Does a track day Corvette Callaway Z06 SC757 w/HD Cooling System really work in 110ºF+ conditions?

www.callawaycars.com - Does a track day Corvette Callaway Z06 SC757 w/HD Cooling System really work in 110ºF+ conditions? Find out at Willow Springs International Raceway in Rosamond CA.
HD Cooling System (Level 2) explained, and put to the test on a recently-built 25th Anniversary Edition, featuring the Champion Package and several competition options.
Let Callaway resolve your Z06's overheating issues.
While this test car was a 2016 7-speed manual, the system also performs well with 8-speed GM 8L90 automatic-equipped Z06's. Visit our website below to review engineering test reports of multiple configuration cars and environments.
Watch this video to get a walk-around overview of the Callaway SC757 featuring the GenThree Supercharger System w/ HD Cooling (Level 2) and other features of the 25th Anniversary Edition explained by Pete Callaway and tested at Willow Springs International Raceway during the grueling summer heat. In-car video and instrumented temperature data shown in a full 25-minute session at a recent Speed Ventures track day at "Big Willow". Callaway was there for engineering and customer support. Corvette's Performance Data Recorder (PDR) was also utilized to capture video and vehicle health data (shown at end of session during the cool-down lap).
Observe the trends of the engine coolant temp, oil temp, inlet air temp (IAT), manifold air temp (MAT) and transmission temp leaving the heat-soaked pits, and then stabilizing before consistent lapping. Note: MAT is a calculated value based on several temperature inputs to accurately predict charge air temperature as it exits the supercharger's intercoolers and enters the combustion chambers. IAT is measured at the mass air flow (MAF) sensor located just after the air filter. Ambient temperature as reported from the vehicle. Track temp measured in the pits at 148ºF.
It’s common knowledge that the C7 Corvette Z06 cooling system can be overtaxed during aggressive driving or on-track use. The result is power loss as the stock intercooler system isn’t capable of removing enough heat from the compressed inlet air. Plus, excessive oil temperature can have an adverse effect on engine oil lubrication properties, resulting in serious damage to engine components.
Callaway HD Cooling Systems were developed in a collaborative effort with sister company, Callaway Competition of Leingarten, Germany, and Entwicklungs Partner, Tikt Performance of Stephanskirchen, Germany. We turned to Callaway’s 25 years of motorsports success, combined with Tikt’s road car product development and advanced manufacturing capabilities, to support the introduction of a proper cooling system solution.
While HD Cooling Systems work best with the Callaway GenThree(™) supercharger system, they also perform well with otherwise stock Z06 Corvettes. Now you can focus on improving your lap times without fearing the uncontrolled rise of the temperature gauges and the dreaded “limp mode”. In fact, during testing, Callaway engineers reported a significant improvement in overall performance as power was not lost by running at higher temperatures for extended periods.

Great driving and outstanding engineering feet, with the A/C blowing cold!! 🥶

[@MrTrglass]

That’s was something serious driving in the heat my friend! And seeing the coolant and oil stabilize in 100+ ambient at that pace….wow!

[@PeteCallawayCars]

Thanks Mr.T! That was my first real open lapping session there. And in a car with the aero, lots to work up to! Used pilot super sports, could have used a few less psi, but the point here is to provide a consistent testing bed, driven hard, but not necessarily setting any lap records… I also try to be a little more careful when it’s not my car ;) but really nice to not have to worry about temps and just focus on driving. This car also has the uniball suspension setup with bumpsteer and camber kits- running about -3.0°f/-2.5°r, so the tire wear is near perfect. No more shredded shoulders after 1 session. And the car is really planted without feeling harsh on the street. Cheers 👍🏼

This was entertaining to watch… way to go, Pete 🚗💨

Nice job Pete. If you're ever in my area please know you're more than welcome to take my 2017 Callaway 25th Special Anniversary Z06 out on any track you'd like. Besides all the excellent cooling management changes Callaway has made, your short throw shifter is one of the best, if not the best, shifter I've ever had in the many manuals I've own over the years! Great video and day at the track...

[@PeteCallawayCars]

Thanks Richard, that's a very kind offer! Look forward to meeting you someday. Glad you are happy with the car; agree with you on the shifter- makes all the difference. Save the manuals!

Austin( Speed Phenom) has a great KZbin channel! Check out His interview on the C8 Z-O6! I hope that You crack the ECM on the base C8. It would be great to see what a cam change would do!

Add one MORE COOLER...OIL... Add one MORE COOLER ..water..... charge coolers ok....trans cooler needed , too...?

[@petervogwill6499]

Driver needs cooler (ac)...BTU transfer is high...Calc loads on HOT DAY WILL COOK EVERY LIQ SYSTEM AT RACE PACE....LOL
