3" inlet to the Turbo ok, yes, that's the pipe going from the filter to the turbo. Big here is fine, as the turbo is pulling in air, and you don't want a restriction. Same for exhaust after the turbo, you don't want a restriction after the turbo.
Now for the exhaust going TO the turbo, you don't want 3" as that would reduce velocity and spool time would increase. Same for output of the turbo. The output of the turbo isn't going to be 3". It doesn't need to be as big as N/A because it's under pressure. It's on the output side.
The INPUT side needs 3". Such as the INPUT (air filter side) of a turbo, or roots style S/C where the TB is the first thing, such as N/A. The reason being is you don't want to make it hard for the device to suck in/breathe in. After it has breathed in and compressed the air making the output pipe of that excessively large isn't going to gain you anything but a drop in pressure since you have more volume to fill and pressurize now. So you will cause more lag.
I hope that explains it, might be a lot of extra words and not the best but I'm in a hurry working on stuff in between

I would like to bring some things in this thread together to make sure I understand correctly.
When using a 3500 plenum and this adapter:
Then you can bolt on a northstar throttle body(not considering any porting needed to match the bores)? The northstar was 4.6L?
I have seen some recent nortstar throttle bodies and they seem to have bolt flanges on both sides...one side goes to the plenum and the other bolts on the MAF. And the MAF is what transitions into a tube. Are there other northstar throttle bodies that don't have this MAF bolt flange and have the tube transition built into the throttlebody?Wayne

Ben,
If there is real interest, I can make 70mm Vortech (3 bolt) to 3500 planum adapters. I have both here at the machine shop (yes, still working at 1:30am Fri nite) for test fit, I was thinking about using it on my car anyways.Comment
