I searched and could not find any answers anywhere.. I was found that O2 dumps yield the most power gains (over o2 housings at least), but are obnoxiously loud [to some]. I was wondering people's thoughts putting on a dump, and running the wastegate smaller diameter exhaust parallel to the 3" exhaust and merging them together just before the muffler.

Thoughts?

Thanks

 

sounds like a waste of time to me...and running a dump tube all the way to the back of the car? pointless

 

I agree...waste of time and materials if you are going to run the dump tube half way down the car and then recirc...Dumps are loud when you want them to be...Once you are WOT & 15 psi or so, yes they are loud, but what Evos at WOT aren't loud anyway?? During normal daily cruising you can't tell a difference between a recirc 02 housing & 02 dump...Collin @ Toxicfab will be releasing an 02 dump very soon & I will be getting the first one...if you have any questions let me know!

 

i would like info on the new toxic fab dump

And I was totally thinking that it was going to be waste of time/resources.... just double checking lol.

I might ask this part publicly, since I figured it would be good info to know.....

I was wondering what all lower intercooler piping that this will be test fitted with?

 

Just use a regular o2 housing.

 

MAP makes a downpipe that merges the wastegate gases in further downstream, FYI:

 

The Toxicfab 02 dump will work with any licp, BR, AMS, ETS, etc...I will be using a BR LICP with mine...

 

wow, I had never seen that map piece, I am gonna look for some more info on that as well.

 

rather than an o2 housing, going with an external dump would net approximately how much more horse power?? 5 max?

and good to know about the toxic fab piece... I plan (at the moment) to go with the nisei setup.
