it is well possible, and in my experiance high comp engines are lovely to use versus low comp, my own engine is over 9.0:1 and is turboed and mapped to 2 bar of boost by MSD !!

ok so its a rally engine in a rally car , but , driveabilty is a serious key factor to smoothness in a rally car , i dont want the car to be very flat , then all of a sudden a massive boost spike , and if you think that they are lifed , i wouldnt expect to remove an engine for 20 events , thats approx 1800 miles at full flat out power , plus a load of road miles inbetween ,

so if you compare that to a road car which may see that amount of flat out use over what 3 years ??

food for thought !!
