not directly a subaru question, but more of a general info... I notice when looking at analog boost gauges that run off a line and not an electric sensor, they come in a few different ranges. Before wide use of digital monitoring, and digital gauges, did that mean to get accurate boost readings across a wide boost spectrum meant having more than one boost guage installed? aw, nobody knows? I can't find anything online yet either.
automerge sucks... Kanchou posted 2 posts 24hours apart and they were merged.... please fix this piece of crap -- Brian
i dont really udnerstand the question, why would you need mroe than one gauge an electric one would tkae care of ALL ranges
now honestly, i am not sure what you are asking, but from what it seems to me, you are wondering why not the same size vacuum hoses are used for each boost gauge. that is b/c the same pressure is being read, whether the size of the hose is different or not. If that isnt what you were asking, please clarify it for me. brett(after a few pitchers)
say in the 80s your ran 20lbs or more of boost. Every aftermarket or racing boost guage application I've seen before(granted limited to less than a dozen) only read accurately in a very narrow range, and above or below it they flickered wildly. So before there were digital sensors widely used on this stuff I was wondering just how people monitored the entire range of boost accurately. Did they just not care about boost pressure outside of their power ranges? Or did they have more than one guage(because they come in so many ranges)?
Intersting. I would be suprised that soo many gauges wouldn't read accurately over a wide pressure range. Do boot gauges work off of static pressure, the same principal as an altimeter?
Hmm, I wonder if people just didn't care about boost other than their setting... If it reads higher than the boost should be, its too much. If its lower than the boost setting, then its too low - turn it up! Thats my guess, but its just a guess...
hmm, maybe I should ask a volvo, mack, or international mechanic or something? I work with a few in my line of work...
