Hey guys, In my FD i will get full boost around 11psi with a couple boltons. Now the strange thing is that it wont reach full boost till around 3k to 3.2k while its building in the lower rpms. Say around 2.8k where it should be at full boost its at say 6 and climbing. I have a DP and a CB. I thought with the downpipe the turbos will spool sooner. Well they do in fact ill start getting boost around 2.5k but it wont get to 10 until 3k and 3.2k? I have 107k miles on my rx with the main cat never changed out. I know its pretty much clogged but will this cause a slowER boost rise? Wheres the draino?

 

Do I have bad B.O. cause nobody seems to want to help me out here or any technical NON-NEWBIE question I have?

 

you need to give it a bit of time - wait till tonight when people get home!
average cat life is about 100K

thats pretty much where it should be. the turbos do spool up faster, but were talking like a few hundred rpms, not thousands. That is about where it should be getting full boost.

 

That sounds close to mine with 85kmi. But my boost starts at about 2300 to about 6psi and full at 2900 - 3100. Does your exhaust pitch change immediately after a high load redline shift then return to normal?

 

No its just a straight nice medium to loud whurl from spool to redline.

 

same here! I'm suspecting that I have a clogged cat due to the way how my car feels slower. However, I do achieve full boost but it's just not as fast as before.
