If you’re running 3000HP at 150PSI of boost or 30HP at 0PSI it doesn’t matter, you’re going to need to seal that combustion pressure inside the cylinder, however, the way you do this is going to be very different depending on those big, or small power levels.
Ryan Hunter of SCE Gaskets runs us through all of the essential pros and cons when it comes to the advantages of composite, Multi-Layer Steel (MLS), Vulcan Cut Ring and Copper O-ring head cylinder sealing gaskets covering all engine outputs from high output Top Fuel drag cars to your low output economy class street vehicles.
Also discussed is the potential ability to reuse MLS gaskets and what you need to pay careful attention to in order to do this safely, the way Viton coating is currently being used and the research around improving that and why a composite gasket will not cope with a high output, high compression engine and also interestingly why the head gasket for this task will not be reliable when it comes to coolant and oil sealing in a low output application.

Just for you @Trevor I'll do a community post on deck clearance shortly which is not quite the same topic, but you still might enjoy it. Should pop up here: kzfaq.infocommunity Deck Surface RA (roughness average) is as @Hammerhaus mentioned (cheers mate!) and is important in relation to your head gasket as if it is too smooth the gasket might slip/move on the surface potentially causing leak/s, and if it's too rough it might not seal correctly to start with leading to the same or other issues - Taz 👨🏻

Interesting how there is so much information and technology being required for the various gasket applications and there is no one size fits all here. Curious if anyone would run receiver grooves and copper o-ring and just ditch the gasket all together. Will probably need the steady hands of a skilled watch maker for receiver grooves for the coolant passages. Outstanding video Team HP Academy👏!

Another informative interview, always something to learn - it seemed the gentleman also enjoyed getting some informed questions, rather than the pap he probably gets on a regular basis. Good acknowledgement of the 'spring' that affects sealing - most people don't realise the head bolts/studs are basically very strong tension springs pulling the head against the block and compressing the gasket. With enough cylinder pressure there can be enough force exerted against those fasteners to weaken the gasket clamping force to the point where combustion gasses can escape - why we use stronger bolts, they won't stretch as much, maintaining the clamping force.

I'm not sure what copper spray you've had issues with but we've used this on a variety of different engine combinations and it does not affect the head. It's a pita to clean up on disassembly but only requires some time and brake clean or isopropyl alcohol and a rag. As covered in this video, there really isn't a 'best' solution.

This is something that's normally combined with the likes of a copper gasket (which does a terrible job on its own of sealing oil and water). SCE have their own solution with some of their copper gasket range as it has a rubber seal around the coolant/oil passages. The head gasket 'glues' won't really help your cause if you're lifting the head though.

So if I have a 300hp boosted Scion tc, the best one to go for would probably be MLS?

@duygukayhanisaskank4915 2 жыл бұрын

Hello Jeziel Perez, It's really up to you. If you plan to boost in excess of 16lbs, I strongly recommend their MLS. If you stay below 16lbs of boost, I recommend their Vulcan Cut-Ring. It would be very important to know your "final" compression ratio; with boost factored in. Such charts can be found on the internet. I researched & found SCE rates their Vulcan Cut-Ring Head Gasket with equal cylinder sealing strength as their coated MLS head gasket; up to 16lbs of boost. But their Vulcan Cut-Ring seems to have better head surface sealing for liquid-cooled heads. My Super-Charged, Big Block Chevy will never see 16lbs of boost. So, I chose Vulcan C.R. I have the cylinder seal strength I want & quality head sealing of their high-tech composite. Hopefully, this information is helpful to you. Respectfully, Ben

Could be one of a few things. 1.) You are not pushing/stressing your engine to the point it is an issue. 2.) Using products that give you a higher chance of failure give just that, a higher chance. There is no guarantee things will fall apart every single time at the exact same power level with the same issue, there is just the applicable probability of it happening, or not. 3.) Regarding point 2, yes, you may just have been lucky so far depending on other factors. You might never have an issue for the life of the engine, it might let go tomorrow. Basically it is not always just black and white, do this it fails, do this it works, but more what you do and don't do to give you the best chance of producing solid power from your chosen setup reliably - Taz.

@hpa101 2 жыл бұрын

There isn't a hard and fast rule, it depends on the engine and what you are doing with it as simply having a turbocharger fitted doesn't really mean a whole lot as a piece of information by itself. Get your details together and talk to your head gasket supplier and engine builder if you're using one etc would be my advice. They might have questions that make you realize you still have a lot of other things to work out and consider before you even get to this point. If you are learning to build your own engine via our course material this is discussed and it is something we can help you with via the members only forum too, however, I wouldn't sign up just for this question or if you don't plan to do some of the work yourself as that is where the value comes from with HPA - Taz. www.hpacademy.com/free-engine-building-lesson/? www.hpacademy.com/hpa-engine-building-starter-package/?
