New from Holley – the NOS nitrous system for 2015-2020 Challenger/Charger Hellcats and 2018-2020 Trackhawks. These systems can deliver up to 250 additional RWHP when desired. See more details below.
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.
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.
