Throttle Body Spacer

[fordboy]

has anyone tried one on a 2003 7.3 psd? is it worth the money to invest in one?

[mschn99]

there is no throttle body on a 7.3......so i guess im not sure what you may have seen...

Do you have a link to what you were considering??

[fordboy]

yea here it is http://www.autoanything.com/air-inta...A1851A0A0.aspx

i realize they list it for your truck, but that product will not work on your truck. I dont even know how they can list it because your truck does not have a throttle body......

Even at that, that product will not provide any kind of gains on a turbocharged motor anyway....

it said that it goes in the cold side of the intercooler tube where the tube connects to the y i have a pic but i dont know how to put it on here

[mschn99]

trust me, it isnt worth it!!! you have a turbo forcing air into a cylender, it has no choice but to flow into the cylenders no matter if it is being "spiraled" or not....pressure has to go somewhere if it can, and when the intake valve opens, it has to go into the cylender

Don't waste your cash. Some parts are a crock, that one is one of them

you are wrong and right. the air coming from the turbo is actually generall spinning, as it goes through the intercooler and piping it does loose this, spinning air moves faster, and is less turbulent than tumbling air. you can also more eficiently compress it as you can fit more into an area than you can with turbulent air. how much i can not tell you, but overall, it does have positive benefits.

Where is your proof to back this up on our turbocharged engines?

[jwiger]

he is right about the spinning air, it's all about "laminar air flow", and there is proof that having the air spining into the combustion chamber (just like water spinning down the toilet) does help in making a complete burn, which give you more power per drop of fuel and less emmisions.

Marc is on the right track too, with a turbo, adding volume to your plenum doesn't help, but if you could enhance the actuall runners of the intake then you might have something there. if you spent some time on your intake and were able to reduce the resistance a little (take casting lines out and such) then you could make the same power with less boost, and of couse the more power with the same boost. i'm pretty new to diesels, but not to turbos or general engine performance.

For both intake and exhaust, peek torque RPM is determined by the cross section of the intake and exhaust runners, adding length to the runners helps expand the torque acoss a wider section of the RPM range. naturally asperated and nitrous fed cars can benifit from a large plenum (the open area between the throttle and individual intake runners) because of the pulse from adjacent cylinders working together to help force the air into the other cylinders. this is for the most part not a factor on forced induction (turbo or supercharged) engines.
