When did the TUNED PORT INJECTION come out?

What Is a Tuned Port Injection? Chevrolet’s version of multi-port fuel injection called Tuned Port Injection was introduced to the public in 1985 on the Corvette and Camaro. Featuring tuned length intake runners, one individual injector per cylinder ( multi-port), and mass airflow sensor fuel management.

When was multi port fuel injection first introduced?

Chevrolet’s version of multi-port fuel injection called Tuned Port Injection was introduced to the public in 1985 on the Corvette and Camaro. Featuring tuned length intake runners, one individual injector per cylinder ( multi-port), and mass airflow sensor fuel management.

How does a tuned port injection pump work?

This pump supplies 35 psi regulated fuel pressure to the Bosch style fuel injectors, and enough volume to handle all the requirements of the engine while under load. Unlike batch fire injectors, these injectors are not opened several at one time, but one at a time to allow more precise control of air fuel ratio.

What kind of port injection does a corvette use?

The system was initially designed to help the smallish 305 cid engine with a boost in low and mid range torque, and quickly adapted to the 350 cid engine found in the Corvette. The venerable TPI system proved to be versatile and tunable, and is now a mainstay for hod rods and street rods alike.

When did the Chevrolet 305 V8 engine come out?

As America faced an energy crisis and the government began to regulate a car’s emissions, General Motors made adjustments to many of their small block, V8 engines. GM introduced the Chevrolet 305 engine in 1976 to provide a smooth driving performance while allowing for lower octane fuels and lower emissions.

What should fuel pressure be on a TBI fuel injection system?

Fuel Pressure is critical to the operation of a fuel injection system. Always check to insure that you have the proper fuel pressure. Fuel pressure should be a constant 10 – 15 PSI on a TBI fuel injection system and is typically around 12 – 13 psi. Higher pressure than 15 psi indicates that there is an issue with the installation.

Is the Chevy Camaro TPI 305 still available?

The TPI 305 could only be ordered with a four-speed automatic transmission. In 1986, emissions regulations and a resulting revised camshaft profile resulted in a net loss of 25hp from the TPI engine. The L69 still could be ordered, but GM quietly killed that very early in the model.

What are the torque numbers for tune port injection?

Run on the dyno with long-tub headers, an MSD distributor and Lucas synthetic oil, the tune-port injected small block thumped out some pretty serious torque numbers. As expected, the long-runner TPI system excelled at low-speed torque production and offered 501 lb-ft at 3,900 rpm.

Do you need a tuned port fuel injection unit?

Tuned Port Injection units that werc originally marketed for use on 350 CID engines must use an ECM calibrator prom (Mem-Cal) matching that size of engine. TPI units marketed for 305 CID engines must use a calibration prom matching that model engine.

When did the GM port injection system come out?

BUY A TPI SYSTEM The first production TUNED PORT INJECTION (TPI) appeared on General Motors vehicles in 1985. The GM vehicles built with these systems were Corvette, Pontiac Firebird & Trans AM, and the Chevrolet Camaro.
