I have been running a 7163 EFR and I am bored with it, the S257 isnt a whole lot better in the way of flow, so I am considering one of Hahns offerings. They do Precision turbos and I am considering a 6262 CEA. I do a good bit of drag racing so the slower spool wont be that huge of an issue. Anyone in here running the newer Hahn setups? I have tried messaging and emailing them and have not heard a peep back, so that makes me a bit nervous as well

 

How about https://agpturbo.com/

 

Thats is an interesting one. I would need to do some digging to see what I would need to make it work

 

AGP is well known in the Dodge SRT community. If it was my choice between them two, I would go with AGP.
That's a serious turbo you'd picked? Going to the moon with your little Balt? Lol..

 

Ive seen some posts about not receiving Hahn products as of recent. Mainly on the Cobalt SS Community fb page but enough that it seems as though majority are out of luck after purchasing.

 

I haven't heard anything about Hahn in a long time. They never had a great reputation here. Their intake manifolds were popular because they were the only option for a while. Their intake manifolds were also popular because it was basically guaranteed that at some point in time, you were going to blow the welds on it apart and then they were going to blame you for not having a good tune.

Have you looked into other EFR turbos that can use the ZZP turbine housing? Alternatively, do what I did. ZZP T3 manifold. Pick your own turbo. Have a downpipe fabbed.

How much boost are you running? The 7163 is capable of 60 lbs/min.

 

Sure am! I laid down an 11.68@130, but its all back end. Have the 60' and 1/8th about as good as I can get it, and I have tried every trick in the book. I figure i may as well just embrace the fact mine seems to be a top end MPH car and pour it on.

 

I think the 7163 is about as big as we can do on the EFR frame. The Precision 6262 flows 74lbs/min, and I think the ball bearing option would improve the lag somewhat, but being I'm using it for drags, wont be a giant issue. I wish i knew how to set up a downpipe. I lack welding skills myself. I'm on 32psi now, but the larger turbo I wouldnt need that much

 

I can't weld either - I found someone to make all three downpipes that I've used on my car. Plenty of fabricators out there. My last one is a basic ZZP downpipe. I sent them my PT5557 and they welded a new V-band on it to match their downpipe.
