NOS Releases New Hellcat Wet Kit


Holley is pleased to announce the release of their new NOS wet nitrous system for 2015-2020 Challenger/Charger Hellcats and 2018-2020 Trackhawks! While the supercharged Gen III Hemi Hellcat engine is potent, NOS felt that it could still benefit from a 200 hit of spray! This new plate fits between the throttle body and supercharger and delivers up to 250 additional RWHP when desired.

05212NOS – NOS Plate Wet Nitrous System:

Add 200+ Rear Wheel Horsepower (RWHP) to the already potent Gen III Hemi 6.2L supercharged Hellcat engine. Engineered & dyno tested, NOS has developed a nitrous system that includes everything needed for an easy bolt-on installation (94mm billet wet plate, mini 2-stage nitrous controller, 12 lb. carbon fiber bottle, Pro-Race solenoids, and all the required hardware). These systems are a bolt-on installation for 2015-2020 Dodge Challenger & Charger SRT8 HellCat, and 2018-2020 Jeep Grand Cherokee Trackhawk.

Recommend 1 – 2 steps colder spark plugs. No projected tip, fine wire or iridium spark plugs. Power levels in excess of 75 HP should use a racing/high octane rated fuel. Power levels of 200+ HP require a fuel system upgrade.
