The post was on 2 valve cars stock vs mods Bob.... four valves do have an
inherent torque problem vs 2 tho, as well as a HP rating that is higher in
the rpm range as a general rule as well.... Looking at the audis, the move
to a 4 valve head is not necessarily the best way to go on the turbo apps....
Not unles you address the high static compression of the 4 valve
motors......
