Ok i have read and done alot of research on the block guard, but whats it Pro and what are the cons??? some say they wapr the sleeves some say there perfect, so what are they Pro and Cons???

 

do a search, this has been covered more times than i know of.

 

what up dude?

My personal $.02 would be don't get it. To put it in right it costs some $$, it would be more worth it and safer in the long run to save for sleeves. Or keep your power goals low.

 

con: the extra metal to metal contact around the top of the sleeve with the block guard will cause hotspots.

 

With good fuel management and tunning you will be fine. I think block guards are useless and I would never get one. If you did search this forum you would have found a butt load of information on block guards.

 

yah and when your searching remember to click the archived

"Blockgaurd" all you need to search for in the arhived forum. You will get enough threads to last you all night.

 

Yea i have searched but noone really says why there so bad??

 

great thread

 

i personally dont like em and here is why.

the main enemy of an internal combustion engine is heat. A blockgaurd will succeed in stopping coolant from getting to the top of the collant passages.


thats why i dont like em. the cons outweigh the pro's IMHO..

What are you talking about? Type in block guard, blockguard, block guards, blockguards then search recent and archived. I know I have did it before so I know the info your looking for is there. You will find hundreds of posts and if you read a few of them you should find everything you need.

So closing the deck like those who has their blocks sleeved is also a bad thing ?

they shouldnt (a decent designed bg) block it anymore than a normal sleeved engine would, braced or closed deck . . . st00pid uses em and he's having pretty good luck with him judging by the some of the nasty cars that his fingers have tuned. Sleeved would be ideal obviously, but so long as it doesnt take a sledgehammer to install it and it fits, I dont see any problems to running one. and to the guy that said they cost a lot to install . . . its not rocket science do it yourself.

That's how you warp cylinders.... you have to bore and hone, etc after installation. Go ahead and tap it in if you want, but it will just cause problems. Instead of buying a block guard and paying for installation spend the money on tuning. If you get to a point where your worried about the cylinders have the block sleeved. If you just have to have extra protection then post the block.

Never had a problem with overheating or anything of that nature. This was just my experience with blockguards. Both times I used STR which allows more coolant to flow than some of the others I've seen. I just got it for added security to keep my cylinders from flexing under high boost. It held out and then I just sleeved the block for more of a piece of mind.

 

Ummm yeah I could be going out on a limp here, but I bet 90% of all qualified engine builders dont hone or bore cylinders after a bg install (I know that most qualified engine builders would probably have a sleeved engine but for those that deal with bg's). If you tap it in and make sure it isnt a tight fit, I wouldnt worry about it at all. Everyone knows its better to spend money on tuning and obviously its better to have a sleeved engine than a block guarded one, but truth of the matter is we're not all Bill Gates so not everyone can be expected to pick of a Benson block all the time.

 

Why do people believe that blockguards can somehow "warp" cylinders. I've never heard of an actual case of this happening, with real proof. I could be wrong here buuuuut, how is something like a block guard, going to be able and somehow warp the cylinders when in place, when people have taken the stock sleeves themselves to 400-500 hp without "warping" the cylinders. If that much heat in the cylinder/pressure isn't doing any damage, how is having a block guard in place going to somehow cause more damage? I'm seriously lost here, so if someone could at least provide some proof along with their argument, it would help me a lot.

BTW, I've never had problems with mine in my d16.

EDIT: I'm talking about a correctly installed blockguard. If people are pounding their's into place, that sounds like more of a likely reason to cause warping then if the blockguard is in place correctly. Mine slid right into place with no pounding. I just searched under blockguards and I'm seeing cases where people literally hammered it into place and wonder why their sleeves are now warped. Hmpf!

You don't need to be bill gates to post your block...

 

okay there was a hint of sarcasm there. I dont know enough about posting to qoute prices on it or praise it. But you're doggin blockguards like there the worst thing since Barbra Streisand, when there are quite a few people using them succesfully.

 

i dont get why the bg would cause hot spots???? because by adding the bg there is more surface area therefore longer too heat up and the heat should get disapated into the coolant?????? thats what i think

 

i think as long as the block guard isnt forced in to make fit than warpage will not be a problem... if its too tight sand the guard down till you can just slip it in... you can even use a depth micrometer to check that it is level... boring and honing the cyclinder will not do anything to aid the block guard fit cause the block guard contacts the outside of the walls and if improperly installed will still warp cyclinder walls if guard is not level... i do not have a block guard or install one yet but will be on my new setup... just info that i understanding from reaserching and brainstorming...

 

I know of a Z6, 280whp, w/a block gaurd, dayly driven for 2years without ANY problems (overheating, warping, or otherwise)

I know it was properly installed though

 

all the block guards i put in have alot of play
u dont need to tap it in (u must have a defective one) on my own motor i had the machine shop weld the bg to the cylinders and block then deck it .
i ran this ls vtec motor first with a supercharge with direct port nitrous and now i have a drag turbo kit with upgrads and it s still running strong. o and its a daily driver!
stoopid from hondaswaps ran a bg on a ls block with all stock internals and made about 298hp to the wheels!

 

I recommend a block guard. Just make sure that you drill out the holes to match the head gasket. I just put it in my car after the bottom end was already assembled. Held up to 26 PSI for the whoel season. I also used them in my single cam and it saved my parts when I split a sleeve. Brian

 

cool guys, I was starting to think I was the only one that wasnt anti BG
