Did not dyno only street tune and I ran on 16psi for over two years now. No blockgaurd. So yes I can say from real life experience It's not needed. I think a block gaurd gives a false sense of security

If you want a strong block go sleeve's. Do it all or nothing, cause I know way to many people run without them including myself with no problems

I believe using a block gaurd keeps the sleeves in one piece in the event that it cracks.Better to crack than have chunks going in the cylinder because no block guard was installed.</TD></TR></TABLE>
Sorry but I've seen sleeve's cracked into chunks with blockgaurds. I don't think that matters anyway because the whole point is for your sleeve's not to crack. Right??

 

Ive always thought that the cracking that occurs in most open deck blocks was caused by the materials used to build it, overheating or detonation. How does a block guard solve any of these problems?

That is what I always thought

And just look around at the amount of people with D-series complaining that they blew a headgasket. How do we know that a blockguard wouldn't have stopped the sleeve shifting that caused the headgaskets to blow?


Actually, now this seems like an issue that can't be resolved. I mean, how can you tell whether or not an installed blockguard is helping, or whether a blown motor would have benefitted from one?
