Hey thanks! Ceasar's car is finished and the jig is ready to go. The dump will not work with stock lower intercooler pipe, but since most people who are going this route are trying to extract all they can out of a stock-style turbo the odds are pretty good that the factory lower has already been replaced.

 

^so do we ship the o2 housing to you or do you have some ready to be made ? i dont have an o2 housing yet.

 

So, is this going anywhere? You'd think with 9 pages, we'd be somehwere by now :P

I'm hoping they're going to be made from scratch. It'll look and work nicer. Maybe be a little more expensive, but also save alot of shipping hassle.

 

Drifto- "Welder/Fabricator/Owner of MPFab" He said the jig is ready. Good news. Possibly more info? Thanks.

 

ICS Performance in Connecticut makes these as well. Not sure if they still do. They test fitted a red Evo9 with it and they saw great results. i don't have the specifics of the results but Al (dynoflash) does. They tuned my car the same night that evo9 was tuned. Anyone interested can call George (cool guy) at ICS....203-653-2394.

 

Making a new housing would look better but I doubt it would perform any better. Plus most people already have the e-bay O2 housing because it's a great bang for the buck item. I bet most people would rather have their exhisting housing modified than to have to buy another unit. Plus, the e-bay item is so inexpensive it would be hard to justify spending a good bit more money just to have something that was prettier. It hardly visible once on the car.

 

^Id rather buy a whole new housing and have it look better...something like how the dsm ones that are made...?

 

Im down for either option. All we need is the pricing.

 

I'm good with just having the ebay housing modified. You really can't see it that well anyways. And most people don't even know what they are looking at.

 

same here

 

werd! For sho!

 

I have a notion:

I think the spike we have with our stock turbos is necessary for peak whp/trq numbers and helps in acceleration. When using an o2 dump we can expect to control boost more precisely....i.e. eliminate the spike. Our cars can hadle a 24-25psi spike (tuned). The o2 dump isnt gonna help us keep higher boost at redline (or is it?). It simply reduces the chances of overboosting, a condition plaguing our small quick-boosting turbos.

So i guess this is how it will help. Setting boost to 22lbs, will no longer net a 25lbs+ spike, but we may see less boost at redline without that spike!?!?!?!

Opinions?

 

idk? Good observation though...

 

It may be possible to still get a good spike, as many people have a very hard time keeping the stock turbo past 22psi at redline, even with a 30 psi spike

 

I think the main way a dump 02 housing helps is to reduce overall exhuast system back pressure

By venting some exhuast flow outside the system it aides the exhuast sytem by reducing the over all back pressure
