i think you've heard incorrectly.... because i've been active in the forums for a good amount of time and never heard of teardrop porting...
maybe they were describinb the shape of the primary and secondary ports.... its kinda like a crooked teardrop

here we have VWs "teardrop" wheels. maybe they meant that the ports look like them. instead of it being a whole hole, it kinda tapers like the "teardrops" in the rims....

Yea I know about teardrop alloys, I had them on my Jetta. I met this guy at a Mazda meet and he was telling me to make sure that when i port my engine to make a teardrop in the port. I think what he ment was making the bowl part of the port into a teardrop shape when i port it. He seemed to know his $#!+, so I listened. I think he ment someting like teh attached pic. Too bad Ito or BDC are never around anymore...

that's what I was figuring. cause the poeple who've mentioned it have been in the game for atleast 10 years. His exact words to me were, "When you port it make sure you teardrop port it along with the bridge. There's enough meat in the iorns to do both."

Ok, alot of people are messed-up with this one ! Tear drops on the iron plate go right above the port whole's. There not teardrops, there just little hole's that are place on a angle, so with the drill bit it looks like a tear drop. The objective here (Back in the day's) was to get more power without having to have a brideport. So, instead of the BP you have between 3 to 5 hole's on the iron plate's and the engine give's you more power and a very radical sound. It also isn't as loud as a BP but better than a SP. Usally, the secondary are done, but it can be applied to any engine especially when there isn't enough room little on a 6 port engine where you're kind of skeptical to do a BP. I have owned two and had constructed for myself one with this type of application. If you go over to the Latinamerican forum you'll see many that know about it and probably still use it. Again, this was a technic that was used years back !
