I picked up a Rotary works TB and I am just curious how far you guys have gone into porting the UIM. I dislike all the raw metal in the way of the butterfly. If anyone has any pics of what they did I would love to see them. Have to take this project on asap before powder coating. Thanks in advance guys.

Honestly your better off with stock throtlle body. People actually loose power with that tb. It looks pretty though lol

Awesome thanks. So I always see they just open the top two runners. Is it not a good idea to open the whole thing up so there is zero restriction behind the TB?

 

As for the TB I already have it so I'm going to give it a go

 

Be sure to check for leaks, if I remember correctly they had widespread issues with pressure leaks. I've never owned one though, so I can't speak from experience.

 

Here's mine. Hope it helps.





Just don't get carried away and you'll be ok.

 

And I disagree with this.

 

That is exactly what I was looking for. So it seems to work really well that way?

 

Mine works well. Idles and flows well. I did a lot of work all at once so I can't compare it to anything but I think it does it's job.

 

I believe herblenny also did this modification
