What Intake system does Katech use on their engine dyno when testing the LS3 or LS7? Halltech's Killer Bee MF103 or the MF108. The differences are minimal between the two, with the MF103 sporting 104.5mm MAF read area, and the MF107 allowing a MAF read area of 108mm.
Bigger is not always better, but when adding cams, headers, head work, and tuning, the MF108 provides more headroom for MAF curve tuning. Some tuners scale the MAF curve to their preferred a/f ratio, and the MF108 shines with that type of tuning.
Our Intake has been sold to engine builders, tuners, and retail customers that love working on their own cars. The Halltech Super Bee Filter is used on all of our C5 and C6 intakes and flows enough air to put the competition to bed wet. I designed the inlet with a full radius velocity stack that promotes fully
developed laminar flow at the MAF sensor for perfect throttle response. Our Williams Performance connector hose or Katech 103 connector hose are optional, but not more expensive than our stock silicone hose.
MF103: No MAF curve scaling required
MF108: MAF curve scaling needed. Having said that, I tuned a C6Z that had the MSD intake manifold onboard, and our C6Z MF108. The MAF tables were perfect without any MAF scaling, and LTFTs were +or- 2% from top to bottom.
