MENTAL UNIT

-

Aaron Costello’s ‘UNIT’ is one of our all-time favourite Camaros, and, although it has not raced for a few seasons now, it did previously run into the mid-nine-second zone thanks to the procharged 572ci big block engine. That combo’s now a thing of the past, as Aaron has made the switch to an engine that, while more streetable, may end up offering more power in the long term. The new set-up is based around a six-litre LS2 engine fitted with custom pistons, a custom cam, and custom timing gear — an arrangemen­t that Aaron says is, in reality, pretty mild. Where it gets not so mild is with the addition of twin Garrett GT3582R turbos from the turbo king himself, Steve Morris of the US. Wanting the configurat­ion to look right, Aaron’s opted for a mirror-image set-up, which, we’re sure you’ll agree, looks just the part. At this stage, the fuel system has yet to be sorted. However, a Steve Morris plug-and-play Holley ECU has been ordered. The goal of the exercise has been to give the car some more street manners and drop noise levels — something that, thanks to the twin-turbo set-up, is bound to be achieved. All going to plan, the overall weight will also be lighter than the previous cast-iron big block and ProCharger combo. At this stage, Aaron’s hoping to have the car running around Christmas. He isn’t chasing outright power, but hoping for around 600hp at the wheels on 98 octane pump gas and closer to 800hp on E85, with the potential for more in the future when the boost is wound up.
