Awesome video D4A! I assumed sleeving was required on open deck engines but you make a good point about ECU tuning. 20 years ago, most tuning was done using "piggy-back" ECU's or rising rate FPRs which had zero knock control. I remember tuning my JR supercharged Miata and the instructions were to advance timing until there was audible detonation and then pull back 2 degrees. On hot days I could still hear it ping once in a while which was absolutely nerve racking. Again, awesome video and I love the editing :D

open deck crank cases are traditionally a much more demanding job for the cylinder head gasked. The modern MLS gaskets also helped the open block design a lot. Open deck can be casted as dye casting (without water cores) which is very cost effective, this is the main driving force behind it (and better cooling).

Piston design and materials have allowed for a larger margin of error, too. Thicker ringlands, better forgings, and higher quality materials make surviving an ignition, boost or less than "as advertised" octane fuel problem, better in recent years. However, it is usually the human factor that destroys an engine. The desire for better track times or beating a competitor leads to higher boost levels until you find the limitations of your engine. It is called, "The Human Condition." As competitors, we like to "ride the edge." That is what makes life interesting!

Modern engines have developed quite a bit since the 90s and early 2000s. Look at head flow for example, I have a 1999 dodge dakota RT. Factory head flow is very low, somewhere around 150 cfm. (Just going off engines i know) The late 2000s dodge 392 scat pack hemi has head flow over 270 cfm. Not entirely sure what it was but that kind of head flow on my old 1999 dodge would make it a completely different animal. The last generation of vipers were pushing 340 cfm which is just bonkers to think of. Head flow will in turn make more power when boosted compared to the same head flowing less

Mostly because in all honesty it would be very hard to draw a half-decent general conclusion, as it actually varies between individual blocks mostly based on block architecture, water pump and the rest of the cooling system design, with deck design playing second fiddle. You can find plenty of closed deck blocks that manage better cooling than open deck ones, thanks to clever design. In retrospective, I shouldn't have mentioned cooling in the beginning of the video.

I believe that some Gardner diesel engines had no cooling passages between the head and block. There was separate external plumbing to carry coolant to and from the block and the head. There were passages to allow oil to drain from the rocker area back to the sump. I believe that this design originated from these engines being originally designed for marine use. They had a reputation for extreme reliability but this probably results from over-engineering and relatively low specific power output. But they had REALLY closed engine block decks.

One thing I do remember is that the blend of silicon in the alloy makes a big difference to the overall strength. Also as mentioned, considerable improvements have been made in casting techniques which, while not increasing the strength of the raw material its self, does give you stronger components by eliminating air pockets and oxide layers within the parts. This, in combination with advances in CAD design means modern aluminium blocks can be made not only stronger than their ancestors, but lighter too.

@@soundseeker63k, so it's not an issue of open vs closed, it's an issue of poor manufacturing quality. Even so, the poor quality applied evenly to every engine, which design do you think will fail first? That's right, the open deck design. This might just be me but in a passenger car meant to transport and no racing application, I want a more moderate displacement naturally aspirated engine. 2.2 liter-ish. But nooooooo, manufacturers are trying to save weight so engines are made smaller and fitted with turbochargers that I don't intend to pay for because I DON'T want one, to compensate for decreased power that comes with less displacement. Ok, I thought fuel economy and emissions was the priority and turbochargers are at odds with that end goal but, ehhh, whatever. The point being that whether it's iron or aluminum, closed or open, for GOD'S SAKE if the manufactures are going to produce power dense small displacement engines with boost pressure then MAKE THAT DAMN ENGINE PROPERLY! Make it strong to handle the heat and pressure. But they don't, as evident by numerous lemon law lawsuits. Well damn, if the manufactures are trying to produce these smaller engines with as little cost as they can while still maintaining desirable power output, then they should choose the stronger AND coincidentally CHEAPER material, IRON! The EPA and FTC is also complicit in this since emissions are talked about as if it were some great threat to national security or some other nonsense and worse yet emissions regulations seems to be the ONE thing that is allowed to supercede consumer protection.

There is also the issue of long term reliability. Dealing with a lot of open deck engines (Mostly Volvo Modular N and RN series) the main killer long term is cylinder oscillation, even with a MLS head gasket, they vibrate during opperation due to the latteral forces caused by rod-angle. So they fatigue. Typically inserting and welding in small supports to make it semi-closed makes a big difference, and inserting a block guard makes them hold up ALOT. For more extreme cases we use the "D5" block (Diesel variant of the "T5" block) and insert and weld a deck guard, then the block is good for 200Nm per cylinder.

You didn’t really explain why car companies use an open deck block. What are the advantages? You just said it’s not as weak as we think.

The problem with open deck blocks are keeping head gaskets to seal at higher power levels even stock power. you guys know what brands and engines😐
