Porting Update - ZR-1 Net Registry Forums

LGAFF · 01-03-2008

Thought I would give everyone the update on porting project. I have learned a few things. I did the intake plenum with a dremel soft metal attachment on a flex shaft. This was great for the short turn and immediately inside the runner opening. It was not good for hitting the long turn due to the angle, and left some small marks, which I am going to clean up with a flap wheel later. If I did this over I would focus on using a flap wheel or other device on the long turn as the material removed is minimal.

After roughing everything out I went back, and used a barrel sander on a drill to try and keep everything "rounded" and symmetrical, this worked well. Finally I took some sandpaper and hit the short turn radius leading into the plenum body using my fingers. Both the drill and dremel worked surprisingly fast.....WD40 or grinders grease doubles the speed with which material is removed. I should have everythng cleaned up by the weekend.

Here are a few few photos.......hopefully I am not a total hack.

1)Photo of runners: note I have not flushed the material out of the body as of yet

2)This is the 36mm fooseball in the runner.

3)Straight shot down the runner, notice the long turn has a few "gotcha" spots I am going to hit these with a flap wheel to smooth them out

4)This is the one spot to watch out for, the material is thinner here than in other areas, I have one spot I am going to have some material added

Let the flaming begin.
