How much power will ASR turbo upgrade make today?

If you're like me you have been following the ASR turbo upgrade thread, and it looks like today they are finally putting it on the dyno! It has a huge intercooler, the upgraded twin turbos, exhaust system, intake system, and I believe I read meth injection/race gas. So what do you guys think it will put down on a dynojet?

I would hope more than that...

$5k+ for a turbo upgrade that yields 50whp is a huge rip off.

What is the most STD power people have made on stock turbos? I did a quick search and found:

91 octane: 391whp
91 octane + meth: 416whp
93 octane: 393whp
100+ octane: 437whp

Running race gas (no meth), we are already at 470whp. And it is still at 470whp at 6500rpm which is 70-90whp more than we usually see with stock turbos up top. Virtually no top end roll off which means there is more left in the turbos. Full spool at 2500rpm too. It's nearly 100f in the dyno run with 80% humidity. We are taking a break. Weather is killing me :/

Also, these are NOT one shot glory runs. We are doing repeated runs on a hot engine in miserable conditions.

Still more to do today and tomorrow. Meth testing on Monday. So far, things are looking great.

It would be nice to see some 93 oct runs rather than just race gas. 99.9% of people dont use race gas for daily driving...

99.9% of people with 335's as daily drivers aren't going to have all these mods either. Or at least 95% won't have them. Either way, I'm willing to bet that if someone goes through the effort to incorporate all of these mods, they are probably pretty likely to run race gas as well.

Not necessarily true. Plenty of people can justify spending $5k on a turbo upgrade but can't justify spending $6k more per year in gas. Theres a point of diminishing returns when modding cars.
