* Just a note on interpreting dynometer readings. Having an engine dynoed can be a useful benchmark for seeing the gains of performance work. BUT, it is important not to get too hung up on the numbers. Measured horsepower and torque are dependent on a number of factors, like temperature, humidity, altitude, and even the dyno equipment itself. For example, you build an engine and take it to Dyno service A and it makes 65 horsepower. If you took the same engine to Dyno service B and it made 70 horsepower, you'd be pleased. Dyno service C - 75 horsepower. But if you took it back to Dyno service A and it made 65 horsepower you'd be mad. What does this prove? You have too much money to blow on dyno testing for one thing. Look at the above charts. See the temperatures? On the left, 74/94. On the right, 56/70. Certainly can make a difference.
