It was nine months ago we first showcased the 454ci big-block packing ‘91 Mustang with a Vortech YSi-Trim supercharger. For their first event, H&H Racing’s, Kelly Henry piloted the Fox-body into the 8’s, running 5.79 at 126.73 mph in the eighth-mile and a string of 8.90s at 157 mph in the quarter-mile. (Vortech YSi Powers a 3,500 Pound Freight Train Into The 8’s!)
In an effort to step up to the West Coast Hot Rod Association’s x275 class, the team completely revamped their combination to a 525ci big-block, along with Vortech Engineering’s latest V28-123 supercharger and a CDS supercharger drive from Chris Alston’s Chassisworks. Dyno numbers have been kept under wraps, but rumored to be in the 2,000hp range at 35 psi.
During their debut at the WCHRA Chris Alston’s Chassisworks 5th Annual “Shootout at Sundown” in Famoso Raceway in Bakersfield, California; having power wasn’t an issue, instead it became a learning curve to control the new found steam. Even so, with just five passes on the big-inch powerplant, they were able to make it into the final round, taking runner up and running as quick as 5.69 at just 125 mph.
Two weeks later, the team returned to Famoso for a couple of eighth-mile test hits and started off with a 5.28 at 145 mph, coasting to 8.35 at 135 mph. For the second run, they added a couple degrees of timing and ran a 5.21 at 147 mph, coasting to an 8.36 at 128 mph! They’re still creeping into the power and only time will tell just how fast they will go.
Stay tuned as Kelly and Team H&H are headed to this weekend’s Mickey Thompson Tires 5th Annual WCHRA “West Coast” Finals at Famoso Raceway in Bakersfield, California.
Kelly and H&H Racing would like to thank his better half Melissa for putting up with the endless nights in the garage, crew members Tony Politano and Dustin Granger (aka Lunch Box), Bob Endress and everyone at Vortech Engineering for their support, Chris Alston’s Chassisworks, Rocco Acerrio of A.R.E. Performance & Machine in Simi Valley, CA for assembling the incredible powerplant, and to The Carb Shop in Ontario, CA for putting together the ultimate blow-through carburetor.
