Has anyone here EVER had good results with a blockguard?
 

Have ya?

Re:Has anyone here EVER had good results with a blockguard?
 

i guess i can say YES...due to the fact that people ether HAVE the heating problem or they DONT. but i'd rather have ductile iron sleeves put in or if not at the worse...studs to reinforce the critically acclaimed floating sleeves.

Re:Has anyone here EVER had good results with a blockguard?
 

I've seen one company that makes the blockguard with very large coolant passages which is supposed to work well. Time to do some research.

AZRace and STR have the similiar design. Definetly better than the one on the bottom.

I used the one on the bottom. I'd like to get ahold of the bitch that designed that piece of ----. Nothing but problems.........I'd hate to say it, but I'm pretty sure it was made by AZrace. :-\ That's what they said anyways. >:(

what holds the blockguard in place? is it just a tight fit? do you HAVE to have the bores aligned and honed after installing?

Re:Has anyone here EVER had good results with a blockguard?
 

i think its a tight fit but you can also get them welded in.

Dave from dh-racing ran 9's on stock slevved b16 block w a welded in blockguard for a whole season so they work.

some people have good luck with them most don't

Re:Has anyone here EVER had good results with a blockguard?
 

welded in, then bored, seems like the only problem would be possible overheating on the street i guess

Re:Has anyone here EVER had good results with a blockguard?
 

Can someone explain to me why these are considered so bad, when nearly every other motor is a closed deck design (including H22's if I'm correct). Isn't the block guard, if properly installed, simply imitating the effect of having a closed deck block?

Re:Has anyone here EVER had good results with a blockguard?
 

A closed deck block was designed to be a closed deck block. An open deck block was designed to be an open deck block. The blockguard slows coolant flow, distorts cylinders, and creates "hot spots". If it is properly installed(welded, bored,...)and the coolant passages are large enough to allow proper cooling I would say it might not have a problem, but at the same time I don't think this piece of ---- is going to stop your sleeves from cracking. It's a cheap fix/hack to "try" and prevent the sleeves from cracking. Maybe it's just me, but if my sleeve is at the point to where a piece of aluminum might prevent it from grenading, I might need to consider a more permanent solution to the problem. :-\

Dr. Boost, I think that's the most well thought out explanation I have ever heard. That's better than "They suck, and people who use them are gay." ;D

Re:Has anyone here EVER had good results with a blockguard?
 

Haha, that's funny because I have probably used that explanation before as well. ;D

<<<<<not a big fan of blockguards. :-\
