Dakota Gauges - flywheel induction and turbo boost

[FDo5g]

Good afternoon!

I’m in the process of installing my Dakota Digital gauges in my BJ 42. At the moment I have decided to go with a flywheel induction sensor for the tachometer, but don’t have a port in the Bell housing in which to install it. For those of you who have installed these aftermarket, did you drill the hole yourself? Or did you take it to a machinist?

As for the boost gauge, it’s 1/8 npt threaded male probe - for those of you who installed such things in your rigs, where did you put them? The crossover tube? The silicone elbows?

Thank you so much in advance for your help!

Specs: 1978 BJ40 w/ approx 1983 3B engine, 24 v, aftermarket turbo kit from diesel42.

I would put the boost sensor in the intake manifold but you can really put it anywhere except the silicone elbows i don't know how you could attach it there. (make sure you take things apart before drill and clean out all chips) If your set on the flywheel sensor you'll have to drill a hole in your engine/bell-housing to get to it. If it was me i would use the w terminal on the alternator ( you might have to open the alternator and add it but it's easy. )

i drilled and tapped a hole in my bellhousing for the sensor, not too hard just be careful you have enough meat for tapping

The Dakota digital boost sensor is meaty enough (1/8 npt) that it could be screwed into a slightly undersized hole in the silicon for the crossover tube and likely be fine. The having been acknowledged, I created a "T" fitting in the waste gate circuit and will be using that for the boost gauge. Can the w-terminal mod be performed without removing the alternator?

I am so grateful for your response!!! any tips on how to go about this drilling and tapping? hand drill ok? placement on the bell housing?

its probably possible to do it in place but will by way easier to remove the alternator. if your inter-cooled then you'll have a more accurate reading at the manifold then the compressor housing.
