Halltech Stinger-R installation thought
Something just occurred to me regarding it. It’s been around a year since I installed it and once in a while I still see comments regarding how guys are so pleased with it. I too have very positive things to say, although In the back of my mind I have always had a nagging question regarding its design. Anytime I see comments, I haven’t seen one about problems with its installation. I can’t be the only guy in the world with the problem I ran into.
I Just couldn’t make the larger airbridge fit. No matter what I did, repositioning in every conceivable way, even removing the hood liner for more clearance. I just couldn’t get the hood closed properly without the air bridge making the hood bulge. I ended up using the stock airbridge with the stinger filter. I also did the cool air mod that grabs outside cool air. My car is lowered, so I was just thinking if that might have had something to do with it. Maybe my thinking is flawed, but could lowering bring the car closer to the engine, thus the problem? There must be guys that have lowered cars and the same intake, but as I said before, no comments about clearance problems. Does anyone think this is a possible explanation?

Steve,
It could be that your particular Halltech airbridge is out-of-spec. and that this is probably a rarity, given the absence of complaints.
Another possible reason is that one or more components of a number of assemblies in the engine bay are on the high side of their dimensional tolerance. It's not enough to cause any issues with stock components, but a larger airbridge could very well cause a fit problem. I once worked for a company that employed a guy who measures a part, designed a mating hole to a standard drill/reamer size, and left it at that. If he had checked the part tolerance, he would have found that the part he measured was on the low side. Once a part with an O.D. on the high side was issued to an assembler, that person found that it just would not fit into the hole.
It could be that Jim Hall measured aC5's hood clearance and designed the airbridge based upon those measurements. You C5 comes along with the stackup on the high side and viola - an interference fit!

Interestingly, it actually seemed like there was MORE power with the smaller stock bridge, which I attribute to the velocity factor, like when the air comes in through the Warhead, then is compressed into the smaller stock bridge. But, I like the much deeper sound of the Halltech bridge so I put it back in, and just live with the way it's pressing on the hoodliner. I just hope that the pressure isn't slowly ruining my hoodliner.

Mine rubs the hoodliner, but that's about it, at first, it did press on the hood and make it buldge..took quite a bit of adjustment and messing around with it to get it to finally sit right. I don't care about it pressing against the hoodliner....you can barely tell it does, it's almost not noticable.
I think Dave is in the ballpark... just like all LS1 motors are not created equal from the factory..some have a bit more HP and a bit less..same thing with the body/hood of the car.... and same thing with the stinger intake itself..it's possible there is a slight variance in the tolerance or something.

Same issue here...you are not alone
I went back to the stock airbridge as well, the stinger airbridge collapsed when I tightened it and I had an air leak that took me a week to track down...
Other than that, I'm very happy with it...
Peace

I have a new Halltech Stinger system and it depressed my original hood liner a little. I have sinced replaced the hood liner with a new one that is thicker. It again depresses a little but the hood shuts fine. The depression does not bother me as it is so small. I like the look of the system to much since I show. I have not had the opportunity yet to hear or feel any difference since the install was just done and just put insurance back on to drive from storage. You might talk to Jim at Halltech. He is a great helpful guy.

Same here! A little depression on the hood liner, other than that it's a-o-k! I did the cold air mod also, it stopped my engine light from going on and off. I'm thinking of switching to a BBK intake cause it would match my painted engine covers better. I'd still use the Warhead filter though, the BBK filter is smaller.

The only way to know for sure would be to replace parts until the problem is solved, but I'd say it is not worth the effort.

Anyway, I already had a depression in the hood liner from the stock airbridge, thus my thinking a bigger one wouldn’t fit. So it must be an issue of the “one time occurance” on the car. My car must have an irregularity in the radiator shroud or someplace else making the airbridge taller than most other Vetts.
I really like 02gt350s coment, because that means I’m better off with the stock one.
“it actually seemed like there was MORE power with the smaller stock bridge, which I attribute to the velocity factor, like when the air comes in through the Warhead, then is compressed into the smaller stock bridge.”
And Dave, how did you know my car is incriible?
