So now that I've decied to convert my LT1 front end to an LS1 front end, I've been thinking a lot about making it a front breather.

Why don't more people do it? Seems like a little trimming of the Impact foam and bumper beam and you could duct air directly to the radiator instead of scooping it from the bottom. The openings in the bumper are about 70 sq inches combined. Seems like it would be plenty for the radiator.

Seems like it would be a more efficient design and create less lift at speed.

For those who have done it, how does it preform?

Measuring the opening of my LT1 front end, I figure you had a little less than 140 sq inches of opening with your ORR Camaro....about double what I would have. I think the LS1 bumper cover would do well with the center removed as a front breather with about 240 sq inches of area. A tubular bumper would probably be a must though and the looks would suffer.

I don't want to mess with that right now, maybe someday. Thanks Alan for taking the time to help clear that up. It's something I've always wondered about.

Before I put aero on my AI Camaro, I ran a front breather with no cooling issues at all. My car was a street/track car for a short while.

Can you give me more information about your set up?
