For use on Tunnel Ram engines.
The ability to change flow rate automatically may be the best
feature among many. When in n2o mode, the system is
running in NA mode until the throttle is wide open. Nice.

Want to qualify with n2o but race without nitrous?
Flip a switch and the nitrous is deactivated.
Example: Qualify with n2o, flip switch, run eliminations NA.

You can also wire in a delay box, on/off timer or button to
use it as a top end charge if you desire.
Air operated Airnoids are the heart of this system.
They are as bullet proof as it gets, offer more flow
rate than any electric solenoid and can stay
activated all day long without failure.  Airnoids offer
a much longer life than any electric solenoid before
the sealing piston needs maintenance. Perhaps
never if you don't run a rock through them.
Installing a conventional wet Fogger system on a Fuel
Injected Tunnel ram can be a nightmare due to all the
lines already in place. It's also a pain to work on in the
pits. There is also the question of different fuels burn
rate. There is a superior, less complicated way.
The NitrousCharger is a dry system.
The extra fuel required is supplied by the Mechanical Injection.
The injection will go richer on demand via the Nitrous Charger circuit.

NitrousCharger Nitrous Oxide System for Alcohol Fuel Injection
The NitrousCharger is suitable for the alcohol fuel injected Top Sportsman, Top Dragster, Quick 8 or bracket car that needs that needs to step up.
The NitrousCharger is  a "bolt on" for the Edelbrock, Holley and Dart Chevy Tunnel Ram manifolds. We can  adapt it to other manifolds, sheetmetal, Ford, etc.
We will likely need your manifold or the top plate in these cases. Call to discuss your application.

The NitrousCharger is much simpler, lighter and easier to work with than electric wet systems. Alcohol is way more forgiving and makes more power. Electrical demand is a miserly 1 amp and could be run with a 9V battery if you so desired.

These are set up based on your current fuel injection combination.
We will email you a question sheet to fill out.

Note: While Enderle hat names are listed, any Blower hat from any Manufacturer is acceptable for use as a TR hat. Hilborn, Waterman, Crower, Fowler, Gorr, Gerardot, etc.
We may need these other Hats/throttle bodies and manifolds on hand to verify fitment of various pieces.

Koffel and sheet metal maniifolds: We need your top plate as these are one off bolt patterns.

Customs: We need your complete manifold/MFI system to implement the Nitrous Charger.
Any combination not listed as "In Stock" are made to order.
10 - 20 working days delivery time so plan accordingly.
Water Grains:
When the WG goes over 100 and the car slows down, increase the n2o flow to compensate.

More often than not you will be more consistent with the Nitrous Charger
