So I'm sure by now everybody has had their issues with our stock boost gauges on our wonderful LSJ motors. Of course when the power is off the gauge shows vacuum, that gets old after awhile. I recently upgraded to a 3" pulley and other goodies and my boost gauge read 14 psi (the stock one) I had a hunch that this was off but I didn't know by how much.

I put an after market boost gauge by Auto-Meter and wow what a difference. The after market boost gauge reads 16 psi at 7000rpms where my stock reads 14 psi at 7000rpms.

I know this has been discussed before and will be again but I wanted to throw in my thumbs up for a vacuum fed boost gauge and post some pictures of my mounting and gauge choice.






Oh yea, and the random picture of my mounted NOS energy drink courtesy of SummitRacing. Fortunately I'm one of the people who live in driving distance of that wonderful place!

umm u do kno why the stock gauge is in vacuum when the car is off right (just in case--its cuz its electronic) and that energy drink is fukin cool hahahahaha

Yea, that's why I replaced the gauge and that's why it's reading inaccurate it's all estimated, therefore the reason I replaced it with a mechanical gauge.

Anyone interested in a used Autometer Phantom boost gauge?? I also have an EGT and Oil pressure, same type.

just saying, i never had a problem with my stock gauge... temperature could have had a say in the difference in boost pressure. when its cold out.. my stock guage will creep up on 18psi wit a 3" pulley and tune

I like the CF Gauge but that mounting is FTL. That would annoy the crap outta me. Glad you like it though. I have only once seen my gauge reach the factory spec of 12psi and that was at WOT in third gear at 5k rpm after my airbox mod, so I agree that the factory one is less than accurate.

Make me an offer. I will try to get pics tomorrow, gotta see if my buddy wants to buy the EGT. The others will be up for sale right now though.

Continuing with the thread jacking... Is the boost guage the vacuum/boost or just boost. And if it is the vaccum/boost is it the 30psi or 20psi model?

Boost gauge is vaccum/boost, 20 PSI. That and the oil pressure retail for ~50 bucks each, but I have just the gauges, not the sender/tubing. Make me an offer!

I replaced mine as well...mechanical is a lot more accurate and a lot more responsive than the stock one. Two thumbs up.
