Can you run Hilborn injection on street?
These days, Don says, Hilborn strongly recommends using the latest electronic fuel injection that looks almost identical to the early style, but with modern injectors that make for trouble-free street driving.
How does Hilborn injection work?
Hilborn’s fuel pump has an inlet and an outlet side. On the outlet side there are three ports. One feeds the injectors; the other two are available to bleed off (or return) excess fuel to the tank. All systems use the second outlet, called the primary return or main bypass.
How does a barrel valve work?
A barrel valve or metering valve controls the appropriate amount of fuel for starting, part-throttle, driving, and stopping. A barrel valve is also used to throttle the fuel for part-throttle driving. Most barrel valves have a very simple spool or metering cylinder inside of the valve for controlling the fuel flow.
What is SCPI fuel injection?
Our Multi-Port Fuel Injection (MFI) system has several advantages over the original Sequential Central Port Injection (SCPI) system, including port fuel delivery and high reliability, better hot starts and reduced vapor emissions, and faster prime on hot restarts.
Are Sprint cars fuel Injected?
The cars have 15-inch (380 mm) wide right rear tires and 410 cubic inch engines with mechanical fuel injection. These sprint cars have no batteries or starters in them, necessitating push starts by a quad or truck.
What’s the difference between MFI and EFI?
MFI = multi-port fuel injection (a separate fuel injector for each cylinder); EFI = electronic fuel injection (injectors controlled by microprocessor, electrically rather than mechanically activated).
What is multi-point fuel injection system?
The MPFI is a system or method of injecting fuel into internal combustion engine through multi ports situated on intake valve of each cylinder. It delivers an exact quantity of fuel in each cylinder at the right time.

What is better GDI or MPI?
Compared to conventional MPI engines of a comparable size, the GDI engine provides approximately 10% greater output and torque at all speeds. In high-output mode, the GDI engine provides outstanding acceleration.
What are three types of fuel injection systems?
What Are The Different Types of Fuel Injection?
- Single-point or throttle body injection.
- Port or multipoint fuel injection.
- Sequential fuel injection.
- Direct injection.
