An issue with the shop we used to deck the block with a ultra fine finish.
Welcome to Facebook

thoughts?

At ZZP we couldn't get past 700 engine HP on the block. So we changed the block design using some technology from one of our guys experienced in high HP Honda racing. GMR tried a similar approach but they messed on in part of the process causing the cylinders to distort. ZZP has engineered around this and we should be shipping 1000 HP capable blocks this spring.



A block we tested to failure. Sleeve let go, cut in half we found an internal crack as well. Also shown is a new ZZP block ready to go where no Ecotec's on this forum have gone before

 

AWESOME stuff!

 

nice

 

Sweet! Too bad that the block got chewed up like that guys. Keep up the good work!

 

it's beautiful :drool:

 

Tested to failure eh? Would like to hear more about that.

 

Looks as if you filled in the cooling jacket surface of the block around the sleeves with something? AmIRite?

Is this a drag only block, or something streetable?

 

Wow thats nice

 

I want a 1000hp cobalt...

 

Am curious how much something like this would go for even tho i 'd would have zero interest in buying myself

 

only issue id see is drivability and over heating......

 

liquid steel? ^_^

 

this solves ALOT of issues if people got a hold of these.... I mean high boost!! more air, more fuel..... it's beautiful without breaking ****.. all the possibilities..

 

Zoomer - you beat me to the punch!! I had plans for alum LNF investment cast for next month.. both block and head.. made here in philly.. low production run..

 

this is awesome!

 

I feel like GM would have thought of that... maybe there is a reason they DIDN'T do it.

 

is this an entirely new closed deck casting for an ecotec? sand or foam cast?

or is it how the honda guys do and you filled the deck? pretty common in the high hp honda stuff

just stop, please

 

What? I think thermal expansion is a big factor here. It doesn't look like lost foam casting with the seam by the oil filter.

 

i want!!!!

 

Damn that is sexy

 

Your right, most ECOTEC blocks there is a major problem with thermal expansion it's a known fact, from both a performance and reliability factor.
I had my fan turn on at 180-190*, because I found some parts of the block where at 217-228 at stand still, At full boost 240-270- during a dyno run. (thermal gun)

Foam cast is porous, its known to crack in high boost and extreme heat applications plus it's way cheaper to fab the foam cast when compared to a sand/glass cast product.

As for a sand/glass cast product, it is not as porous and it will last much longer. Plus it's known, not to crack as easily than a foam cast product but it cost much higher.

I was going to make a aluminum billet LNF block from Nelson Race Engines, they told me the R&D cost is around $9-14k that was everything from engineering to production. I was going only make 10 blocks to sell. My over head was $3k each minimum.

As for lost foam cast, I got 19 bids from all over the world, the cheapest was from china & brazil each foam cast block was around $1700 - $2600 each. Here in the US, it was $1900 - $2900 each.

Also for sand/glass cast, each one was around $2700 - $3600.

 

this will be intresting

 

in for more

 

lurking in a creepy way

 

and what would be the price for a 1000hp capable block?
