Default Full Bolt-on Dyno numbers?

I'm going to do American Racing headers, Soler throttle body, Attack Blue filter (until Jim @ Halltech can get me his CAI) and a Gwatney ported manifold shortly. Anyone have before and after dyno numbers with this combination or a similar combination?
I love the car but it needs help until I can get my supercharger system configured for testing. I know I'm jaded, but I haven't owned a car with less than 700 RWHP in more than 10 years.

Sounds like you & I are following a similar mod path... I do not yet have dyno numbers though, but am very curious where I'll end up!

My mod list so far:
Attack Blue air filter
Soler Performance ported throttle body
SoCal Porting ported intake manifold
AFE coated headers (ordered, not yet installed)

My dyno tends to read low, but it will give me good before and after data. It'll be interesting to compare notes.

I installed ARH headers, but have been holding off on additional mods until I see results from others. Ill be watching what you report with interest.
I'd really like to do a blower, but it looks like they are all going to be about double the cost of previous generations.Not sure I'll be ready to spend that much.

How are you liking the headers? I had great luck with a ported throttle body and intake manifold on my C7 as well. Paragon just dyno tested the Attack Blue air filter for +6 whp; AFE was right behind it at +5.

I sold my last C7, in anticipation of getting a C8 and building a blower system. Once I saw one up close, I realized it was going to be an expensive project with a VERY limited demand. I figured, right off the bat, that it would require a jackshaft to transfer the belt drive to the other end of the engine. Then it would "probably" require an air to water type intercooler system, All this adds up to $$$. Then tuning, if and when it becomes available, will be ridiculously expensive. Maybe $3000 or so per unit? I don't see me selling hundreds of these a year.
I am, however, going to have a go at it on my own car. It'll be a while though. I'm not in any hurry like I was with C7.

I think you had your C7 kit already on the market before my 2014 was even built...

I'd be lying if I said I noticed much seat of the pants improvement. The quality and fit are top shelf, as expected.
Make a little more noise, but I'd like more.
I intended to get some good Dragy before and after numbers, but I did not get clean numbers before, so that was out the window.

How do you like the headers? Much of a sound difference? Feel any quicker?

I have them, but I won't put them on until spring. And I will do a before and after dyno to make sure it's comparable to their dyno results.

Thanks
