ill say if it gives only a minimal gain but i can do it myself id do it. a couple of horses is a couple of horses and especailly if i dont have the pay to port it then why not.

 

I can see doing it yourself..I dount know hoe effective a dremel is going to be on cast...

I was hoping to draw some attention to someone that has solid information on the actual benefits of porting the 10.5 (other than increased flow and reducing the roughness inside and port matching)...

does porting the 10.5 reduce knock somewhat..if so than its 100% worth it...

 

none

 

$50 for porting the HS , $50 for porting the mani and about $20 shipped Per Nick at Buschur . This was two weeks ago so it might have changed , and this is NOT for the coating .
