Hey Folks, the weekend is here, and thought I would spend some quality time with the car. Anyways, what you are about to see is not professional by any means, and is almost as backyard as you can get without being in the backyard - lol.
I've been pondering the idea for awhile of trying to do some porting to my intake manifold, and throttle body. I just wanted to match it up to the block as best as I could, not just bore it out to it's maximum which really I don't think that necessary since the flow is restricted by the port holes on the engine block anyhow... This is by no means a how to, I probably did things that were not necessarily the proper way, but thought I'd share for fun anyhow.
BTW: If you ever do this, WEAR A DUST MASK an EYE PROTECTION - aluminum dust baaadd, mmmmkay?
Anyways, here we go...
1. Here are pics of the tools involved in this Friday night project... not shown in the picture are a air compressor, a good vice, and my slave monkeys.
2. Close up of carbide bits used for material removal. I used my rotozip, instead of using a airtool.
3. I just used a pencil and a piece of paper to take an imprint of the port holes on the block as a reference...
4. Here you can see the difference between the openings by the stencil. The holes are 1"3/4 on the manifold, and closer to 1"7/8 wide on the engine.
5. Here is the intake manifold in it's stock form.
6. Here you can see how the far left two holes are coming along compared to the untouched third opening on the right. At this point I'm about 2 hours into removing material. I'm slow... but it's really easy to take off a chunk that would be a disaster if you are not careful.
7. Progress picture..
8. More progress.. 6 hours now...lol. In the picture it looks rough, but its super smooth to the touch - I think it was my Dremol sanding that made it appear rough, I don't know. I took more pictures but they didn't turn out of the interior of the runners. I ported as far as my bits would go, I think they are about 6 inches, but most of the material was removed in the first 2 inches since it bottlenecks the most there anyways. It seems to open up more as it goes inside. Also ported the throttle body side just slightly for the spacer and the intake manifold to line up nicely.
9. Measurement. 1"7/8
10. Ok, on to the throttle body. this is in it's stock form.
11. Ported.. 1.5 hours after. It's really hard to see the difference, but believe me there is. The stock TB tapers in greatly right before the "flapper". You can see it better in person, and you can definately feel the raised restriction with your fingers. Now the opening is nearly straight through, but I left anything past the butterfly valve untouched so it seals proper.
12. Now, the clean up. I think I left about a 10 foot circle of aluminum shavings on the floor, the other half was in my clothes and hair. Fantastic!
13. After cleaning up and losing a pound of aluminum shavings in the shower, I sanded and took off the cast lines on the exterior, and painted the piece up!
14. Close up of my homemade Mopar emblem for a finishing touch...
15. Installed again...
Other side notes:
*I spent at least an hour cleaning the parts of any misc dust and shavings trapped inside with an air compressor and running cotton rags back and forth inside until all the junk was gone. Don't even think about doing this if you can't get it cleaned out after.
*I also discovered that WD40 is your friend since your bits will get full of aluminum chunks. Spray on some, and the chunks come out when you start grinding again. I even sprayed a bit on the area being ported and helped cut nice.
*Let the tool slowly cut, and do not force the material removal.
Thanks for taking a look! Was fun.
Update:
Took the car for a run, and did notice a difference. The car seems to spool up quicker and pulls harder than before. Not a HUGE difference but an improvement all the same. When I press into the pedal it responds quicker. I guess it worked for me!
