That’s not what I said. what I said was “24% more power OR 24% better mileage.” The coyote weighs about 20 pounds more, and I said elsewhere that it is ~4.5 inches wider. I believe the new ZR1 ‘Vette has a hickey where the stupid charger lives, so that didn’t fit under the hood either.



You can’t possibly argue that…

No they haven’t. You might be able to advance or retard THE CAM, but you can’t control intake, exhaust and overlap separately.

Agreed. but Where does the power output of that extra 1.2L go? it is 24% larger so it should make 24% more power or 24% better fuel efficiency. But it doesn’t.

So is it the gearing? do they install big highway 2.XX gears to get the same kind of economy?

You are comparing apples to oranges, clearly. Any Ferrari guy will…

That could be due to any of several factors. compression ratio. weight of the truck itself. Gearing. Aerodynamics. All things aren’t equal here. By all things equal I meant the same displacement engine in the same exact automobile. One has DOHC and four valves per cylinder the other has pushrods. Hell, use the SAME…

Anecdotally, and yes appropriate of nothing, I personally own two 32V 4.6s is about 200K each. I have buddies getting close to half a million miles. The ‘new’ 5.0 is the same engine, plus VVT and direct injection.

I completely agree with your last two paragraphs, however here are four ways OHC/DOHC is better than…

Don’t call me sweetie.

*They’re
...and we weren’t even picking on the handling. yes, they drove like the QEII: 40 acres to turn around, dive and squat like a fat bulldog and wallows like the big fat pig it is.

Yeah, the roads these days suck, but Jesus, have some self respect.

No, you can’t. (anecdotally, sure) I have friends running 32V 4.6s with half a million miles.

I wondered how long it would take for someone to realize that you can’t really compare forced to NA.
Well done, sir.
A forced induction engine can run leaner stoichiometrically than a naturally aspirated, so there’s that.
HP/L doesn’t tell the whole story, but the weight difference is negligible. From…

Not necessarily.

Do you think the GT500'sDOHC Supercharged 5.4 needs a lot of RPM to make power? I’ll bet it will roast the meats as long as you keep your boot in it.

if you are going to use a smaller displacement engine, give it some steeper (numerically) gears and make use of that 6/8/10 speed transmission you…

Bet you can put an ecoboost V6 in one.

THIS is a well thought out response.

Kudos to you sir.

Show me a situation where the OCH/DOHC/ multivalve complexity is not outweighed by the benefits.

I see your point, but your supposition is flawed. OHC/DOHC engines make more torque per unit displacement than pushrod engines.

Could YOU be a little more arrogant? Your ignorance is consuming MY resources. I’ll even give you the fact that you NEED 420HP. Maybe you do, I don’t know. My point is that due to your inability to understand, you use more fuel than is necessary to make your 420 HP.

GM continues to make pushrod engines because they are…

you give me 2-4 extra gears in the transmission and I’ll drop a second or two off the 0-60 and still get the same mileage. Traction notwithstanding.

Your ignorance is appalling.

All other things being equal a multivalve, OHC/DOHC design will be make more torque and more horsepower and use less fuel than a pushrod engine.

Fact.

That’s exactly what I said. he didn’t print money fast enough by selling SUVs.

You can’t or shouldn’t at least have multivalve heads with pushrods. Four valve engines make more torque and horsepower per liter than pushrod engines all other things being equal. Pushrods fuck up your incoming intake charge, because the ports have to go around the pushrods. OHC and DOHC engines make more torque and…

No. Just No. Torque meanss you don’t have to shift as often to keep the engine cooking, but you still need gears to keep it efficient.

This is displacement centric thinking as dtailed above. Solve all your problems with huge, heavy engines. When your only tool is a hammer, all your problems start looking like nails.

Europeans won’t drive these pieces of shit.
