Im removing these flanges for the extra injectors from the hard pipes and either getting the hole covered or a beaded pipe fitted to run a hose between them for a pre throttle balance pipe.

 

Opinions.......

 

nothing wrong in it .. and it should help with balance of the tubs if anything major happend

less chance of running one side of the engine leaner

 

i did my balance tube using the Bov Ports 35mm in Dir

Ive gone for another balance pipe too just to be on the safe side using a fmic
