In addition, if you change your driving habits fuel mileage may suffer.Ĭan I purchase your supercharger kit without the supercharger? On custom-tuned vehicles with boost levels 5psi and higher, the mpg can vary considerably based on the particular tune you are running. In general, fuel mileage is better but you are required to run minimum 91 octane fuel. What is the fuel mileage like after supercharging?įor stock drive-by-cable models (Ranger, Sport-Trac, Explorer) running the stock tune with only the Moddbox supercharger kit at a 3-3.5psi boost level, a fuel mileage change of +(0-1)mpg City and -(1-3)mpg Highway. The vehicle was tuned by Lasota Racing remotely as per our Tuning Manual using and SCT X4 and PLX AFR gauge. The vehicle tested was a stock 2005 Mustang equipped with a 2.5″ Magniflow Cat-Back exhaust kit and the parts provided in the Moddbox Supercharger Installation kit using a 1994 Thunderbird supercharger. Here is a Dyno sheet from a 8.0psi setup (2.9″ pulley equipped).
Note: Red line is a stock 4.0L SOHC with a K&N cold-air intake kit installed. The vehicle tested was a stock 2005 Ranger 4×4 XLT equipped with only a 2.5″ Magniflow Cat-Back exhaust kit and the parts provided in the Moddbox Supercharger Installation kit using a 1994 Thunderbird supercharger. Here is a Dyno sheet from a basic 3.5psi setup (3.4″ pulley equipped). The oval style blower (89-93) will produce slightly lower boost levels in the top end. *Boost numbers are temporary maximum boost levels you will experience with the rectangular style blower (94/95). Injector MAF & Tune Required, Cooling Upgrade Recommended Tune Required, Injector MAF, & Cooling Upgrade Recommended Tune Required (not required for non-electronic throttle models) Note that all drive-by-wire (electronic throttle models) require tuning at all boost levels. The hp potentials for an engine with stock internals are listed below (based on dynos performed at 400m elevation and tunes). What is the hp potential? Is a tune required?
