Over the course of the 2011 racing season, the West coast-based H&H Racing team, with driver Kelly Henry, completely revamped the combination in their ’91 Ford Mustang in order to conform to the regulations for the West Coast Hot Rod Association’s X275 category. Gone was the 454 cubic inch big block with a Vortech YSi-Trim supercharger that had propelled the car into the high eight’s, replaced with an all-new 525-inch big block fed by Vortech’s latest unit – the V28-123 supercharger paired with a CDS supercharger driver from Chris Alston’s Chassisworks.

The H&H team had kept the dyno numbers on their new combinations under wraps – rumored to be in the neighborhood of 2,000 horses at 35 psi – opting to let the numbers on the racetrack do the talking in their debut.

Well, that debut came at the recent WCHRA Chris Alston’s Chassisworks “Shootout at Sundown” held at the Famoso Raceway in Bakersfield, California, where Henry and the H&H team tackled a new objective of controlling their horsepower rather than trying to cope with not enough of it. And on just their fifth pass, netted a 5.69 eighth-mile time (minutely quicker than their previous combination) at just 125 MPH.

Two weeks later, they returned to Famoso to test some things on the eighth-mile, beginning with a great 5.28 at 145 MPH, coasting through the boards to an 8.35 at just 135. With the car turned around and cooled off, a couple degrees of timing were added, resulting in an even quicker 5.21 at 147 to the eighth and another off-the-throttle 8.36 at 128 to the quarter-mile.

At last weekend’s Mickey Thompson Tires WCHRA Finals, Hentry parlayed that testing performance into a runner-up finish at Famoso, coming up short of #1 qualifier Jeff Kyle in the final round, 5.13 to a 5.24.
