LT4 Supercharged 6.2L V8
The CT5-V Blackwing is the most powerful production Cadillac ever made — and RPT Motorsports builds it into something else entirely. The supercharged LT4 platform responds to our staged approach with strong, predictable power gains at every level. From a refined street Stage 1 tune to a 1000 rwhp Stage 5 with a 2650 supercharger and methanol injection, these packages keep the Blackwing's luxury drivability intact while transforming its performance ceiling. Every build is locked in on the dyno with our custom ECU calibration.
