THE ULTIMATE DOOM
The new BMW M3 will have one (the last one had a V8 ) and The M6 has a twin Turbo V8 (the last one had a V10 ). With fuel prices going up, I don't understand my American car makers; they think the only way to increase power is to increase displacement. I have nothing against big engines, I simply would like to see these companies develop a better car. for example, Instead of OHV, they should make their engines with DOHC and 4 valves per cylinder
Aha, you give me a hearty laugh. I am not surprised in the very slightest you'd go straight for "lets put a TT Inline 6 in there" for just about any car, you'd probably even say the same if I said "What engine should I put in my weed whacker?"
I mean, 50% of the posts you post in The Garage are all "I love the GT-R", "GT-R is best", " I wonder if anyone notices I love the GT-R", " Did I mention I love the GT-R?"
Sorry dude, the Corvette will not get anything but a large-displacement V8. Period. Sometimes it'll be supercharged (LS9), and sometimes it'll be turboed (B2K Callaway), but it's going to have 8 cylinders, and a s**t ton of displacement.
I do not know where you get off saying that OHV is a less efficient design than SOHC or DOHC. As a matter of fact, American muscle cars already do have these technologies (that new-fangled 5.0 32v Ford Mustang engine), and, if it wasn't for the Mustang's VVT technology, it would only be a top-end vehicle (well, that, and the fact it has very large ports. Remember, one very large port will always conduct more and better air flow than two ports taking up the same space. They will not have the same surface area of the bigger port and they will have slightly combatting air flow streams.) Wow that was a long bracket.
2 Valves per cylinder is an efficient setup. As is pushrod. You may hear some people say "DOHC is more efficient than OHV", and that is both correct AND incorrect.
By power, it is less efficient. I mean c'mon, just think about it. What takes more power to spin? One heavy metal rod with lobes on it or two? If you answered one, you're correct.
Now, by task distribution, it is more efficient. By putting less stress on each valvetrain component, you can rev higher reliably. It just makes sense; the same load distributed to two camshafts (and valvetrain assemblies) will be much less stressed than the same load put on one camshaft (and assembly.) Therefore, there is more overhead potential to work with.
If revs is your goal, then DOHC and 5-valves per cylinder is your ticket; just ask the performance variants of the 4A-GE. Though revs is not the goal in the SBC series, reliable torque with a usable powerband is; and so, large-displacement V8s with 2-valves per cylinder will stay. The Corvette may one day incorporate more valves per cylinder (3-valves per cylinder was the original idea for the LS7), but the point I'm trying to make is that OHV is not an ineffcient technology whatsoever.
If it tickles your lower parts at all, the new engine will have VVT technology. So... Yeah... Be happy about it?
Oh yeah, PS. Without the turbochargers, both the RB engine series and the VR series engines are absolute dogs.
