One more point to help you, the small block Chevy V8 has been around for almost as long as Honda has been in existance. That should tell you all you need to know.

I don't see why everyone had to flip and tear this guy a new one. He was asking legit questions, albeit not worded perfectly. I'm glad there were good answers in this thread, at least.

Do you think it is hard to make 100 HP/ l engine?? I think every car manufacturer has knowledge on how to make that kind of engine. Question is how much that kind of engine would cost. LS engine are ohv engine and they have 2 valves per cylinder not 4 like most DOHC engine. Less intake valve (1 instead of two) usually means less air (less power). Also when you have 1 intake valve rather 2 this intake valve is heavier than the one in DOHC engine (2 intake valves) so valve float can accure on lower rpm than in DOHC engine.
Yes Honda makes 120 hp/l..but it still got 240 hp. I rather have 260 hp turbo engine. Not to mention ls3 with 430 hp.
Bmw v10 engine has over 100 hp/l also. And it weights around 250 kg. Find out how much does Ls7 weights.
Here in Europe you pay taxes on power (and on displacement) so hp/l can have effect on price of the car. But if you are talking about 4.0 l + 400+hp tax is very high so only rich people can afford that kind of car (at least in my country). They don't care what is Hp/l ratio.
If engine is doing a great job it doesn't matter what is hp/l of that engine.

If you want high rpm high HP/l ratio you can look at this engines
http://www.h1v8.com/page/page/1562068.htm
http://www.powertecengineering.com/p...s/v8engine.pdf
Now if only that engine wouldn't cost like completely new car with v8.

For some reason this engine seems more like a weekend toy type of engine that is only for 1 or 2 days a week.

What reason????
Small block are very reliabile.

The least expensive (and most reliable) way for a manufacturer to get an engine to produce more power is by going to a bigger displacement. Bigger displacement results in a better power band because of the improved low end torque. A big slow turning engine is also more thermally efficient than a small high revving one. Fat power bands also allow for crazy overdrive ratios for improved highway economy.

The power numbers for the S200 are slightly misleading. When does anyway wind those up to 8000 rpm? For the most part, mild acceleration (up to 5k or so) in those cars gets you ~130 hp. The SS at the same revs produces about 400 hp. Hmm, triple the engine size, triple the power . . .

Now for Ford. They don't have a 5.0 that produces 400 hp. But they are expected to introduce it into 2011 MY vehicles. One way that they get the improved power is through direct injection, something that GM is working on for their next generation of V8's. DI allows for a ~15% increase in power while improving fuel economy slightly. So without it, that engine would be making 340 hp or so, which is less than what the LS3 makes on a hp/L basis.

You gotta know that the LSx motors are rock solid and a great example of American engineering. The engine has only 2 enemies - water and mechanical over-revving.
My friend is the original owner of his '98 T/A that he has used from day 1 as his daily driver - winter and summer (He lives in Ottawa, Canada). The car has over 325,000 km. on the clock (203,000+ mi) and the engine (completely stock) has never been cracked open! The car has seen its share of autoX events and track days...
Routine maintenance according to the book, coupled with not abusing these engines (i.e. flooring the gas pedal when the engine is cold!) adds up to solid dependability and long engine life.

As well, it appears that when the new Ford 5.0 V8 engine finds its way into the Mustang for the 2010 MY, it will be making somewhere between 325 and 350 HP - not 400 HP as you suggest.
http://www.leftlanenews.com/next-gen...t-engines.html
Even if it does make 350 HP, there is perhaps a 1 HP/liter difference in output between the LS3 (depending on which version you compare) and the new Ford engine(with 3 valves/cylinder vs. the LS3's 2 valve engine?).
The question is, will Ford be able to match the 6.2 L engine's fuel economy with their 5.0 L engine?
... and who knows what the LS3 might be rated at by the time Ford's new engine hits the streets?

Best regardSS,

Elie
That article is a year old. Here's a newer one:
http://www.leftlanenews.com/2011-for...re-50l-v8.html

The power for the new 5.0 will be 400/400.

All that article says is upwards of 400. Nowhere does it state, yes it has 400 anything. Till Ford puts it in print its still just speculation.

Sure, Honda can make a NA 2.0L making relatively high peak HP ratings, but until you get it somewhere over 1,000,000 RPM it doesn't do anything. Small, NA engines designed for high peak HP are generally pretty gutless unless they're really strung out. Torque and power curves matter just as much when talking about performance. I personally also like the idea of more power out of less displacement. I think something in the 5.0-5.7L range making 400+hp and decent torque would be nice. I'd certainly be willing to allow some peakiness if the engine was rev happy enough. I'm just trying to say here that GM doesn't need 6.2L to make that output, but the large displacement does have torque and power curve advantages. Pros and Cons. Variety is the spice of life. /cliches.

more HP, More Torque, Excellent Reliability, easy to repair, not overly complicated all these add up to make it the best v8 ever

:troll:
I happen to agree with you, but let me play the Devil's advocate.

1. I respect the shit out of Termis. I've seen quite a few of them rock some GM faces. I would never buy one, but I know exactly how fast they can get for cheap. To blow off cars just because they come from a competing brand is ignorant. See more below.

2. Ummm.....I'm not willing to give that much information about myself.

3. I, and all of my GM thumping friends, know what JDM is and use it on a regular basis. Ignorance borne of prejudice is just dumb, especially when it comes to some damned good cars. How many car people don't know what JDM is? That's just dumb.

4. There are a lot of Camaro fans here that do just the same thing because it just doesn't match up with what they WANT from the car. Por ejemplo..

"How fast do you think the SS going to be?"
"Low 13s, high 12s if you're Ranger."
"NO WAY DUDE! IT'S GONNA RUN 12.5s!"

5. DZ302?

All I can say is WOW!!!... What a bunch of Haters... Some legit questions and some legit answers... Ohh and also a whole lot of B.S.
If you fellas haven't heard of the 5.0 Coyote engine from ford for 2011 putting out 400hp then you need to get out a lil more... Ohh then that means you haven't heard about the Turbo Ford is strapping on one their 4 or V6 engines and it also puts out 400hp with a helluva increase in gas mileage.... Wake up!!!... This from a Hemi fan...

Okay before I just skim thru the thread, But I finally had the patience to read the whole thread and I'M PISSED

To the ANTI-TROLLERS you guys are ****ing assholes

All the guy asked was "how is the reliability of the LS3/LS engines, "How does the new 5.0 Coyote engine achieve 400 horse with 5 liters over the 6 liter LS3" and he compares honda NA engines a bit, and you guys chew him a new ass..........FOR WHAT

MAYBE HE DRIVES HONDA'S FOR A LIVING "DICKHEADS" AND KNOW NOTHING ABOUT AMERICAN V8'S

Camaro forum or not... You chevy/GM people are obnoxious, rude, ignorant and have a very immature superiority complex that assa-nhing, If I was 1982camaro I would of said **** you guys I'm getting something else and GM would have lost a sell

Mods, sorry for the vent I'll take full responsibility for what I said, and issue me my warning or temporary ban and get it over with.......spare me the boring lecture and, All due respect DGthe3 should of said something about the ignorant post

Several people had attempted to make this point I think but only in a round about way. The ultimate truth is in the cruve. Look at the Hp and Tq curves for each of the engines. The LSX engines have flatter curves and offer greater power throughout the RPM range than any other engine on the market. You canot compare peak numbers because they are meaningless unless your running a CVT or something to operate at only one design point.

An engine will operate all over it's curve during it's lifetime not just as peak. you'll find that LSX engines have more available power more of the time than anything else out there. This makes them pleasant daily drivers and allows them great mpg. I would rather have a 300hp engine that makes 300hp for 80% of it's rpm range than a 400hp engine that only makes above 300hp for 25% of it's rpm range. Thats why comparing a Ford motor or a honda motor to an LS motor is idiotic at best.

It's going to be aluminum just like the current 4.6. The GT500 5.4 and the 4.0 V6 use cast iron block. The new 3.5 V6 will use aluminum blocks also.

I see that as a self fufilling prophecy. If people don't buy from GM due to warranty fear, the company will go under and it will become a justified fear. However, if nobody worried about it they wouldn't lose sales and things will be alright. Waay over simplified of course, but you get my point.

paper maché . . . lol . . . then again I suppose if they mixed it with enough epoxy it might hold up long enough for a couple of cycles. Sounds like an interesting project for someone.
