With 7,000 miles on the odometer, this 350Z was deemed the perfect candidate to test the newly introduced Edelbrock Nitrous Oxide kit.
Nissan 350Z Engine
With the vehicle strapped to the rollers, the engine was given a baseline run as it produced its largest gain of 231.7 corrected wheel horsepower at 6246 rpm and 222.4 corrected lb-ft of torque at 4787 rpm.

Out to prove the 350Z can produce competitive horsepower without the need for aftermarket components, this vehicle has only had the factory exhaust resonator removed to give it a deeper rumble at higher rpm. " Logging in horsepower figures is a SuperFlow AutoDYN SF1853 dyno. Edelbrock R&D can view multiple data logs as pulls are made with the main controller. " Engine temperatures and ignition timing is under constant supervision during every run using a MAC tools OBDII scan tool. For this particular test, the Z was run at temperatures of 185 degrees Fahrenheit.

Nissan 350Z Nitrous Nozzle
Using two open-end box wrenches, the main nozzle is removed and replaced with the 90-hp jet (42 jetting) for the next stage in our testing.

Stainless-steel jets have an advantage over the standard brass jets that are sold on the market today. With a stainless jet, the chances of corrosion and distortion of the nozzle is significantly decreased. From left to right are the 60-hp, 90-hp, and 125-hp jets. Notice the tapering of the jets as the numbers increase.
Nissan 350Z Wheel On Dyno
Before our initial pass, we loaded the car with some Cool Blue 100 octane to reduce the chances of detonation due to the engine's high 10.3:1 compression ratio. Keep in mind the vehicle's fuel computer remains stock. With the 90 hp (42 jets), we were finally able to crack 300 whp as peak horsepower showed 323.9 cwhp at 5706 rpm and 314.1 lb. ft of torque at 5260 rpm. Check out how straight the line displayed on the dyno pull is from start to finish.
Nissan 350Z TPS
Utilizing the Nissan's factory TPS as a trigger switch when the vehicle is wide-open throttle, the unit automatically lets the nitrous know when to activate and deactivate.

Just because this is a dry manifold kit doesn't mean additional fuel isn't delivered to the engine. Within the passenger kick panel lays the fuel enrichment module sitting just behind the steel support beam. The seven-wire fuel enrichment system is hard wired into the two coolant sensors and two air temp sensors (two go into the ECU and two go into the engine), chassis grounding, 12-volt ignition source and trigger 12 volt (same wire going to the solenoids used as trigger).
Nissan 350Z Nitrous Bottle
With multiple runs made on the same bottle, it was time to refill the unit before we made our final run of the day.

Removing the bottle to refill is a snap, thanks to the engineers at Edelbrock, which have devised a quick-release bracket using rubber inserts to protect the bottle.
Nissan 350Z Nitrous Heat Blanket Install
Although the heater blanket is an optional unit that can be purchased, it is a necessity when looking to create an optimal pass with your nitrous kit. Edelbrock recommends heating the bottle to an optimal 950 degrees Fahrenheit as liquid is converted to inert gaseous form.

Neatly tucked away on the engine compartment firewall is the nitrous solenoids teed off with an optional purge valve kit. " With a tap of the button, the optional purge kit comes alive, spraying liberal amounts of nitrous through the main lines to minimize lag time when the nitrous is activated.
Nissan 350Z Battery Terminal
The nitrous system is powered through a 12-volt source, through the factory battery terminal.

With Nester Cabrera pulling the dyno runs and Dan Chestnut (head engineer for Edelbrock Nitrous Development) sitting with scan tool in hand, both men sat side by side closely monitoring the engine's vitals to ensure a clean run was made with the 125-hp (50 jet) setup.
