An online tool to show why your tuning intuition and experience has always worked!
For the mechanical fuel injection racer/builder/tuner. Determine best power jetting for various racing engines: unblown or blown drag racing, sprint car, circle or drag boat, top speed racing or any racing that uses MFI for ultimate power needs.
-- for normally aspirated, blown, or turbocharged racing engines
-- for methanol, E85, nitro fuel mixtures, racing gas, or gas hybrids.
-- from 1 to 8 cylinders
-- from 1 to 4 nozzles per cylinder
-- main bypass, high speed bypass, plus additional bypass for another high speed or pump saver or stumble valve
-- determines precise jetting adjustments for altitude or weather changes.
Also creates neat MFI jetting records to organize your tuning reference.
The tuner can develop an air to fuel ratio map with this calculator to mimic the fuel management capability of EFI. In addition, the tuner can develop a fuel pressure map with this calculator to go beyond the power making capability of EFI or most any carburetor setup.
"The calculator does what no one person can do...unless you have thirty plus years in racing and know over 1100 computations. Get it right every time..." Mike Shriver, Speedsports, expert tuner for fuel injection used in drag, sprint car, & Bonneville racing.
Sold as a one year subscription. A free 30 day tryout is available.
