No matter what aftermarket engine accessories you have for your engine, whether they are simple modifications, or major add-ons such as a turbo, supercharger or nitrous, tuning plays a major role in bringing them all together. The best results from proper engine tuning can be found when using a dynamometer or dyno for short. A dyno is used to read horsepower and torque curves across the engine’s rpm range at the drive wheels of a vehicle. All dynos have a set of large drums that the vehicle’s drive wheels roll on when making a dyno pass. When the car is brought up into the RPM band and through the gears the machine measures horsepower and torque readings electronically from the load that is put on the drums according to the rate of acceleration of the cars drive wheels. Most measurements are made when the car is in third or fourth gear to give the best results.
A group of Volkswagen enthusiasts from San Diego got together for a dyno day hosted by The Dyno Shop in Santee, California. The cars were all tested on a machine known as a Dyno Jet, which measures the horsepower from free spinning drums, instead of a load bearing system which uses magnets to put a load on the drums the higher up into the RPM band a vehicle’s drive wheels go. Seven modified VW’s took a shot at the dyno to see what kind of horsepower numbers they were putting down and to see if the modifications to their engines were actually creating horsepower. The friendly and knowledgeable staff of Mark, Alex, and Derrick was on hand to answer any technical questions, or to explain what certain readings meant on the display screen. The added bonus with the Dyno Jet system at the facility is the car’s air/fuel ratio is read as well during a run by the computer, to see if anyone might have a too lean or too rich condition that could be causing a loss of horsepower and torque.

Out of the seven participants three of the cars were naturally aspirated meaning they were not using a turbo, supercharger, or nitrous to create more horsepower. In the naturally aspirated camp taking top honors was Brendon Prout with his Volkswagen R32. The R32 has an electronically controlled rear differential, which was disconnected, and readings were taken from the front wheels instead of all four. Brendon successfully laid down 235 horses with 220 ft. lbs. of torque.

The power adder group was the cars using either a turbocharger, supercharger or nitrous to create added power. Jesse Padilla and his MK II GTI took top honors of the meet. Sporting a 16-valve 2.0 liter four cylinder using a turbocharger and nitrous oxide combination to reach his numbers. The turbo being used is a Garrett T3/T04E boosting air through an air to air intercooler which is kept cool with an NOS intercooler sprayer as well as an added 80 shot single fogger nitrous shot into his intake. Jesse laid down 414 horsepower with 372 foot-pounds of torque, which can turn tires into smoking mush after a few hard runs.

Some other notable cars on hand were the MKIV Jetta owned by David Trecha, using a Stage III APR turbo upgrade on his 1.8 liter turbo four cylinder, put out 275 horses with 261 foot-pounds of torque. Another VW R32, owned by Jeremy Nagelberg, using a Stage One VF Engineering supercharger on 7 pounds of boost made 301.6 horses at the front wheels with 242 foot-pounds of torque. Soch Naungayan had a MK III Golf on hand using a 2.0-liter 16-valve four cylinder with a built head and individual throttle bodies naturally aspirated, spun the wheels to the tune of 186 horsepower with 152 foot-pounds of torque.

This event gave European car enthusiasts and opportunity to utilitize a tuning technique that is sometimes over-looked when high-end motors are built. Everyone gained more knowledge on their car’s engine performance as well as some insight to what modifications have helped them gain more power across the RPM band. See the chart below for the full results of everyone that made a dyno pass. Thanks again to the staff at the Dyno Shop for making this happen and for answering everyone's questions.
