SDPC SD3816 - TPI Vortec Lower Intake Baseplate

SD3816
Tuned Port Injected (TPI) engines with Vortec heads is a reality thanks to the Performance Team at SDPC. Our engine dynometer tests have shown a 40HP gain with the new SDPC Vortec TPI base plate and stock Vortec heads versus the stock L98 engine. The Vortec TPI base manifold was designed from the original GM TPI intake to be a universal fit for Chevrolet/Pontiac cars (1985-92) that were equipped with factory Tuned Port Fuel-Injection and the cylinder heads have been replaced with the new style raised-port improved flowing Vortec heads from Chevrolet Performance (#12558060).

Description

PERFORMANCE GAINS
In house testing has proved a gain of 40 horsepower over a stock L98 engine. The larger runners of the TPI Vortec Baseplate combined with the excellent flow characteristics of the GM Vortec heads produced 300 hp on an otherwise stock L98 engine. Other modifications such as camshafts, rocker arms and injectors produced as much as 375hp with the stock computer and throttle body. Testing was performed with a MASS Air Flow sensor system.

MINOR MODIFICATIONS REQUIRED
Our TPI Vortec Baseplate is a universal design that we patterned after the original GM TPI Baseplate. Because it is a universal design, you should first test fit all components that bolt directly to the intake and make any required modification prior to final installation. Some modifications may be required of the external components related to the intake and EGR systems.
