You name the track and what kind of race and Big Red, the door-slammer ’69 Camaro complete with a VIN and steel body parts, has done it. Most recently it ran 266.2 mph in the Mohave Mile! The news is out, and has been for a few days, but only at Chevy High Performance will you find these exclusive photos and notes taken from behind the scenes.
Here’s how it happened.
Super cowl induction; like that fancy new hoodscoop and its uniquely rounded shape that parallels the windshield.
That new hoodscoop was designed from data obtained during wind tunnel testing last year.
They went with the 555ci engine armed with a ProCharger F-3A set at 23 psi of boost on methanol, a blow-through experimental carb from The Carb Shop (work done by Vrbancic Brothers and The Carb Shop), and an old MSD distributor that Dave Ward made for custom mechanical advance.
Removed all the electronics in preparation for Bonneville this year. The class they are going to run in (with an attainable record) does allow electronics. All manual.
Traction is very tricky at Bonneville so the smaller engine is designed to focus more on horsepower instead of torque. Hence, the smaller 555 with 1,960 horsepower.
Didn’t expect to run a 266.2 mph out of the box. The engine combo worked and the hoodscoop aero was probably the key to the jump from 253.6 to 266.2.
The 555ci engine combination made 1,960 hp and 1,450 lb-ft at 7,300 rpm.
Wind tunnel testing also proved that wide tires in front are not an aero problem, so they didn’t run the typical narrower front wheels and tires. They went with Hoosier 315/30R18 fronts and 345/35R18 rears.
Obviously, it takes a lot more than wide rubber to slow Big Red down!
