Rons Fuel Injection provided MFI throttle body flow data so that we could analyze the power potential of these low cost, simple fuel injection systems. Racing engine sizes and horsepower potentials were determined at these flow cfm numbers for 100% air density, and are included. Rons FI MFI Toilets 3-3/4″ = 1240cfm: can feed 595 […]
Due to popular demand, we can now provide our ProCalc fuel injection jetting calculator already set up to run your fuel injection combination. This special service includes an extensive evaluation of your fuel injection setup and a custom fuel injection manual all about your engine. We have already done different fuel injection configurations, fuels, and […]

Happy Holidays from all of us at RaceCarBook.com! We hope you’re 2017 was great with even greater things to come in the new year.
Engler Stumble Valve A recent provision from Tim Engler is his stumble valve. It is a normally open bypass valve that closes with pressure. Note: Most conventional fuel injection bypass valves are normally closed and open with pressure, such as for a high speed lean-out function.
Blower Sizing Review An example is provided for an 8,000 RPM Roots blower speed. That would be for a blower drive ratio at 1-to-1 on an engine spinning 8,000 RPM. It could also be for a blower overdrive ratio at 1.333-to-1 or 33.3% over for an engine spinning at 6,000 RPM. The 6-71 Roots […]
Restricted Fuel Pump Sizing with Inlet Restrictors Certain racing classes specify fuel pump flow value limits. The common way to achieve this is fuel pump size. However, another way to achieve this is to restrict the fuel pump inlet using a larger fuel pump. When this is done, it cavitates the fuel pump, limiting […]
Announcing the World of Outlaws at Calistoga Speedway, Calistoga, California, Sept 15-16. We are seeing big rigs all around the area transporting Sprint Cars and converging onto this location for top dirt track circle racing.
We enjoyed this event very much. In addition to hundreds of racecars that included many prostreet cars, blown alcohol, turbocharged, and nitro powered racecars, the event featured a P51 fighter plane flyover and a 250 MPH jet dragster. The staff at the Kingdon event also supplied plenty of shaded seating covered by tents, all real […]
This was again a great event, hosted by the Rio Linda Historical Society. Many top show cars as well as custom hot rods that frequent the streets of Sacramento and central California were highlights. The Dry Creek Ranchhouse was the location surrounded by a pleasant rural farm atmosphere with special provisions for the swap meet […]
