Which will help how?
I'm running E85 currently. Compared to gas, it's super rich.. And EGTs are 100-150 cooler.
Same issue exists.

 

I water cooled my first setup, no problems whatsoever. Thats messed up, can you actually hear it boiling, if its quiet outisde you should be able to hear the coolant boiling in the lines if thats what you suspect. If you can smell it there's got to be a leak somewhere, maybe put a big *** piece of cardboard under the truck when you shut it off and see if you can track down the leak.

 

is it a problem or just something you want to fix cuz its bugging you? it cant be boiling that much water if your giving it the proper cool down time. so you can either figure out some ingenious setup to remove the water in the lines after turning it off or something to keep it flowing afterwards. or just live with the smell and sound.

 

It's not a problem unless I overfill the overflow.
No leaks, you can smell the coolant boil off though.. Just wondering if anyone has run into this before.
