CHARGE COOLING is not the way to go for higher output with our existing engines, so says Paul Gardner of L. Gardner and Sons Ltd.
This has been achieved by increasing both bore and stroke while retaining the same external dimensions.
The 6LXDT is intended to compete in the 180 to 210 kW (240 to 280 bhp) market sector.
The turbocharging of the eight cylinder Gardner engine which becomes the 8LXCT is another example of Gardner's continued move towards total turbocharging.
As Paul Gardner explained, "The naturally aspirated applica-. tion is likely to fade away in the future due to noise and exhaust emission requirements."
To confirm this, turbocharging the eight cylinder engine has reduced the noise level by four per cent.
The proposed new "big six" designated the 6LYT is now running on the test bed with its launch expected to be at the 1984 motor show.
This engine will be aimed at the 225 to 298 kW (300 to 400 bhp) sector with the first example likely to be rated at 238 kW (320 bhp).
"We will certainly not be stopping at 300 horsepower", said Mr Gardner.
"We must be in a position to respond as the market moves upwards in power requirement." Speaking at the launch of the new turbocharged eight-cylinder engine, Mr Gardner said that this was why the company had chosen to increase the capacity of the existing 6LXCT engine.
To be known as the 6LXDT (CM,April 24), the new engine will have a capacity of 12.7 lit (775 cu in) compared with the 10.45 lit (638 cu in) of the current engine.
