After carefully researching the various manufacturers we decided that the Mustang dynamometer with an “Eddy Current” load controller would be best suited for the type of tuning and testing we are planning. By God’s grace we were able to find a great deal on a three year old Mustang IMP-SE.

This dyno is capable of measuring up to 2,250-hp and for accurate tuning purposes, the SE (Single Eddy current) model provides 600-hp absorption capabilities. This allows us to place an actual load on a vehicle that simulates real world driving conditions. We can even simulate driving your car on any grade hill or hold your car at a steady speed regardless of throttle position. These features are a great benefit to properly tuning any car. Another added bonus is the low-inertia rolls. This allows our dyno to test lightweight vehicles (as light as 1600lbs) that make BIG horsepower numbers.

A word of warning!!!!: To those who have made dyno pulls on other “non-loaded” dyno’s…..

Your peak horsepower and torque numbers WILL read lower on the IMP-SE.

Mustang Dynamometer Corporation has gone to great lengths to ensure that their products reflect accurate real world horsepower numbers. You will find that the horsepower and torque numbers generated by our IMP-SE will very closely reflect the actual performance of your car in the 1/8^th or 1/4 mile racing situations using most common horsepower-to-quarter mile calculators.

If you use the horsepower numbers from our dynamometer and then utilize one of these calculators, your 1/4 mile time should be very close to the calculated ET (assuming minimal tire slippage and no driver error). 

For example Micah’s 1991 EF Hatch w/b18a1 swap, weighing in at 2400lbs with me in it showed 193hp (with a 75hp shot of n2o). The above calculators show a 1/4 mile time of 13.49. The car ran an 8.95 in the 1/8^th . That would “calculate” to a 13.95 1/4 mile time. It was only the second pass I made in his car. The car was on Drag Radials spinning the first 75ft and a rough 2-3 shift. The point being that I believe I could have slipped the clutch a bit, made a clean 2-3 shift and hit the equivalent of the calculated 13.49 time.

As we test additional cars we will post the results to verify the accuracy of the dyno and these calculations.
