I can't see any white knuckles on a steering wheel through the right-hand door so suspect it is not UK.

Got me thinking now, may as well air my thoughts as well

- Utube id says uk resident,

“Dyno Dynamics” 4wd dyno set up in the shop, not sure weather the orientation of this is of any benefit for a left hand or right hand steer though. These are common in Australia though

Engine cover resting against the wall looks very similar to the ones sold on the LS1 SS Commodores in Australia, not sure if this was common to the US as well,

I don’t think its twin turbo, doesn’t look nearly aggressive enough in the way it delivers its power, there is no savage hit of torque as it comes on boost and all I can hear is tyre noise.

Also does not look like an Hewland transaxle that I could find pics of

This next bit is speculation…
Exhaust fire of engine is most likely linked to a spark cut in the ECU, the throttle would be left wide open, spark/fuel cut causes engine to momentarily hesitate, allowing the pressure to come of the gears in the box. At this point the air shift system is operated and the dogs (or very good synchros) engage the next gear. ECU then automatically applies full fuel and spark advance for engine rpm. This would result in unburnt fuel/air mix in the exhaust system which could be ignited by any number of sources.

Does that sound plausible?


Anyone got further details?

It's running a LS1, not sure if it's TT.

The pipes running up to the bulkhead look like they may be going to turbos mounted near the bulkhead??

Less than half the price of a RT12 I'll bet!!

You wanna take that to one of the the PH Vmaxes at Brunters. They have a Pork one and two on about 212mph I think. Next one in March.
