Really, you had to go and be that guy? 
Everyone knew exactly what I meant. If anyone here has front wheel horsepower...
Most people get confused when using 'hp', as they automatically assume to the ground... it's a minefield of stupidity. Technically, though, you're correct. I think I'm going to have to start some silly acronym like 'flwhp' for the people who look at you funny when you say hp isn't a measurement to the wheels...

I do like your "minefield of stupidity" comment, I hope you don't mind if I borrow it sometime.

He is technically incorrect, we will continue using FWHP here and you should too. We are not going to change our way of referring to FWHP because of a newby who grew up in the ricer world...I have no idea why he had to be "that guy".

My 2007 C6 with centri and a A6 pulled a 09 Z with intake and that thing only made 530 whp, so something is WRONG with this picture. One thing I did learn, the A6 did not like lots of HP and boost. You would paddle shift it and by the time the tranny thought of shifting you were banging the rev limiter in full boost. If you think that is fun, not so much. I would like see a C7 with 7 speed and blower do this same run,

In the ricer world, FWHP may be front wheel horsepower but in the real world, FWHP means flywheel horsepower. 
The acronym "FWHP" has many meanings of which front wheel horsepower and flywheel horsepower are BOTH included.
http://www.acronymfinder.com/FWHP.html
I use FWHP for flywheel horsepower and everybody here understands what I mean just like everybody understood Theta and obviously you did too...I don't know why you felt the need to be "that guy", lighten up and enjoy the ride. If it bothers you that much, may I suggest you visit the Honda forums...there are no front wheel drive Corvettes.
BTW, there is no horsepower relationship for the acronym CHP so you are technically incorrect. (Put CHP in any search engine and see what you get...nada for horsepower.) BHP is the technically correct engineering acronym for horsepower measured at the crankshaft but most non-engineering people don't know/understand that term. Just use FWHP and you'll blend in just fine here.

For any of you guys on here doubting the performance of a C6 Z-06 has neither ever driven and or ridden in one... They are stupid fast. I had an 07 and just got my new 14 and they isn't any comparison between the two performance wise. I'm sure a s/c car will pull pretty well but I'm still doubting it'll run away from a slightly modded Z-06.

C6Zs can run the gamut of fast to insanely stupid, no denying that. But I think you're underestimating the C7 platform with higher numbers.

Perhaps, but, having said that I've owned both cars. My Z-06 would literally get sideways on the freeway from a 70mph punch and this new car albeit new and not fully broken in yet doesn't even come close the the power of the old car. Now back to comparing an s/c C7 running against a "slightly" modded C6 Z-06 there always the whole weight differential and aerodynamics issues to be debated separately, but raw hp vs hp I think the Z-06 still owns it based on torque rpm curves. The Z-06 will pull harder longer than a C7 period.

Stock for stock, a C6Z vs C7 is no comparison. That 427 top end is magical. The only thing holding the blown C7 back is the lack of top end. Adding a blower cam basically gives it the top end back that was stolen from it for friendlier mileage numbers.
I've said before that the 427 in this car would be a beast. That engine was the crowning achievement in GM's small block production history.

You still have to remember that the C7Z is still essentially a blown LT1 (compression ratio and such aside) with a PD strapped on top. It also, most likely, has changes in the fuel lobes and a larger fuel pump, etc. The C7Z has absolutely trounced the C6Z on all fronts - hell, it made the ZR1 look bad.

Of course, and I don't want to skew the argument to C6Z vs C7Z because that's unfair. I guess we'll know for sure soon enough how similar/dissimilar they (C7 vs C7Z) are, but it's (hopefully) not running on unicorns and happy thoughts.
The magic of that car will still be the engine (and a usable 1st gear like the C6Z had). There's not a lot of room for improvement over the Z51 chassis aside from aero which we've seen. Weight reduction doesn't seem to be very easy, and I have everything broken down to barebones at the moment (it's just a lot of polycarb).
As it sits, a PD on an LT1 should yield exactly the same (if not better) curves and performance than an LT4 would (up to a certain RPM where cam and fueling differences kick in) on a bare engine dyno. The centris are going to act differently, of course, but they do mate well with the C7's low-end grunt out of the gate. The only real hamstring to a blown C7 is the camshaft. That's a real bummer - and because of that, the C6Z will eventually win because of the unrestricted high end. The heads and manifolds on the C7 are excellent for something right out of the gate.
It's a shame the cam in the C7 is so damned hard to change.

I guess I just see a lot of promise in this platform compared to the C6Z that was already very well done by the factory. I'm treating the C7 like the ZR1 platform. The power will come from forced induction and fueling (as you've seen from the 1000whp cars being built on here).
My golden rule is that "there's no replacement for displacement", but in the 'new world order' of these types of cars, that's changing quite a bit. We're all a bit warped when we think of a 378 6.2L as small.
