Aussie Classic Mustang Makes 1,546 Rear-wheel Horsepower
Formerly a six-cylinder record-holder, this V8-powered 1965 Ford Mustang is shooting for sevens.
The video above comes to us from the Fullboost YouTube channel and it features one of the quickest classic Ford Mustang coupes in the world. This car was built by Australian race John Colaidis, who turned heads and set records with a local-market inline-six, but after moving that engine into a new project, the decision was made to install a big, twin turbo V8 in the classic pony car.
To be exact, Colaidis has installed a 427-cubic inch V8 that sends over 1,500 horsepower to the rear wheels with the hopes of running seven-second quarter mile times, but he bigger goal is to drive and enjoy this 1965 Ford Mustang.
Orange Right-drive Mustang
The 1965 Ford Mustang shown here is quite popular in Australia and online, as this car formerly set a world record for being the quickest car Down Under running on Liquefied Petroleum Gas (LPG). While this car still had the 4.0-liter inline-six with a big turbo and a unique fuel system designed to run compressed propane, Colaidis ran an 8.97 at 154 miles per hour, making it the quickest car in Australia running on LPG.
Next, he removed the LPG items and added a fuel injection system designed to run on E85, at which point this 1965 Ford Mustang got down to a best time of 8.17 at 172 miles per hour. That is nothing short of amazing for an inline-six, but recognizing the limitations of this engine in the Mustang, he removed the engine for another project, making room for a big V8.
Colaidis installed a 427-cubic inch Windsor V8 built by Heathcote Race Engines and fitted with a Haltech EFI by Tunnel Vision. That engine is mated to the same PowerGlide transmission and rear differential as the previous 4.0-liter, but after installing the boosted V8, the car was bolted up to a hub dyno to measure the wheel horsepower of this wicked pony.
The dyno action with this gorgeous 1965 coupe begins with low boost, but even on 6 pounds, the result is a whopping 785 horsepower. When the boost is lifted to 9 pounds, horsepower climbed to 875 and at 11 pounds, this classic Ford broke into the four-figure mark, laying down 1,043.8 horsepower, but that was just the beginning.
The boost level is gradually increased more from 17 pounds up to 26 pounds while horsepower at the hubs climbs from 1,217.5 to a 1,512.6. Finally, the last pull is made with 28 pounds of boost and the result is 1,546 horsepower at the rear hubs.
Talking with the Owner
After the dyno runs, we hear from Colaidis, who states that he is happy with the output of 1,546 rear wheel horsepower. He explains that he plans to get to the track a few times with the hopes of getting into the seven-second range, but he isn’t as worried about chasing numbers as he is tearing up the street and enjoying his wicked, twin turbo Mustang.
