I know I've seen it posted on here before but noithing came up in the search. Is porting and polishing the stock TB worth the time? I heard with the single blade its not even noticable. I know on the stock TB there is a large round casting in the middle of the blades. I'm sure that has got to be disturbing the air a little?

 

Try this

 

I did everything to mine except cutting the throte shaft. I guess i should try cutting it too.I dont know how to post pictures or i would post a picture of my shiny throtle body.

 

Thanks x
