The alloy cossie block has been about for some time now couple yrs,has anyone coughed up the 3.5-4k to buy one and has anyone tested one to breaking point as i aint heard anything or have i been missing something?

think 34 chassi or chassi 34 on here is making them ? alot cheaper too pm him

i seen thread its not so much t buy 1 but has anybody tested 1 to see what they can handle

mark , or mk motorsports blocks havent been tested yet , built to the same specs as us alloy drag blocks ,

when i spoke to him the other week it was off being heat treated then going bk to his for final machining ,



id expect an update on them shortly he was on about sending it to a respected tuner for testing ,

The MK motorsport ones will be alot stronger i would imagine as they are going to be machined from a block and not cast! also going to have four bolt main caps and a girdle for added strength

and iirc , diffrent pathways for the water jackets , thicker cores


just a whole lot more beef'd up


deffo will smash the back out of the engine block market imo

Be nice to follow the development of it ay mate' as stuff like this is fascinating

its good that money is still being invested; breaths new life into Cossies; hopefully it will push boundaries too in terms of power

Will look awesome on the spec sheets !

could the alloy block do away with headgasket issues once and for all on high power engines

JonnyBravo

Why would it ?

It will still use the same head so you are restricted in the headbolts that can be used.

I see the main advantage as being the fact he can supply it with any deck height, Martin Hadlands engine proves thats a worthwhile way to go although I would imagine his conversion is still cheaper than the new block though.

Either way some fantastic stuff going on.

just with them both being alloy johnny and moving at the same rate

JonnyBravo

Surely if the properties of the Alloy differ to the heads then it will still move differently ( if thats the issue )

I have no idea, its a fair point though and maybe something it will cure.

At the end of the day the Yank V8's take some mental power, that said so do other engine, 3000hp from a 350z engine for example but I don't know what that block is made of

-beefy-

iTrader: (6)

make me wonder how these super high power us v8's and even 4 - 6 cylinders dont seem to suffer the same issues that plagues big power cossies with gasket issue ?? what they using diffrent to us ???





i did mention to mark about the idea of raising the liner and machining the head to create sort of a cap over the cylinder , thus sealing the bore , sealing water and oilways could be done with a stock gasket ,

it was something he had thought about ,


i wouldnt be surprised if he doesnt have a head on the way shortly

he needs to be producing a cyl head not a block

james kiely

both would be nice mark

If its a new block and a new head, why not just fit a decent engine anyway, as there wont be anything YB left anyway

JonnyBravo

My thoughts exactly

Lets face it MAD, SCS, FMS to name a few have proven some massive numbers from YB's with now the chance of some reliability ( lets face it any 800hp 4 pot engine has a short life ) The issue isn't the engine, its the rest of the stuff you need to have to make it handle that power.

FFD and Xtrac boxes will be on the next wishlist if everyone is wanting a alloy blocked YB with 1000hp in their road car.

Cool bit of engineering but the only people you want to be selling it too is people who buy Millington engines as if their cheaper then obviously thats going to interest some of the more wealthy racers.

Excellent developement and much more affordable too.Would be nice to see this development cureing the head gasket issues with massive power yb's.Also must be a lot lighter?

Rod-Tarry

If your pushing towards 900bhp its all about head gasket integrity. If they want to push Power limits this will have to be addressed. I wish them well testing this block, writeing off a few engines aint cheap .
Beefy- The EVO's can easily push past a 1000bhp with no special gasket measures because although all heads must lift their integrity is not comprimised on that more modern engine , I wish i could say whats been done to mine to try & replicate that on a YB. If they were starting with an EVO engine I think it would be a better starting point. It can never be a YB so why take a 40 year old design as a starting point.

hi mark ,cosworth are doing new heads arnt they

Yes, not sure on prices though

£2500 i think.

But if Mark made then CNC'd out of a solid block you could not have them pre ported to the sizes you wanted?
