I participate in the LOTO shootout and it typically is hotter than Satan's butthole out there. I was wondering if utilizing something like this to not only cool myself off, but to also plumb a pvc pipe of some sort into the engine bay to assist with temps would be beneficial. I have been told to run with my engine hatched cracked open to get more air in for the race, but wondering if this would even do anything to help the engine and if so, how much could it actually help?

I would guess no, its cold, but not nearly enough CFM to do anything.

are the engines actually over heating? water provides 100s of times more cooling than air can.

I've considered the above, making it out of an old cooler I don't use, or buckets work too. for sleeping on my 292.

As for cooling an engine? if the system did anything, the ice would be gone in seconds.

The engine isn't over heating no, it would just be to get some colder dense air into the engine for better performance was my thought. I wasnt sure if there would be any value at all and wanted to open the conversation up on the forum. Back when I use to own a Subaru STI we would put ice on the top mount intercoolers while we were sitting in the pits and then remove it and quickly go run. It was good for all of .1 of a second but it helped some.

I must be missing something....... It's been like 100-105 the past month here in DFW area (since you go by Dallas Baja), so how you gonna say it's hotter than Satan's butthole when the rest of August is supposed to be around upper 80's at LOTO. Do they not let you guy's swim while you wait? Honestly, if you want a quick cool off put a decent white wash rag in the cooler, put cold wet rag on your head hanging out the back like a mullet and put your hat on. Do like the Mexicans do. A fan will help.

Wont do a damn thing. Engine compartments do get hot; one engine manufacturer suggested that 175F is the limit you should try to stay under. Yikes! Generator room designers worry about this. I did the calculation once; 6000 CFM of ambient air was needed to keep the engine compartment down anywhere close to ambient. That's a big scoop and it needs just as big an exit hole.

I moved back up to Kansas, but lived in Dallas for 3 years. I agree its hot as hell there as well, last year I feel like it was 100+ and humid every day. There is a ton of traffic out in the channel while we are idling or waiting so jumping in would make me a little nervous. Im not too worried about myself, but was more so curious if the cool air would help the engine run better.

I figured as much. If something like this worked I would imagine alot more people would do/have something like this. Just wanted to get people smarter than I's take.

Marine engines are water cooled not air cooled.

If your bilge air temps are causing overheating problems like vapor lock, get more air in there. Run your blowers constantly or crack the hatch when off plane.

I do that all the time, and not that it would work here but I leave the hatch cracked until after I am moving just to shove some air in there before the side scoops start working.
