Any benefits to this?

I know you can fit a sacer to a standard plenum but what about on a RS500 one?

 

I run this on my motor circa 700bhp on race fuel, not sure at what point their is benefit.

 

I thought yours was 4 injectors?

Or have you got t'other four blanked off?

 

he only runs 4 injectors.

the important bit is the plenum and throttle as they are much bigger than standard

 

But was running 8 at one point i belive and that maybe the point hrod is on about i heard 1 benefit to the mapper it will need remapping

 

the car will need remapping if you fit the plenum spacer as there will now be more air.

rod used to run the 8 set up on his old 500 bhp engine but dont think he used the spacer then??

IMO the spacer is only worth while over 550bhp
