Hahn Racecraft Super 16g?

[talonsteve25]

There is very few dead end threds on this turbo. Just wondering if anyone has played with these? I just picked on up today and just wondering where it runs with the other turbos? It has the bigger exh housing so it must flow more in upper range? Any insight is appreatiated

From what i read, a long time ago, its a sleeper 16g. As in, a 20g wheel stuffed into a 16g housing. IIRC though.

I had one for a while. All it is, is a Small 16G with Syclone/Typhon 10cm turbine housing. Its not really that Super.

I'd ditch the 10cm and pick up a 7cm housing. You need a manifold spacer and custom O2 housing with the 10cm. The 10cm is more for non-turbo conversion FWD cars that can't handle the 16Gs hard hit. I had a 6cm housing on mine and it made a really fast spooling/hard hitting turbo at 23 psi. I could scare the crap out of my friends who never launched in a DSM before. I really liked it, but above 6000 rpms the 16G puttered out.


The oil feed is a different thread pitch. I think normal TD05Hs are 1.25, the Supers are 1.5. Not having a J-Pipe is really nice also.

I have had this turbo set-up for a couple of years on my 95 Talon Tsi. It is a very driveable turbo as the boost does not come on until 3400 rpm and it gives you more boost in the higher rpm range, because of the larger turbine. It works best at higher boost, like 18+psi, the turbo is sluggish boost under this. If I had it to do over again, I would not buy this turbo. The biggest problem I have had with this set-up is recurring exhaust leaks before the O2 housing.

Some things you will need to do to get the most of this turbo:
1. Port your exhaust manifold outlet to match the T3 turbine inlet of the Super16g turbo. (OR change the turbine housing to the 7cm housing as suggested above.)
2. Use good quality exhaust gaskets at all of the joints. I have had the best success with the copper gaskets sold by FFWD Connection.
3. Hahn recommends using copper rtv sealant instead of gaskets at the exhaust manifold to turbine adapter plate joint and the turbine outlet to O2 housing joint. My experience is that the RTV sealant just turns to dust and leaves you with an exhaust leak. At the exhaust manifold to turbine adapter plate joint use a stainless steel TD05H gasket (ported to match the ported exhaust manifold outlet). At turbine outlet to O2 housing joint use a 3 hole 2.5" turbo gasket, which can be had at various places on the internet.

I had it at 15psi and I was getting a full boost around 3600 rpm's. I didn't like the exhaust housing and had plans of switching to the 7cm so I could run a punishment o2 housing.

Using a 7cm^2 small 16g, I saw over 36 lb/min at 22psi and pushed it once or twice to 38lb/min (end of the small 16g compressor map) with the 7cm^2 turbine housing and a cam upgrade and pumpgas with an otherwise stock longblock. Being that the only difference is the cy/ty turbine housing, there's no benefit to the super 16g over the regular small 16g considering the small 16g can be seen to the end of it's flow range with pump gas and a faster spooling turbine housing.

If you'd like to push the small 16g compressor beyond it's map, you should just get an evo3 16g. That turbo could very well benefit from a larger turbine housing.

Thanks for the replies guys. I went to put it on today and found out like already explained it does not fit on the stock manifold. But i do have a 14b hot side, which is a 6cm? Im thinking of just putting that on and running it. Sucks to find out its nothing great, but what kind of power could i make with it with the 6 or 7cm hotside?

 

[dsm-onster]

It's hard to see the full potential of the 14b compressor with the stock 14b 6cm^2 turbine housing. Get yourself a 7cm^2 turbine huosing for cheap.

 

[talonsteve25]

No i mean im using the 6cm turbine housing on the super 16g.

 

[Bud92gsx]

Your not going to see the results you should with the 6cm housing..

 

[daren_p]

No i mean im using the 6cm turbine housing on the super 16g.

Exactly Matt is saying its hard to see the full potential of even a 14b with the 6cm housing, so your going to be even worse off with your larger 16g compressor . I too would recommend picking up a 7cm housing & you should be set Never understood the the "super" 16g's. All the lag of a larger turbo with the power potential of a smaller Plus add in the factor for more possible leaks with the additional adapter required

 

[dsm-onster]

It would be a nice turbo for a ka24 turbo build or a nice upgrade to a small t3 factory turbo turbo setup I guess. . . Never made much sense for a dsm to me either

 

[talonsteve25]

I dont much like this turbo anymore shoulda read before i got it. Oh well it was cheap. I still am aming for 400 awhp so i doubt this turbos for me! I do have a holset sitting here though i wish i could trade it for something bolt on..

Have you looked at the BEP Housing for the Holsets? If it's a HX35 or HX40, they have you covered. There's still some other work needed to install it, but that solves the manifold and o2 housing problems.

 

[GSXnoob]

I'm getting the BEP for my HX40. Don't trade the Holset. They are a very good turbo. The flow on them is high and they last forever. If you are thinking of selling it please pm me and I may buy it for a second car.

If the "super" is a small 16g, then you'll probably come up short on that 400awhp goal. It may be doable but were talking all the bolts on like cams, SMIM, big FMIC, etc to get all the flow you can out of that compressor & probably not happening on straight pump gas.

For a 400awhp daily pump tune, I would want to be looking at something abit larger, just to make the goal more easily achieveable. Whats a s16g typically flow when maxed, around 38lb/ish, this will fall short of your goal.

 

[bagged420a]

For 400awhp, you're probably going to want something that will flow atleast 48lbs/min

 

[talonsteve25]

Hey thanks for the replies guys my plan now is to just put the litte 16g on and play around with it then in a few months here make a manifold for the car maybe a top mounted design for the stock holset hotside because they supposidly flow more then the bep then just go with that! But for now im sure ill be happy with the little difference from 14b to 16g

 

[dsm-onster]

If you plan on using the stock hx40 hotside, you should really build a divided runner (paired 1-4, and 2-3) manifold. You can do this with a topmount configuration a bit easier. But otherwise your spool will be quite lazy.

Here's another option. . .

The super 16g turbine housing and your td05h turbine wheel that you currently have would do good with a 20g compressor upgrade. The hotside would likely flow about the same as a 7cm^2 turbine housing with td06 turbine wheel (common 20g hotside combination), but will likely flow that same amount at a lower required backpressure. Increasing the turbine housing size lowers the backpressure required to flow a certain massflow though a turbine. Increasing the turbine wheel size dies the same thing, but less effectively usually for the next full fram size up. So a 10cm^2 hahn super 16g turbine housing with a NON clipped td05h turbine wheel could very well flow MORE than a 7cm^2 turbine housing with a td06 turbine wheel, common to the 20g.

All you would need is to put back on your 10cm^2 turbine housing after having a shop swap in a 20g compressor. And then you could run a common t3 open manifold and have a HEALTHY 480-500whp turbo.

But compressor wheels are $180 and balancing is about $100, plus the manifold cost. You'd be better of just to get a bolton turbine housing for your hx40 ($250shipped right now), no need for a manifold, and it should spool about the same with a WHOLE lot more potential than a 20g

If it's OK i need to ask a question. Why should you build a divided runner (paired 1-4, and 2-3) manifold for the HX40? I was going to go with this manifold.

Because the hx40 stock housing is divided and to get full potential you want to have a divided manifold to feed it. It helps it spool a lot better.

 

[dsm-onster]

Yes. A divided turbine housing is about twice the size of an open housing. The exhaust gase pulses will see only 1/2 of the housing in a divided housing setup with a proper manifold. This is why the divided housing as a whole is so much larger. But it also does things like negate backpressure issues (HUGE gain) and forces ALL the exhaust gases to do work on the turbine alone (another HUGE gain).

Otherwise, if you run the housing with an open header, you'll be running a turbine wheel the size of a p-trim in a turbine housing the size of +1.2 a/r

 

[GSXnoob]

Good luck with the setup. I have enjoyed my 16G.

Bringing this back.

Did the Hahn super 16g use the td06 turbine wheel? I think it did, but I just wanted to confirm.


For some reason, this just looks larger than 1.9xx".
