Op6 Turbine Wheel

[shinobi_s14]

Hey guys,

Need some help, just wanting to know what the diameter for the turbine wheel on a OP6 turbo was.

Cheers in advance,

John

Same as all the other ceramic wheels. They're all the same as far as I know.

Ohhh okay. I just wanted to know the diameter so if anyone had one out of their car and could get a measurement that would be great

I just checked a broken off turbine wheel from a 21U and it measured 52mm (or close enough) at its widest point.

Id post a pic but iphone wont let me.

Just to be a little be clearer this is the measurement that I'm looking for

Thats the exducer side... I wonder what you want that measurement for?

Wanting to highflow your turbo in a weird way or wanting to fab a split dump of some sort?

[shinobi_s14]

Yeah mate is making a dump for me so he just asked me to find out the size of it

How knowing that measurement will help with making a dump ill never know.

[shinobi_s14]

Umm to know what size pipe to use to make proper seal between the turbo and wastegate on my split dump?..

[R31Nismoid]

Knowing how wide the turbine wheel is has no bearing on a splitter for a split dump.

You need to know how far from the wall of the housing to just after the exit point of the turbine outlet. The dump is always going to be larger than the turbine wheel and it's outlet. Split or bellmouth (bellmouth being proven many times over more effective, and cheaper)

Get your mate to make you bellmouth dump with a nice transition back to 3" and enjoy making a few more kw's.

Saves time and works better on most internally gated turbos.

This. Tried, tested, proven.

Get a bellmouth dump.
