Jay Robinson's turbo 13B-powered Mazda Capella - Drag Challenge profile

THE only rotary competitor at Drag Challenge for the past two years, Jay Robinson was back with his turbo 13B-powered 1977 Mazda Capella, and for 2019 he’d moved to the new Tuff Mounts 235 Blown class

“The 235 is the biggest tyre I could fit on the car,” he said. “After DC18 we got the engine balanced and had Xtreme Rotaries make some cooling changes to it. We fitted the FD RX-7 intake manifold, and are now running E85 at the track.”

Controlling the deal is a MicroTech LT10S ECU, and Jay is only pushing 22psi of boost at the moment, but still made 495rwhp on E85. “We ran the same boost last year with the old engine and it made 430rwhp,” he said.

While they have a reputation as temperamental things, Jay’s rotor ran good times all week at Drag Challenge 2019, with a 10.89@127mph on Day One backed up by a 9.77@132mph on Day Five. Over the eighth-mile he knocked out a 6.80@103mph on Day Two, a 6.44@109mph on Day Three and a 7.12@110mph on Day Four.

“The car went flawlessly this year,” he said. “I had a couple of little teething issues, as my first drive was the one to Calder on Sunday, but I finally got a decent pass on Friday!”
