Have you considered HP variation from dyno types just like the classic Dynojet, Mustang Dyno comparison (500rwhp Dynojet is = to ~467rwhp on a Mustang Dyno MASSIVE difference).
dyno variance then doesn't even consider standards (SAE, STD) and correction factors along with graph smoothing.
Then you are only guessing drivetrain loss as a fixed percentage, whereas it won't be fixed but variable.
So all in all you can not directly compare ANY rwhp number to an SAE Net number.
It's like saying who has the most money, an American with $10 or an Australian with $10. Well you not only have to consider the moneytary value as in exchange rate, but also the spending power of the money in each country.
It's always more complex than it looks and bhp numbers shouldn't just be thrown around with unproven and un-theorised claims such as "it's way underatted and must have nearer 574bhp".
Rant over, but this kinda thing just bugs me. PEACE

which car would be faster..... C6Z06/blown C5Z06?

A formula I've to compare Dynojet to Mustang Dyno is simply divde the Dynojet number by 1.07 and this should be pretty close to the Mustang Dyno reading (from real life numbers I've seen, it appears to be pretty close).
So in your case:
445 / 1.07 = 415rwhp Mustang Dyno
450 / 1.07 = 421rwhp Mustang Dyno
So when using the 15% rule (or any other drivetrain loss esimate method) it makes a massive differance.

The 06 Z06 is only 3130 lbs. The 02 and 03 Z06 are 3200 lbs. How is that lighter?Nate

This is what i've seen on the 06 Z06; http://gmhightechperformance.com/features/0505htp_z06/ and http://www.caranddriver.com/article....ticle_id=10243
It doesn't weigh tons more but it does weigh a little more. I'm sure just like ever other car, some are a little heavier depending on options and what not.

FWIW
The Z06 is bone stock. Weight is 3060# with no gas (based on 18 gal tank and 6.25#/gal) on certified scale. Removing the air filter adds 2-5 hp based on the 3 forums I visit. Jim Hall said the stock filter flows so good that there is little left to improve on. Maybe the 20 horse is if the entire CAI system if taken off and air goes directly to throttle body, don't know just an idea based on two CAI systems claiming 12-15 or so hp gain.
Two cars dynoed on the same dynojet and then the dynopack in question. Treynor with his C6Z06 dynoed 469 on Newtecks dynojet without air filter. Take the 5 hp for no filter off and you get 464 hp. On Synergys dynojet he got 469.5 hp or a gain of 5.5 rwhp. Another corvette dynoed on the Newteck and then on the dynopack with us last Saturday said he lost 6 rwhp on the dynopack.
And Lou G., who has a dynojet, said in a post he felt the dynopack dynoed a lilttle less or about the same as the dynojet. So one car dynoed 5.5 hp higher on the dynopack, another 6 hp lower and Lou G. feels they are the same.
Edit. There have been a few 460 rwhp dynos. Myhardtop had a high of 465 on Lou G's dyno.

My Dad just recently bought a C6 Z06, and i must say that thing is a frickin beast. He had it stock for about a week and then he got bored and started modding. He dynoed it 2 days after he bought it and it dynoed at 452. That is rediculously fast for a factory stock car for under $80,000.

The new C6 ZO6 is beatable. But just barely. You better have a seriously modded N/A engine. Head, and cam alone won't cut it. Just look at my sig, I got what it takes but we ran so even, but we shifted differently so we traded the lead back and fourth all the way up to 175 mph. I was willing to keep going but it was obvious he let off. I am not saying I won, but I'll take a tie against that monster any day. I know should've been post in Kill Stories but it seemed appropriate since the comment was made about the stock C6 ZO6 being unbeatable.

The saying goes run what you brung, that's what I did.
He may very well have been disoriented. The fact remains
he knew he had his hands full. I wonder if he'd believe
no nitrous, N/A setup and 80 less cubic inches ran him to
the wall like I did. Hope to meet him again on the E-Way.
