We just baselined a 2010 Camaro with 342 hp. Only 100 miles. Has Edelbrock shorties and Magna Flo Exhaust. We are now installing an Edelbrock Supercharger and custom Comp cam. I'll post the dyno results after the install. The supercharger is a nice piece as are the install instructions. I'm at home and can't remember the cam specs. Our dyno is a DynoCom.

342hp seems low for 2010. I thought they usually put down between 360-380rwhp stock.

 

GMHTP did an install in their last issue I think the horsepower was about the same on a stock ls3

 

The A/F was 11.5 at full throttle. I can't believe that it would be so rich considering it also has Edelbrock shorties and Magna Flow cat back. We didn't bother to tune it as we are doing the super charger install and cam swap now. I got the super charger installed to-day and tore the front off the motor. Just waiting for the cam kit now.

pics or ban

 

Not gonna try an LS9 cam with that? I've heard it has GREAT street manners, but SCREAMS up top when you open it up.

 

And!!!!!???????

 

Just got the cam to-day. Monday I'll install,degree it then order the pushrods.

That Edelbrock supercharger is a great kit. GREAT instructions.
Easy install. Tuffest part is drilling for a dowel pin in crank so the balancer won't spin.

great. post some pics too if you can. gonna dyno it befor the cam?

 

Ok, what is the deal, did you break it on the dyno?

 

342 is an outlier. Assuming the shorties and exhaust are doing nothing HP wise, it's too high for a L99, too low for an LS3... but with dynos you never know.
