...and a 2500-rpm stall speed converter would be even quicker, since the engine could be held against the brake, preloading the converter, to build usable boost pressure before leaving the starting line.

Other possibilities include running with open exhaust, bypassing the catalytic converter and mufflers for for off road use and substituting premium fuel.
In this mode of operation, the system will produce 9-11 pounds of boost. And if that isn't enough, H-O also has a twin turbo kit that will similarly fit under the stock hood [NEVER PRODUCED]. Other options, such as a waste gate and a compressor mounted water injection system are also available for all-out Additionally for the do-it-yourselfer, the pressure bonnet and Q-Jet modification pieces, the waste gate, the water injection system, the Rajay turbos, and most other kit components can be purchased separately, thus simplifying "blow thru" installations on any vehicle.

Study the accompanying photos and application list. You may find just what you need to "transform" your machine into a force-fed muscle car.


All lines have been routed to clear all existing belts and accessories, including air conditioning.
The heart of the system is the exhaust plumbing and the compact Rajay 301E turbocharger. Note the small hole atop the compressor inlet for attachment of the optional water injection.
Greatly simplifying the installation, is this modified front engine cover. It includes the turbo oil drain provision and a relocated lower radiator hose outlet. Also included is a special lower radiator hose and the turbo oil supply and return lines.

To provide clearance for the turbo exhaust, the right side of the engine is raised slightly with a special motor mount. Raising the engine creates an access problem with the left valve cover, so a modified valve cover is provided to clear the power brake.
On "blow through" installations, fuel pressure must be higher that boost pressure. This modified fuel pump is connected via a pressure line to the carb float bowl to reference pump pressure above boost pressure. The fuel line is also supplied.

This plate is installed beneath the carb to pressurize the modified throttle shaft bosses with dry air, thus preventing a possible leak of fuel-contaminated air into the engine compartment.
