non vgt turbo exhaust housing questions

[DoubleDpsd]

Is a divided housing required to do a diverter valve? And what is a s475 that windrunner408 mentioned in the other thread? thanks for the help

[windrunner408]

A divided housing IS required to use a diverter valve because a diverter valve shuts exhaust flow off to one side of the turbo exhaust housing. However, i have heard than custom up-pipes built such that they flow from one side of the engine into one side of the divided housing can actually work better than a diverter valve.

I s475 is a 75mm compressor wheeled turbo. s480 is 80mm. etc. just like a s362 is a 62mm turbo. Hope this helps.

thanks for clearing that up. will avoid the diverter valve route.

the diverter valve is a good idea depending on the setup..

[windrunner408]

Is it possible to get a 62/65/70 with a divided housing?? I could be wrong (and probably am) but it seems when I look at turbo options at bullseye that .70 housing is only available in an open t3. Greg, I know you looked into this more. What have you found??

[DoubleDpsd]

what's t3? I think i've seen t4 also...

[windrunner408]

I believe it is a housing flange size. The part that connects to the up-pipes. Greg is BD-diverter valve built for a t3 or t4 divided housing??

I like the idea of a diverter valve because it makes it possible to use a larger turbo which will move plenty of air at high rpms and still spool fast enough to be streetable. But, they are expensive and add compexity to the turbo setup...

you can certainly get a .70 divided housing just need to specify, but they cost a lot more, and a gated divided housing is even more than that.

This stuff can get expensive quick.

bd's valve I believe is built for t3/t4 flanges

I know BD makes a couple different diverter valves. one for the T3 to V-band, one for T4 to T3 and one for T4 to T4... I think the T3 to V-band is the only one that works with our truck without lots of custom fab work
