DIY port and polish TB

[MikeG]

I decided to port and polish my TB

Here you can see the factory lip


I started working from the edge to the inside with 60 up to 2000grit on a dremel and some old fashion elbow grease




Here you can see how much I took out. I went with what I was comfortable with.





Finished


This is just to show you what I did. I take NO response abillity if you try this and jake up your TB.

Thanks for looking Mike.

Notice any difference?

 

[MikeG]

It's no neck snapping difference but yes.
I have a smother idle.
A lot better throttle response.
And it pulls harder in the upper RPM's
It was well worth my 3 hrs. of work.

Nice work. I'd like to give this a shot this summer on a spare if I can find one.

Nice!

By the looks of it that's not the first thing you've ever ported/polished,lol.

You do nice work,looks really good

 

[MikeG]

Thanks guy's
I have to pull the TB aging this week so I can half shaft it. I didn't have and replacement screws for the blade.

I think I'm going to get done cutting compound and polish it to a mirror shine.

Believe it or not that is the first time I've ever ported anything.

 

[Hornet]

For a first time,that's very impressive.

Putting a mirror shine on it,is a good idea .

I'm impressed,you've got some talent,lol

I was gonna suggest polishing compound! You're one step ahead. I may try this.

That's awesome, I wish I had the knowledge and skills to do a DIY project like that. Good job!

List the tools and parts needed so others can give it a try.

I used a 10,000 rpm dremel with sanding bands. I started with 60, 80, 120, 200 grit. Then by hand I went to 400, 800 grit then wet sand with 1,000, 2000 grit and finished it up with a felt buffing wheel on the dremel using 3M extra cut compond and glaze for paint.

I know it probably not the best method but its what I had in the tool box. I also know its not as good as a Moe's TB but I like the be able to mod my own parts and not just buy them. And if 3hrs of easy work got me just 2-5hp then I'm happy.

i commend you sir! i dont mind venturing off to try new things on my own but im not the type to mess with something like this. not on my daily driver anyways.

 

[Hornet]

Nothing wrong with your workmanship.

Don't discredit yourself,you did a very good job,and i dare say,your throttle body will hold it's own against anybodies.

Thanks guys. But I still need to half shaft it.

 

[MikeG]

After driving all day yesterday and this morning it seems to not take as much throttle to drive and pass. So far I'm happy with it.

I was going to ask you if that was something you were planning on.

This is a nice cheap way to get some power... I can't see spending 350 bucks on a new one. I spent 380 bucks on a highly modified intake and TB for my G8 and then I send in my stock units and get my 425 dollar core charge back. To me it's a no brainer!

 

[MikeG]

Yeah I'm gonna half shaft it. I didn't have any screws to replace the ones in the shaft with.

I think on my G8 he just mills the areas between the screws and the sides and between the screws, but leaves the OEM screws in there and re-loctites them.
