Believe it or not, John laid down 270 passes with this engine before losing a head gasket. He said a conservative tune-up and meticulous engine construction courtesy of Sean Hyland Motorsport are the keys to its durability. Though the $10,000 custom Accufab intake certainly stands out atop the engine, the engine is short on other unobtanium parts. It runs ported stock heads (fitted with large 38mm intake and 31mm exhaust valves), reground stock cams, motorcycle valve-springs (for max high-rpm durability), Manley rods, and JE pistons. John says it even survived an 11,000-plus-rpm over-rev courtesy of a blown tranny. Try that with a pushrod motor.

Inside, John’s racer is all business. Sheetmetal is everywhere, and the shifter poking up controls a Performance Automatic Powerglide transmission fitted with a 6,500-stall Neal Chance torque converter. Also in the cockpit are a host of Auto Meter gauges and an Auto Meter data-logging system, which is essential for examining what went right or wrong during a pass.

This full-tube chassis racer features a fiberglass hood, fiberglass fenders, and a fiberglass trunk lid. These slimming body panels help trim the package down to an anorexic 2,265 pounds. The flyweight chassis rides on Lamb struts up front and Koni shocks in back. Weld wheels hold the rubber at all four corners, and a four-link and anti-roll bar keep the rearend planted.

If you follow modular Mustang racing, you know the name John Mihovetz. John is the proprietor of Accufab Racing, which whittles out throttle bodies, starters, clutch quadrants, and other goodies out of billet aluminum. You’ve no doubt seen his polished throttle bodies on numerous Mustangs in this magazine. But John is better known for pushing the envelope of 4.6 performance with his ’93 Mustang LX coupe equipped with a Vortech-supercharged Cobra engine.

This car ran low eights, made it in all the magazines, and generally did a good job getting attention for John and his sponsors. However, the car was “just tired,” as John says. Both physically and image-wise, the Fox car was done. As circumstance would have it, Coast High Performance had a bright-red, tube-chassis ’96 Mustang without a place to race. So John fused his reliable engine combination with the 25.1C chassis and shortly turned the modular world on its ear with a 7.99 blast at 170 mph.

Horse Sense: Reliably cranking 29 pounds of boost out of a T-Trim Vortech is no easy task. John Mihovetz is able to do so using a custom billet bracket arrangement, a cog-drive system, and a 55mm Kevlar cog belt. John built the system himself, and it delivered 250 passes without a belt failure. If you want one for your V-1 series Vortech or Paxton Novi 2000, Accufab Racing [(909) 930-1754] sells the kit for $2,500.
