Don Lamana is another name to add to the list of X275 racers with his new car receiving the finishing touches over at Pro Fab Performance in
Thonotosassa, Fla. Lamana has been racing his Tremec True Street-turned-Ultimate Street turbocharged Mustang coupe for a few years now, with his most recent accomplishment a runner-up finish in Drag Radial at NMRA’s Spring Break Shootout, where he logged a personal best 8.16 at 169 MPH during the event at Bradenton in March.
Matt LaRue from Pro Fab Performance recently posted some photos over at Yellow Bullet of the build. Until then it was a bit under the radar, unlike some other recent and controversial builds.
‘We’ve been at this about two years now, from True Street to Ultimate Street/x275,” explained Lamana. “The little silver car will now be an index and Ultimate Street car that my wife, Jeri, will eventually pilot at the local events. I’ll will do double duty at Donald’s race in September, running x275 with the new car and Ultimate Street with the silver car. Jeri won’t be ready to go five teens in Ultimate by then so she’ll start locally running 6.50 index. We’re both rookies to heads-up racing but I think we have the tools to be competitive.”
With few events locally to run competitively with the Ultimate Street car as well as a desire to step into the hottest Radial tire class going, a clean four-cylinder coupe was sourced in June of last year and promptly stripped and gutted by the folks at Pro Fab Performance.

A 25.3 cage was constructed, mini tubs installed and most of the other fabrication to the body and frame finished, then it was off to paint last September. Here the Pro Line built small block Ford sits between the rails for mockup. Photo courtesy Pro Fab Performance.
Before and after, on the rack. The car was taken to Brand Customs in New Port Richey for the paint and body work. They had it finished in about a week and it was sent back to Pro Fab for final assembly. Photo courtesy Pro Fab Performance.

The rear suspension is from Wolfe Racecraft. A Category 5 nine-inch housing is filled with Moser internals, including 40-spline axles. Rear brakes and double adjustable shocks are also from Strange Engineering and feature a dual caliper setup - better suited to hold the car on the line while building boost.

With the nose off the first thing that pops out is the modular Exile X275 legal 88 mm turbo. Also note the unique placement of the fuel tank and intercooler, on the right and left respectively.
