Pipercross Viper Dyno/Rolling Road Test
Standard Air Box
Pipercross Viper Air Filter Fitted
Before
After
A
5hp gain at the wheels or a 7% gain in power. On the road the car felt a
lot more responsive, was more willing to rev and was better to drive,
all in all a modification well worth the effort. Looking at the graphs
it can be seen power drops of significantly after 5,500 rpm, this could
well be down to the standard ecu. We will reprogramme or replace the ecu
at some point and see how much power we can get, if we can get the power
to keep climbing up to the limiter we could be looking at 120bhp at the
flywheel or 90bhp at the wheels.
