Epm o2 dump

 

OK i still dont know if it is better then a reg o2 housing?

 

O2 dump will be better than a recirculated O2....

turbos don't like back pressure...and jamming those wastegate gases back into the exhaust causes back pressure....

less back pressure = quicker spool up

 

thanks alot man i under stand now. the extra whole i would take it that is for the wideband sender or the stock o2 sen?

 

That's correct.

 

epm o2 dump ftw. pita to install, but deff worth it

 

extra hole? are you talkin about the QTP Dump?

the bung or "hole" that's in the O2 dump is for your front O2 sensor....

widebands are recommended to be at least 36 inches from the turbo...

although you can make the sensor for the wideband closer to the turbo but that will shorten the life of the sensor

 

on the qtp there should only be one bung and that bung is to replace your original o2 sensor back. your wideband if you want one should be installed on the downpipe as far away to the turbo as possible..i installed mine right before the test pipe. Also qtp ftw!

 

u are the man thank you also with the open would that mess with you emissions and ecu?

 

it won't mess with emissions or your ecu...

exhaust gases will only come out of it when your boosting

 

Listen to this guy he has QTP O2 dump as well as AEM wide band installed recently, he also knows someone with a EPM O2 dump.

 

thanks now i just need a 10.5 hotside any one have one 4 sale

 

Just keep in mind an o2 dump is an illegal item in PA. It's like running an open header and will not pass state safety inspection. If you got a "connection" thats cool, but a by-the-book guy will not pass it and take a chance to loose his license.

 

are there any other drawbacks to a divorced style 02 housing?
