Is 330 RWHP and high heat outside the straw that breaks the camels back? The LT5 just has that much vacuum?

squeeze the factory duct when it's hot and see how easy it is to collapse, it's terrible. I forgot how bad it is since I've had an upgraded one on mine for nearly the entire time i've owned it.

Next time you go to the dyno take the accordion off, Let your beast breath.

I bought the last one that mark coplan had years ago at BG. Mark Haibeck, sells a solution that I would look at. Both keep the factory appearance and provide a more robust duct to keep it from collapsing. Coplan used a piece of aluminum inside the duct to keep it collapsing. Haibeck uses hoops. http://www.zr1specialist.com/HAT%20W...ucts/hoops.htm that's a link for Habieck's one. Back when coffee cans were metal some people used those, cut up, to fit.

Jerry's makes a new one too.

Yep! Been so long ago. I fashioned a liner out of sheet aluminum (smoooooth!) and pop-rivets. That solved my collapsing accordion - was choking out at 5500 rpm. No more!

Didn't realized jerry made one. I'll add that to the mental list

I didn't even think of that....Marc has done maintenance on my car a few times. I'll check tonight, I may already have some in there.
