JohnFlovin 11-08-2011, 02:23 PM Howdy all, I'm getting ready to install a boost gauge and wanted some advise. Should I install a "boost only" gauge on the positve side of the turbo? OR Should I install a vacuum/boost gauge into the manifold? John Flovin djwhiplash2001 11-08-2011, 03:38 PM Definitely want it into the manifold - that's the best way to spot for boost problems when they arise. Plus, not sure tubing would like the temps from a turbo's hot side. Vacuum is very important to monitor as well. ever93 11-08-2011, 03:50 PM Ima get one too. But what's the difference on those connections? Ever JohnFlovin 11-08-2011, 04:40 PM The postive side of the turbo will read plus or pressure all the time, the maniflod will range from vacuum to pressure/boast JohnFlovin 11-08-2011, 04:41 PM There is a cool spot right after the intercooler that you could tap into... djwhiplash2001 11-08-2011, 06:04 PM Yeah but that boost isn't always what the motor sees. Definitely use the manifold for this application. Whether you want vac or not is up to you, but I would highly advise it. DonJuan1Jr 11-08-2011, 06:16 PM Holy ****....smh punkpie 11-08-2011, 10:26 PM ^ LOL It's "boost" not "boast." Unless you are trying to gauge how much your car is bragging. JohnFlovin 11-09-2011, 09:13 AM Thanks as it was a long day, however, with Iebach springs, Carbon fiber cool air intake, Magnaflow cat back exhaust, tinted windows, all on a 2012 R-line, it could be "boast"... JohnFlovin 11-09-2011, 09:15 AM Howdy All, Thanks for all the feedback, I looked over some vidoes on Youtube of different boost gauges placement and operation, along with your input, I've decided to go with the vacuum/boost gauge. John JohnFlovin 11-22-2011, 09:25 AM Howdy All, Well I just received the boost gauge in the mail. I decided on a 30vac/20psi gauge. Also to make the installation a bit easier I found an adapter kit that mounts inline with the PCV valve, and guess what all the lines/hose for the adapter and gauge are the same size. I hope to have it mounted and hooked up this weekend. Have a great Thanksgiving... John djwhiplash2001 11-22-2011, 09:47 AM That adapter makes install pretty easy... let us know when it's installed. I'm not sure about the TSI, but on my FSI I've seen the boost run as high as 25PSI after a chip. JohnFlovin 11-22-2011, 03:24 PM 20 sure be plenty as mine will top out about 12 psi JohnFlovin 11-28-2011, 02:43 PM Howdy All, Installed the boost gauge over the weekend. It looks and it works great. I mounted it on the dash between the sterring wheel and light switch. :) John | |
