Question about tapping boost gauge line into CTSC intake

[gobble]

The CTSC intake has a 1/8 NPT tapped hole to screw in the adapter for the boost gauge line. I started screwing the 1/8 NPT male adapter into the hole, with liquid thread sealer on the adapter, and it gets real tight and turns real hard about 1/4" into the hole. I'm at about 10 lb/ft right now and don't want to go any tighter for fear of stripping an aluminum intake with a steel adapter.

I did notice that there are numerous other places on the intake where Comptech has screwed in similar fittings. All are screwed in very deep. I'm confident that I have the correct thread size in both the hole and the adapter.

Should I keep going and tighten the thing all the way down or stop at 10 lb/ft?

gobble,

Did you get any guidance on your question? Also, where did you decide to mount your boost guage and what boost guage did you get and from whom?

Still waiting to receive my CTSC and will soon be plotting my installation.

Thanks!
John

I spoke with Shad today and he said to turn the fitting until its tight with a wrench. Don't overtighten it.

I made a plate to replace the ash tray and mounted the Z series Autometer boost gauge and the Z series Autometer electrical fuel pressure gauge. If you look for my old thread, you will see a picture that I took of the finished product.

Do you by any chance might have pics of this location?

If it is a tapered pipe thread the threads form an interference fit as the tappers engage. Do not over tighten you will strip the threads out of the Aluminum manifold.

I just got my Defi stuff today. All is going into my oem navi pod. 2 defi link displays, BF boost guage and remote V1 will all go in it.... I hope :biggrin:

Did you have a pic of the location you used for the boost hook up. I'll look at the CT web site too.
