400mph club: Danny Thompson breaks father’s speed record

1 September, 2016

We’re all familiar with the name Mickey Thompson, but we’re not so familiar with his son Danny. Ever since Mickey was murdered in 1988, Danny has endeavoured to follow in his father’s footsteps. Until just recently, Danny has been chasing his father’s 400mph-plus record in a vehicle designed by Mickey. Mickey’s ’60s-designed streamliner, named Challenger 2, is an aerodynamics masterpiece, designed in a time when CAD didn’t exist and engine technology was nowhere near as close to what it is now. During the August 13–19 Speed Week at the Bonneville Salt Flats in Utah, Danny broke his father’s record by a tenth of a second with a 656.23kph (407.767mph) run. 

If only it was as easy as running that speed once, then calling it a record. Unfortunately it’s much tougher than that as drivers have to prove over two runs that their vehicle can pull that speed. The times are then averaged out and used officially. 

If you thought the engines that propelled Challenger 2 back in the ’60s were still in place, you were wrong. Now Challenger 2 runs two 2500hp dry-block Hemis with an 80-per-cent nitro load. According to Danny, once the engines were installed, the rest of the drivetrain had to be designed around them to cope with the newfound power. 

“I can’t quit. We call it salt fever. You just want to come back to Bonneville. You just want to go faster,” Danny said in an interview with CNN. Danny is confident the Challenger will run in the 725–756kph (450–470mph) range in the future, potentially making it the fastest piston-powered vehicle in the world, with the current record being held by Speed Demon at 439.562mph. 

More to the point

This Daimler SP252 is so rare, few people know it exists. It’s one of a kind. It’s the only surviving, in fact the only SP252 ever completed; the would-be successor to the SP250 Daimler Dart. It is also the last sports car to have been designed by Jaguar’s legendary founder, Sir William Lyons.
Perhaps one of the original Dart’s biggest problems was it’s somewhat-divisive looks. It certainly went well enough to win fans, although Sir William wasn’t among them. It crushed the opposition in the Bathurst six-hour race, finishing five laps ahead of anyone else, and it was snapped up by police forces in Britain, Australia, and New Zealand, as it was the fastest thing on the road.
So you’d think a stunning new body with the magic Lyons touch would have been a surefire success. Why this car never made it into production is still something of a mystery, as the official explanations barely stack up.

Polishing to perfection

The secret to a show-stopping finish is colour sanding, no matter which paint system you use. Even a good painter, no matter how experienced or talented — like my mate Bruce Haye, CEO at Ace Panel and Paint in Whitianga — can’t shoot to a perfect mirror finish. To get that level of perfection, you need to colour sand.
It used to be called ‘rubbing out’ or ‘cutting’, and it was done with pastes that came in cans. They worked — sort of — but the compounds really just rounded off imperfections instead of eliminating them, and they removed a lot of paint in the process. But now your new finish can be made flawless, thanks to microfine sandpapers that come in 1000, 1500, 2000, and even 2500 grit ranges, and Farecla G3 polish — available from automotive paint suppliers.
