Product Details

BOOSTED VS NATURALLY ASPIRATED:

We have lip seals behind the throttle shaft bearings to stop grease from being sucked out of the bearings under high intake runner vacuum. These are turned around on boosted applications so there is no boost leakage and also stops the bearing grease getting evacuated from the throttle shaft the bearings. 


We ask you if you are going to run your engine Boosted, or Naturally Aspirated so we can install the Lip Seals in your throttle bodies in the appropriate way to suit your application.

Since every application of individual throttle bodies is a custom installation, we supply each throttle block with one long and one short throttle shaft to allow you to fit up your specific TPS and throttle linkage system.



THROTTLE LINKAGES AND TPS:


Since every application of individual throttle bodies is a custom installation, we supply each throttle block with one long and one short throttle shaft to allow you to fit up your specific TPS and throttle linkage system.


We are of course, available to consult on recommended TPS and throttle linkages.  Additionally, we can fit both a TPS and throttle linkage system to your throttle block(s) for an additional fee.  Simply let us know how you would like to receive your throttle block(s) and we will accommodate you.


QUALITY ASSURANCE:


Every single throttle bore and throttle plate are measured and matched as a pair to ensure the most perfect throttle fit and consistency across every EFI Hardware throttle body.

EFI Hardware produce 6° Throttle Plates.

 

In the past, 12° throttle plates were the industry standard.  The problem with 12° throttle plates, is that as the plates are moved off the closed position, the change in airflow is huge.  It makes it very difficult to drive smoothly at lower throttle openings.


At EFI Hardware, we only use 6° throttle plates.  This improves off idle and cruise driveability making your vehicle far more enjoyable to drive.



GETTING THE RIGHT BALANCE:


The best idle and cruise quality will only occur when every throttle has exactly the same airflow.


The only way to achieve this is to adjust the linkages and/or idle bypass screws and use a tool to measure the airflow at each throttle.


Getting the right balance is not a should, it is a MUST.
