As they say, records are made to be broken, and this has been the case for the sixth-gen Camaro ZL1. We have had numerous reports on different cars running in the high 9s including Miguel Pena who went a 9.646 et at 144.86mph. Right as we were getting ready to break with a news article on Mr. Pena, another competitor emerged. Michael Talley showed up at Memphis International Raceway and reset the record with a quarter-mile pass of 9.570 e.t. at a 143.22 mph. To our knowledge, this is the quickest stock blower ZL1 pass that we know of but how long will the record stand? After all, these cars have crazy potential, and they keep going faster as parts become available.
Talley’s ZL1 is a 2018 model which was equipped with a 650 horsepower LT4 and a 10-speed automatic transmission. For the engine modifications, Talley opted for a Gwatney Performance Innovations (GPI) custom cam and head combination to make sure the factory blower has no restrictions while moving air from the cylinders to the exhaust. The factory blower was used with a new lower pulley, Joker Performance ported blower snout, methanol injection, and a Nitrous Express (NX) blower lid without nitrous. The lower pulley bumped up the Camaro from 9-pounds of boost to 14-pounds. Other bolt-on modifications include a set of Kooks Headers tied to a complete Corsa Performance exhaust system, Rotofab intake, dual meth injection, and a Katech 103mm throttle body.
The fuel system on the Camaro remains stock, but the car was tuned on VP Racing C16 Fuel. Ryan Stevens from Gwatney Performance Innovations is responsible for all of the tunning while Greg Taylor handled wrenching duties. All of the bolt-on modifications and tunning have netted the ZL1 an impressive 750 horsepower and 720lb-ft of torque. The only other changes that have been made are the addition of a Carlisle Racing 15-inch rear wheel conversion and a set of 15×10-inch Weld wheels with Mickey Thompson drag radials. The conversion and tire selection has allowed the Camaro to run a best of 1.393 sixty-foot time.
The rumor on the street is that the car has more in it, although we will have to wait and see.
