Porting of the throttle body / plenum

[Turbo6Smackdown]

First off, does anyone here port these? Secondly, is it hard to do it yourself? I mean correctly. I can do it, but I'm not sure how round, and centered it'll be. Any advice?

your just a ball of questions eh?

There is no value to porting a TB by hand.

For the doghouse, blend the forward lip into a smooth short side radius. You can also blend the EGR tower into a smoother short side radius.

I wouldn't just cut the tower off the doghouse, unless you cut the tower out of the lower manifold, too... and that's a lot of work.

I'm just asking for information, on enlarging the intake hole diameters. I want to see if it's something I can do by myself, instead of buying a larger one. I'm doing this research for a future buildup. Sort of a 2nd stage to my next buildup coming this summer.

Are you insinuating that I shouldn't be trying to learn? I have spare time here. Why wouldn't I?

no harm meant, just having fun.

I do the same thing. log on at 6AM and sign off at 9PM - im a TB.Com Lifer.

Remember I'm 7 hours ahead of the U.S. right now so... If it seems that I'm on at odd hours I'm not

I have a tub of new parts that's goin on this car, for an already tried and tested recipe. But before that, I'm having lonnie redo the engine, so I can throttle the **** out of it at the track, (and it stay in 1 piece) and record some findings with different parts, as in bigger throttle bodies/plenums, hemco's vs. power plates, cam's vs. heads, 3" intake tubes vs. 4, etc etc.
This car is going to be my experimental piece. Once I'm done with that, I'll bolt on the basket of parts I have, and just run with that for a while. After a few months, I'll throw on the 2nd stage of my experiment (cam, heads, intake & tb/plenum) and take it from there.
In the end, I want not only a mid 11 second car, that doesn't stress itself out to get there, but the knowledge that comes with it as well. I don't wanna just bolt and go. That's too simple and I won't learn anything from that.

I want to be like grumpy and ungn. I wanna know which piece works, and why. And why some pieces don't work, instead of just taking someones word for it. I wanna see it in action. I'm just anal like that.

Steve Monroe is the Man.

When you enlarge the TB, you need to open the doghouse to match.

As I said earlier don't cut the tower top off the doghouse unless you are cutting the tower out of the lower manifold (or using a power plate). The doghouse tower top can be blended to improve airflow to the fwd cylinders (disregard this if you are going to use a power plate - just have him cut it off)

Man those throttle bodies are nice. mine hasnt been ported but they have been smoothed at the opening and the connection of the plenum to match. I took the caliper and measured they are still the stock 58mm size. Im in the 10s.@ 24psi.
If i had the money i would get a larger TB.

 

[Turbo6Smackdown]

I run a power plate as it is. seems to do ok.

I just bell mouthed the inlet with a hand grinder, then a sanding roll, then a polish on the inside. Still on the stock blade. Maybe I'll try a bigger throttle body down the road but I want to see how far I can go with the stocker.
