We do intakes right. With 12 years experience in CAD designed induction systems for the Corvette, look at who runs our intakes on our website. Many GM Chevy dealers, Katech Engine Development, and the Halltech Killer Bee is the mule used on ALL Katech built motors in their Superflow dyno cell.
You have to ask yourself why the company (Katech) would put their name next to Halltech's intakes.
Our most recent Super Bee CF112 intake just dynoed at +33 RWHP/26 lb-ft on a brand new 2010 Z06 straight off the carrier. MAF re-calibration is a must on this intake, but other than that the factory tune was left intact. Those numbers set a record for bolt on mods, and even compare with cams.
One last bragging thing. Halltech's first generation Killer Bee just helped Livernois Motorsports built 630 RWHP NA Z06 run 9.95@139. That is another record. Stock bottom end motor, with a cam and bolt ons.
