by having a "splitter"., interested to know what does it acheive?

http://msengineering.com.au/exhaustsystems.html

quote: The splitter position and length is all very important to get the most from the system. The short one off a TDO4 used on a VF turbo will give poor results, and must be lengthened to suit the Vf turbo. The waste gate only opens to 30 odd deg, most of the air flow from this flows directly into the path of the main flow, this reduces gas flow, creates turbulence and increases the exhaust pressure between the exhaust valves and turbo. Hold them apart for longer reduces the size available for the main flow to expand, so it is important that the splitter be as short as possible once inside the collector, but it must be a neat fit in the back of the turbo giving an optimum seal.

ahh thats really helpfull bro! didnt realize they were so important! should i be in need of one? since iv put a vf34 on recently? or is it expensive to get one made up from sayyy RMS?


Cheers

should cost no more than 5 bux if you organise measure measurements, what is more is labour...if you can cut metal and weld do it yourself!!!

Hi all...

Bringing this thread back from the dead...2007!! yeah


Scouring the Internet today trying to find the proper dimensions for my dump pipe splitter...
I have an X force dump pipe and a VF34 P20 turbo..

I've narrowed it down to the following..for a VF34 and in fact all Ball bearing VF's

3mm thick
60mm high.
12mm inside the dump
33mm outside the dump mouth ( into the turbo exhaust cavity)

This also compensates for a gasket thickness of 1-1.3mm crushed..

But the left and right spacing in the dump pipe is a mystery?
Weld it in the middle or directly between the WG and the turbine outlet?
more towards the WG or the turbine exhaust?

Ie see attached picture.

Specifically dimensions A and B..

I know from an earlier post in this thread specifically BXTs who also has a X force dump pipe..
I notice his splitter is not directly in the middle of the dump pipe..
Can anyone shed some light on this dilemma??

PS if you want to make your own splitter..

Ball Bearing VF's (VF 22,23,24,28,29,34) 33mm Sleve Bearing VF's (VF30, 35, 43) 27mm
All TD04/5 22mm


Cheers and thanks in advance..
