Unfortunately the Charger was locked away in the paint shop over the whole lock-down period so Sonic ground to a halt with nothing to do but throw a turbo on my son Ryan’s Commodore.
Back to the Charger, after 2 different dyno sessions & a test day at Tokoroa, which all went well (other than a broken quick-change rear end shaft), we were set to strip the car for final panel & paint.
When we spec’d the rear end to Winters a few years back, they felt what they supplied (their Extremeliner) would be adequate, we were using a slick tyre with 200 mph gearing for our NZ testing and the shaft sheared in 2nd gear after a few runs. This never would have happened on the Salt as we have no initial traction with our skinny Salt tyres, but where it MAY have happened is at 200mph+ speeds, this is where we start to see loads on the drive train increase sharply due to aero & mechanical loading. If the shaft had sheared on the Salt, things would have been a lot worse, they have since made a stronger shaft which is now in the car.

There were a few little panel items that needed to be addressed, ENTER COVID !, car locked away for weeks !.
Then - into the paint shop to be blocked down/gapped as a complete car, then stripped, put on the rotisserie & final paint inside & out. After paint it was rust proofed & further seam-sealed to try & reduce the amount of salt getting into nooks & crannies.

Now (beginning of June) back on its wheels & back to Sonic. As at the end of June, the car is 90 % complete, once the car is complete we will test at a longer NZ venue to try & get some decent mph. We then convert the car back to the Salt set-up with wheels/tyres, diff ratio & few other little changes & get ready to head to Lake Gairdner , about 200ks north of Adelaide. Logistically this is a much harder event to run at, (even though its closer to us than Bonneville ) due to its isolation but the Sinclairs are up for the challenge, or adventure as they prefer to call it.
I’ll be back with testing news & pics pre Aussie in the next few months, stay safe, cheers, Mike (Bic)


We can build you a turn-key race car from the ground up, or we can fine-tune an existing race car. We can fabricate new items, or provide advice on getting the best from an existing set-up. Please visit our Projects page to see some of the work we have carried out for other customers. more info


So many modified and hobbyist road cars suffer from poor tuning, be it engine or chassis tuning. We like to focus on what we call 'driveability', ie, nice throttle application, carburettor, and chassis tuning.
