The October 2026 issue of RPM Magazine is loaded with serious street and strip horsepower, from old-school muscle to modern boosted performance. Leading the charge is Mark Mannor’s “Spoolius Caesar,” a stunning 1970 Chevelle that has evolved into an 8-second, twin-turbo big-block drag-and-drive machine while retaining its classic muscle-car roots.

Also inside, “Blue, Boosted & Bad!” takes a look at a modern Mustang GT built to chase eight-second time slips without giving up its street manners, while “Orange Juic’d” serves up Nitro Dave Vasser’s Hugger Orange Camaro with a healthy dose of supercharged power. Rounding out the feature lineup is “Horsepower Revisited,” bringing back Gene Wilson’s incredible 2,000-horsepower AWD street/strip GT-R from the RPM archives.

Add in RPM Video Extras, Editor’s Pix, detailed tech, incredible photography and plenty of extreme horsepower, and the October issue delivers the mix of wild street machines and serious race cars RPM readers have come to expect.
