I have searched and searched and looked under the hood and can’t for the life of me find a spot to “T” off of to get a mechanical vacuum/boost reading on a 5L Supercharged engine. I would like to run Meth injection but need to find a boost reference point to tap into sonit turns on only at a certain boost level.
There isn't anywhere to tee off, primarily because the (boosted) air is forced directly upwards out of the supercharger, through the charge cooler (where it's cooled), down through the short inlet manifolds either side of the supercharger and into the engine. If you're looking for a boost point I'm afraid the only practical answer is to drill and tap one in to either the charge cooler or the inlet manifolds.
Later versions of the charge cooler have (from memory) an M12-1.5 threaded hole on the front (seen plugged with a bolt & washer in the pic of an XKRS below) which is perfect for fitting a boost sensor to:
This chargecooler will bolt onto all variants of the 5.0 v8 SC engine - I've fitted one I found brand new online for a great price to my 2010 to allow me to run a boost sensor off it.

Thanks for any help.

snow performance and other meth companies seem to indicate pretty good success using reference points from the MAF sensor. i know our car has (2) MAF sensors but they claim either will do
Mechanical Boost Reference Point on 5L engine?
