Almost done with my LIM / UIM

Honestly, they've been sitting since I got them back from Sho-Shop,

On the LIM, primaries are about 33MM, Secondaries are about 38MM.
The UIM needs more work, the LIM just needs to be polished.
UIM needs some casting marks removed, and I'd like to gasket-match the upper and lower together.













AND GUESS WUT

I know it's a picture of just one side, but wutevs.
I am going to bore the Secondaries out to 38mm (hopefully), and probably just clean up the primary port.
It will take me forever due to my job, but i'll happen eventually.



Here are the Honda VF700F Interceptor carbs I just got done with, picture of a single carb of course.

Apologies if all this seems very standard and ho-hum, I'm excited :laugh:

And how it looked like before I did anything :

I got down to the carb pics and was like, wait WUT? That's a carb :laugh: Then I read your caption and it made a lot more sense.

Haha, that is just to show where I am headed with my Intake Manifolds.

I'm getting much better and porting and polishing.

I do like shiny bits.

Very nice, should be awesome when its done.
Oh, and is that a maxhoned upper that you are then massaging some more?

The ShoShop UIM I had really wasn't bigger inside. Maybe a little smoother, but not opened up.....

Yeah, i wasnt exactly thrilled, its cleaner for sure, but improvements can be had.
I wil be going very very slowly on the uim.
Usually use a stone, but in this case sandpaper rolls all the way.
I need to get the upper and lower to match, the secondary port on the uim is like, just barely 37mm

And if you look at the path right after the throttle body, there is no knife-edge.
That needs to cut and split the air, all the definition was removed when it way max-honed.

the Coug has a ShoSource LIM, its nice. ill know more once im longtubed and do my 24lbers and tuned though

so what tools did you use for this work? end results are nice!

Oh man, air powered tools for a lot of it
But i use a benchtop drill press for polishing. Gotta get the heat into the metal sometimes.
i use sandpaper rolls for most of the porting work.
slower going than a stone for sure, but much less danger to punch through.

I throw up some pictures of my setup this week.

Sub'd. If I can ever convince my GF to let me escape for a weekend, I'd love to come up and give you a hand if you need.
