exactly because in the end the air will only get sucked into the motor when and as long as the TB is open or wide open and only a certain amount of air can get thru that intake tract regardless
That intake actually did have some turbulence issues. I helped develop the ZO6 filter media along side Donaldson.. Our C6 Z06 on the dyno all day. The higher flowing ZR1 filter saw a huge gain over the Z06 filter by 2 to 3 RWHP. In the end, we distributed 100 of the ZR1 filters for Donaldson, until GM stepped in and slammed the marketing door shut on our collaberation.
Turbulence "at the MAF read area" is all you need be concerned about. I am referring to surging at very low throttle position. You are correct in assuming that at max rpm the airflow is measured only be the MAF sensor since it is in open loop. During closed loop, the MAF cannot properly read the air mass when the flow is swirling around the wire pickup. That is my only reference.
We started selling a honeycomb screen 1/8 cell for the C6 Z06 due to the screen being removed by GM in the hopes of picking up another couple HP. As long as you kept the stock intake onboard, with the stock MAF and factory tune, it all came together and no lean codes for underreported air.
Once the VR or other intakes were introduced, the lean codes started appearing, even with our Venom first gen. We add the honeycomb to all Venom orders, and have done so for many years.
Good information. Thanks,.

Halltech Ram Air without the turbulence: Years ago, Halltech did this to our C6Z06. It was not easy, but it was effective. Ambient IATs within a block. Our C6 Killer Bee and Super Bee intakes both come with our Beehive. Check out the filter in this pic. It is getting inundated with cold ambient air. At 86F your sweet High Octane tables start to take a hit from the IAT table. Add some knock count to that and you will start shifting from High Octane to Low Octane
tables. Want to keep your High Octane tables without sacrificing low pedal driving?
I've had Halltech's complete carbon fiber cold air induction system on my car the past six/seven years. During that time it has preformed flawlessly.
Hope Jim finds the mold.

no thank you for the clarification i always appreciate the honesty also im using your Haltech intake just need to get my hands on the heatshield
