Rather than discuss the subject on this site it is better if you go to my Automotive Dynamometer pages, as I used to build them! (Below)
Automotive Dynamometer Systems(dynamo meter/rolling soad) information
Once you have built your new motor, or fitted any tuning parts you will NEED to visit a good automotive Dynamometer or rolling road. If you don't you will never be able to set up your engine properly. A good dynamometer allows you to use a gas analyser while under load so you can see the real air fuel mixture at all RPM's while driving.
