Why dont we use mitsu 10cm2 turbine housings?

[PRESSURIZED]

The EVO 8 uses the 10cm2 turbine housing on their 16g type turbo, why dont we use a turbine housing such as that on our cars? We both have 4g63 2.0 engines, so it should not be too much different on either vehicle right?

We would gain a good amount of top-end with a turbine housing like that. Just a thought.

HRC Super 16Gs and 20Gs.

The 10cm Evo housing is twin scroll therefore it's closer to a 7 or 8cm DSM housing.

A 10cm housing on a DSM would be big time lag.

Any benifit to this? I could see this as being a pretty good upgrade to say my 50 trim with a mitsu 7cm exhaust housing. Twins scrools usually spool pretty quick. the 8cm like size with the spool of a 7cm would be nice.

10cm or A/R, generally isn't a useful term in defining how a turbine housing will perform. It's a ratio that defines the cross section area of the centerline of the volute in relationship to the centerline of the turbine or compressor wheel.

For a better understanding of A/R: http://www.turbobygarrett.com/turbobygarrett/tech_center/turbo_tech102.html#b

From that diagram and description you should be able to see that it doesn't mean much by itself

Basically it's not a good indicator of anything unless you are comparing housings that are in the same family.

The FP housing is 9 cm and it spools just fine. You can take a Precision bolt on housing for a dsm and set it next to a .63 4 bolt T3 housing and clearly see that the T3 housing is larger, yet they are both .63 A/R.

It is like trying to compare compressors by the trim, it is just a ratio. For example a T4 60trim flows 60lb/min where as a T3 60trim is the size of a T28.

I see what you are trying to say but you can get the 60lbs/min 60 trim compressor with a t3 housing. How bout saying that the sc44, sc60, and sc52 all run 60 trim compressors and t3 housings, but that each compressor flows a different amount of air.

That's still a T04E 60 trim wheel, not a T3 60 trim.

 

[GVR4592]

The SC60 and the SC52 are a TO4B 60-1 compressor wheel and the SC44 is the TO4E 60 trim compressor wheel. The 60-1 flows 60 lbs/min and the TO4E 60 trim flows 52 lbs/min. The T3 housing you are reffering to must be exhaust housings, because you can't fit those compressor wheels inside of a T3 compressor housing.

 

[1SloColt]

They are all 60 trim wheels by ratio, which is what keltondsmer was trying to say, but you can get them with t3 exhaust housings. I was trying to clear up the point keltondsmer was trying to make because i read it a couple times and I could see where it could be somewhat misleading.

No, there is a T3 60 trim wheel:
