Forgive me if this is a dumb question, but how exactly does the GT make that much more power with only.6 more liters of displacement and lower compression? Do the V6 heads and cam suck that bad or does two extra cylinders help with more than just the added displacement? Just a curiosity Jeff

I would guess heads and c/r. The heads on these new 3V's are the ****.

Did you forget about the extra 2 cylinders? Doesn't BMW have a 4.0L v8 that makes more power than the gt?

Aren't the 6rs good for 225bhp? and the 4.6 good for 300bhp....

The C/R on the v6 is higher than the GT. Yeah 3v has gotta help I guess. Mossestang very funny I'm just wondering if apples to apples 2 cylinders is inherently better, ie. would a hypothetical 4.5 V6 be equal to a 4.5 v8? or does spreading out the displacement have an advantage?

Yes spreading the displacement does make a difference. Reving etc. Less rotating mass... shorter stroke.

because no one knows how to explain this but what to think they do yes it does have an advantage, but the 4.6 is also more efficient the way everything works together, and yeah, damn bimmers have a sick new V8

I got to thinking.. I had a 4.3 V6 stock had more power than a 305 V8.. Thats chebbies.. if that has anything to do with this.. Its all in the motor.. If its a good motor or a sucky motor.. Did that make any sense or do anything to do with this??

That has everything to do with it. H302 Saleen w/ forged internals - 580 hp. Z51 vette 7L with supercharger and 600 hp. hmmmmm....

And yeah that lower rotating mass and shorter stroke makes it a screamer. small displacement, high-flow and FI, great combo.
