I just wanted to know what are the differences between a 3D port 02 housing vs a standard port 02 housing for a stock (frame) turbo?

Pros and Cons of each?

Thank you!

BTW: I searched and didn't find anything, but if anyone knows a thread, please direct me.

 

I have no idea what a 3D port is so in for info lol

 

To be honest I really don't see a con with the 3d flange. Additional flow and smoothed transitions are never a con.

 

from MAP's website:

We offer this product with your choice of turbine outlet flange, standard or 3D contoured. The standard flange has been performing flawlessly for the majority of our customers since this product's inception in 2009, but there have been a handful of customers that experienced boost creep when trying to run lower boost levels (less than 25psi) with upgraded turbochargers. In general if you are swapping out your existing o2 housing for this upgraded unit and plan to run 25+ psi you shouldn't have an issue with the standard flange. If, however, you just performed a significant upgrade (complete engine build, turbocharger upgrade, etc.) and would prefer to begin the tuning process below 25psi or if you ultimately plan to run less than 25psi we recommend the 3D contoured option to ensure you have complete boost control.

 

anyone?

 

It's not quite the same application but the same principle.

When i was making my turbine outlet flange for my Evo X turbo conversion i positioned the wastegate outlet in a way that the flapper directed the gasses straight to the port when it was open all the way. I also radiused the entry to the hole and added a notch so the flapper arm had a little more travel.


(ugly as **** but twice as functional)

 

What info are you looking for?

Long story short, the '3D' version, helps prevent boost creep.

If you are going to buy one, there's no reason to not go with the better version. Yes, it's more money, but if you going to spend the time and money, might as well do it right the first time.
