Does the Inconel manifold eliminate most of the lag caused by the bigger turbo ? I am just curious what the driveability is like with this setup. I have an S4 and am seriously considering the 3+ conversion when it is available.

power delivery is seamless. driveability is perfect. the car feels like it came from the factory with this setup.
there is no stage 3+ for the S4, but stage 3 is in development.

it is just a constant stream of power(no 2300 rpm kick of K03/K04)

The turbo lag on my APR stage III is like the turbo lag on a Bimmer M3 =)

cast iron manifolds?

I read somewhere that inconel does not retain the heat as compared to iron. Is this true?

thanks

I wouldn't have thought of it myself, but you can almost think the car is a naturally aspirated one the boost comes on so smoothly. No lag at all if you're anywhere in the neighborhood of ~2500 or so (granted, the car I drove had Shrick cams in it), and above that it's simply a rocket ship.

if you have an S4, you must not be talking about the Stage III kit for the 1.8T though? You have a 2.7T motor... ?

BTW, letsaudi - inconel is a different metal than steel, just like iron is a different metal. it retains heat MORE effectively, rather than less (meaning more energy gets to the turbo's turbine), and is much more tolerant of heat-cycling (no cracks, deforming etc)

The kit is absolutely amazing. in my ~1hr drive, I couldn't find a single thing that wasn't totally OEM in nature, from sedate driving to WOT mashing. Typical APR A+ quality.
