Do you all think a block guard is necessary/good idea/not needed on a y8, stock internals running 10psi?

 

Honestly, no. Unless you have a machine shop install it and drill the holes out bigger to allow more cooling, I'd say save the $100 or whatever they cost. Blockguards tend to be restictive and don't allow the water jackets to flow the way they should. At 10 psi your cylinder walls aren't going to be moving the way they would at say 20 psi. So I say stay away from block guards.

 

No........don't do it.

Thank for you opionion

More would be appreciated as well

 

So let me guess, you are waiting for someone to tell you they are good and you should get one or what?


I'll break it down for you.

Your stock rods will snap in half and shoot out of the side of your block at around ~225hp. Your stock pistons will melt at around the same point. Now, your cylinders are still ok. Do you think it would be a good idea to reinforce the strongest link or the weakest link? The sleeves will hold alot more than your stock pistons/rods will. Even if you were at the breaking point of the cylinders, do you think it would be a good idea to rely on a cheap piece of aluminum that has no specific engineering involved and only protects 1/2 inch of your cylinders to save you motor from grenading?

Let's also factor in the restriction in the cooling system. You have just placed a large obstruction directly in the path of the coolant passges which were specifically designed to reduce the heat of your motor, which is the thing you were "trying" to protect when you installed your blockguard.

If you are producing so much power that you need something like this, I would seriously suggest another form of reinforcement. I would also suggest upgrading the pistons/rods before even thinking about cylinder walls.

Just my $0.02

No No No,

I wasn't trying to be a smartass, I was letting you know that I apreciated your opionion and was curious to see what others had to say.

I too believe they are a waste, but I wanted to see what you all had to say, so I asked.

Thanks again,

 

Oh, ok. Sorry, I get touchy about the subject.

Blockguards killed my baby.
