What do you guys make of this?

Wow...is the chrysler style exhaust housing even still in production?

[iTurbo]

Yeah, I was surprised they would make this too...they also have a new Mercedes version that looks similar. ATP has made custom turbine housings in the past; maybe they will pick it up if Turbonetics drops out.

LOL! I was looking at it and my g/f saw it and thought it was an engagement ring! Maybe I should buy one and propose

[shackwrrr]

Well, I know what I am going to get soon lol.

[shackwrrr]

also could it be that the mercedes pattern is the same as the chrysler????

well this looks like it is lol

Ive been wanting something like this for so long!!! Now if one of the vendors came out with a matching DP... I wonder how hard it is going to be to build a downpipe that will clear the PS pump?

FWD has a downpipe, they designed it for people that have a t3 with a ford housing using a version of this same swingvalve, no reason it wouldnt work on an 8 valve.

I want to try the new ATP Cosworth turbine housing/swingvalve. It looks like a bolt-on replacement for TIII but you would still have to use the stock TIII O2 housing elbow/donut. I have no idea if this would actually work but would love to try it. I've been thinking of ordering a 50trim/stg II optioned with it for one of my cars.

Just buy one of these and any half assed exhaust shop can weld it to your existing exhaust. Instant 3" downpipe. Thats exactly what I did on my R/T and it works great.

From the way its written, I think they describe the flange as Chrysler style, but they made the product for Mercedes guys, not us. They obviously don't care enough to even mention this product overlap to our community.



For a TIII, if you want to change housings (turbo upgrade), this would make no sense. Just buy a normal t3 housing and use a normal ATP swingvalve.

That would move it to the passenger side a bunch, and has no flex in it. I could build a DP no problem, and will if I ever end up with one of these. What I was getting at is it would be a nice package with the ATP piece and a matching DP.

I think they made an error in the description because there is two new listings for the Ultimate Internal Swingvalve in their online catalog. The pictures for the Chrysler and Mercedes styles do show they are in fact different bolt patterns.

Too little, too damn late.

Honestly if you think about it, you are right. If I were building another 8v I wouldn't think twice about getting the TurbosUnleashed 3" swingvalve. While it's nice that ATP might be opening up to the Chrysler stuff, the fact that a stock-type no fab required downpipe is easily available and clears everything perfectly is enough to steer me towards what is already available.

I've never understood why they bias the W/G so much compared to the turbine wheel. IMO the v-band hole should be about 3/4-1" lower.

Doesn't look terrible to me. The wastgate hole will move a LOT more exhaust per size then the turbine wheel. Higher velocity gases from the wastegate slamming into the lower velocity turbine gases will probably cause more turbulence and more backpressure.

I can't understand why they made this product though. Maybe because they found it was easy for them to do after already making others.

Pretty sure this will work but Tyler already stated that he was able to USE the other downpipe. People cry so much about fitting things around there so Warren built a ridiculous long pipe 4-2-1 header and it still fit.

Gotta disagree with you on this one. Anything that disrupts the helical flow of the turbine is what makes things more turbulent causing greater backpreasure.

But ya, I never said terrible, just not how I would have designed it.

Rob I agree, but IMO, it still is a nice design. Light years ahead of factory swingvalve designs. IMO, moving V-band hole lower would make that lower bolt hole accessible (at least from the outside of the swingvalve). I would think it would need to be lower than 1" to make that bolt hole functional on the inboard side.
It is pretty strange why they would come out with this now. Did they just figure out there is a market for old school turbo Dodges twenty five+ years after they came out?

So if you can explain how slamming the wastegate gases right into that same flow is better then inducing a slight bend, I could agree.
Turbulence is a bad thing in the swingvalve area. Much worse then being forced to take a turn. The facts will be read out all day on the dyno. Turbulence will effectively shrink the size of the swingvalve, creating more backpressure, and losing power.
It is leaps and bounds better then any Chrysler style swingvalve, so much better that its comical to even argue about their design.
