Why does "rational thought" happen after I spend a whole bunch of time (and money) trying to make some wild ass folly work?
Think about this now:
If you have an engine that is set up to breathe naturally aspirated.....It makes sense that you do everything you can to try and get each full combustion process for each of the cylinders as efficient as possible. You open the exhaust, you free up the restrictions, you open the valves farther, and keep them open longer, you allow more air into the engine through its carburetor or throttle bodies, you squeeze the incoming air charge harder.
Or....in your quest to allow more air into the engine,....You put a throttle body over each intake port. You give each hole the ability to suck in as much air as is volumetrically possible. You'd be better off by isolating each TB with it's own filter, the reasoning being "Why have 6 2" holes that are relegated to drawing in as much air as each of them possibly can, only to restrict them by putting on some sort of hat, or airbox and force them to get that air via one....3" opening?"
But you have a turbocharger...It forces air into the engine..You have to have a way to direct that compressed air into the (6) 2" openings...and contain it. You have to come up with some sort of box.........That you put over the (6) 2" openings......and force them all to get their air through (1) 3" opening...
What exactly IS the reason for having these individual throttle bodies again?
Other than cosmetics,....It makes zero sense that I continue with these ITB's if my plan includes a turbocharger. A common plenum intake, w/ 6 fully open 2" tubes offer less restriction than the 6 throttle bodies do with their respective throttle blades hanging out in the middle of each of the 6 holes...
The common plenum offers a stronger vacuum reference to the brake booster,..the common plenum shows a more consistent MAP signal to the MAP sensor....
The common plenum is a simpler, solution to a complex situation:
If there is a single 3" hole feeding (6) 2' ports, eliminating any additional restriction can only IMPROVE the overall performance of my combination.
The ITB's will be on the floor by Sunday.
