OK is the borg warner matchbox turbine wheel Size chart wheel large side measurement and also the compressor map says correct lbs which isn't the same as the turbo maps advertised with turbos sold. like everybody I'm trying to get spool and power
Running a Australian hemi 265 cubic inch straight 6 cylinder with a turbinetic t7268 at the moment single scroll .81 and it's full boost about 3600 3800 ish only revs to 6200 makes 570rwhp on the dyno here want boost all in by 2700-3000 rpm
And 600 +rwhp looking at my choices cheap borg warner airwerk's journal 6268 what other options I have just made me a twin scroll manifold and just seen the gtx3584r is single scroll typical
How do the garret journals go they are singles though vs borg warner or do i need ball bearing attached is garret vs borg warner

Sorry don't no how I got so many piks all up not intended here is a pik of my matchbox what u guys think #ad

 

Some punctuation would really help.
That turbo looks a little small, your off of the efficiency islands especially at the top end, I think you will be producing a lot of heat at max revs. I would go bigger, look at the s366 and see how it does, you can control where boost comes in with the turbine size.

 

Yes OK i am sorry about all the photo's .Is there a way to remove some ? All the borg warner s300 turbo's are 68mm turbines looked at masterpower but these at 64mm are single scroll . The matchbox shows I can run a 64mm turbine with a .92 housing will a 64mm flow 750 fwhp to get my 600+ rwhp
Thanks

If you need something exact, Bullseyeturbo has a variety of turbine configs. Give them a call. Their street billet s366 is a real good piece.
Of the s366s ive seen they came factory with .91 divide 80x74. But most of the import websites only show the smaller configs.

I have an s366 t3 .70 76x68 on a gm 4.3 Very mild build with the turbo mid mount and no two step or t brake to build boost. Stalling up just shy of 3000 and let the foot brake go and it comes up quick to 15 psi.

With the turbo up front it would need a larger turbine config.

 

Thank u
