Cement in engine block

[Trishen94]

So I read an article and watched a video on this. alot of people overseas and a few local have been doing this they are putting some kind of special cement like mixture into the engine block of turbo charged cars. Apparently you can boost the car much more than it would normally hold up ...just curious to learn about it .dont plan on doing it lol... how is this done and why would one do this ? How would the water and oil flow if there's cement in the channels ? And wouldn't this cause the engine to heat up ?

they don't fill the whole thing they only do some of the channels - Steven from JMS did this in Ashay's uno turbo many moons back- that thing was flipping strong

How the **** do you 15000 posts???!!!! you whore

Throw the engine into the foundation for a building, it will strengthen it



It being the foundation until the block rusts away

Actually not

There is special block “cement”

The GTR boys with the RB26 did it plenty, filled half of the bottom of the block with it to support the sleeves

You don’t fill the whole thing

It acts like a sleeve brace basically

Strengthened the block and prevented the twisting that lead to the straight 6 cracking the casting between cylinder at high rpm and torque

Required improved water cooling setups etc which they already did anyway and flow to allow for adequate cooling but they no issues with it

They have been doing this for YEARS in the drag racing scene!!
As far as I remember it was very common on engines running on methanol, because most of those drag motors don't have any engine coolant anyway, they don't have a radiator. The fuel itself cools the intake charge when it vaporises and as a result doesn't generate heat as quickly as normal gasoline would.

Nothing new

Yup!

Yup!

These days they just use more modern materials, often using a type of epoxy, from what I've read

Yeah it is epoxy based iirc

Here's a forum where the guys discuss the different types and the reasoning behind it

I have not heard of people doing this for a road used car. Only ever heard of it being done in the drag racing where you then eliminate cooling completely. The short time it takes to do a burnout and a run on methanol / ethanol or nitro motors does not need the motor to be water cooled.
I would not suggest that for your daily or track racing car.

Hi Stefan makes total sense what u saying but I'm a little bit lort confused lol... doesn't an engine have to be at operating temperature before u high rev it ...ive always known since a teen to always warm up the engine before driving ...do these guys race the engines when it's cold ? Or does it simply not get hot by doing this ...and also how long does the cement last ? Do u have to keep on replacing/refilling the cement or is it a once of thing?

But why use cement ? Is it not possible to use metal instead ? After all steel is stronger than cement my minds working overtime lol

[Ashveer03]

Warming an engine before revving or driving hard is generally just for longevity of the engine/prevent the engine from dying early. Since most wear happens when cold or on the warm up period of an engine.

On race engines, they don't care about wear - they are built to be abused with different clearances and stuff compared to the normal production line daily/sport car engine.

And those engines get rebuilt quite often, those stupid fast cars get an engine rebuild after every season or something like that.

It’s a liquid epoxy based cement with the correct thermal properties etc

It’s just a void filler that removes the ability for the casting to flex etc

Else you’d have to pour molten steel into a cast block

Won’t end well lol

Makes total sense to me now after getting all this Info from u guys ...still watching a few videos and man it's amazing woulda never expected this method ...totally agree with polony pouring hot metal might do more harm than good on the cast iron block ...glad I asked lol otherwise it woulda been another sleepless night on Google
