Abstract

An airflow diverter and replacement air intake plenum is disclosed that provides an increase in the air speed and airflow within the intake plenum of an automobile. The increase is the result of providing appropriately sized and shaped apparatus to smooth out the airflow within the plenum and eliminate turbulence that increase pressure within the plenum and cause a restriction of air movement. The diverter is configured in a triangular shape to divert the air from a single input port into two output ports. The apparatus is ideally configured for use in a Porsche, but can be configured for other automobiles and engines.

Claims

1. A flow diverter for use within a plenum comprising:

an air flow diverter specifically sized for installation within an existing “

T”

shaped intake manifold plenum of an automobile configured in a triangular profile to divert air directed onto a pointed apex of the diverter to smooth the air flow onto the pointed apex of the diverter to the tapered ends of the flow diverter to increase air speed and air flow the tapered sides of the flow diverter have dish shaped cross section that maintains a consistent cross sectional area from a single intake of the plenum to multiple outlet ports of the plenum.

2. The flow diverter from claim 1 wherein the side profile of the diverter is configured for use in a circular manifold.

3. The flow diverter from claim 1 wherein the side profile of the diverter is configured for use in a rectangular manifold.

4. The flow diverter from claim 1 wherein the flow diverter is made from aluminum, other types of metal or plastic.

5. The flow diverter from claim 1 wherein taper from the apex of the diverter to the base of the diverter further includes a profile to approximate the cross sectional profile of the plenum.

6. The flow diverter from claim 1 where the triangular profile can be symmetric of non-symmetric.

7. The flow diverter from claim 1 further includes a method feature to accommodate attachment of the flow diverter within an intake manifold.

8. An intake manifold plenum for a vehicle comprising:

an inverted “

Y”

shaped air intake plenum for a vehicle located after the air filter that including a single main air intake port that ducts airflow to two opposing ports wherein the profile of the two opposing ports approximates the profile of the air intake port to increase the air speed and flow through the intake plenum where the cross sectional shape and area of the ducting from the single main air intake port to each of the two opposing ports is maintained.

9. The intake plenum from claim 8 wherein the intake plenum is made from metal or plastic.

10. The intake plenum from claim 8 wherein the plenum replaces an inverted “

T”

shaped plenum.

11. The intake plenum from claim 8 wherein the plenum is configured for use in a Porsche.

12. The intake plenum from claim 8 wherein the plenum allows includes mounting for a larger throttle body.

13. The intake plenum from claim 8 wherein the plenum allows mounting of various sized throttle bodies.

14. The air intake plenum from claim 8 wherein the air intake plenum reduces turbulent air flow within the plenum.

15. The two opposing ports from claim 8 wherein the two opposing ports are substantially the same size.

16. A replacement intake plenum comprising:

an intake plenum for replacement of an existing intake plenum wherein the replacement plenum provides mounting holes for a throttle body different in size than the factory throttle body;

wherein the plenum has a circular inlet that splits into a plurality of circular output parts in a “

Y”

shaped configuration where the cross sectional area of the circular inlet port is maintained to the plurality of circular output ports where the circular output ports mate with existing plenum ducting.

17. The replacement intake plenum from claim 16 further comprises a configuration to improve the airflow through the plenum by providing reducing turbulent airflow.

18. The replacement intake plenum from claim 16 wherein the replacement intake plenum is made from metal or plastic.

19. The replacement intake plenum from claim 16 wherein the replacement plenum is shaped as in inverted “

Y”

with one input port and two output ports.

20. The replacement intake plenum from claim 16 wherein the ports of the replacement intake plenum are substantially round in shape.
