Dry block

What are the pros and cons of running no water in the block 504" sbjd, no intercooler with 3.9" Holset on. I understand there are tractors out there running dry block with an intercooler but can I run dry block with no intercooler safely ? Eventually we would plan to have an intercooler. |

Go for it, best thing I've ever done! |

Coat the Pistons open up the clearance. Really believe in this. |

Wet block is for hauling manure.. Build it right and wonder why you were ever wet. |

I disagree

Why would you go dry block unless you had to? Run it wet until you have a problem and then dry it up. |

Just curious...when dry blocked how does one change sleeves? And how do you ensure sleeves are tight to the compound for good heat dispersion? Thinking about going dry next time we overhaul. Thanks guys! Hope everyone has and had a Merry Christmas! |

Why would changing sleeves be any different? |

I don't know that's why I'm asking. I don't know never been around the product but from what I am guessing you mix it pour it and it forms around the sleeve that is in the block you run it your sleeves get worn out or damaged. When you drive the old ones out how do you know the new ones are going to fit perfect like the old ones did? And won't the hard block adhere to the sleeves? |

If I understand correctly you don't put anything in the block, just pound them in and go. I don't believe the water gives it any structural strength, just drain the water and go. You will need the clearances changed though. |

Sorry I mistyped. I'm curious of changing sleeves when hard blocked. My bad for not double checking myself. |

Pro's 1. Saves unnecessary expense 2. Has no effect on performance of pass or reliability of engine parts. 3. Decluttters engine compartment. 4. Weight savings 5. Reduced maintenance. 6. Reduces electrical system draw and requirements Con's 1. Cool down time is extended If you aren't trying to run 3 classes per night with a pull off, I see no benefit to a wet block setup. |

running dry ur head might last half as long as running wet |

Might last twice as long too. Seen it both ways. Heads crack regardless particularly if one doesn't use their "head" |

All wet

I've had some issues as of late and I'm seriously considering doing this but how much more clearance is needed? I know some guys around here just run them dry without hard block any thoughts on that? |

We run .018" skirt clearance on a 4 inch bore diesel twin-turbo, no hard block, about 1200 HP. Use a fan to blow air thru the block after a run. NO PROBLEMS. |

What about ring gap? |
Re: Dry block

we run a dry block with intercooler, popped out freeze plugs .o15 clearance on pistons, put leaf blower on a water inlet to cool motor down for second run. no problems, will not go back to water |

Just my 2 cents,
We run a 504 Case 970 as a dry block, with no intercooler. We have all the parts to put water back to it, however I have a feeling they will stay on the shelf and continue to collect dust. A big thing for us as far as draw backs is the cool down time. To be the 1st hook in class and then have a sled change requiring us to rehook would be rough on us as we need cool down time. (We have a leaf blower attached to a foam ice box to cool it down faster through the water ports after a run but that still takes time.) We keep an eye on our EGT and havent had any issues yet. I might add we are water injected also. (So I guess what we call dry block might be different then you) Good luck whatever you decide! |
