Stock Dyno results
Here are the dyno results for my stock RT. 2500 miles on the car.
I did 4 pulls all with the #17 fuse pulled and the car in 3rd gear.
The first 2 where as I pulled it in the shop with all stock equipment in place.
the best of the first 2
SAE Max Power 278.1 @ 5100
SAE Max torque 318.2 @between 4000 and 4400(it's not marked on my sheet)
For runs 3&4 I unhooked the intake from the air box and left the hose unfiltered.
ready for this!
SAE Max Power 296.5 @ 5200
SAE Max torque 327.9 @between 4000 and 4400(it's not marked on my sheet)
It would appear that a free flowing intake is well worth it.
My brother dynoed his ls1 right after I got through. He gained only 5 horsepower by opening his air box to eliminate the filter. His does have the ram-air box though.
Air- fuel ratio
Mine read 11.7 to 12 from 4100 through 5200 rpm on all runs. That means there is power to be made by leaning the mixture (programmer)
One more thing -This motor sounded awesome with the intake elbow unhooked from the airbox!

RE: Stock Dyno results
Great post and thanks for the info. It would seem the HP claims made by Air intake vendors have some sort of validity as they fall somewhere in the middle of stock and unfiltered.
As for the LS1, that engine was already pretty efficient from the factory. I owned a 2000 Camaro SS that made 315 RWHP with 1000 miles on the clock. The specs on the car had it making 305 at the ENGINE... They did that so Corvette owners would feel like they were getting something more special in their cars than lowly Camaro owners when in many cases the F-body cars dynoed better!

Illy,
If only we had a fraction of the aftermarket parts available for the Hemi as there are for the LS1, Hogg Heaven
I too owned an LS1, 2002 Z28. I traded it in on the Magnum. The Camaro is a fun car but I like comfort also.
I would make this trade again in a second.

Hmm about the air fuel ratio, I was thinking that the computer would have automatically adjust for the air/fuel change. I guess they arent as smart as I thought.
Now for the lighter side. Run a tube from the intake, in place of the filter box, to the inside of the cabin. Point the opening of the hose near the output of the AC. Run it on MAX. This way you get lots of cold air and hear all the intake so that it is not tainted by the tire spinning hahhah.
