Hey guys,

Just curious...I've been trying to find information concerning the Duttweiler neck...I've read about the flow benefits, and the purported 22% flow increase.

In driveability and performance terms, what have you guys noticed? Very noticeable gains? How much does it affect power? Turbo Lag?

Any info would be much appreciated!

I've got no numbers for you, but considering how popular it is, I would think it's worth it. I've got one on my car but I don't know the numbers difference between with it and without.
 
I just got mine put on a couple weeks ago. I could def tell a diff in spool up time. It cut down my lag time quite a bit.
 
I have one on my car I can't say you will feel a seat of the paints diff but you will see better #'s at the track.
 
Your boost should jump up 2 psi. easily at WOT so lower the wastegate adjustment BEFORE you floor it after the install.

Good mod. along with the hollow cat. option. ;)

Assuming you are running maximum boost for your octane level like we usually do. :cool:
