the hyberboost is metal, and has a piston/spring, the 710n is plastic and has a diaphram

wat would be the diff performance wise?

There is no performance gain it's just a simple matter of it either working or not. There are guys with S4's running 710n's with over 400 awhp. So, to make a long story short those piece of shit divertervalves that cost upwards of 150 bucks don't work any better or show any better gain than one that costs 30.

The spring can be changed to accommodate different boost pressure ranges. The 710n is what it is.

The piston type valves are serviceable. A wipe down with a rag and some new synthetic lube and it will be good as new. The 710n has a diaphragm that will eventually wear out.

The good piston type valves cost as much as several 710n valves.

I have one of each. This way I can swap the 710n back in when doing an oil change. Then I can strip the nice one down and toss it in the dishwasher. Then install new o-rings, lube it back up, and swap it back in whenever.

Performance wise, there is no difference. The response should be more consistent with the piston type since the diaphragm will wear out. This wouldn't be a concern in most turbo cars but I've been in an S4 with a intermittent boost leak. In most cars that would have just been annoying to live with until the correct part got swapped. In the S4 it caused a turbo to overspeed and nuked it. This is why I don't really like diaphragms in the loop. At least the S4 got RSK04s. [:D]
