Excellent! Please post results here, Dave!

If possible, you should try the Works one as well, since its considered the best.

Thanks!

 

Exhauuuuuusted

 

This post was rediculous as the inlet flange to the downpipe has no effect on exhaust flow when using any 02 housing that is currently popular.

I have sitting here on my desk the new Works and the Invidia 02 housings. Neither of these will work with any current downpipe being made by any popular manufacturer. I.E, myself, AMS, HKS, Greddy, Megan etc.

We do have flanges here that will work with these 02 housings. I will be testing the Works and Invidia 02 housings this week to see how they compare to the SS housing we use now.

 

Dave - care to ellaborate why they won't work, maybe with some pictures, even? I find this hard to believe/understand. Are you saying its too big? Mine seems to fit decent on the DC Sports downpipe...I will try to snap a pic tomorrow! Thanks!

 

the works one won't work with any other dp cuz they use a full size gasket but i think the invidia uses a sup thin gasket that just cones into the top of most dps.

 

I do not care to elaborate. I will test them though.

 

Cant wait to see the results.

I think you have to admit those O2 housings are huge. We just have to wait and see how they perform. Are you going to use the donut gasket on the Works O2 housing or us a flat flange with a 3 1/16" opening. My guess is yes, because the spherical flange is huge on the Works Dp, and may be hard to source.

 

I dont think he wants to elaborate because it discredits his downpipe again in the process. The works o2 is a 3 inch flange. Connected to a works downpipe that is also a 3 inch flange = 3 inch exhaust. The buscher stuff is all shrinking to fit whatever flanges they need to fit. Ya he can "throw new flanges on" but why not sell a 3 inch if your claiming 3 inch? Your setup isnt full 3inch turbo back. PERIOD.

 

Until we find out if the "true" 3" 02 and flanged 3" DP is in fact better in terms of making power, stop whining. Remember, Forced Performance so no gain at 27psi/540whp on a GT30 by switching to a 3" 02 over their 2.5 02.

 

20psiMR, is there something wrong with you? Are you able to read and see reasoning? Our exhaust system is a true full 3", if you can't see that then you have some serious issues. The outlet of any 02 housing, other than works and invidia, which both JUST became available recently, is no larger than 2.5". Our flange is meant to work with every other produced 02 housing built for the EVO and FIT CORRECTLY TO THEM. Directly after the flange it goes to 3", the 3" tubing is welded directly to this machined flanged that is made to fit to and seal to all these other 02 housings built, including the stock one. There is ABSOLUTELY NO RESTRICTION THERE AS THE FLANGE WE USE IS LARGER THAN THE STOCK AND ALL OTHER AFTERMARKET O2 HOUSING OUTLETS. Making our downpipe inlet flange 3" would do nothing but cause leaks and horrible fitment on EVERY OTHER 02 HOUSING USED, except for the Works and Indivias. That would make no sense, well it might to YOU.

On top of this NOBODY has proven yet whether the Works or Invidia 02 housings will even increase power levels. I am having a hard time believing that ONE of those two are going to do anything but kill power. We will see.

Seeing as how EVO's have been as fast as 9.90's with a 2.5" 02 housing on them and made in excess of 650 whp I'd have to say it is safe to say the 2.5" 02 housings work pretty damn good.

Until you have something intelligent to say you should keep you lame comments to yourself.

 

I think in time, once tested, the non chambered large single cavity O2 housings will disrupt the airflow so much that it will sacrafice spool and likely see no gains, if not lose power.

it would be nice to here works side to this. as they have yet to test a 400+ part and state a gain. but people see gains with other mods then including the o2. thanks to dave for taking his free time to fix that problem. thanks dave.

 

We are going to test this stuff on Trent's car tomorrow. It is a 320 whp EVO8 that has gone a best of 11.5 at 119 mph on race gas.

 

So youre saying its not 3" because the flange is not 3"...
