Considering that TT's cost much more and SC's are just coming out without any aggressive tunes or pulleys yet its to early to call it.

I believe that when the dust settles stage 1 TT's and SC's will come down to the driver, SC's might benefit from the flatter torque delivery. The limiting factor won't be the FI setup it will be the block. The stock block is said to safely be able to withstand 500whp, with is obtainable either way. The one clear advantage TT guys have is longetivity. When we start seeing built motors the TT's will really take off, until then it'll probably be dead even.

I want to see a spec sheet that shows the stock block being able to handle 500 hp.

Well there's handling it, and then there's the question of motor life. I would imagine you are dramatically reducing the expected mileage to a rebuild.

As you increase the stress on mechanical components, you reduce their fatigue life dramatically. So highly stressed parts are going to fail alot sooner. If you keep the stress level low enough, those same components may last for an infinite amount of time. So when Nissan engineers design these components, they are shooting for x number of cycles to failure (maybe 300,000 miles at an average rpm of 3000 as a guess) at about 270hp max to the wheels. So if you double the max HP, you probably decrease cycles to failure at least 5-10 fold maybe more is my guess. But you'd have to know the actual increase in stress and the material types of each component to know for sure.

I'm pretty sure Forged said from their block inspection that they thought the engine could safely handle 500 whp.

No one's going to know how much power the engine can produce without breaking something until someone breaks something...

But completely tearing a block down and looking at the components can definitely give you a good idea of what you've got. These guys build engines. They should know what these things look like.

what does it look like? it's just a lump of metal. how can anyone tell by "looking" how durable an engine is?

Just in case you aren't being facetious. Those with many years of experience with building high horsepower applications can just look at that lump of metal and give you a good idea of the durability of said lump of metal.
I would imagine (because I am not one of those people) that you could tell by checking the thickness of the higher stress areas and where the block is braced or ribbed.
Take for instance the small block chevy, there are some blocks that have only two bolts on each main journal that holds the crankshaft in place. There are others that use four bolts on each main to hold the crank.
Which do you think would handle more power?

for our applications, Turbos will always outpower surperchargers.

and with the correct setup they will have near identical response.

Ay my Man, u got to post some vids. You reppin the DFW. Represent!

That is not a totally true statement, and which applications are you talking about so I know what your applying that statement too?

who has that written on paper from Nissan?

Still no dyno sheet posted?

Contrary to popular belief there is a lot of stuff inside that "lump of metal."
