    Qestion about rrfpr and about boost guage

    These may be a dumb questions but I would like to get some opinions.

    1. boost guage
    I'm going to be installing my digital boost guage in the next few days and I know the general opinion is that the ic blockoff is the place to put it. The thing is, my ic blockoff is siliconed in real nice and air tight so I didnt want to have to mess with it and pull it off to drill/tap it. What I was thinking was to drill/tap the bov blockoff plate in my ic tubing. Seems like it would be a good place to me because it is right after the sc so it should be an accurate spot to get a reading. Opinions?

    2. rrfpr
    Does the rrfpr need to read vacuum, or just boost. I ask because I was thinking of hooking the rrfpr in that same spot. It would not see vacuum when off throttle because the butterfly is closed. Would that be ok?

    I think I know the answers to these questions, but I love to get second opinions

    The IC blockoff is the best place for the most accurate reading. It is also the best place to pu tthe vacuum line for the RRPFR...

    I SUGGEST you simply pull the IC BO off, tap it for both, and put it back...

    shop vac

    just get someone to hold the shop vac while u drill and tap the hole.

    or pull the b/o out and redo the silicone.
    the b/o is the best place for the guage and the rrfpr

    Why not just put a "T" barbed fitting with one end going to the boost gauge and the other going to the RRFPR?

    Its better to run 2 separate sources, than split one source...

    I would not take a chance on it running lean with the split source.
