mine has been off for about 2 years...run the same without it as for temps it is at 190-195 in stop and go traffic being 80* out...
I took it off because I figured it will help with aero...
I do has the front holes open where you have the sux2bu ram air so I am sure that might help some...maybe not though as mine stays the same in stop and go traffic...
I cut mine at the horns and dropped the whole lower radiator support...came to 18lbs and them I added 1.5lbs worth of aluminum brackets to hold the radiator in place

anyone else.
i know the lt1 has more front opening then the ls1 front end.
chris so you get air thu the sides of the grill opening, wouldn't your duct still block the rad. how close is it to the rad.
i guess i could always switch to your setup

An air dam restricts the amount of air flowing under the car. The more air that flows under the car, the more resistance generated from hitting the underbody components. It also prevents the front from compressing under the nose, helping to prevent lift.
Popular belief would tell you that it's just protruding into the airstream and must cause drag, but that is definitely not the case.

There alot of work to get tham to fit right. We ran them in the ALMS on our GT cars...a real pain. I'm gonna make one for the back of the car to clean the air up coming off the rear bumper in a week or so. I'll test it at the track to see the difference.

chris, what did you do about this
looking at what plastic i can remove, i know guys remove everything, but i dont what **** flapping around doing the burnout like i see on some super gutted cars 
i might runa little bar of alum to each side of the lower bumper holes, and 1-2 to the front. but any of you camaro guys cutting the bottem of the bumper cover off, there thouse 3 holes went into the bumper support. i think it would help get more air to the rad. with the plasitcs gone. and maybe make it more stiff, without that heavy part sagging down there.
cut this out

^ yes with your ram air setup I would remove that portion but I would just narrow it to the width of the radiator and then box the front end up with some .040 thick aluminum or abs plastic sheet...it will help with aero...I plan on doing mine in the next 2 weeks or so
fenders are removed, pulled my speakers, pulled air bag & bracket, pulled ebrake handle assembly, with my light weight battery up front I am down to 58lbs loss...door bars will be another 16lbs or so...

ya that is about the same width as the rad.
were are you talking about running the alum/abs too. on the flat sides were the lower underside plastic were. ya i would like to do somthing like that, only have 3 days, gota get the driveline back in 1st. haha
this is what i might do with some little alum. bar stock like posted in my build thread

yeah exactly and I am going to put a deflector on the back side of the radiator that is angled downward about half way to the engine to guide the air under the car so it doesn't get trapped and cause drag by slamming directly into the engine...also do the same in the rear so the rear bumper doesn't act like a parachute with the catback & bumper support gone...
I am not going to use alumin strips since I hope the sheets will tie it in enough...it will probably add 6-8lbs with the whole front and rear done but I am hoping the aero advantage will out weight that
