By adding a trumpet to the inlets you can get a cleaner flow of air so its not all about throttle bodies. It just helps air flow
The plan here is to make a completely new custom intake manifold! The piece in the pictures is the manifold flange, the whole manifold is going to be based on it! Using this piece, i'll try and make a manifold like the one pictured in my first post! The trumpets purpose is better air flow like mentioned, the reason they protrude in the plenum is that the velocity of the air around the walls of the intake is very small, because the friction of the air to the metal is larger than the friction of air to air moleculars. So the trumpets suck air from a clean wave area, almost in the middle of the plenum. Except for this, the runners are going to be totally straight, which helps increase the velocity.So what is the plan here then? the topic says this is a project but it just looks like a half finished plenum or am I missing something? Maybe the project is the plenum? Are you running trumpets too? what car is it for? I did see something about a one or cooper...
Interested to see what your doing, shame your not doing the plenum yourself but its always good to see something different
Nick is trying to make a project for N/A Mini's like no one has seen before and instead of getting help of the Pro's he his being kicked hard as hell... Fantastic MT here... :S
Nick for you i will just say this: what doesn't kill you only makes you stronger...
If i can help in any sort of way, you know were to find me!
Best of luck!!!
