I was thinking the same thing, do you think you could machine some trumpets?

You could do that but it wouldn't gain that much in terms of flow. It's well proven that a tube with an 1/8" + radius on the edge will flow 98% or so as well as a huge radius (trumpet).

This is good for OP because it is very easy to do and he has plenty of material to work with.

Looking forward to updates.

Nice work!

The square corner on the manifold's entry to each cylinder is going block a lot of airflow. A radius on that edge will make a huge improvement on airflow and does not have to be very big, anything 1/8" radius or larger will basically give you maximum flow.

That's what this picture is about:


I will be putting a 1/2" radius on all the holes. That's why I made the plate so thick, to allow for the radius.

[LJ851]

^ Well done. I thought that part was a little out of character for you.

[AndrewBird]

Fixed!

The air will be pleased to enter your engine now. Router?

[AndrewBird]

Yup. Router with a 1/2" round-over bit with a ball bearing guide.

Got the fuel rail modified.


New mounting tab.






In place.


Also bent the fuel line tube so everything clears now.
