Come on now Walt.
At that point the turbo becomes the restriction.
I figured the exhaust side is a big restriction atleast on my setup. But maybe not. 440hp may be the limit.
The scroll area on the S3 is listed at 10cm2 which is about as big as it gets for that size turbo. A TD06HR wheel would be the upgrade but what kind of affect would remain to be seen. I'm not even sure they make a reverse rotation wheel that size?
It makes no sense to go any bigger of a wheel other than the 44lb. You can go 10s with this turbo. If you want to go faster....its time to step it up [plain and simple]
