6.2L Hellcat head porting.
Supercharged Hellcat — porting lets the blower actually fill the cylinders.
What this head actually flows.
Intake flow at 28″ — stock and ported, both measured on our own SF-1020 flow bench.
| Valve lift | Stock | Carma CNC | Gain | % |
|---|---|---|---|---|
| 0.200″ | 132 | 162 | +30 | +23% |
| 0.300″ | 248 | 259 | +11 | +4% |
| 0.400″ | 303 | 308 | +5 | +2% |
| 0.500″ | 332 | 340 | +8 | +2% |
| 0.600″ | 349 | 355 | +6 | +2% |
| 0.700″ | 349 | 363 | +14 | +4% |
Peak gain lands at 0.200″ lift: 132 CFM stock to 162 CFM ported. It is already up 30 CFM (23%) down at 0.200″, so the 6.2 Hellcat gains through the whole curve rather than only at the top. At 0.700″ it moves 363 CFM against 349 stock.
