Throttle plate orientation

Post by terryly »

Hello When fitting a throttle body upstream of a 90* bend is there a best practice for the throttle plate orientation ? I am trying to figure which way to position a junk yard throttle body I picked up. How the pressure ducting is going to be set up is Turbo coupled to intercooler then coupled to Throttle body then coupled to a very short legged 90* bend to a"T" and finally on to the left/right intake. I would not think that having the plate open to the side of the 90 would be right so that leaves opening to the inside or outside of the 90* bend. In a dry flow setup {injectors at intake manifolds} may not matter to much. What I am concerned about is when putting a water/meth nozzle upstream from the "T" splitter to have even flow of W/M . Have any thoughts or firsthand with this ? Am I Overthinking this ? Here is some pics thanks for looking

I do believe that you are overthinking it. Just make the sucker fit, make it easy to pull the throttle with a cable and move on. As an alternative to getting all the water meth in and hoping is splits equally from side to side, you could run a pair of half sized nozzles instead. That's what I did. One just before each plenum.
