Default Boost gauge??

Hi all,

I installed a Roush M90 supercharger on my 2010 GT. I'm trying to install a boost gauge, but it will only read vacuum. I'm working to get boost reading, but cannot figure out where to connect. I'm tapped right now to the brake booster T. But the gauge doesn't show boost, only vacuum. What am I doing wrong?

Thanks!

I took it off the line that has the brass fitting into the roush manifold. You can see pics over at fnsweet.com

Have you driven it yet?

There is no brass fitting to the manifold. I wonder if roush changed for 2010?

I have only driven a little. It hauls azz!!

Just thought I'd let you know...yes.







Yes, I am jealous of you and your M90.

That is all

I bet! Especially with your cams, you're basically driving my dream set up without going forged!

I think I am about maximum without forging. At least for my comfort level. It runs really hard! Love the sound it makes.

I'm sure it rips, especially with 373s!
