tonyv EPC Member Donating Members 1,598 Member For: 16y 18d Gender: Male Posted 29/04/13 07:20 AM Share Posted 29/04/13 07:20 AM Just wondering if this mod is worth doing if you are chasing max power out of a stock looking setup, iv read some posts about it but cant find any sort of results or gains. Il post a pic as an example Link to comment Share on other sites More sharing options...

Impellor Member 835 Member For: 14y 5m 1d Gender: Not Telling Posted 30/04/13 12:23 AM Share Posted 30/04/13 12:23 AM Go for it. Get hold of a manifold gasket(metal) mark with scribe. You will see how much can be taken off opening to inlet runners (3-4mm all round). You can open up the inlet from T/B considerably to match T/B opening, and improve airflow path to 1 and 6. Contrary to the doubters beliefs you can do alot to these manifolds to assist flow.Im not aware of anyone doing a direct comparision, due o the major fark around and time required to chop and change. But from a theroretic perspective to open it up and smooth will increase airflow, by reducing turbulence. Less turbulence = less friction = increased flow efficiency. Also if you go ahead, don't forget to add a catch can. Cheers Link to comment Share on other sites More sharing options...

Have a think about it Link to comment Share on other sites More sharing options...
