Anybody using one of these??? Just want to know if it is a quality piece. Also, is there a noticeable turbo lag without the twin-scroll hooked up?

 

That's the SSAutoChrome manifold. If you search around, there are quite a few horror stories about them.

Although, I haven't seen a single one of the new ones tested, but supposedly their much better quality.

For the price, can you beat it?

 

Yes, there is noticable turbo-lag with the twin-scroll disconnected.

If you no longer want the twin-scroll setup you've got to port-match the (smaller) runner to make it efficient.

 

If you search around, you'll find none of those stories relate to rotary manifolds, and most of not all of the users on this forum seem very happy with their purchase. Most of those "horror stories" are in fact people with zero actual experience spreading myths, just like you...

 

Actually NZ, adrock3217 isn't "spreading myths". If you do search, you WILL find a few horror stories about SS Autochromes' products. Whether or not they are true is a different story, but there are plenty "stories".

 

just remember, you pay for what you get. ss autocrome or not, it's cheaply built and it will fail eventually.
the first thing I would do is weld some support tabs on that.

 

Go back and read my post again, particularly where I said "none of those stories relate to rotary manifolds", which is what this thread is about.

 

cheaply built? i thought they were fairly well built. *shrug*

25k on my turboback exhaust and i helped install one of these exact manifolds that dynoed over 300RWHP. *double shrug*

most people don't comment on their positive experiences because they don't feel like getting caught up in all the drama that surrounds this topic. sure they had problems in the past but the past is the past nonetheless.

 

wow, actually this is the first time I've heard anything good about ss autocrome? So with this being said are the turbo's still crap? Have the manifolds past the test of time? I knew there where a few people running them that liked them however after a few thousand miles they cracked and this was on a rotary? I'm not saying it to spread misinformation but I would love to move to a full turbo setup and if I could save some money on the manifold then that is awesome! Also how are thier wastegates, or should I stick with a name brand for the wastegate.

 

i don't see the point in replacing an s4 manifold. gains will be minimum, if anything at all.

but i have used the fd manifolds to 400+ hp on 3-4 cars, and know a few more people that have done the same...no problems so far.

 

Don't mean to burst your bubble here, but I think you should've done some searching before saying that. I've commented about at least 10 horror stories I've had and dealt with regarding their 'products' on a rotary application.

 

cool, lets see some pics.

 

Never had a purpose for taking any, it was on cars they hired me to fix, not exactly picture material at the time.

 

Once again, personal experience speaks for itself. It is unfortunate that the products you dealt with weren't satisfactory, yet, you sharing your experiences, with SS Autochrome, is invaluable to many of us. Thanks.

 

It won't mean much, around here unless you have a full scientific analysis, with photo documentation, with receipt and videos of the entire life of the thing on the car, nobody will believe anything you say.

 

LOL, even with all that, I can still name a few that will say you fudged numbers, doctered the video, and then question your testing methods or sources for your test results. Yet many of these folks use the same methods for testing their "theories" and claim them true. Kinda brings to mind the oxymoron: virgin sex therapist.

 

convenient how nobody can produce pics.

 

Then produce some with documentation of it lasting 200K miles at 980*C. If not, pretty convient. I haven't seen any documented proof or evidence that they work.

Oh, and your welcome to fly to Michigan and take pictures for the forum to see.

 

all i speak of is my own personal experiences, none of which have been bad 'yet'. for the most part you get what you pay for and i'm not swearing by them as i anticipate some problems but for the price you caould buy 5 of these manifolds to 1 HKS unit or 4 full exhaust systems to any good name brand. mileage numbers if these things failed after 20k miles then you would still be ahead.

so far the quality didn't seem bad to me and as i sad my exhaust has more than exceeded my expectations and i plan on testing the manifold soon, maybe even with a dyno to see what gains(or losses) there is.

 

Well at least tell us what happened or posts links to what you've said before. "I've commented about at least 10 horror stories" means absolutely nothing.

 

LOL, you're the one that was saying search! But short summary, I've replaced 3 of their turbo's due to bad/failed oil seals after under 10k miles, had two of the 50mm wastegates they sell seize up (one closed, one in the open position), and I can't remember the number of manifolds. Most failures were simply the welds cracking and the result was massive exaust leaks, usually around the turbos flange itself, had one or two that I remember that the piping at the manifold was the culprit, but it usually was the turbo flange.

 

Oh thats rich. Thanks Rat, thats my laugh of the day.

 

On the other hand, my experience with the SSAutoChrome manifolds has been fine. It's not been my first choice but I've worked on several cars with them and none have had problems in 100,000KMs or so.

I wouldn't put any on my cars simply because I'd fab my own and all stainless manifolds sound "pingy" to me.

 

As I've said, their new stuff appears to be a LOT better than their original, the original stuff looked like someone just out of highschool who took a welding class was doing it!

 

show me ANY turbo manifold that's lasted 200k miles @980* C
