I am stupid when it comes to engines but if rally cars used to run low comp and now run high comp and everybody follows the trend... would time not be better spent in developing the high revving aka Karls engine or develop say a turbo vtec style type engine ???

will the trend stretch to gearboxes They used to run 6 or 7 speed for rally cars and still do but now the likes of Pug team run a 4 speed box so will everyone be going for a 4 speed downgrade conversion I mean havent we come from there allready back in the day
