Seeing if anyone knew around what power you start having cylinder distortion, please specify dynojet/mustang. Thanks in advanced!

 

1,000 hp! dew it josh!

 

We made 921whp with no block issues on stock block no concrete.. the sleeves over time will split though with any good amount of HP..

 

i was wondering this also as im gearing up for an engine build.

not trying to hi-jack the thread, but at what point do you even need to sleeve the block?

 

You dont sleeve these blocks you can fill them with concrete though..

more than u can throw at it 1000+

 

Mike have you all had any blocks split? I don't want to fill the block because this is a street car, but I know if I ever port the head and put some real cams in it, its gonna make 900 easy. Should I start looking into a destroyer or just see how far and long this 2.0 will last lol

Sorry on my phone. Destroker*

 

You can run a filled block on the street, you just cant fill it all the way. Mine is filled right to the bottom of the water pump passages.

 

Really? You have no overheating issues street driving either? What kind of cooling setup are you running. This is what I was thinking of doing if I found out it could be done

 

It might help with the head cooling which is were most of the heat is created. I would use a bigger overflow reservoir to make up for the volume difference, maybe a lower setting thermostat and use the super cool additive. I'd like to hear what the guys that have done it think.

 

dumb question but are the blocks really filled with concrete?? first time i have ever heard of this

 

They make a special block filler but yeah its just like concrete or a stiff grout. V8 guys been doing it forever. It stiffens up the cylinder walls so they don't distort and alot of drag cars that are still using a stock style block may be completely filled but your talking about a short couple seconds of run time then shut down.

 

Yes, when you starting making a decent amount of power it creates a TON of cylinder pressure and if not reinforced, that pressure will go where it's not supposed to and split/distort your cylinders
