It has to make more then 440hp. I made 410 with NO ported exhaust or head, stock s3 o2 housing, full 2 1/2" exhaust, 2 1/2" cai and no race gas.
Port work or headwork isn't going to improve compressor flow. The 44lb wheel can only make so much power. The porting is only gonna allow you to get every last HP out of the turbo without restriction and improve your power band.
If someone makes more than that more power to them.
The dyno was a last min. thing Neon Dan called and told me our local dyno shop was moving and the owner said he had time to do one more dyno session so he called me and I went down. Spike was 27-28 with 110 HOM falling to 23. Shop temps were killer 101-104 and I later found I had a boost leak at my ED coupler and TB and also my valve cover after installing the DCR oil mod. Tuning was a real pain the SAFCII was only on for 10-15 miles so it was really fighting us I know there is another 30whp in the midband with a better tune. I think with cooler temps and leak free 430-450 could be had!
Nice graph. What is does your fuel system consist of?

Not bad.
Looks to be about 20-25whp away through the whole graph than ours. We also made 413whp at 6200.
We will be going back soon after fixing a few things

Yea the midband was really hard to tune some pulls we would get to dance around 12's then the next it would be off the chart No doubt I have 20-30 in the mid band then the afr kept droping just before 6500!! Oh well I'm happy with the results, it was the 1st time I have ever touched a SAFC, install was easy tuning is a little different

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]

Sorry I should clarify, bigger turbine wheel.
A TD06 turbine wheel mated to a 49lb compressor wheel (50trim) would be very interesting
