And Who Said We Only Work On
Mustangs?!?
Mike Kroska brought us this new version of a muscle car classic – a 2006 Dodge Charger Daytona Hemi.
Like most of us, he wanted more power
than Dodge had provided and, in this case, chose nitrous as the source. He had
a nitrous system installed elsewhere but came to us to have it properly tuned
on our dyno. It was running very rich on the ‘juice’ and there were some
install issues. After a few discussions about the best approach to setting up
nitrous systems, he decided to have us make some changes. After rewiring the
system, changing switchology and installing a Wide
Open Throttle (WOT) switch, he now has a system that is easy to control,
reliable and makes awesome power. After activating the system power, spray is
engaged only with the throttle at WOT and at an RPM greater than 3200. Talk
about a torque monster!!
Now, some might wonder why the torque is
so much higher than the horsepower. It’s simple. The dyno measures torque –
period. Horsepower is calculated by the system based on both torque and speed
(RPM). With nitrous, the effect is immediate and peaks at a much lower RPM –
here 3800 RPM. It then begins to drop off as speed increases resulting in a
lower horsepower at peak RPM. Notice the flat torque curve of the
Return to ‘Mopar’
