Ported Throttle Body
« on: September 20, 2007, 09:24:57 PM »
Has any one had a ported and polished throttle body fitted to their FD3? Am looking at doing mine. wondered if it was worth while? any good? or where best to buy such a thing of the shelf?

Cheers
Lee

Get a small compressor and die grinder and have a go yourself. As for if its worth while the car will only breath as well as the highest restriction so it depends on the rest of the inlet and exhaust.

Just like that he says!! What am I grinding! and what am I not grinding.. just smooth internals and leading edges of butterfly\'s?

I already have the compressor and tools!

just need to balls if I am going to have a crack myself..

Its easy just time consuming you are basicly trying to smooth out the air flow removing any excess metal you can. I\'m sure one of the fd guys who\'s done one will post up a pic for you but here\'s one of my 20b throttle body to give you an idea. In addition to removing metal i\'ve also removed all the emmisions crap and secondary butterflies, added chemical metal in places to alter the airflow to smooth it out as much as poss.

You will gain top end torque due to volume of air but loose it low down i.e before 3k

I have one for sale here too so buy it and have a play.  Any alteration in the airflow and its smooth passage to the combustion chamber will always get you results but some may not be noticable unless you do others as well.  If you are gonna do anything make sure that you have an engine that not only breathes freely but exhausts it freely as well.  I work on aero engines in the RAF and mainy millions of pounds are spent on improving efficiency of the various compressor sections to gain more thrust.  Mostly on blade dynamics and better and smoother airflow.  In the manufacturing stage they dont give a toss about the castings and its these bumps and ridges that you aim to get rid off......silky smooth but just dont over do it as this too can upset the whole balance.
