some info for people wanting to do a cut out

inspected · 2008-09-06 09:26:46

Just some basic info. with a cut out when it is closed you will always have a slight exhaust leak. Next if you are boosted when i ran 10 psi with the cut out open my maf would max out. i know have a maf clamp. so be ware the power gains are great but you may max your maf out.. just for some basic info...

so the maf basically maxes out based on hp not how much psi?

it maxes out from airflow so if this cutout is open then there is like no back pressure and the airflow increases.

SWEET! more of a reason to upgrade the maf, THANKS GUYS!

maxes out the maf at 10psi? how does more air flow thru the intake side? should still be 10psi right? also what kind of exhaust are you useing otherwise? im wondering how much of a diff it is over 3" cat back.. also where is your cut out placed? can you take some pics please? maybe a vid from outside the car so i can hear what it sounds like? thanks man, RJ

Cutouts are gay just run open downpipe all the time and you are set lol and also you save some weight by no having an exhaust

RJCornine · 2008-10-09 15:41:52

yea ever hurd of noise violations? yea at 300$ a pop you wont run around without an exhaust for long here.

for those that max out, z1auto.com has the 3" 350Z maf housing for $110 shipped. You need to have an 04+ MAF as the 02-03 plug is different.

cfm =/= psi.

so still looking for placement? i was thinking about putting one about 1/3 down the mid pipe before the 2nd o2? but i need to check clearance to see if there will be any issues? anyone who can take pics of their cutout installed and post that would be super helpful. thanks again..

V-band that shit.

RJCornine · 2008-10-14 12:20:14

i thought someone said you wanted it as close to the downpipe as possible? anyone else got more photos? Mine is on the way just trying to sourch placement before i roll to the muffler shop

*edit: Thanks Specd_out for posting pics, just hoping to see more.

does not matter It wont really fit anywhere else. the loss of power from having it a few feet back wouldnt even be noticeable. I am going to be doing 3" from the turbo to the cut out and then leave my greddy stock.

i have a v-band on the turbo... i wonder how open turbo outlet would sound...

specd_out · 2008-10-14 19:28:47

downside to that is all the exhaust gases are dump into your engine bay along with all the heat. not to metion it would be a direct flow of 1300 degree gases right into your altenator

You don't want to do that...It would be EXTREMELY loud, and like previously mentioned you would be dumping some HOT exhaust gas right in your engine bay. A fire waiting to happen I'm sure...
