Performance wise it makes 440/441 to the rear tire. I was really happy with those numbers being how I have never even had a valve cover off the engine since I installed it fresh from the crate. The blower is set-up to 6psi right now. The car still idles like stock and you'd never know there was a blower on it until you get into it hard. It still pulls down 29mpg on the highway. My goal with this car was to be dead nuts reliable and drive as much like a factory car as possible.
This was the engine bay before I put on the Magnacharger
And this is what it looks like now. It was prettier before but I think all the added power makes it worth it...lol
Here's the 9" after I assembled it and before going under the car.

Very nice! I can just imagine all the hours you've wrenched on that thing. Worth it in the end though.

Re: December COTM **WINNER**
I've never seen your car on here before my oh my how pretty it is. Hands down one of the best on the boards. The customization looks nearly factory making it perfect!
I'm a big fan of the wheels as well. Job well done.
Can we get some high rez pictures for screen saver purposes?

Re: December COTM **WINNER**
Thank you very much guys! I've never tried to get it into a magazine. In my mind it's not ready for a mag yet...there are still things I want to do to the car first. This car has been an evolving project for me almost since day one 17+ years ago...and it continues to be. It's taken this long to get it where it is because I never had a big budget to work with and had to scrimp and save to buy some of the big ticket items. The thing i am most proud of is that I have did it all myself, except for mounting the tires on the wheels...lol

Re: December COTM **WINNER**
I can't speak for anyone else, but so often I look at my car, or get in it, or drive it and say to myself "if only..." or "I can't wait to..." Looking at your car, I can't say that. You have actually built a 2013 3rd Gen Camaro. If it rolled off the assembly line TODAY that is what we could all see the SS version looking like. UTTERLY FLAWLESS. Except for this little ramble, I am speechless...
Re: December COTM **WINNER**
This IROC is definitely my favorite Camaro and also the one I voted for. This particular F-body is the only one I've seen that I like with the side moldings removed. My guess would be that white colored cars can pull this off better than other colors. At any rate, congrats on a very well deserved win!
