What is it? I'm confused..
Well, as we can clearly see Ford has released their V6 2011 Mustang. 305HP, V6. N/A... Hype for the new 5.0 is 400hp, N/A... Though why is it so hard for the 4.6 to reach 400 HP N/A ? What is it about this engine that the only way to make any decent power is through supercharging it? There are V6's capable of making more power N/A then we seem to be able to squeeze out... I realize there is a difference between HP and RWHP, but if Nissan, Porsche, etc can do it... why can't we? How is a 3.7 liter, squeezing out the same HP as us stock, and I'm sure there will be room for more. Sad sad sad...

Compression and airflow.
more compression=more power, but require premium fuel.
bigger valves and more valves per cylinder. The engine is an air pump=more air in and out means more fuel can be added which=more power.
plus nissan and porsche engines are usually maxed out on power and dont respond well to bolt on mods.

That's one thing I've been wondering about the new V6 is what kind of fuel is going to be required? It seems like to me, to get that kind of power out of 3.7L you need high compression which is not going to work well w/ 87 octane. If the car starts to require premium, that will put a lot of people off that would otherwise want the car. 30mpg is great but it's not so great to a lot of people if you require the most expensive gas available.

The 4.6L doesn't make a lot of power because it just isn't a very technological motor. It doesn't even have 4 valves per cylinder. Every Honda since like, 1992 has had 4 valves per cylinder. It doesn't have variable valve timing or anything else. It has pretty low compression so it can run on 87 octane. It's just a basic workhorse motor.
Look at it this way, how many other cars run 13's stock with 87 octane?

But I think they're both the same thing.

05-10 has variable cam timing. It can actually change the positing of the camshaft by using oil pressure. Very simple yet very effective. There was an article in one of the magazines that said the 3v heads actually flowed better than the 4v and 2v heads. Not sure how or why but thats what the reported.
I had a G35. It had a 3.5L v6 in it with 285hp or so. That thing took FOREVER to get into the power band. V6s will never have the kind of power a v8 has unless you put a turbo or something on it. Yes the v6 has 305hp but it only has 280tq, thats 40 less than the v8. It makes a BIG difference, trust me.
