The other piece that’s missing that I don’t have yet is the little velocity stack piece but I’ll be making that soon maybe this week.
So I haven’t done any sort of calculations yet on what the volume of the intake manifold should be . I started reading into the volume and length of runners and just ended up find a lot of different ways to go. I’m just trying to make the best intake I can while I’m at it , but there is so much to take into account like displacement , cam duration, desired rpm. I mean for it to be legit I’m sure it would need to be flow tested and the rest of the setup to match .
I had a couple ideas for how to make a manifold that’s even more “professional” looking which would be
1- buy a pre made one and adapt it to the car like pictured below
2- make a set of runners like The RS3/TTRS port injection runners . But flip the bolt pattern on the manifold side, so I could run the TTRS intake upside down . I thought it would be cool but the problem I see is this would put the inlet in the top and I’m not going to buy an expensive used one to find out it doesn’t work. I could run it in the standard configuration though. I think it’s got provisions for flaps ,position sensors and other shit I don’t ever want to see again though .so that’s how I end up trying to make it .
These could be really cool but you’d have to modify it for 5
