Ford Granada Sleeper ZZZ ZZZ
You may or may not have heard of the term “Sleeper Car” before – to some it probably sounds like a camper van vehicle or caravan – however, a Sleeper Car is the complete opposite of the meaning derived from the word “Sleeper”.
As you’ve most likely guessed from the title, this type of vehicle is a bog standard car hiding and possessing enormous amounts of power under its coat.
Example: How great would it be to embarrass a Porsche at the lights in an old Mitsubishi Galant? How is this done? Mitsubishi are primarily known for their EVO cars, the ultimate turbo tuning machines. Despite this, their Galant VR4 (pretty standard in appearance) comes with 276 bhp stock, so with some tuning and performance upgrades at a relatively low cost, they can be boosted to around 600+ bhp.

Depending on your budget, any car can be transformed into a Sleeper car. I recently watched an episode of Fast N’ Loud on Discovery where Richard Rawlings and Aaron Kaufman took an old ’59 Rambler Wagon (pic below), treated and clear coated its weathered body for effect, but installed a massive 4.8L Chevrolet V8 with an Edelbrock Carburettor and MSD direct ignition and disk brakes. From the outside it looked like an old truck, but a blip of the gas and it could shift tectonic plates.
One problem you face boosting horsepower is hiding the upgrades needed to cope with the extra grunt. The main two are exhausts and brake callipers. Unless you purchase black callipers, simply paint them before installation. Exhausts are pretty simple if you can get under the car – ensure they are out of sight but still manage to function properly. Sports exhausts usually offer different styles, either for sound or performance. Try and pick one that offers optimum flow as well as offering a good amount of muffle – a deep rumbling exhaust suggests upgrades.
If you have bottomless pit of money to throw at car, check this Sleeper Car out for scaring pretty much any other potential racer at the lights. This is essentially an F1 powered Alfa 164 Procar. It was built in cooperation with Brabham and possess the only Alfa Romeo V10 ever built. This disguised Alfa produces 605 bhp at 12,000 rpm! – not sure what the insurance premium would be on this one.

My favourite and perhaps the ultimate Sleeper is “Farm Truck” from the TV show Street Outlaws – check out the video below and witness the power that old truck can lay down.
If you are thinking about creating a Sleeper Car with a small budget, aim for a small and light turbo car, something you can add a cold air intake and bigger exhaust to, also one in which an ECU tweak is viable. These three options can add as much as 60-80 bhp to a small turbo car, putting you in the same arena as the bigger sporty saloons.
