what kind of gains can you get from the 02 housing if your like buschur stage 4 already

 

Here's the best part..... the only dyno we have of O2 housings is from BR. Here is the post where he talks about the EBAY O2 housing:

If you read closely you will see that during the dyno of this part the boost went up. Lets remember that 1psi of boost is equal to about 11whp on a DSM and is probably worth more on an EVO.

Before you trick yourself into thinking the O2 housing is great maybe you should think about the fallout from that particular thread. Seems that the $80 O2 housing that BR couldn't profit from is now being sold by BR for $200.

It would have been nice to see a stock log manifold dyno with stock O2 at 23psi. Then swap in an EBAY unit and test again at 23psi. But that never happened because it doesn't make a bit of difference.
