What do I need to do to hook up my boost guage? And where can I run my lines through the firewall? I tried searching but I must suck at it, cuz nothing came up, and I thought I rememebr seeing something about doing this.
forgot the guys name on here,but he sells the fitting to get vac for the boost gauge.
the best place to get vac is from the brake booster line. he sell's fitting that goes on the intake and has a nipple coming off for the vac line. hyrude or something like that was his name on here. best place to go on the firewall would be on the pass side. you will see a black rubber cover with the antenna wire. you could poke a hole in there and run the vac line
The general recomendation is nope. Those are dedicated lines and need to only go where they go. However I've never seen it where someone used one of those lines and had a problem. I'm sure someone will jump on this post and correct me.
AFA getting through the firewall there is a spot just above where the throttle cable comes through you can use. Look on the inside for a pre-punched hole in the matting that needs to be removed. I think I then drilled a hole and installed a grommet.
you can run it on a vac line,but there are some vac lines with a one way valve on there. using one of those. will either A. not give you a reading or B. get a wrong reading .
using a vac line with out a one way in it can also give you a wrong reading.
seeing that where the hose comes off the booster is the main one. making it your best bet and making sure you get the right reading.
RPM SELLS A BRAIDED HOSE TO REPLACE THAT CHEAP RUBBER CRAP AND IT GIVES U A PLACE TO HOOK UP YOUR GUAGE .... WWW.RACEPROVENMOTORS.COM... WELL WORTH THE PRICE.... IN MY OWN OPINION....
