The Kiwi Bear Corrections – McLaren Offy M15

Firstly a big thanks to racer Jerry Entin who kindly corrected a blog I posted a couple of years ago about Denis Hulme’s participation in the 1970 Indy 500 and has kindly sent some additional photo’s from the IMS Archive to complete the story.

For 1970 Bruce McLaren had Gordon Coppock design the first McLaren Indy 500 challenger, above the #73 McLaren Offy M15 is seen in the Indy pit lane with Denny at the wheel, Tyler Alexander crouched beside him and Teddy Mayer with clip board on the pit wall. Jerry tells me the little guy in the back ground is Chickie Hirashima a well known crew chief and Offy engine builder.

The turbocharged Offenhauser’s that McLaren used were prepared by George Bolthoff (R) with help from the legendary Herb “Herbie Horsepower” Porter (L) of Speedway Engines.

his team mate in the #75 McLaren Offy M15 was to have been fellow New Zealander Chris Amon with whom team owner Bruce McLaren had won the 1966 Le Mans 24 Hours driving a Ford GT40.

Team owner Bruce McLaren, seen above squatting next to Denny, had tested the #79 M15 making a big impression driving in convoy with his #73 and #75 entries on the opening day of practice for the 1970 Indy 500 and Denny was to shake down the #79 back up car to cover all eventualities.

However the #79 developed a methanol fuel leak,

which caught fire, the only evidence of the fire in the photo above is the clearly visible heat haze above the far front wheel as Denny prepares to jump and roll away from his car which was still traveling at 70 mph.

Denny received severe burns to his hands which forced him to miss the Indy 500 and the next two Grand Prix however within a month he was back behind of the wheel of his McLaren Chevrolet M8D Can Am car winning the series with six race victories, a string of three third place finishes also helped Denny secure 4th place in the world drivers championship all while his hands were still healing.

Teddy Mayer engaged Peter Revson to replace Denny in the #73 for the Indy 500, Peter qualified 16th but retired and was classified 22nd.

On seeing the extent of his countryman Denny’s injuries Chris Amon was not impressed with the Indy safety facilities and withdrew from the race.

Chris’s place in the #75 was taken by Carl Williams who qualified 19th and brought the car home 8th to record McLaren’s first finish in the Indy 500. The teams next design the M16 would become the class of the field in early 1970’s taking wins with Mark Donohue driving in 1972 and Johnny Rutherford in 1974 and 1976.

However team owner Bruce McLaren would not see any of these success he was killed a couple of days after the 1970 Indy 500 testing a McLaren Chevrolet M8D Can Am car at Goodwood. Team manager Teddy Mayer took over the running of the Bruce’s legacy which is now the second oldest team in Grand Prix racing behind Ferrari.

My thanks to Jerry Entin, IMS Archive, Ed and Steve Arnaudin who made today’s blog possible and apologies for any confusion caused by getting the car Denny was driving when he got injured wrong in the original post.
