o2 dump vs. o2 housing
What one is better? Benefits of both.
I'm looking at doing bolt-ons on my evo 8 and can't find any solid info. (tried searching)
Looking for most efficient and most power making bolt-ons. Any links or info will be apreciated.
Oh and things I decided on already are:
Ets fmic
Bigger pump/inj (e85)
Porting exhaust manifold.
Car has gsc s2 cams and tsudo exhaust.
Thanks for all the help

I am running an Evo IX turbo with the FP antisurge cover, and a ported hotside. I have the JMF O2 Dump, and I have zero control over my boost. The least amount of boost I can run is 26psi. I have removed my boost contoller, I went back to the stock IX WGA. I adjusted the preload way out, and now the turbo is lazy, and still runs 26psi no matter what. I can only go up in boost.
For most people this is not a huge issue however for me I like to road race my car, and I need to get the boost down to about 20-21psi, to get the HP and TQ.
For a stock turbo I would recomend you stay with a standard O2 Housing. The dumps are cool as hell but you will have zero control of your boost.

^ how is the post turbo exhaust not letting you controll boost?
I have grimmspeed ewg (Vta) on my rsti, so I'm familiar with noise.
Anyone has hp number gained with o2 hosing vs stock and vs dump.?

They're both great choices imo,i've tuned cars with both and i preffer the dump for max power and the noise it's not really as bad as you might think,be aware if you buy the one piece housing and downpipe that it will be in the way for basically anything you work on under the engine since you can't remove the downpipe anymore.

I might try to port my even more and see if that helps, but for now I am either going to make my own o2 housing or switch to a titek.

I like the discussion here.
I have been battling creep issues with a ported Megan 02 housing with a ported BBK-Full on a 2.3l. I believe that there could be the possiblity of not enough restriction on the 02 side which could actually some weird turbulence/backflow or whatever it maybe. I wouldn't know unless some engineer type looked at it in CFD or something like that. I had to work around the creep by running more boost...weird how that works.
I know that some DSM owners ran into creep issues with 3" exhaust setups.

My muse o2 dump runs low boost on my 71 hta. Its designed well
Megan racing o2 was horrible for boost control. Crept to 23+ psi even ported.
Spool no, depending how bad your current set up is holding you back it will clean up some power. I didn't gain much power just boost control.
