let me get this straight....they basically filled the empty area between the sleeves with something, drilled cooling holes into it, then added a closed deck? :eh:

 

yes. they filled it with parafin wax @ the bottom to create an open airspace. they added the block fill, drilled vertical holes, and heated it to melt the wax back out. this creates open airspace or chambers for cooling to ensure that they don't hinder cooling around the cylinder walls. in theory... added strength, without sacrificing cooling capabilities/exessive weight gain

personally, i had never heard of it until i came across this motor. but, sinceERL did it... i imagine there was a purpose

 

Expect that motor to overheat like a mofo if the water jackets were filled. There's really no way to efficiently drill that area to allow coolant to flow properly as it flows from side to side, not up and down. That's about one of the stupidest ideas ever. :huh:

 

i already contacted ERL asking about that. i'm hoping to hear from them tomorrow.

 

this thread should be sent the shitter...

 

i've heard of race teams doing that for their race motors for added strength. but on a street driven motor that is not the brightest idea.

 

hey, it's cool of you to be a dick about it... i'm juss trying to learn before i shell out the cash. if thats how you feel... don't look in it. i don't need negativity my friend.

and as far as cooling... they've been using a radiator out of a 350z... which keeps it @ 190 @ hard driving and 225 @ idle.

 

Block filling has been around for decades. It's not like the entire water jacket is filled with epoxy, it's maybe an inch to two inches deep. I'd choose filling over a block guard because the epoxy will expand with the cylinder walls instead of having two different metals with different heat and expansion rates that you get with the block guard and cylinders.

 

with the block already being sleeved, would the block fill make a huge difference?

 

On a street driven car, the sleeves should allow for more then enough horsepower safly. Look at this way, anything over 400hp on a daily driver is extremly annoying to drive on the street. Granted you can tone it back on a daily basis, but in order to reach that peak hp, you sacrifice more and more from the drivibilitity. So you need to ask your self, are you building a race car or a street car. If its a street car, understand that 400hp is still gonna feel amazing, and even on the best circumstance There arnt gonna be alot of chances for you open that power up leagally. So yea do you want the most power possible at the sacrifice of drivibility, or do you want a powerfull car that can be daily driven. Just think on that
