Induction

 

Air Intake

 

Modified air intakes, fitted pleated filters behind headlights, 3" inlet pipes from filters into 3" elbow onto intake manifold, now the engine is receiving a high volume of good cold air instead of the preheated air off the radiator.

Modified air intake throttle bodies, machined bore out from 63mm to 70mm, added larger dia butterflies from XJ40.

 

 

Fuel Rails

 

Available from Ed Ward ed_ward@iprimus.com.au

With the possibility of fire from a leaking fuel hose, it was time to eliminate the risk and change to fuel rails. Ed Ward in Melbourne has done a great job fabricating the fuel rails with all necessary fittings, saves a lot of work and machining.

You can use XJ40 injectors, or Falcon EL injectors (reasonably priced from wreckers) 

To obtain a better spray pattern from the injectors, I fitted new injectors that had been modified by Alex Blackson my Wolf Computer man to a 4 hole spray pattern, producing a much finer mist with greater spread

 

 

Pressure Regulator

 

Fitted an adjustable pressure regulator and gauge to enable setting increased pressure of 44psi.
