Switchblade turbo

HeavyAssault · Mar 2, 2014

I'm sure some have seen this around the diesel community. I figured I'd post this for those wanting something different. The most interesting part for me is the EBP runs lower than BOOST PSI.

I don't think there is ANY room under a 6.0L's hood for something that big hangin off the turbo.

What ever happened to the ATS version?

I know the guy that helped develop these. Pretty neat design but never seen one in action. Also made locally to me

Excuse my ignorance, but isn't this essentially the same idea as a standard VGT set up, just using a different mechanism to achieve the result? What benefit does this have over the traditional VGT?

This should be posted in the 6.7 section. The turbo in the picture is exactly the same turbo I stuck on a 6.7 and mostly all the aftermarket kits use.

If I'm correct the vgt shrinks the outlet of the turbine housing vs this that in theory actually makes the housing smaller. Vgt would increase spool up through back pressure, where as this would increase it by accelerating the gasses across the turbine. In theory I would assume that the vgt could have more negative effects vs artificially shrinking the housing.

I posted this here due to the wide ranging applications the turbo can support. I know plenty of people want a big single non-vgt on their 6.0L.

I don't disagree it's not likely to fit but anything can be done with enough cash.

I want to try one, seems like an awesome idea

Isn't this pretty much like a diverter vavle

Not really, diverter still adds back pressure where this just utilizes it

Also with this setup it would be more controllable then a Diverter valve. More precise.

There are two major differences between the Switchblade turbo and the current VGT's, one is that it has only one extra moving part in the turbine housing vs 30 to 40 in the VGT's, the second is that it is about 20% more efficient than the other VGT's due to the fact that there is practically nothing in the exhaust flow in the open housing phase whereas the others vanes, even in the open position, are permanently in the exhaust flow and the flow has to deflect off them to get to the turbine wheel. Oh and it is currently used in a range of turbo sizes from a TD05 for a Suburu to one for a Caterpillar 3406. The size used is determined by the engine size.

This was the last I remember hearing about it

Although some of your statement does have merit... it is not all entirely true. There are only 11 moving parts in the turbine housing (9 vanes, 1 unison ring, and 1 actuator swing arm)... not 30-40 :fustrate:

Also I agree 100% with your statement about the vanes in a typical 6.0 vgt turbo will become a slight restriction. On the other hand that simple switch blade will not be as precise at adjusting the exhaust flow as our typical 6.0 vgt turbo. Everything is give and take in the turbo world... therefore it is kinda like a non-vgt turbo that is able to direct the flow a little bit like a vgt... kinda like a middle of the road.

It is exactly as precise as the 6.0 as it is a stand alone system that controlls the vane based on turbo rpm, back pressure and boost. At take off it reduce's the a/r by approximately 2/3rds until the control parameters are met. It is bluetooth equipped and you can monitor the data in real time on an I-phone or I-pad. You can also connect it to your laptop to change programming, log date for review, etc.
I actually have one on an 02 Dodge 3500 and it makes a huge difference.
