Thought I would share some pics of the port job I just did on saturday. I took my Muse Motorsports manifold since my car is apart and decided to gasket match it and clean up the runners. I have higher res photos at home but these are from my phone.

It's a bit more polished now, but I don't have those pics here. Enjoy, questions welcome.

 

Great work there, lots of material needed to be removed.

 

Thanks

 

not bad

 

I'll have to get some of the better pics up later on. I smoothed it out some more after I took these and it looks bumpier than it feels in person. Guess I could have polished it up a bit better, heh

 

You know the gasket is way bigger than the actual runners coming out of the head, right? Taking away too much material could potentially be a bad thing. Then again, it looks bad ***, so game on! I like the use of the big clamp!

 

Yeah I know, but I figured if I matched it it should be ok, plus it was the only way I knew how to do it uniformly. and it looks cool

 

Yeah but you always want to transition into a larger area to create a funneling effect versus the air clipping an edge smaller then than the area it is coming from. As long as you didnt go larger than the gasket size you cannot hurt the flow.

 

Also good to know I made sure to still make the runners taper down gradually towards the collector so it should have a nice funneling effect there as well. It was surprisingly easy and fun to port it, I gotta say.

 

Now your exhaust manifold ports are much larger than your head ports...do you think that is a good idea?

 

I don't know, do you? Seems like I'm getting mixed opinions here, but I can't see how it would hurt because it's not larger than the gasket.

 

it seems like it would be more turbulent comming out of the head to the port now (at the lip of head/exhaust). i don't know if that's what he means, but i think that might be negligable considering the volume of air your moving.

 

Here is a tip, if air doesn't have to change direction ...don't make it change. Bigger is not always better. Screw the gasket, pretend its not part of the equation....what size should the port be of the manifold be? See what I mean.

 

very quick sketch.

Guess I'm ready for when I get the head ported out then, huh?
