anyone seen these things i guess they are somewhat new to turbo's but i wonder what you guys think. would you try one?

would this be beneficial on a large single turbo setup?

Never seen such a thing

 

i hadnt either and ive been around turbo stuff for years, even older friends with more experience than i in turbos like it, the price from that company is obviously out of control, anyone could make these things out of stainless and be cheaper, but could this be beneficial on a oversize turbo? i would like to put one on a first gen cummins to use for towing/DD fun but not sure how it would work out, dyno tests have shown over 100ft-lbs increase and it comes on quicker
anyone have any other input?

 

horsepower increase? i highly doubt it. it may let your turbo spool quicker(or choke it) but theres no way it would give you any more horsepower to speak of

 

with twin scroll housings and split exhaust manifolds like we have that is not beneficial and will not work. it will block off the back 3 cyls exhaust flow.

when using a common collector that is not divided and a twin scroll turbo housing this will double the velocity and volume of the exhaust going through one of the 2 scrolls therefore making the turbo light faster.

when using a common collector that is not divided with a turbo w/o a twin scroll housing you might see a little bit better performance but you may also see poor performance due to the loss of exhaust flow.


i hope this makes sense to ya'll

 

Makes sense to me!

 

benjamin, thanks for bringing that to light, i didnt realize that the manifold would be blocked
