JET MAP INFORMATION
Edelbrock Engineering has conducted extensive dyno
testing with the Edelbrock Dry Nitrous System on various
vehicles to ensure the horsepower increase with the
nitrous system is safe and functions as intended. On a
typically stock 1.5L to 2.0L, you can expect the following
approximate horsepower gain:
NOTE: This jet map is intended to be used on a
vehicle running approximately 40 psi fuel
pressure.
On an engine of greater displacement, horsepower gains
may be slightly different.
ENGINE OPERATIONS CONSIDERATIONS:
When used correctly, nitrous oxide safely elevates
cylinder pressures and temperatures while increasing
combustion rate. These characteristics make the engine
more sensitive to detonation. To ensure proper
performance, engine and drive line life, the following tips
are suggested:
System Jetting
Never exceed the recommended jetting! Excessive
jetting can result in sever engine damage.
Fuel Quality
Because Nitrous Oxide is an oxidizer, fuel selection is
critical. Both octane and fuel consistency affect fuel burn
rate. The oxidizer quality of Nitrous Oxide will accelerate
the burn rate, so we recommend a high quality of gasoline.
We also recommend you use the same grade of gasoline
every time you use your Nitrous Oxide system. This will
help to maintain the same fuel burn rate every time.
Ignition Components
Most aftermarket performance chips increase the vehicle’s
ignition timing, which can cause detonation with the use of
Nitrous Oxide. Please consult with your chip manufacturer
on information regarding the compatibility of your chip
with Nitrous Oxide use. Many power programmers
function using the same method. Contact your power
programmer manufacturer concerning the use of Nitrous
Oxide as well. Many power programmer manufacturers
have specific programs for Nitrous Oxide use.
If your vehicle is equipped with platinum type spark plugs,
we highly recommend they be removed and replaced with
the equivalent stardard-type spark plug.
Engine System Upgrades
With all performance modifications, complementary
system upgrades will always serve to elevate the
consistency and longevity of an engine, especially when
using Nitrous Oxide as a power adder. Modifications such
as ignition upgrades, free-flowing exhaust, camshafts,
cylinder heads, and manifolds can all add to the
performance of a Nitrous Oxide injected engine.
