Yes im well aware of that but as an engineer, you can see what potential weaknesses are as a result of a change, and do something to adres them accordingly. My question is around the thinning of the cylinder walls and their ability to cope with the increased frictional heat.
What I didn not ask is how long it will lass (not quantifiable without testing) which you have presumed I have asked.

Increased combustion heat I can see- you're making more power.Is a larger displacement motor somehow creating more friction simply by being larger?
I understand there is more surface area, but that would mean big V-8's have 2-3x's the possible frictional heat based on displacement.I also understand that less sleeve/material has less dissipating capabilities.

Piston now has a higher travel, or total stroke, therefore the piston speeds are much greater at a given engine RPM, esp at 9000.
That combined with a thinner cylinder wall, and you might have a problem.

There is a thinner cylinder wall but the material used when sleeving the block is a lot more stronger/sturdy then the stock walls. I could see head gasket issues come up before cylinder walls cracking or sinking.

you could possibly run 50/50 Water/Meth injection on regular 93 octane street gas which is like running 110 octane race fuel all the time and street this setup without the issue of $7/gal fuel

What do you think my limits would be as far as psi that I could run with a ems and bigger injectors? I recently melted a piston and got my motor sleeved by jim justice. I bought carrillo rods and cp pistons and kept the compression at stock but with a much beefier internal setup. Also got the head totally rebuilt with new seats/seals and got a valve job, So its pretty much a totally fresh built motor. I would think that with it being sleeved it could take quite a bit.
