Trick Flow intake - need help with vacuum hoses/routing

[shackf16]

I am getting close to first start on the new engine, and hopefully not too far from getting back on the road again. I had a local engine builder rebuild my short block and install the Trick Flow top end kit for me. However, I have to install the upper intake manifold and the necessary vacuum hoses, and I'm at a bit of a loss. My car is EFI without any emissions equipment. I have a hydroboost setup, so no vacuum booster, and a manual T5 transmission.

The bottom of the upper intake has 4 ports: 2 facing forward and 2 facing the rear - one of them is larger than the other three. There is a large port on the driver's side outside edge near the firewall.

The lower intake has a medium sized port at the back by the firewall. Other things that I think need a vacuum are the fuel pressure regulator and the MAP sensor.

Included with the intake were three brass connections, 3 rubber plugs, a larger block off plug, a little spacer, and a silver tube wrap thing.

Any help would be greatly appreciated with specifics on what needs to go where.

Thanks!

The port in the back/side in picture #3 is for a vacuum booster. Since you don't need it, you can plug it. The larger port under facing back is for the PVC valve which you show in picture #4. The other ports you can use for your FPR and Map. Any extras you can plug.

I think what you are call a MAP sensor is actually an BPS,(BAP) barometric pressure sensor. Do not connect a vacuum hose to it, it should remain open to atmospheric pressure.

For clarification:
With Ford EEC-IV systems the speed density version uses a MAP (manifold absolute pressure) sensor which gets connected to a vacuum port to read manifold pressure. The mass airflow version uses a BAP (barometric air pressure) sensor which does not connect to the manifold and reads barometric pressure. The devices are the same but read and report different conditions to the ECU depending on the system...SD looks at pressure inside the intake, MAF looks it atmospheric pressure outside.

Rich and Jeff are both correct. BAP measure atmospheric pressure not vacuum. Sorry bout that, I should have looked closer at the picture for that.

Thanks guys - this was the confirmation that I needed. I didn't remember a vacuum hose going to the BAP sensor, but it's been a while since the tear down and that tube on the side looked like it was asking for one... ;-)

Hopefully I'll get this hooked up today and keep moving closer to the new "first start".

Cheers,
