I think having a good amount if displacment, and then having a very good topend works well taking a car through the turns off boost gently, and them stomping it in the straights with maximum topend power.

A large amount of displacment would work in a track car, but would require more care with the power.

Drag cars work best with larger dislacment because you can control the launch better with alot of torque...unlike a boosted small engine witch requires brake boosting or slipping the clutch to get any good of a launch.

From a roll, a larger displacment engine wont perform as well as a topend machine because you have the lower powerband of the v8 wich is more suited for a fast launch vs the topend machine that likes its power in the higher revs and speeds.

There isnt such a thing as the fastest all around car in the world. The super cars of the world can get easily wipped by the high displacment drag cars of today...likewise I wanna see a drag car go against a ferrari on a curcuit.

Thats why theres a million different cars and engines...not everone llikes to drag race, not everyone likes to road race, and some people just want to fucking get to work without worrying
