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.

Yea, but it's ok.I would have guessed if the author wanted the whole article posted here he would have copied it here.
I do see your point. But it works both ways.I would have guessed if the author wanted the whole article posted here he would have copied it here.
LOL! Yes. You are the originator.....But everything originated from my video.
Ha, just sayin'....
A few years ago Bob showed me that car, and the blower.The car was under an inch of dust in the back room of a machine shop, the blower was in the attic ... The blower was the compressor side of a 101mm turbo and Bob hand built a gear drive using helicopter rotor gears in a custom machined gear box, the thing looks like a modern day procharger, he even has spare parts for it. It was driven via a jack-shaft meshed into the flywheel teeth. Bob was always a forward thinking kind of person.. Phuqing awesome stuff...Well that did happen before. Apparently in 1989 someone put a locomotive centri on a V12 Ferrari Boxer engine in a 308 Ferrari and was banned by the NHRA...

This overpowered brute was originally designed by Bob Norwood for NHRA drag racing. The car ran under the national class record with 7.0’s at 170mph in the quarter mile until its gigantic Vortech-like centrifugal supercharger was outlawed by the NHRA. At this point the car ran a few exhibition drag races and then arrived at Bonneville in 1989 ready to take a massive ram at the world of top-speed racing. Essentially, the car was a tube frame Ferrari 308 designed for Pro-Stock drag racing and fitted with funnycar-type composite body panels. The rear tires were massive slicks mounted on a narrowed Ford nine-inch rear axle—exactly like present-day Pro-stock drag machines. The transmission was a pressure-shifted Lenco unit with nine-inch gears. The front-mounted powerplant was an evil-looking thing surely smuggled into Texas directly from Hell you might guess ran on Plutonium waste or Di-lithium crystals or something much worse. Actually, the 308’s engine ran on 120-octane super-premium race gasoline and was based on a Flat-12 Ferrari Boxer block fitted with 4-valve Testarossa heads, topped with a beautifully sculpted and truly massive air-water intercooler mounted directly on top of the block. The intercooler featured 12 super-high-flow electronic injectors spraying furiously into velocity stacks integral to the intercooler. The massive intercooler unit bolted directly to the heads and functioned as a combination intake plenum/intercooler/fuel rail/manifold unit.
The centrifugal blower—salvaged from a gigantic British locomotive engine that apparently no longer Thought It Could—was driven by a 1.5-inch shaft that traversed the length of the engine and was driven off the flywheel via a reversed Allison turbine helicopter gear-reduction unit originally designed to step down turbine velocities to something the main rotor could handle. The FAA required this type of gear reduction to be replaced after even a single emergency auto-rotation power-off landing, guaranteeing availability at fire-sale prices. The blower, looking like a hugely-overgrown Vortech blower sent back in time by The Machines to destroy all human life in 1989, had a five-inch impeller that was capable of gobbling air at the rate of something like 500 pounds per minute, a rate that could probably suck the air out of double-wide in less than 60 seconds!
The supercharged 12-cylinder Boxer engine, featuring a lightened flywheel and knife-edged crank, and could rev from the engine’s 1200 RPM idle to the 9K redline in just over a tenth of a second, and had been certified on a Superflow 901 engine dyno to make 1400 horsepower on 120-octane gasoline at 60psi boost. The short-stroke 3.2-inch bore engine was upgraded with a billet Crower crankshaft, extra-long Crower rods, custom forged pistons, and was managed by a Haltech F3 EFI controller and a Firepower direct-fire 12-coil ignition. According to Norwood, each 24-valve head was carefully flowed and mildly ported for optimum forced breathing.
In 1989, the flat-12 308 arrived out west in time to make a few runs in Land Speed Record country with Greg Johnson at the wheel. However, before the car got a chance to break the 223 mph record for 5.0L and less blown modified sports cars (1400 horsepower should’ve made this look easy, assuming the car hadn’t already entered a low earth orbit) the event was rained out.
“This may have been a good thing,” allows Norwood.
I saw it under an inch of dust in storage, and the next unit had his 1.0L MR2 (this was about 7 years ago).A few years ago Bob showed me that car, and the blower.The car was under an inch of dust in the back room of a machine shop, the blower was in the attic ...

Its too bad that often in the past the "FORWARD" thinkers or the ones that had brains and talent get pushed aside. Same deal with the Buddy Ingersol showing up with his T type v6 turbo setup to run prostock. He proceeded to go to finals against Bob Glidden. Then his car was outlawed from Prostock.A few years ago Bob showed me that car, and the blower.The car was under an inch of dust in the back room of a machine shop, the blower was in the attic ...

Classic !!!!! Made me laugh for ages.....Now you just have to mock up some tubing and plumb the outlet of the twins into the F3 inlet.....LOL!!!!!Hey Mark. How are you? Give me a jingle. I only call Ryan now a days..LOL Looks like you have been really working this fall. Hope to see you guys when I do my engine builder tour. I kind of liked this idea, but it takes a ton of room. plus more moving parts.

Nothing yet as far as I know. I guess we will have to wait till the PRI show and or Johns in car testing which may well be top secret.....bump
Any more info on this?
