MITCH Bean’s ’68 Camaro finished third in the K&N Dial Your Own class at our first Drag Challenge Weekend early in 2018. Running nines across the three days, the twin-turbo LS-powered F-body cracked into the eight-second bracket not long after our three-day event, but all wasn’t well with the alloy LS2 under the bonnet.

Chev Camaro“After Drag Challenge Weekend we wound some more boost in and it went 8.8@151mph, but the oil pressure was reading low,” Mitch explains. “We checked the logs and it seemed fine, so I went back out and ran an 8.90, then put it on the trailer, took it home and stuffed it in the shed. Later on I cut the filter open and it was full of copper; the motor had spun a bearing!

“It now has an iron 6.0-litre LQ9 grout-filled to the water jackets, so we can wind the boost up. I also changed to a Moroso sump and it now holds 10 litres of oil.”

“We need bigger turbos now, as they’re out of puff,” Mitch says. “It went 8.80 on 19psi but we have 22psi in it currently. It’s making that much power the rear shocks are topping out, so I need a set of coil-overs so we can get some more travel and adjustment.”

I don’t know what they are, but they’re bigger than what I’ve got!”

Don’t think he is looking to turn it into a trailer queen, however. After playing with plenty of other cars and engine combos through the years, including a tough aspirated plastic motor that ran eights in a tube-fronted race car, Mitch grabbed his ’68 Camaro for more street-oriented duties.

I bought it with an aluminium LS2 already in it, and it had gone 10.60s. We’ve now gone 8.76@154mph, and I’m hoping we can get into the 8.50s!”

Mitch BeanMitchell Bean is a familiar face at Willowbank Raceway. He’s probably best-known for his tough, race-only FJ ute that ran a best of 8.80 thanks a stout aspirated Holden 355. These days he’s enjoying the street ’n’ strip lifestyle with his wife Kim and son Kyan, both of whom joined in on Drag Challenge Weekend

With the whole car blue-plated to keep it legal in Queensland, Mitch is dead keen to keep racing and cruising the 3650lb F-body. “It is going great and we had a great time at Drag Challenge Weekend, apart from a minor cooling issue due to some wiring, so I am really keen to do it again,” he says. “It is in the shed at the moment, but we’ll take it out for a run this weekend. It really is awesome to drive.”
