Halltech Beehive Ram Air Induction
2006 Z06. I've had the Beehive and shrould for some time. Works great. My question is has anyone else got this intake system and shrould and cut out the two cut out areas at the base of the radiator shrould for a Ram Air effect as they recommend? I hate to cut them out and find out it's not worth it. My car runs mid 11's stock is not a daily driver either. Any replies appreciated.

I have it on my car non-z06 but I left it alone and didn't do the cut ram-air feature. It CAN'T make that much of a difference for something that drastic to cut up the car. I know you can buy a new shrowd -- but why for 2hp maybe?

I cut & added a Vette-Air. Works great.
How's the air getting into the air box that the shroud creates? With mid 11's it's coming from somewhere, but where? Through the small areas where the shroud doesn't seal that well?

Did the cut outs with mine (Halltech KB and Beehive)and just returned it back to stock. I don't think the cut outs were worth it IMO. Plus it's a real PITA to replace that radiator shroud if you decide to go back to stock.

However, I decided for overall performance I prefered the stock LS3 intake. So, I modified the Beehive shroud to fit the stock intake and left the cold air cut outs open. The purpose of the cold air cut outs is to reduce the IAT's and prevent the tiiming from being pulled back resulting in hp lose.
I feel this current set up gives me the best overall performance.
Since you have a Z06 with the open air duct on the top, I would not open up the bottom of the shroud. I would leave it stock because you should be getting plenty of air from the duct. It sounds like your car is running just fine!
Halltech recommends opening up the bottom of the shroud for the base corvettes because they do not have an air duct like the Z06.
