I have noticed that in some signatures that Flats Man and Neal have ported and polished their TB elbow. What is involved in this? I have never performed a mod like this and have no idea what the procedure is.

Does anyone provide a kit of some sort to do this?
Is it worth the time and effort on a N/A engine?
If no kit is available and it is worth doing where do I get the tools?

 

I too would like the procedure on this. I would guess it means removing the rough surface to soothe the air path. I guess you could do it with a series of sandings. How about the butterfly travel. Anyone found that the butterfly didn't open all the way? If so, what kind of a job is it to make it open all the way? Would it be more cost effective to just replace the TB with a bigger one?

Hey kpaton, are you in the Pioneer Valley? I always wonder if there is anyone from around here on these boards.

Wittom,

No, Eastern Mass, 20 miles South of Boston and 20 miles North of Providence RI. I have noticed, however, that there seems to be more lightening owners out here that use this web site than people with modified F150's

Back to the post though, I remember reading that Neal did this and posted pic's of it but he did not go into detail about the process or the tools. Must be one of his mysterious mod's

 

Hi Guys, I will let Neal handle this one. I had mine done at a machine shop along with modding the BBK 75mm TB and the Piece under the throttle body elbow on the Magnacharger. There is a pretty good series of pictures on this subject in my Album which is at the bottom of my Signature. It is not hard to do!

 

Flatsman, based on your experiance, do you think it would be benifical to do what you have done, porting and polishing, with out the mods that you have?
Did you have the shop do it because of time constraints? I would have to do this myself. I couldn't afford to have a shop do it. Do you think it can be done without shop tools. I guess Neal could answer that one.
I like that there are a few things that we can do to get a bit more. I also like that you guys have tried them out already!

Thanks!

 

Wittom, I think when you do these mods it makes you feel good that you are improving something. I doubt that the difference would ever show on a dyno but every little bit helps to contribute to the overall performance of your truck. I feel better knowing that I have done that project and now I move on to something else. It certainly can't hurt anything. Go for it!

 

Many of the the Hot Rod magazines have articles on how to port your own stuff. I personally, would rather have a machine shop do it, like Flats Man did...you know it will be done correctly. On the other hand, I've given my 16 yr old his first car... 89 Firebird with a 2.8 engine... the first thing he did was buy a set of heads from Ebay for $30 so that he could practice porting with a dremel and other tools. I hope he succeeds, he's in automotive occupational education and he's already started working at a service station. His aspirations are to be a performance engine mechanic/tech...... hmmmmm I wonder where he got those ideas from???
