P-38 small-block Ford gets stack induction
The operational benefits of this new sequential stack-induction system include smooth, fast and dependable engine response during rapid throttling, easy and reliable hot or cold starting, and admirable fuel efficiency. Naturally, the system ends all choke operations, generally necessary on carburetor-equipped engines when cold starting.
Available in individual components or as a fully assembled kit, Kaase’s new stack induction arrangement also delivers precise cylinder-to-cylinder air-fuel distribution to any Windsor-based small-block Ford.
This kit comprises an intake manifold with concealed plenum, 50 or 52mm throttle bodies with attendant linkage and bell stacks, fuel rails with correctly sized injectors, and wiring harness with ECU and sensors. These sense air and water temperatures, manifold absolute pressure, and throttle position. The plenum has sufficient vacuum ports and capacity to accommodate an idle control motor, fuel pressure regulator, power brakes, PCV, and other essentials. Most importantly it offers a range of tuning possibilities beyond the imaginings of the conventional carburetor.
Injectors are selected by the following simple formula: HP x .5 (naturally aspirated) (or .6 for supercharged or .625 for turbo charged) and divided by the number of cylinders. This figure is then multiplied by .9, which represents 90 percent of the duty cycle. For example if a naturally aspirated small-block generates 520hp the correct injector output can be calculated by multiplying 520 by .5 which comes to 260 and then dividing it by 8, which gives us 32.5. By multiplying this value by .9 our injectors should dispense 30lbs of fuel per hour.
Kaase debuts P-38 cross-ram for Windsor
A quick glance at Kaase’s new P-38 cross-ram induction system for Ford Windsor engines immediately conveys two things: its potential to deliver impressive low- to mid-range torque and its inherent low-profile presence to add greater hood clearance—qualities that are often highly valued.
Depending upon the specifications of the camshaft and the cylinder heads, the cross-ram’s lengthy runners awakens the engine’s torque production and induces its best driving characteristics from around 2,500 to 6,800rpm. Increased low- to mid-range torque also promises superior off-idle performance, strong acceleration, and rapid recovery during gear changing. Improvements in fuel economy are a further bonus.
Functioning with factory-style and aftermarket cylinder heads as well as race heads, Kaase’s new cross-ram system is available as a fully assembled kit or as individual components.
The complete engine management system, comprising ECU, sensors, injectors, and wiring harness, is tailored to operate efficiently with a high-flowing intake manifold. Nothing undermines the legitimacy of effective electronics more than the meager flow rates of an inadequate intake. The manifold is also complete, incorporating fuel rails and trumpets. The rails are positioned on top of the intake runners; the trumpets are attached to the ends of the runners.
Finally, Kaase’s P-38 cross ram is supplied with an electronic control unit that has the ability to manage a wide variety of accessories for street use and for race cars. It offers almost infinite tuning and is furnished with built-in data acquisition and diagnostics. By featuring individual control of spark and fuel, it provides accurate fuel metering for quicker response, peak power and torque as well as fuel economy.
