Re: Double block guards
STR's were well engineered and the only ones I have ever seen with thought behind them. The proper installation of a open deck girdle would be a interference PF of at least .0005", recessed from the deck face and machine the bores accordingly....Oh yes I will add the IMO for argument sake.

Re: Double block guards
I felt the need to respond to this.
The same thing any girdle, gusset or casting web does.
At the top in an attempt to help defy deflection from increased pressures or to help hold concentricity between the axis centers. Which ever definition you prefer.
Sure it does, if it's installed correctly(to a point). So do full sleeves, but they actually take up more surface area and tend to create more surface tension at the faces. If you have extreme cylinder pressures, the wall thickness is your weakness, won't help I agree.
IMO a top girdle would be acceptable, provided installed correctly and machined after as stated, for mild builds or nitrous cars as a measure of insurance from cylinder wall deflection on any open deck design. It's obviously an outdated practice with little relevence in the world of FI but they have a intended purpose.
ON EDIT: 2 of them would be rediculous.
I never believed in block guards. What are block guards used for?
To help hold the cylinder in place from extreme pressures, etc?
A block guard is not solid and doesnt necessarily HOLD the cylinders equally. For one, it actually takes up space up at the top where water should be cooling the cylinders. Another thing is that if there is detonation anything like that. A block guard wouldnt do anything to protect the cylinder wall itself. That stock cyl wall is going to crack regardless if there is a block guard or not.
I've seen some people bring in block guards that arent even equally machined. Some parts of the thing is snug against the cylinder wall and the other areas arent even touching. So hows that suppose to hold the cylinder walls well.
Thats why if youre not in the level of needing Iron Ductile Sleeves, I would just use a stock block with no block guard. If you feel youre at a level where you have to strengten your block, its probably at a HP level where you need to sleeve anyways.
Not going against anyone here, just stating my opinion. Everyones entitled to their own.

Re: Double block guards
Care to elaborate? Jw. I know its a "old School" thing. But 10+ high hp honda's in my area including myself have the same Block posted setup and it works great. I know it isn't done by alot of people though.

Re: Double block guards
Wow, 07' and with a whopping 125 posts which I would normally not pay attention to but with you it shows........
You're lucky this is the "new honda-tech" or you woulda been burnt worse than a hooker with a bad outbreak by numerous regulars on here. You have taken what golden eagle stated personally because you are insecure/nescient. If you understood what he meant you would have just kept your mouth shut and taken it with a grain but you get feelings so you degrade him and his company. Are you really 35? I have my doubts. A modicum of wisdom usually comes with 35 years of life. Next time just be quiet like a good little boy and you might learn something. This country has PLENTY of loud mouthed ignorant punks. Be a rebel, don't conform.
BTW, Helen Keller from 5 ft away could tell that block guard is almost flush with the seating surface..........you MIGHT have 1/8" of clearance and that would be a liberal estimate on my part.

What do you consider high HP? If you consider your 420hp civic high HP, then that is a good amount of power for stock sleeves but I've seen 600-700 on stock sleeves.
If your sleeves are gonna crack or anything at all a block guard is not gonna stop it. It will help contain it but not prevent it.

Re: Double block guards
I agree with what most have stated. Block guards have not really been proven to do a great deal. With the power that can be made w/o a block guard and with stock sleeves why even use a block guard? If you want crazy power you will need to sleeve it anyway. Most install the block guards incorrectly like the guy above (to close to the sealing surface/cooling surface) and do not get the block honed AFTER installation which causes even more problems than the block guard solved. Don't waste your time. You will be good with a competant tuner.

Re: Double block guards
Firstly I apologize to the OP for this...........
Something you expect from someone on the other side of the country? Ok, that makes a whole lot of sense. The 07' and 126 (now) posts that you currently have CAN be used to ascertain whether or not you know what you are talking about. In this case your knowledge/wisdom/maturity is directly equivalent to your post count or more accurately lack thereof. It seems you have forgotten that YOU are the one who originally went off topic with your banter/prattle/nonsense.
So I need to attach a picture otherwise anything I post is moot? Interesting theory there guy. And no, I don't take this all that seriously. I just find it a bit annoying year after year when people spread misinformation like a case of SARS. It is good practice whether or not people enjoy it to sometimes correct incorrect actions.
I find it amusing that you feebly attempt to bash people publicly who likely have many more years and much more exp than you and then tell them to PM you as their information/posts are irrelevant. Interesting that you find it acceptable to bash people in public but then tell others to respond in private. Talk about speaking from behind the mask. -_-
Enjoy your life, falacious theories and numerous hypocracies. I'm done with you.............
And yes I'm sure I misspelled words but I'm too lazy for spell check right now.......
BWahahaha, I spend more time working on cars then posting on HT, I expect this from someone thats on the other side of the country, I never post on something that I cant relate too, thus 125 posts and wtf does that have to do with anything anyway, put some pictures up and give some relevant information chump. Am I really 35, yes, and insecure people don't shooot their mouth off as well as me. I sent you a friendship request, get back to me. LOL, you take this too seriously,
