Diamond's Customer Showcase
Kenny Duttweiler - Speed Demon
“We use Diamond pistons with crown and skirt coatings and tool steel coated pins. They’ve performed better than anything we’ve tried in the past. Diamond’s quality is excellent and their service outstanding.”
The “Speed Demon” is powered by a “Hellfire” 347-cubic inch small block engine using two 82mm Precision Turbochargers burning alcohol to challenge Al Teague’s long-standing 406.321 mph FIA record. The unique “Hellfire” powerplant is designed and constructed by Duttweiler.
The 462-mph exit speed, clocked after the end of the flying mile and not valid for FIA records, exceeded the Burkland family’s 450-mph exit recorded on September 20, 2000, (using two supercharged nitro-burning Donovan Chryslers), and each intermediate time is now the fastest speed ever clocked by a wheel-driven, automotive-engined machine.
