COMP Cams HRT Blower Stage 1 Hydraulic Roller Camshaft — 2009+ Dodge 5.7L / 6.4L HEMI VVT
COMP Cams HRT Blower Stage 1 Cam — 09+ Dodge 5.7/6.4L HEMI VVT
Most cams are designed for naturally aspirated engines and bolted under a blower as an afterthought. The COMP Cams HRT Blower Stage 1 is the other way around — purpose-built from the ground up for supercharged HEMI applications. It accounts for the boost-driven cylinder filling, the compressed intake charge, and the wider powerband a forced-induction setup demands.
Designed for street-driven supercharged builds on 2009+ VVT-equipped 5.7L and 6.4L platforms — Challenger SRT, Charger R/T, 300 SRT, and Scat Pack variants — this is Stage 1 for those who want to keep manners but want more from their boost.
- Purpose-designed for supercharged / blower Gen 3 HEMI applications
- Hydraulic roller design — no adjustment, no maintenance
- Full VVT (Variable Valve Timing) compatibility — no phaser lockout required
- HRT (High Rpm Torque) profile — broad midrange, strong top-end
- Fits 2009–present Dodge 5.7L and 6.4L HEMI with VVT
- Designed to pair with COMP valve springs (sold separately)
- Made in the USA
Fitment: 2009–2023 Dodge Challenger, Charger, Chrysler 300, Ram 1500 — 5.7L HEMI and 6.4L Apache with Variable Valve Timing (VVT)
Note: Verify VVT status before ordering. Pre-2006 and early non-VVT engines require a different cam profile.
