Great holiday or birthday gift.
"High Horsepower Tuning for Mechanical Fuel Injection for Normally Aspirated Racing Engines"
by Bob Szabo
For set up & tuning.
Not for EFI, carbs, or OEM MFI.
For Sprint Car, circle racing, drag racing, tractor pulling, top speed events,
Land or water racing craft
For methanol, nitro, ethanol, or gas
Gas on the street section
For stackers, throttle body, hat type MFI.
Adding a high speed bypass the correct way
Fuel curve flat lining, nozzle velocity, Engler stumble valve, Kinsler diaphragm valve, AFR
Baseline setup and tuning for weather,
Supplier approved.
