Just when you thought this was dead....
Sorry to bump this but I received a couple of questions the other day for pictures that would better indicate how things would/could mount up with the Peninsular intake w/o the spacer.
When 635’s motor was built, the spacer idea was still a couple of years off. Jamie Avant instead opted to drill and tap the lower intake to accept OEM Boost and IAT sensors. Along the way, the sensors for IAT & Boost were added along with a two stage WMI, Propane and Nitrous Oxide. In the end, the lower intake had four 1/8” NPT and one 3/8” NPT holes tapped. The Cummins elbow already came with one 1/8” NPT port but a second was added that is 8mm x 1.0pitch. The Peninsular hat received a 1/8” NPT tap as well. The pictures below have the holes filled with something to highlight were the drilling took place. The front side held the IAT and ECM's Boost sensor. The Boost sensor was held in place by a small bracket attached at the intake, like an SSD PMD "Cooler" only functional.
Front side with two taps. The boost line is a 1/8" NPT to 1/4" barb.
Back Side with three taps
Peninsular w/ one tap
Cummins Elbow with factory tap on top and additional tap plugged with bolt
Here's a progression on the set up I'll be using which is with the lower intake's taps plugged up and using the my spacer for the sensors. I'm using these parts bacause unlike mine currently on the truck, these have all been extrude honed internally to include the OEM upper intake (not pictured). So, I've got choices.
Here's the parts with my old upper set up assembled and 635's parts.
"Plugged" Lower intake w/ spacer
Peninsular upper in place
Boost and IAT ensors in place on the spacer
Cummins elbow attached (my old unit shown now for simplicity...hard to hold the pieces in place and take pics)
Steel mandrel bent piece completes the set up.
Hope this helps as I'm pretty smoked so I hope this all makes sense.
