How much boost???

[87soup]

Has anyone else ran into his under boost problem???

Im using 91octane now and it still stops spooling at 8lbs....
All my pipes are tight and no vacuum leaks...

The only things different about my set up is the BOV, and my O2 sensor...
Also the Y-pipe i have comes with two holes in it for wideband and O2, well i dont have wideband so there is an optional bolt to plug it... That bolt fell out and now i have a hole there the size of a O2 sensor:nono:!

:1zhelp:

3" Y-pipe, 3" Down pipe, 2.5 cat back, Cheap muffler...

I'm still running the N/A cat back!

That is probably the source of your problem, regardless of the ypipe and downpipe.

The 2.5in catback.

Remove it briefly for a test. See how much boost you can make without the restriction of the catback.

i agree. try that and i would buy a boost controller if your planning on cranking up the boost. do you have an aftermarket boost guage?

what is this contraption known as a catback you speak of?? All I know of is teh open DP lolz.

Agreed with what OneJoeZee said. Although I doubt thats the full extent of the problem.. Hmm.

Joe made a really dumb MSPaint picture a year or two ago that explains this really well.

Dumb but effective.

Best diagram ever! You don't need to T the compressor ports together though, they are both measuring the same vacuum. I ran one of them into the boost controller and capped the other.

 

[OneJoeZee]

Yeah that would work too.

Same difference.

BEST Damn diagram ive seen!!!
