I've seen a Ford Super Duty run a low 11 on 8" of lift and some giant mudders. Well, seeing = trying to peer through a giant cloud of black diesel smoke...It was wonderful.



On N/A vs Turbo.... Turbo is just plain more efficient. It can develop more horsepower per liter than anything N/A tuned. Engines are nothing more than air pumps, whichever one can ingest more air is more efficient, can make more horsepower. Turbo motors can reach obscene volumetric efficiency. It's not difficult to reach triple the efficiency of a similarly designed engine. The tradeoff is heat, but that heat can be handled.

V8 and larger engines only exist to sidestep the problem N/A engines have with ingesting enough air to make solid horsepower, it's a sledghammer approach. Obviously there are a variety of technical hurdles, for both turbo and N/A...just look at the average horsepower of each sort of engine across the past few years, both have seen a solid increase. But one way or another, if you want more horsepower, get a turbo car. Anyone passing judgement without driving one first is a loon. (Obviously you can go get a Vett and rock 505 HP... I'm more pointing at the future of cars here. I'm of the mind we will slowly watch displacements fall for higher HP v6s and 4cylinder turbo cars.)

And don't point at top fuel and say it's N/A and makes more HP than turbo >.<

Anyway, for a asskicking performance sedan, give me a low displacement Turbo V8. something that revs to about 12k

 

i like the turbo aspect because they make great power and you laways have options and room for more. I like the N/a because of the low end power and the fact there is nothing but your engine making you go. I think turbos are meant for smaller engins that literally need it to go fast. I think a V8 should pull its own weight no matter what. A heavy V8 that is making a small amount more power than a turbo 6 makes no sense. the V8 should have loads more power and loads more toruqe unless of course the turbo car is built, but stock wise. maybe ill look into a natural aspirated top fuel engine for my audi

 

My point was (or, atleast the one I ended up with) was that big V8's don't have to be heavy for the power they're putting out. That link I posted showed it clear enough.

Truck tuned EcoBoost 3.5L, 365HP/420ftlbs = 450lbs

Coyote 5.0L in the base GT, 412HP/412ftlbs = 430lbs

I'm not even touching the fuel economy issue. If you care what your fuel bill is you're not going to be looking at an RS4. I'm also not saying Honda Civics or A4s should have V8s. The N/A and FI 4, 5, and 6 cylinder engines all have their place.

 

Fuel is fuel - you have to buy it either way, if you can afford an RS4 you can afford the gas. V8s should also be used in the correct applications i agree. I can wait to see the day a civic gets a V8 from the factory.

 

I thought top fuel cars were supercharged (definitely not n/a).
