what vacuum level does your stock boost gauge show at idle

rocketwrx · 02-04-2006, 10:22 PM

Mine seems to be at 0.06 mpa at idle when warm with everything off, slightly less if I have the lights and A/C on so forth. Sound about right?

That sounds right on. My car likes to sit at 500mm/Hg at idle, which is approximately 0.066 Bar.

Good, thanks. I just put the gauge on yesterday and everything seems spot on. I also put on the SPT exhaust, which sounds fantastic. I love that boxer sound.

Ditto on the Boxer sound! How does the SPT setup sound compared to stock? Like, way louder or more subtle?

rocketwrx · 02-05-2006, 02:02 PM

It is considerably louder than stock. Has a real nice sound, deep and not ricey. I haven't gotten it out on the highway yet, hopefully it doesn't drone.

It was kind of a pita to put on because I was really wedged under the car trying to get at the front part of the mid-pipe. I had the back jacked up as high as my floor jack will go and onto jack stands (although I had to let it down a bit to get it on jackstands, unfortunately- I needed about 1/4 inch more to get to the next notch).

That meant that the front of the midpipe was hardly lifted. I was jammed under the thing, couldn't slide in from the side- had to slide down from the back to the front on the creeper until I was basically wedged under the floorpan. Other than access, however, it was a pretty easy job. Getting the old exhaust out of the hangers can be a struggle.

Would have been easier if I had another set of jack stands to get all four wheels off the ground.

do you mean -.o6 mpa? shouldnt it be in vaccum at idle? i have a boost gauge that reads in psi and at idle its at like -9.XX psi

rocketwrx · 02-06-2006, 09:45 AM

Yes, I mean its -, as in vacuum.

Got to log some mixed driving including highway time with the SPT cat-back today on the way to work. Its pretty loud, has a deep sound. Not ricey. Its maybe a little louder than I'd prefer at idle or low RPM's. Sounds good when accelerating. It does seem to drone a little on the highway in the wagon, but its not real bad.
