is there a true replacement for displacement when it comes to engine size. I mean i know technology and design are factors, but if a larger engine where matched in design and technology, would a smaller engine still have power advantages? no idiotic replies please...

But what if a lager engine had a "thumping turbo charger"? i am starting to believe that displacement is the ultimate power builder...

What are you talking about? The 4G63 is basically a bullet proof engine. Its super reliable and can handle 25psi with basic bolt ons easily. Its also has an amazing warranty. If you have to go and take it in for work every few miles you dont know how to drive a car. Anyone with knowledge of the evo would disagree with what you say and AMS would kick your ass.

when it comes down to fair comparisons no.

you want to compare turbo fours to NA 8's? how nabout a turbo four's to superchaged 8's? easy 800 horsepower and 700+ foot pound with nothing but the charger and maybe a cam.

aba is not amused, sig was removed

i totally agree with that. i read a book about turbo charging cars and yes turbo chraging/super charging and engine to 1 bar (14.7 psi) is the equivilent of doubling the displacement.

sure the bottom ends on alot of 4 bangers are "bullet proof" so are alot of the v8's.

in racing there are only two real positives to using a smaller displacement engine. weight distribution and over all weight.

if you take a 2 liter 4 cylinder and have it rev up to 8k rpms it would produce less power/tq than a 2 liter 6 cylinder engine and less power than a 2 liter 8 cylinder engine. the latter progressively producing a smoother curve (better for everything pretty much) if they have the same redlines. can't have the same redlines due to rotational mass? look at f1 cars.

Sorry but that makes no sense at all. Your saying its not a fair comparison because a car with 4 less cylinders is turbocharged to a NA V8 with four more cylinders? A supercharged v8 would be an even more unfair comparison. Its funny because all domestic people will makes up excuses saying oh its not a fair comparison when a import is faster but then they'll say a Z06 is a fair comparison cause its faster. You can never win. There is no fair comparison, the OP asked if there was a replacement for displacement and there is. Domestic car owners with no open mind cannot accept that fact. I have nothing against American cars but some owners just think their cars are god when the 6.1L new challenger can't even take my 2.5L Turbo car in the 1/4 mile.

NO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


easy - LS series engine, 6 bolt main, can handle an insane amount of power,   stock bottom end is bullet proof.  

minor mods from a small block can produce over 500 hp and crank out any rpm you want.    and you can change rpm range with different builds very easy.  

upper end of small blocks is always the secret.   people can run 13:1 pistons and all that but if you dont have good heads on it,  then your killing the potential.  

take an LS7 and slap on a supercharger.    - drools...

if you want to see the potential of an LS3 look at the ZR1   6.2 liter supercharged.   630 hp.   reliably.

im a muscle man yes, but i like imports to. and its not a fair comparison why? add boost to one side, add boost to the other. like you said, he asked if there was a replacement, and there isn't with equivalent modifications.a stock V8 might not make as much power as a heavily modified turbo 4, but pump the same money into the V8 and the V8 will be more powerfull. and 1/4 mile times dont work to compare power, there are to many different factors, not to mention the fact that a more powerfull car might not be able to hook at the track. NA for NA, boosted for boosted, bigger engine=more power= faster car IF the engine is in the same car and if the car can still get traction.

Yes but if you read the question in the OP he is saying replacement for displacement. Therefore Smaller engine with a turbo vs Bigger engine. So you can either have a smaller straight 4 engine with the same amount of power as a V8 without having a V8 by adding a turbo or supercharger. Therefore replacement for displacement. Forced induction. However it only works up to a certain point and eventually displacement will always win.

oh i get it, a bunch of people who think you modify one engine to high hell than leave the other stock and wonder why ones faster. whatever.

Yes, abacus i now get what your saying and your right. To I Rossi though, yes many people mod their engines to hell and race stock cars on both sides of the spectrum. Who ever said racing was fair? What I'm saying is some of these cars can handle a ton more boost than a boosted v8 and can compete with even a boosted v8. Thats a fair comparison.
But actually if you looked at my link the ams evo would definitely match up with alot of supercharged/turboed v8s out there. 1131hp out of a 4 cylinder and did a 8.56 trapping at 171 mph. That would give alot of highly modified v8s an excellent show if not beat them. so whatever. I guarantee you ams's 4 cylinder can handle more boost than any built v8's.

IDK thats pretty damn similiar to me. Both modded heavily. Both over 1000hp. The reason why the 4g63 can compete with turboed v8s is it can handle ridiculous amounts of boost. The ams evo is at 55psi compared to a v8s that probably only single digits.

But the LSX was made to handle up to 2500 hp.

And Hot Rod Magazine tested cars that made ~1400 hp with only a supercharger and maybe some nitrous (I think only 3rd place used it).

haha you got me beat, I'm just saying though. Don't underestimate 4 cylinders lol. plus, the odds of running accross one of those cars on the streets with over 1000hp, not likely. lol

well lets see. A 400 Small Block or a 460 Big Block.

I would go with the 460 i can pull massive power from that block with new heads and a new intake or i could bore it and stroke it to a 552 and do the same put new heads and  intake
