Re: H22 Blockguard enough to run 15psi daily? (jdmhonda)
psi doesn't matter...how much hp matters. yeah you could probably run 15lbs on a t25. yet again I just saw some eg with like 420 some hp on a stock block...
I hate to say it but use the search button

Yeah I bet it really doesn't matter. There is no difference between 1psi and 45psi. -Use common sense. Why would horsepower numbers matter more than the amount of air being crammed into the cylinder-which is what causes the extra stress on the motor. Horsepower is just a measurement(a number) it is a by product of the boost psi and compression ratio. Do you have any common sense?

Re: (one4darkstar)
it's high cylinder pressures that break things. this pressure is caused by burning fuel. when you burn lots of fuel, you make lots of horsepower. You can run lots of boost and still have relatively low cylinder pressures if things are not set up right. This is why people running little turbos at high boost don't make much power.
h22 ring lands (and sleeves) break because of detonation. the ring lands are weak and the motors have high static CRs. they ping, and the pistons break. enough of this, and the sleeves crack too.

horsepower is a measure of the ability of an engine to do work.
it is not a "by product of the boost psi and compression ratio".

So you are saying that the amount of compression and the amount of psi dont affect horsepower output.
A short definition of by product-things that help make up something else. Ease of airflow in and out of the engine,compression ratio,air/fuel mix, and psi(if it's boosted) are all by products of horsepower B

Lots of things affect potential engine horsepower output.
But saying stuff like "Horsepower is just a measurement(a number) it is a by product of the boost psi and compression ratio." really makes you sound like a moron.

Re: (one4darkstar)
aha, that first ditty is totally sigworthy 
Considering your stock sleeves take 1000+ PSI of force under power, and even a high compression N/A motor is seeing 220-250 PSI cranking, no, 1 psi or 45 psi doesn't make jack **** of a difference in how long your motor will last.

The largest problem is that you don't really know what you are talking about.
Horsepower output has a whole more to do with RPM and torque at speed than anything else.
Either way, it's not the pressure of the compressed air (the oxidizer/catalyst) that causes broken motors. It's cylinder pressure. H22s die from detonation, not high boost.

Re: (dustin)
Granite, I am a new member myself....but seeing as Dustin has 12,000+ posts and one4darkstar has 11....I would have to say that isn't exactly a great way to say hi to the veterans on here haha. Not saying anything against you man...it was just my observation when I read the thread.

Re: (Dunc)
which h22 do you have? from what year? because the h22a's are closed deck and you cant run a block gaurd. where as the h22a4's are open deck and you can run a block guard. even though it will be useless because i'm willing to bet my left nut that the ringlands will blow before you break a sleeve.
and to add to dustin's argument, psi makes no difference. it's horsepower. think about it.... is 15psi on a t25 the same as 15lbs on a t88?

This is correct. You would have to have an awesome tuner to basically tune everything on the h22. Nothing is impossible with a good tune but I'd go standalone if you plan on doing this. I've seen high boost on stock h22's but not 15psi daily. The ringlands will go pretty much. If you really want to run like 15psi daily, I suggest you look into sleeving your motor and dropping forged internals into it. Cheap, fast, reliable (pick two, the other one left is not). My .02

I thought this way myself until i blew my motor. I cracked 2 sleeves all the way down the entire cylinder, my wastegate line broke and the boost spiked to 20+psi with no damage to the pistons and rings at all, i couldnt believe it. This was on a b16 but i thought it was amazing anyways since most stock motors usually crack a ringland before anything.

Re: (Pikachu)
Yeah the #2 cylinder is cracked just like the one in the pic. Here is a video if i can get it to work.
http://www.sportsnimports.com/...7.MPG
The blue car in the video runs low 11's high 10's to give you an idea on how fast it was before it blew.

You wouldnt have to sleeve it though to be reliable. As long as you correctly install the blockgaurd and put good internals in it youll be fine (with a good tune). I would tune it to 400 hp and be done with it, once you try to get more than that is when stuff starts to go wrong unless you have plenty of money to spend.
