Mechanical fuel injection is holding its own against EFI and racing carbs in racing. It is simple, lower cost in many applications, and good for fuel pressure increases for more response & power. One recent application tested racing carbs, EFI, and mechanical fuel injection all on the same racing engine. Another recent application tested mechanical […]
We are now developing techniques using our jetting calculator to set up idle air to fuel ratio for really good MFI racing engine tuning. Idle settings in many MFI racing engines are key to superior performance from engine temperature and off idle response. That is done by adjusting the combination of idle vacuum (throttle blade […]
