I mean, all the other manufacturers switched to tt 4L v8s - uniformly, there's probably a reason for that

I get 28 mph in my compact crossover :) on the highway

>>28897754
pushrods are bad because they prevent horsepower and torque and I think lower the overall compression ratio because you have to fit the pushrod plumbing next to the block instead of up on the heads (not an expert tho), but I mean they have been phased out and are associated with older engines for a reason

its weird, its like you shilling carburation instead of fuel injection
you are glazing chevy for being cheap and lazy
the corvette should have a twin cam 4l turbo STANDARD with a larger engine the upgrade
can you explain why the zr1 has been twin cam since 1990?
>>
>>28897765
because 0.5L per cylinder is a good compromise in terms of power/weight/efficiency
it also lets you design your engines modularly to save on manufacturing costs
thats it, thats the whole reason

And you expect me to take you seriously?
>I'm no expert but I'm going to spew delusional tiktok tier nonsense as a way to appear smart
>Those pushrods? Heh, yeah those lose torque and horsepower
Meanwhile in the real world: That pushrod vette has the most torque of ANY N/A V8
Pushrods were phased out because of strict emissions regulations. Not due to hitting a performance ceiling. There's a variety of ways to build an engine, the key advantage to a pushrod setup is how simple it is as a whole (which is ultimately pro-consumer thanks to its simplicity)

If you think giving credit where credit is due is "glazing" then sorry chuddy but you're just a shitty human being kek.

>>
>>28897817
That was my 1st post in this thread.
Idc about gas mileage. DOHC (esp with cam phasers) allows for higher redline and different lift profiles at the top and bottom end of the rev range so the whole range isn't a compromise.
It allows for higher redlines and gearing advantages. It was designed to get around displacement tax, but it does work and is better 99% of the time.
Some nitromethane engine that costs 5 figures and lasts literally seconds isn't saying much. Similar "argument" as the maccas guys you rage at who post rally winners with maccas.

Still makes more sense than Porsche's naming scheme.

>>
>>28897843
No one is putting a top-fuel engine in their street car, don't be silly.
OHC / DOHC was designed specifically so you could accelerate the same with a smaller engine as a bigger engine can while also cheating emissions / fuel regs. Adding it to a gigantic engine will still provide benefit. Whether that's cost-effective to a race team is another thing.

>>
>>28897853

DOHC engines are the good enough compromise
>>
>>28897823
There are ~11 liter big block Hemi V8's making well over 5500hp on a hub dyno that are capable of holding together for an entire season of racing. Where are the DOHC engines with numbers like that?
>>
>>28897861
DOHC is more-complicated. It's cheaper and easier for a racing team to run and maintain a gigantic pushrod engine. I like that sort of thing too, but it doesn't mean it's "better," nobody makes 11L DOHCs to compare it to (likely for the reasons I stated above).
>>
>>28897861
how much gas does that use?
spaceships go really fast anon
>>
>>28897863
Cost is irrelevant in the semi-pro to pro racing world. They're going to use whatever's faster. If DOHC V8's were truly better people would be using them more. Sure the Coyote is impressive but it won't be replacing big bocks anytime soon.

>>28897866
>how much gas does that use?
The guys doing drag week get anywhere from 10-20mpg highway. inb4 that's bad. It's a street legal 6 second car...
>>
>>28897875
Sounds like a lot of cope.
DOHC literally gives smaller engines an advantage. Adding it to a huge engine would provide similar benefit.
Also, race engines are always in their powerband, they can be lift/advance timed for the peak and only the peak. A street engine is usually not above 5k rpm and DOHC allows such engines to be driveable while also accelerating as well as larger engines. Apples and oranges.

Mercury Marine makes a 7L DOHC LS for street vehicles. The power numbers are not that impressive for all the added complexity. It's the size of a big block pushrod V8 that can make the same power on pump gas with a perfectly drivable powerband.

Cruise ships each burn 80,000-100,000 gallons of crude a day and serve no purpose.
Airplanes don't have emissions controls.
Fossil fuels are the main source of electricity that powers EVERYTHING around you, and no one bats an eye.
40-70% obesity and farming is a huge source of emissions but no, ignore that, it's body positivity. Think of all those refrigerated trucks and store refrigerators just there to sell garbage food which only 1/3rd of will be eaten, and all the fertilizers, there's just so much off that one thing you could focus on.
But cars?! NO oh no no, they are the source of pollution even though they have crazy levels of emissions controls.
Get bent.

>>28897894
It's pretty cut and dry when it comes to pushrods being superior. Until a DOHC runs a 3 second 1/4 or holds a land speed record that will continue to be.

>>28897920
I agree with all those things. I love sports cars, I've been racing for decades, but I don't think my impact on pollution has been large. Overall I think I'm in the bottom-20% of Americans on overall pollution. It'd be nice if we had recycling here, but you can't even pay for it.
>>
>>28897929
I never suggested sports cars are a big part of the pollution puzzle, but they are undoubtedly far less efficient than other cars and are largely bought by boomers to show off and be wasteful and a lot of people buy them to drive in unsafe ways that threaten others. Having had people tailgating me often enough, I just don't like fast cars.
>>
>>28897932
Lots of things cause pollution just for "fun." Sammy down the street with his Funko Pop? That was synthesized out of crude, extruded with great energy, and shipped across the entire world. For what? There's got to be a reasonable balance, you can't just say "I don't like X" and expect it to be banned.
>Having had people tailgating me often enough, I just don't like fast cars.
Have you considered staying out of the passing lane or not being a little whiny bitch? Everyone gets tailgated sometimes, and it's usually not by sports cars. If you're tailgated often, it's because of something you do.

>But it's more expensi-
Exactly. There you go.

>prevent horsepower and torque
Kek. Top Fuel dragsters that make upwards of 10,000 lb-ft of torque use pushrod hemi V8 engines. Show me a naturally aspirated production V8 that makes more torque than the LS6.
>lower the overall compression ratio
LS6 has a compression ratio of 13.0:1
>twin cam 4l turbo STANDARD
That's gay as fuck and retarded. Pushrods are advantageous because they make more power in a smaller size form and the simplicity drives cost down. That's the reason why they can fit so much power into such a small size chassis as the Corvette or Viper which also uses a pushrod design. The whole "LS swap it" meme started partly because you can fit an LS motor into anything, even a Miata, thanks to the pushrod design. Good luck getting a Coyote in there.

Those Viper pushrod engines can be modded for insane power too.

https://www.youtube.com/watch?v=JvOR0QXFQUw

There is no replacement for displacement and pushrod engines are optimal for chasing massive amounts of displacement. Plus they sound better with a nice deep traditional sound versus the raspy ear rape of DOHC V8s. Flat plane V8s kind of fix that issue though.

>>28897750
What's ironic is that actually the high displacement naturally aspirated pushrod engine gets better fuel economy. Why is that? Pushrod engines are smaller and lighter. This allows them to be placed in small, lightweight, highly aerodynamic cars. Combined with cylinder deactivation and V4 mode, they actually get better fuel economy. All those TT 4.0L DOHC V8 engines are put in massive heavier cars, SUV/CUVs. They get more worse fuel economy than the light and nimble Vette. Simplicity wins the day.
