I recently purchased a Ractronix dual intank pump and it came with a Hobbs switch, it appears to be a 1/8 NPT male. Where do I install this and do I need any adapters to screw it into the manifold?

If you have the EGR block off plates installed, you could drill and tap a hole in the plate off of the car. That way you wouldn't get metal shavings in your intake manifold.

You could also buy the boost switch sold on ebay and run it off a vacuum line. Thats the one I bought.

 

Thats a GREAT idea! Which one of the plates do I drill?

There are two holes the EGR plate covers. I think it is the lower hole that goes to into the intake manifold. I can't remember for sure.

 

hmm, good idea, but the plate isnt too thick....is that were you have yours mounted? Waht did u use to tap the plate with?

 

did u guys tap the top or bottom...lol
