Why in the blue hell are my lights dimming when i have a 250 amp alt?

Its not invalid as you keep changing the criteria of this "argument" in your head. As I have no clue what your really arguing, other then you keep saying well V8's can do that. If your talking all out then v8's will win. If your talking street cars then your not using near 1000hp so yes 4cyl's can be just as fast period. Again it comes down to this magic "criteria" that I'm not informed of.

Then I think we can agree that comparing apples to oranges produces less than definitive conclusions.
This started out as a '4 cyl engine cars can be just as fast as 8 cyl cars' and devolved into dohc engines are more efficient than tradition pushrod designed engines.

All I'm saying and have been saying is this:

of the production motors sold, the smaller motors tend to be more efficient than the V8's, mainly b/c they have to be

Which is where DOHC and pent roof combustion chambers come into play.

speed, you are blinded by the fact that you stepped into an argument that you simply can not win. You have changed the origional argument you stated and morphed it to suit your need of not losing the debate, however you have beed bested. now shut the hell up!

You are ignoring the simple concept than when all else is equal, more cubes will make more power. The only way to bypass this is to suggest 4-cyls utilize more power adders than their 8-cylinder counterparts.

Lol at this thread.

And Lol at the OP asking why are his lights dimming with that beast of an amp on stock battery, LAWLERS! No matter how big your alty is.....

I shouldnt be surprised though, he has always been an idiot since day one.

All of this

All of this

exactly

Right all else being equal, the discussion was about street cars(from your post), your traction limited so there's only so much power you can put to the tire. In this application its not about displacement or how much hp you can make as your limited by the tire and road surface. So yes in this instance all else being equal(street cars) a 4cyl can be just as fast

Which is what I've said all along(just got sidetracked)

So yes if you using a 36"x17.5" slick as in top fuel , then yes a V8 is the choice, but for 335 series street tires a 4cyl can burn them just as well

Traction has nothing to do with the discussion in comparing engines. If we are going to complicate things by discussing traction, we also have to consider what type of torque or stall converter is being used, tires being used, weight of the vehicles and weight transfer, etc. Traction is an outside factor that does not fit in the comparison of engine versus engine.

Just saying "street cars" does not make all other factors equal.

Dude make up your mind. Like I said I dont even know what we are discussing b/c you say its about street cars, now its about which engine makes the most power(hint, duh, the larger one). If you want to talk about engines what the heck ones are you even talking about??? If you want to talk about 4cyl vs V8, then in what situation?

Traction is the biggest factor from street to any other form of racing, so you cannot just magically make it a non factor

"street cars" implies that they are all limited to things on normal roads, limited traction, street tires, bumps(ride height), ect..

I'll jump in here just to make things thick as mud.

Mr SpeedEurphoria... Why do you keep changing the subject and morphing the original debate?

If you are comparing a V-8 ENGINE to a 4-cylinder ENGINE, that is one thing. If you are comparing a V-8 American car to a 4-cyl Import, that's another. Did you know that BMW makes V-8's? Did you know BMW also made a V-12? So to classify Imports and such as having smaller 4-cyl engines is ignorant. If you really want to go out on a limb, Lamborghini and Ferrari have extracted quite a bit of HP per CID....from their 12 cylinder engines. Most of the leading tech for engine design comes from Formula 1, especially since the racing teams have several Million tied up in each car. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Riddle me this. A bridgeported or peripheral ported Rotary engine can produce roughly 600hp from 1.3L displacement, turbocharged. It does this while getting around 8-15mpg. Sounds like a real efficient engine, especially for 1.3L and the amount of HP, doesn't it? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif My point is, lots of HP for a given displacement does NOT equal efficiency.

Im sorry you are having trouble following my point, maybe I haven't been clear enough.
I originally mentioned 'street cars' because the discussion started off about street legal vehicles. You used the most extreme race car you could find as an example of what a car with a small engine could do. This is not a realistic comparison. Later when I said that simply saying 'street cars' does not equal 'all other factors being equal' meant you still aren't comparing engines with the same power adders. "All other factors being equal" means the same forced induction, same flow characteristics, etc. Since our discussion was about whether or not 4-cyls can be just as powerful as 8-cyls, I dont see how comparing a 4-cyl with racing heads, nitrous, massive amounts of boost and a non restrictive exhaust system can be fairly compared to an 8-cyl engine with no forced induction, no nitrous, stock heads and an exhaust with a cat an mufflers.

Hope that clears up your confusion.

buy this
amazon.com: Boss cap35 35 farad capacitor: Automotive

it might work, plenty of people have said that capacitors actually fixed their light dimming issues. If it don't work, just return it.

you should be banned for like 4weeks for this post.......................
