The Topgunspeedworks ROTREX C38R Supercharger Kit is a high-performance tuner kit engineered to deliver exceptional horsepower gains. This kit features the Rotrex C38R-112 supercharger, touted as the highest horsepower supercharger kit available, capable of achieving up to 708whp/556wtq while utilizing a filter for engine protection. The comprehensive kit includes the Rotrex C38R-112 head unit paired with a dedicated Setrab 19-row oil cooler, all supercharger mounting bracketry, a Tial blow-off valve, and an in-cabin Boost Control Module to fine-tune power output. It also incorporates a 1000hp Air to Air Intercooler with a Vibrant Core, 3-inch intake piping with MAF housings, a remote coolant overflow reservoir with lines, a K&N cold air intake filter with 3.5-inch piping, and PCV breather filters. Installation instructions are also provided. As a tuner kit, this package does not include injectors, fuel pumps, or tuning software (e.g., EcuTek). Specific fuel requirements and recommended supporting modifications vary based on desired power output. For 91/93 octane, up to 500whp requires 1000cc injectors and a 340lph pump. For higher power levels on 91/93 octane (600whp+), 1200cc injectors and a 450 lph pump with a return fuel system are recommended. E85 fuel support ranges from up to 700whp with 1300cc injectors and a 450 lph pump, to 800whp+ requiring 1600cc injectors and a higher-capacity fuel pump setup (450 or 525 lph with specific configurations). In all cases, a tune is required, with base or remote tune packages available separately. Fabrication and assembly lead times are approximately 8 weeks, with overall fabrication, assembly, and shipping estimated at 10-12 weeks. A 5% credit card reversal fee applies to refunds requested prior to delivery.
