MAP Sensor Mount

Changing manifolds from the stock LS3 to the Holley Dual Quad Manifold has left me with out a MAP Sensor mount.
The Holley Manifold has a 3/8" NPT port on the back of the manifold as a vacuum port.
Usually this would be used for a Brake Booster or Vacuum Tank, but i will use this port for the MAP Sensor.

The boss on the back of the manifold is shaped like a shield, the 3/8" NPT hole is not central to the boss.







My son Tom is studying year 12 systems engineering, he's in to all the latest tech gear, 2 years ago, he invested in a "Kickstarter" project by a company called Formlabs who were developing a high resolution SLA 3D printer.
For his backing, he was entitled to a 3D printer when they started producing, which we received in March 2014.

So, for the MAP Sensor mount, I designed a part to fit the boss which would be held in place by a 3/8" NPT plug with a 12mm hole bored through it for the MAP sensor to locate in.
The MAP sensor is then bolted to the mount using a Rivnut held in place on the reverse side of the mount.





Printed part using clear resin.

Finished part with a Rivnut insert from the rear with MAP mounting bolt.

Dual Throttle Linkage

Made up a Dual Quad Throttle Linkage to connect the the two Throttle Bodies together.

The linkage is made up of  two 1/4" Unbrako Shoulder Bolts that fit through the linkage from the inside then through two 1/4" Rose Joints for low friction and secured in place with Nyloc nuts.

The Rose Joints have threaded shafts, 1 Right hand, the other with Left hand thread connected with an aluminium shaft and lock nuts.

The opposing threads make it easy to adjust the linkage to the correct length by just turning the shaft.
