OOOOO the intakes (mind you the 06 box was better than most aftermarkets) and the headers are good.....big deal.
The manifold from a VQ37HR would show gains if they could get it to bolt up, it just doesn't....meaning, there will be intake gains made....for sure.
You're speaking out your ***, there aren't many mods because the engine has been to market <1 year. Companies are SCRAMBLING to get stuff for it.
Listen to the people with the cars, the tuners, etc. the HR is better factory, but far from maxed out.
It's maxxed out. What you got is pretty much what you get, my friend... The HR has been out for a year now... And still no mods other than cams, test pipes, and cat back exhaust. Intakes do nothing for the HR.

Test pipes and exhaust give 10-20 hp, depending on a lot of things. If an intake manifold in combination frees another 5-10, and tuning is able to pull another 5-10 with those mods. Add a flywheel, gears, and DR's and the car is deep into 12's. I don't understand why you say there aren't mods available or in development. There are plenty of turbos in the works, what more do the DE's have, plenum spacers?
Edit - and if you're so fast, why isn't your name on ANY list here?

The same thing can be said when Z first came out people said it was maxed out to but you wouldn't know that.

Alot of the things you are stating is false.
When I got my Z in May 2003 there was ZERO aftermarket for the car. It took a full year before anything became available. The HR hasn't been out for even a year and there is already cams, intake, exhaust, test pipes and ECU tunes.
When I bought my car NONE of those were available for quite some time.
The HR engine is better then the DE in every single way. Besides the forged internals, VVL is one of the most important things. No stand alone has full control of VVL yet, but it's on the way. My DE before FI with zero mods dyno'd 227WHP (No corrections). An HR was dyno'd stock on the dyno with no corrections made 260WHP. That has nothing to do with the new HR headers because all headers are going to do is give you torque down low and very little if any peak HP. Most of it has to do with VVL/Exhaust/Cams.
People will figure out how to extract more HP from the HR soon enough.

I'm not 100% sure on anything because of that, but he said the factory rep's said the 09 is still a Z33 and gets the 3.7, the 2010 is unchanged from 09, and then 2011 is the new chassis.
We'll see, makes sense to me though.

Tires alone should be worth .2, a flywheel another .1-.15 in the 1/8th. Extra power up top will give even more.
I'm not saying everyone will get there, but for a few grand (3-4) most people *could* see 12's, and a few can get solidly into mid 12's.
Yeah... I'm committed to staying NA. I really wish there was a less expensive way to extract power from the Z (whether it's a DE, Revup, HR).
I've reached the end of the bolton path, now cams and head work are gonna cost me about $3800 and that's with the core charge taken out, then you got installation $$$.... <sigh>....
Then I gotta start building the lower engine for more compression/ rpms... More $$$... Another <sigh>...
