Boost Gage Location

[stick]

I have a friend that just purchased a new 2001 CTD. He wants to install gages (boost, pyro, and transmission), but I don't know where the 24v are getting their boost from on the engin(dumb old 12 valver) I did a search, but got tired of looking! Any help will be appreciated.

Three places.



Use a "T" on the elbow at the turbo.

Tap the intake horn.

There is a fitting on the side of the block that can be removed and the reading taken from there.



I currently have my intake horn tapped, but just got the Banks High Ram, and will be moving mine to the side of the block in preperation of my AirBullDog Hood Install.

I know the pics kinda suck but I am pressed for time, I'll get bigger and clearer pics up later tonight. I had to do it like that so it would upload.



So soon as I get back later tonight I'll work on editing the pics.

Ditto what Kat said. I used the fitting on the side of the block. It was easy to do. Just unscrew the existing fitting/plug and screw in a new one. I needed a 1/8 npt for my sensor and picked up a 3/4 to 1/8 npt for about $1. 50. If you can't find one that size you will not have a problem going from 3/4 to 1/2 or 3/8 then 1/8, but the fewer bushings you use the better. The plug on the block is just behind and to the right of the fuel filter canister on the drivers side and is fairly easy to get too. There is another fitting that looks the same farther to the right and harder to get to, but if you unscrew it coolant will come gushing out.

This was covered before, but to remind anyone who is going to use the fitting on the side of the block, you MIGHT get gauge buzzing and pulsing since that source is so close to the cylinder intake. I have seen it happen in about every install in that location when using mechanical gauges. The intake horn is easier to get to and simple to drill and tap and there is no chance for gauge problems. Just take the 4 bolts holding it in place out and then drill and tap it with an 1/8 or 1/4" tap (depending on your fitting size). Bolt it back in and your done.

If you are going to use the plug in the block, make sure you get a reducer that has a small "nut" on it becasue the block tapers upward and wont let you tighten a 3/4"x1/4" bushing.

Stick,

Take a look at my How-to for EGT/Boost gauge install, you can get to it from the St Louis TDR members site. Just go to the HOW-TO section. I don't get any buzzing or pulsing from my Westach gauge.



Hope this helps.

KatDiesel~I noticed in the pic that the boost was put in the top of the intake horn. I have seen people put it on the side firewall side. Would think putting on side easier to route line without crimping it. Any thought?

No crimps ever, and no problems ever. The top was just easier to access, and I didn't want it "hanging" off the side. I was pondering doing it on the underside... . if I can fit it in there, for my AirBullDog Hood installation, but in the mean time I have a Banks High Ram to take place of the stocker.
