So you gonna put a SC on your stroker and pumps out 1000bhp

With any significant amount of boost, internals will have to be strengthened and/or compression lowered, otherwise alloy block and parts will not survive.
S85 was designed for high RPM, not force feeding. ZR1 uses standard block instead of Z06 block as the latter was not durable enough for a blower. Standard block and internals were also redesigned with stronger alloys, shot peened and forged parts to handle the increased stress.
Bolting on a blower is easy, modifying an engine not designed for forced induction to last is not.
There are several c6 zo6s running around with the tvs1900 putting down 700rwhp on the stock bottom end (though headwork was done).

As a general rule, that's true. But then again how do you explain the success of the E39 M5-S3?

If this supercharger kit comes, I hope for sure that it will be one that doesnīt blow up the engine. I want it to be "stock-reliable", but then again, itīs ESS we are talking about, they know these things!
Keeping the boost below 6lbs shouldn't require a compression ratio change. not much room for an intercooler.
At <$15k I think there would be lots of takers (I'm in). It would become the best horsepower gain per dollar of anything out there. NOS is good bang for buck but you need to constantly fill the bottle.
It would require interesting intake manifold change to work with only a single S/C. Not much room for dual S/C's - perhaps need a raised hood ?

In addition, 997TT Sledgehammer built by SPI making 800+ awhp with a pairt of gt35s with stock internal. Member KeithTa's 997TT built by Protomotive making 700+ awhp with stock internal as well. I think it's doable for our engine with very low booost (6psi).
I'm looking forward for the final pricing. $10-15k is too good to be true, but bargain always good for end-user/customer like me.

You donīt need any rebuild on the hood, there is plenty of room under there. Havenīt you seen the G-Power?
I'd be concerned about cooling. Even low-intensity track work in an unmodified car at 70 degrees is beyond the stock cooling system's capacity.
Also, what would supercharging do to the torque curve? It would be nice to have a solution that gave us some grunt at 3k rpm. Most of my driving is around town, and I frequently find myself at relatively low RPM in 2nd gear asking myself if this is really what a 500HP car should feel like. 5K+ is lots of fun, but below that, it's frankly disappointing.

What I liked about the AA Supercharger kit on my E46/M3 was that it retained the same torque & HP profile...There was just more power overlaid on the same power slope. Not like a turbo application which shows more of a surge.
