    boost guages

    For those who have boost guages please post your pro's+con's on these.
    I have used the search engine and all i can say is that i am more confused now then before.

    this was a long time ago but this was one of the best i ran across by shibbster

    Sharing My Boost Guage Research w/ you all
    I'm very very particular, and takes me several months to buy something and commit to it, haha. Finally bought my catch can from JAZ today over the phone. So i moved onto looking for a boost guage now and spent this week making many phone calls and online research. Here's my findings:

    1. Analog vs Digital ~~ GO ANALOG! digital is way to sensitive for our application and the decimal numbers will be flcikering like crazy and drive you nuts trying to see what it says. it's blingy. 2 auto companies told me, if you have a Honda and you are some teenager off the street, then you'll need a digi guage to blend in. the pros and high performance boats and race cars will only use analog

    2. PSI intervals ~~ since we will typically be running in the 7-9 PSI range, go with a 0-15 PSI guage... NOTHING more. otherwise you wont be using like 90% of the guage and your eye will not be seeing a very accurate boost reading because of all the numbers and lines and dashes.

    3. Mechanical vs Electrical ~~ for starts, electric is far more expensive? my question was why? is it more accurate, more desireable? NO. costs more because it's more parts involved, more product. one will not be more accurate over the other, as a matter of fact 2 different companies over the phone recommneded their cheaper mechanical analog guages over anything because of precision, direct reading off source of pressure, and price.

    4. Waterproofness? ~~ are they submersible? NO... can they take some mild splashing throughout the day, yes... should not be a problem at all. if you wanted to go an extra mile and seal it up somehow, go right ahead, but then you risk that the guage will fog bc it has no air to vent it. besides, if you go with their recommendation of analog mechanical guages, you can afford to jsut get a new guage every year worst comes to worst for 35-55 bucks whereas electric and/or digital are 180 - 225

    5. What brands? ~~ autometer is huge in the business, been around forever, make an awesome product. only other recommendation is Nordskog. They are huge in the MARINE guage business and very reputable. come with powdercoated housing and brass hardware for marine environment

    **hope this helps some of you in the market for a boost guage and in the future for newb

    i know the dynotune is the one most recommend but certanly not water proof also what do you do when velcroing on your lid you close the lid on the wire?

    i will not see any boost until i reach 6000 rpms?
    liquid filled is always the way to go as it wont bounce around?
    the round guage mechanical you need to have access for the back bolt to ajust or reset it? how is this possibble with the mounting in the steering pad?
    what about the ones that are digital (electronic) how diff to wire them?
    I liked danny's and mxl16 set up but the mirror one was good also

    thank you

    That is some real bad info. The digital gauge that i use, and most of the people here use do not flicker around. They hold solid and and extremely accurate.

    Analog on the other hand will have a needle vibrating so badly under boost you can barely read it . It will be vibrating 3 psi either way.

    Yep, there is a rubber seal that is forgiving and the wire just pushes down out of the way.

    This is very true. The only good thing an analog guage will show you is if you have a leak and are making no boost. No accurate numbers.

    just do a search and put boost guages with an s and see his posts.

    here are a few more?

    better reading liquid filled?
    mechanical you plug to block off nipple and you are done?

    you tube is good source as i have seen boost guages before but not familliar with their aplications properly

    boost will only show above 6000 rpms the ones on you tube work all the time?

    if i stay at constant speed if only above 6000 rpms guage will always show boost let say 10 psi?

    what about wiring this one on a scale from 1 to 10?
