No-prep drag racing strips away the sticky, prepped launch pads that make horsepower predictable, and that chaos is where Chris Hamilton’s small-block turbo Mustang, known to Street Outlaws fans as BoostedGT, has built its reputation. Running as little as 347 cubic inches backed by a pair of 88mm turbos, the car regularly beats bigger, naturally aspirated rivals at grudge events like Bounty Hunters. The formula trades displacement for boost and tunability, which turns out to matter more than raw cubic inches once the track gets slippery.
390 cubic inches of BOOSTED fury! This small block Ford Mustang is notorious for taking down the big dogs! With original body panels, a small motor and an 88mm turbo – Boosted GT ALWAYS finds a way to get down the track in one piece, and USUALLY ahead of his opponent! He met his match here at Bounty Hunters No-Prep race, against a similar generation Mustang packed with enough nitrous to send us to the moon!
No-prep drag racing throws out most of the rules that keep grip predictable: there’s no VHT, no groove, just raw pavement and whatever traction a driver can find on the fly. It’s a format built for chaos, and chaos is exactly where one small-block Ford Mustang has made its name. Behind the wheel is a driver most gearheads know from cable television, running a car that, on paper, gives up displacement to nearly everyone he lines up against. Yet at event after event, including a notorious head-to-head at a Texas grudge race called Bounty Hunters, that undersized Mustang keeps finding its way to the stripe first. The reason has less to do with cubic inches than with what’s strapped to the side of the block.

A Small-Block Built to Punch Above Its Weight
The car belongs to Chris Hamilton, known to Street Outlaws fans and no-prep crowds simply as BoostedGT, and it’s built around a Ford small-block rather than the big-inch engines that dominate most grudge-race grids. Across different builds, that engine has ranged from roughly 347 to 420 cubic inches, a fraction of the displacement fielded by many of his no-prep rivals, and it wears the Mustang’s original body panels rather than a tube-chassis shell.
Turbos Instead of Cubic Inches
What makes up the difference is boost. The Mustang runs a pair of massive turbochargers, 88mm units in some builds, put together with kits from shops like Pressurized Solutions, giving the small-block enough forced induction to hang with cars carrying hundreds more cubic inches of naturally aspirated or nitrous-fed power. It’s a philosophy that trades displacement for plumbing, and on a no-prep surface where instant, controllable power matters as much as peak output, that trade has paid off again and again.
No-prep racing rewards exactly that kind of adaptability. Without a prepped, sticky launch pad, drivers are fighting the track as much as their opponent, and a turbocharged combination that can be tuned and modulated on the fly tends to out-perform a big, peaky nitrous motor that either hooks or doesn’t.
Events like Bounty Hunters have become proving grounds for that exact debate, big-inch builds versus boosted small-blocks, and BoostedGT has built a reputation as one of the format’s most consistent threats specifically because his Mustang can put power down when the track won’t cooperate.
It’s a reminder that in no-prep racing, the biggest engine in the lineup doesn’t always win the day. Sometimes the car that adapts fastest to a bad surface is the one still standing at the top end.
