How much power with blower?
Im trying to figure out how much boost or how much power a stock motor C7 can make, without swapping out the cam, and no meth however with the following mods:
- centrifugal blower
- headers
- heads
- tune

On our 2015 A8 we made 701 RWHP on a Dyna Pac Dyno and about 668 our Mustang Dyno with the following:
ECS Kit no restrictor on 11#'s
Alcky control meth kit
ARH 1 7/8's w/Stock NPP Mufflers
This was good enough to get us 10.3's @ 135+

high. You may have trouble down the road. 570 rwhp is about the number these do on a stock car.
I had a higher number too, but needed to pull back some.
Hope it works for you!

NO ONE that is reputable will claim that without additional fueling. Do some research and make sure you look past a post titile/heading. Some might be using a crank number versus rear wheel number also. If it doesnt end up being a fuel delivery related limit it ends up being a fuel quality one when using nothing but the stock fuel system and pump gas.

Is it being done sure, but you have to decide if it's worth betting a $10k motor on
On the CTS V kits, I run an 8 jet system that puts one per cylinder with check valves for even distribution. Even that is more for cooling and octane but allowing an even distribution seeing about 25-35hp increase on a 600ish whp car. These cars are right around the corner from having more fueling options if you're not doing a cam to over drive the OEM pump now so be patient. Off my soap box now

I agree with Ben, I love meth and have used it in a bunch of different boost setups but it's being used as a bandaid right now on most high powered setups. Like Ben said the zo6 mechanical fuel pump should be released any time. Should bolt right in just remove the intake manifold. I'm sure the z06 will have larger injectors too along with larger lines ( be a nice kit to get, injectors, fuel pump, larger lines) increased fuel pressure will help too.

However, supplementing it with a single nozzle for fuel especially on a DI motor and praying it evenly distributes into 8 cylinders after seeing the OEM LT1 manifold is a gamble I'm not willing to take.
very true. I think meth should be direct injection
ECS found that on a high hp c6 at 1200 hp the cyl variance was 300
meth wasn't making the turn and the rear cyl were much richer
I think tapping the intake and running a small meth nozzle in each port will atomize it better and dramatically help the distribution problem

Depends on how much meth you're spraying. Using it to up the power from 600 to 700 rwhp from a single nozzle is fine and VERY well proven to work for many years now. It is fully atomized and distributes evenly.
Once people are going to dual nozzles and really cranking it up then the problems begin. We have tested this many times with EGT sensors for proof.
