The most important consideration for any track-day special is not horsepower, suspension setup, brakes or tries. Ask any Formula One team, Le Mans racer or local SCCA guru; the number one consideration is cooling. If the car doesn’t stay cool, the car won’t run. You can have a million horsepower, but does no good if you are sitting in the pits waiting for your engine to cool.
General Motors understands this well, so for its new track-focused Camaro Z/28 it has taken every piece of the car to the drawing board to help improve cooling and overall performance. One of the biggest changes to the car ended up being the smallest; the Flowtie.
During wind tunnel testing, engineers noticed that the shining gold bowtie on the grille was forcing lots of air away from the radiator. Richard Quinn, one of the Powertrain Cooling Development engineers, decided to take the bowtie off and he cut out the gold insert, leaving just the chrome outline. The results spoke for themselves with a 3-cubic-meter increase in airflow every minute. The net result of that was a 2-degree temperature decrease.
The newly christened Flowtie is now standard on every Z/28. If you have ever hacked at your car with a grinder, you are now justified.
If that wasn’t enough proof that Chevy believes the Z/28 is a true track machine, think about this. General Motors will provide you full warranty service even if you cane your Camaro at the local track. There are essentially no other manufacturers that will cover your engine explosion in turn 6 at VIR.
It is at this point where I believe GM would “drop the mic” and walk off dramatically.
