difference between EVO III 16G and Super 16G?

[Mike_GSX]

Hi, can anyone tell me, whats the difference between
the Super 16G from Hahn Racecraft and the normal EVO III 16G?

Thanks a lot...

PS: I used the searching, but couldn't find something

That's actually a very good question Mike:

The EVO III uses a 7cm housing like the standard 16G series while the Hahn Super 16G's use a 10cm housing. The 7cm housing that comes standard on EVO III's and all non-Hahn units (no rhyme intended) promotes faster spool up. The only rationale I can think of for using the 10 cm housing (usually employed on N/T conversions) is that it may generate less heat as a result of having a larger outlet. I'm sure someone with more knowlegde of turbo theory can contribute more information as to the "why" part of the equation, but at least that helps you understand the difference.

Since you have run a 4G63, I would recommend the 7cm housing for the best streetability and reduced of spool time.

Cheers!

P.S. Did you manage to get those 0-60 times down?

The 10 cm housing allows a little more top end power due to higher exhaust flow but I don't think it's worth it on a street car because spool up is horrible, I see people all the time complaining of not spooling till around 4500 with the 10 cm housing. I think that the compressor wheel in the evo III is also bigger because the super 16G is just like a big 16G just with the 10cm housing but i could be wrong there.

Thanks for clarifying the "why" of it. As far as the wheel in the EVO, it's definitely bigger than the standard Big 16G version. And you're right on the super, it's basically a Big 16G with a 10 cm housing.

Thanks for jumping in,
