[QUOTE=JLSuperfly;1607815063]Just how many hp is enough?

If some is good
and more is better
than too much
is just enough!

Goat 2 Vette

I have an ECS on my car. Kooks long tube headers, catless x pipe and billy boat fusion axel back. Soler 93mm throttle body, soler throttle controller. Those 2 alone will make your car so much more fun to drive. You can't go bigger on a centri blower, you need an adapter plate and with that on, the TB won't fit.. Ask me how I know.
Your not going to break the car with that blower. Watch some Late model race craft videos. They use Ecs all the time and tell you its not going to break. My car makes about 570 at the rear wheels, zero problems. The only problem is, if you step on it, your going to do triple digits in seconds.. Unless you track it, the only time you can really step on it is on entrance ramps.
Also, your going to lose your *** if you ever trade it in. Possibly even selling it yourself. Mine already had the blower on it. I ended up getting it for the same price as one that was stock.
If your thinking about selling your car in a few years, don't do anything. Maybe a shifter, throttle body, throttle controller and call it a day.

I didn't see anyone mention Atomic Intake Manifold.
Larger Throttle bodies do seem to make a difference. 100mm +
Of course you free up exhaust with Headers and Mid pipe.
A little more on top with E85 flex fuel unit.
Don't expect it all to work without getting it tuned.
should get you to 460 or higher.
This is me just spending hours watching Dyno tune videos with no real experience. - yet.
so grain of salt on this post.

Make sure you baseline before you start.

TOM, I'ts been 3 months since your original Post. Any updates? What parts did you get and what power did you make?

Good question. In some ways my LS3 c6 coupe with wider wheels and tires was more fun to drive than my c7z.
