spoke to 'yellow1600rally' about it today.
Its taken 3 blown up les collins built motors to get it where its at now. I highly doubt it is 1600cc any more
. A figure of approx 15k got shot into my ear...for the engine alone
It's only blown 1 motor... (at phillip island, being revved too hard, baked the oil and snapped a rod)
The second motor had a "harmonic issue" and kept braking the rotor button, ratttled a rocker arm off, caused the engine to backfire and nearly caught the car on fire buy lighting up the air fillter socks, so back to Les it went...
The third motor, the one that was in the car at Winton, revs and pulls hard all the way too 8,500rpm, it can go to nine but doesnt produce any more power... The same motor is now back out of the car getting some new valve springs, two or three decided they didnt want to play anymore and broke while the car was last racing down in tassie...
It is still 1600cc, the car is built to group N regulations which only allows the same engine capacity that was run back in the day, also only allowed a 4 speed gear box, drum brake rear end, 13 inch wheels, no major modifications to suspension ie no major re-location of mounting points, no lengthing of control arms, no rose-joints instead of bushes etc etc...
Its fast due to its light weight build... and countless man hours to make the most of what you lack by still running a 1600cc engine, and the nut behind the wheel steers it pretty well...
