It's not shit, the intake is very restrictive. If you move the carb up a bit it makes plenty.

>For four grand, our 512-cube Cad pumped out 514 hp at 4,400 rpm on the dyno. Torque? Try a healthy 575 lb-ft at 2,600 rpm on for size, buster. Whether in a De Ville or a Chevelle, that translates to streetable, repeatable low-12/high-11 quarter-mile times. With uncommon class.

>10+ years of engine development between them with added exhaust VANOS (variable valve timing), Valvetronic (variable lift), 3 stage DISA (variable intake) for 10hp/liter more
I would say torque/liter for petrols is more important

Yes, these vehicles can be purchased by regular people and be used for personal transportation, but that’s not their primary purpose, is it? Trucks like the ram 2500 are primarily designed for commercial and fleet use (transportation of goods, towing, construction site duties, etc.), which is why they are often exempt from EPA testing. While they are certainly capable of serving as personal vehicles, they are engineered to different standards due to their purpose. Japanese manufacturers like hino, fuso, and isuzu have produced commercial vehicles that can exceed a million kilometers/miles, which is considered high mileage. Just because there isn't a picture of one online with exactly 1.7 million miles, doesn't mean they can't do it. The reason why i posted the old man with his 1993 corolla (which made you seethe really badly), is because it’s more remarkable for an cheap econobox to achieve such high mileage compared to a expensive 1/2 ton or 3/4 ton truck (like the ram 2500), which was designed for much heavier workloads/last longer. You can continue to post you sex tool engine maker all you like, because you won't find a similar class american econobox with similar mileage. As for the kenworth you posted, that's a heavy duty truck designed for industrial use. You really gonna compare that to a bus engine. Is that even the original engine with no rebuilt? The volvo engine, literally had no noticeable wear after 2+ million miles, it probably would of done another 2+ million or more. Overall there is no reason to continue this conversion.

They look up to whites, they respect whites, they emulate whites, but they don't try to pretend that they are white.

literally no NA engines make +100 hp/l stock

NA engines do around 75-80/l
Turbos push it to 150-160/l

Anything above risks catastrophic failure. At a certain point, there is no replacement for displacement.

I absolutely love the sound of my old 4 cylinder shitbox with rusty exhaust and a failed muffler. It roars like a lion and its pretty much as good as a petrol 4 cylinder can sound. How do I replicate that sound but with a brand new exhaust?

they get a home turf buff like in an RPG

Let's play a game, /o/.

Describe the Engine in your Car in such a way that someone could guess what Engine it is. Ask questions about the Engine or the Powertrain, but you can't directly ask what Car it's in. Goal is correctly guessing a specific Engine Code. We'll call it "Motor Charades".

I'll start.

Features:

It's an All-Aluminum Foam Cast Long Block, Bore x Stroke Ratio is Undersquare, it has 10.0:1 Compression, Multiport Fuel Injection, DOHC, 16 Valves, VVT Cams, a Muffled Intake, a Choked Exhaust, Redline around 6300.

Despite that, it makes just enough power to get out of it's own way, probably due to various improvements it inherited from it's bigger, younger brother.

155 hp @6100, 150 lb-ft @4900. Don't let the 2nd Torque number fool you though, it's beefy down low. VVT has its benefits.

2 Timing Chains to be found here. One for the Cams, another for the Water Pump and 2 balance shafts.

has to be ecotec, probably the 2.2 as the regular 2.0 had less hp if I'm not mistaken
>>
>>27985977
Yessir you got it.

Though there were no "regular" 2.0s, every ecotec 2.0 was either supercharged or turbocharged.

My eco 2.2 is a later variant (LAP) with VVT, see. It picks up a couple hp over the older 2.2 (L61).
