Did you decide to leave part of the supports out? By doing so, you are kind of defeating the purpose of the block guard since it really only ever cracks in the area you left out...

Also, it won't be the boost and/or power that will break and crack the block. It will be detonation if at that boost/power level if it ever happens.

What fuel are you going to be testing with?

Hopefully pump 93.


Also, I am happy a shop with the tools and $$$ are willing to try this out. Even bigger balls and respect is showing us their RD work up front upon request and interest. Very few shops do this and it's always admirable when they do.

Point being let them try and see where it goes. If it fails, hopefully they'll let us see the nice cracks

From the pictures posted, it’s unclear what sets our design apart from what has already been done. To clarify, what you don’t see in the pictures are the 4 removable plugs that go in the open cavities over the case bolts. These plugs are a mild interference fit, that will support the cylinder, and mitigate the integrity issues that have been mentioned.

At this time, these pictures and parts are literally hours old. As more progress is made, pictures will be posted to show what I am talking about.

Brian, glad to see a plug for the open cavities. Any idea of the level of cylinder distortion from popping the plugs in last minute?

What type of aluminium are you using as "guards". Did you give it any heat treatment before decking?
I think that your desing is not going to do the trick. It`s a good idea but im a bit skeptic about those separate blocks preventing a crack in a cylinder.

The first product block, still in the machine. =)



We are putting together a complete write up of what we are doing and what materials are being used. I'll have it up soon.

Thanks, guys,.

Looks good. I like how you added a piece to support the part of the block that actually fails.

Here is my question. Is that piece pressed in then decked? Does that mean you guys have to assemble and deck the motor after? If so, the cleaning must be a pain I would think.

If not, does that piece remove easily? If so, that could produce a serious head gasket problem somewhere along the lines of how sleeves drop. Interesting concept none the less.

I'd much rather see a customer put money into a aftermarket crank to combat the oiling/bearing problems these engines face than a block guard. The only engines I've ever seen split sleeves is engines that were detonated. You really have to understand what's going on and wrong during detonation to understand NOTHING can help you if your engine isn't properly tuned.
When a engine is detonated the pressure in the cylinder goes from 3000-4000psi(normal)to north of 10,000psi. The best way to combat broken piston/rods/bearing/liners/head gaskets is to not rattle the engine in the first place. My EJ has been north of 30psi for a while and that engines death will be the #3 rod bearing long before a cylinder. Buying into a crank that oils correctly is really where I see the value. If the engine is tuned properly with respects to timing/boost and octane it doesn't break in the cylinders. When you deal with experienced engine builders that can really perform a accurate autopsy you can see the cause of death. When you're dealing with people that have less experience you get finger pointing at a failed component instead of looking into the cause of the failure.

I think homemade brought up another really valid point in the differences in material and how the expansion/contraction and natural dynamics of the engine occur, and need to occur. I'm not saying this step is wrong or will be unfruitful, I'm just saying I would look hard at other parts of the program before spending this money.

Thanks

Jay Meagher

^ the stock sleeves are so stout as long as the tune is right and fuel is good. How is cooling going to be with the smaller holes s and r??

^^ +1 wondering how this will affect cooling. Most of the block gaurds I've seen Honda guys running were on drag cars.

Not hearing of any heating problems with the Outfront blocks and they, "look", like the flow is restricted just as much as these.

I agree oiling can be an issue with our cranks but no sense in just looking at only that. Maybe someone can put all these different mods together in one bulletproof motor that can laugh at the occasional uh, oh. :O

S&r, need a guinea pig, got a large single scroll borg warner sitting here looking for a strong block. You know how they like high boost.

...as always, YMMV

lol hondas have been doing this for years so much so they even have tons of ebay knock offs for it will it be installed like on the hondas where they leteratlly have you beat them in with a rubber mallet lmao also how will this affect cooling since it is installed in the coolant passages around the cylinder where coolant would normally flow freely between the heads and cylinders

I wouldn't say freely- take a look at a headgasket. However I would like to see one laid over the block. The holes in the deck plates I have experience with line up to to the headgasket really well.

Here is the first STi to my knowledge that features the Subaru Block Supports by S&R performance - it is claiming 65 psi on a gt45R turbo with GT40 wheel!!! It is a DD and has no problems with cooling FYI. Runs like a champ.

its 1000+ cfm @ 65 psi bro with nawwwwws lol.. ported & swirled heads, bored over STi block, bigger valves, etc. I see no problem hitting 1000 hp to the crank. To the wheel- most likely 750-900. This is just my opinion though. Take it for the .02 it is worth lol.

Yeah Ill stand here and hold my breath till it his 900.

Thats the smallest GT45R I've ever seen

Perrin BOV....900whp

Factory Perrin Intercooler Piping

Thats not a 700hp setup much less 900hp I would be suprised if that car cracked 550whp on a dynojet.
