Voxwagen
The boys at Technik
Motorwerks were pretty understanding of my desire to have the car
measured on their dyno. After a day of highly tuned Hondas they were
entertained by the idea of running their first Fox. It was also the
first car they had tested with a Child's Seat in it.
I didn't get a chance
to run the car on a dyno when it was completely stock. This is with the exhaust replaced
by a full Techtonics Tuning exhaust and a K&N filter.
1988 Fox Wagon Dyno Printout
I am pretty pleased with
these numbers. The Fox engine was rated by the factory as producing 93
Ft/lbs
of torque at 3250 RPM and producing 81 HP at 5500 RPM. These numbers
would
have represented the output of the motor at the flywheel and not taken
into
account any power loss through the drive train. The car is now
producing
97 ft/lbs of torque at 3300 RPM and 82 horses at 5500 AT THE
WHEELS, not
at the Flywheel.
I feel this demonstrates that the JN code engine was certainly capable
of producing power on par with the other 8V engines of the day. The
85-88 CL engines were rated at 90 HP. The restrictive exhaust that is
stock on the Fox was another way that VW ensured that the Fox was
perceived as an
economy car. With the cars light weight it may have embarrassed the
GTis
of the day if it had not been purposely de-engineered. It was a
conspiracy.
I can hardly wait to see what numbers the engine produces when the Modifications in Phase One are complete.
