4-valve DOHC engine aircooled

[Bugat5speed]

Hi,

at the moment we are heading to a maximum of 98 mm bore, but the heads can be adjusted later. As the effect of power is much higher than with a 2-valve engine we will go for a maximum of 2.500 cc for the moment. Similiar engines (OHC, or DOHC) with only 2 valves gave more than 100 PS per 1.000 cc capacity. If it´s only 100 then the "small" 2.5 litre engine will give easy 250 PS.
Let´s see!

Next week a test on the flowbench will be done.
