Last year at PRI we debuted photos and details on ProCharger’s new F-4 supercharger that is designed for Pro Street/Mod level racing. The problem is, last December was the last we heard about the F-4. Finally, after nearly a year of waiting, some testing data begins to surface on the new supercharger. The testing project has been headed up by none other than 2008 Pro Street champion Mark Micke. Micke, who has taken a leave of absence from racing, has turned to tuning and building Pro Street rides. Micke has been working closely with NMCA Pro Street new-comer John Sullivan in the ex-Scruggs Dodge Stratus. Sullivan’s car is home to a Brad Anderson BAE Stage 8 engine that has been boosted by a F3R-135 ProCharger.

Rumor is that Sullivan will be getting the new 10,000 RPM revving, 521ci HEMI with the F-4 ProCharger. The F-4 features a 3200+ horsepower, 45 psi-capable, and flows a hurricane-like 5400 cfm. The gear drive system on this blower is the same unit you will find on the F-3, though Micke has said this F-4 configuration, “has a belt on it”. The interesting question is, will it be legal for NMCA Pro Street rules? The current rule’s wording for centrifugal superchargers in Pro Street puts it at not legal, but the final rules have not been determined. The 2010 NMCA Pro Street rules state:
Inlet diameter—internal OD 5.250-inch maximum, impeller inducer diameter 5.150-inch maximum, impeller exducer diameter 8.000-inch, discharge diameter—external 4.00-inch, housing diameter (greatest external diameter of housing not to include discharge)–12.0-inch maximum. Injection of any liquid, gas, or any other substance into the inlet or exhaust housing prohibited. Supercharger compressor wheel must be constructed of cast or billet aluminum.

The Specs on the F-4 ProCharger
Volute Diameter: 16-inches
Max HP: 3,200+ HP
Base NA HP: 900-1,400 HP
Max Flow: 5,400 CFM
Max Boost: 45 PSI
Inlet Hose Dia: 7-inches
Inducer Dia: 6.32-inches
Exducer Dia: 8.89-inches
Outlet Hose Dia: 5-inches
Outlet ID: 4.26-inches
Max Impeller RPM: 55,000 RPM
Internal Step-Up Ratio: 5.63:1
As you can clearly see, with a volute diameter of 16-inches already puts it out of the 12-inch maximum external diameter size, not to mention the inlet and compressor wheel being larger than legal specs. Will the NMCA revise the Pro Street rules or will Sullivan make the change to ADRL? Only time will tell and we will have more information on the plans for their car at PRI.
