 18 years, we have offered proprietary engine development information and facilities to prominent engine builders, component manufacturers and race teams. Our development abilities can offer your team a significant advantage. Call and let us assist with your requirements in a confidential and discreet manner.

Total Tuning Program
If you have a tuning problem, we can help!

Gain the maximum advantage of using a weather station. A strong performance advantage is immediately available with our Total Tuning Program.

Our concept of treating each engine and driver combination as a separate entity has proven superior. 1993 marked the introduction of the Tuning Support Program, and in the last 5 years we have gained very substantial insights into the world of engine, driver, and track combination.

Conventional racing logic says that the team with the most money, best driver and highest horsepower will win the most races. Look back over the past season and you will see that the top 20 fastest cars at National caliber races qualified within 2 to 4 tenths of a second of each other. ONE TENTH of a second can make the difference between being comfortably in the Main event or struggling to qualifying through consolation races. We have a proven plan that is worth a minimum of 3 to 5 Hundredths of a second. In some cases our plan legitimately reduced lap times by 2 tenths of a second. Track conditions, weather, chassis setup, and driver all combine to make precise tuning a very specialized skill. Through our Total Tuning Program, your team can have immediate access to information that is specifically tailored to YOUR requirements.

We assign a serial number to each engine, fuel pump, ignition system, and fuel system for a participating team. We build a dedicated data base for that team and use specific information from each race or dyno session so that we can predict the changes BEFORE time trials and the feature events.

Even the most experienced mechanics benefit from our tuning forecasts. Experience has proven that there are changes that occur, which are so subtle, that they cannot be recognized without the Total Tuning Program.

A team using the Total Tuning Program receives phone support for each event. Specific tuning suggestions for that event are provided. Our program can uncover conditions that will lead to failure if left unchecked. Our research facilities and on track data acquisition provide factual basis for our tuning recommendations. The advice we provide is stable, proven information that will yield substantial performance.

The cost/benefit ratio of the Total Tuning Program is the most effective investment that a team can make. You decide on the basis of our analysis to either conserve your equipment or push the performance envelope. Some engine failures are a fact of life at the top. Winning demands maximum power delivery. While we cannot eliminate all failures, our tuning program provides the information to make the right decisions. Extending the life of your engine, while making competitive power will pay for our Total Tuning Program.

French Grimes has the ability and desire to help you sharpen your edge. In 1958, at 15 years of age, I had my first paying tuning job. Overhead cam road race motorcycles proved to be the first opportunity to provide the winning edge. Work and dedication are what it takes to stay ahead. A passion for understanding started me on this path and that same passion continues today. We can help you understand how to tune to win.
