Engine temp should be plenty cool so I assume you are wanting to get some cool air to the engines?
|
Why not just remove the engine hatch all together? It will save weight and allow more fresh air around/into the engine. I don’t think any other form of boat racing besides offshore encloses the engine.

My guess would be you need about 15,000 btus or more to make a difference in bilge with 2 big blocks in it.
Don`t know how many btus a bucket of ice is rated at but it`s not even close to what is needed. That ice would do nothing and be melted in no time. You`d be better off putting on a small cooler and running fuel thru it. Cold fuel does way more than icing the intake . That`s my plan anyway. |

I would guess no, its cold, but not nearly enough CFM to do anything.
Many mild bbc’s consume 700+cfm of air. That’s nothing a bucket fan can feed. Would be better to source outside air just don’t restrict it doing so. |
I remember reading many years ago abt Lingenfelter using nitrous to chill an inter-cooler.on one of his Salt Flat runs. He didn't burn the nitrous, just used it to chill the intake charge. Pretty sure the eng used forced induction. Don't remember how much he gained.. Kind of an oddball/expensive option but for a short run in hot weather it works.

How about an automotive A/C compressor on one of the motors and stick the condenser between the intake plenum.
Isn't that how Dodge does it on the Hellcats? |

what make/ model of boat & what engine(s). ?
I am not having any over heating issues, was just curious if a little cooler air in the engine bay would do anything. Obviously much smarter people here have answered the question. This is a good discussion though. |
