Trippen Out

just curious if i had a big res would that help with my temps.. i mean more water so it would take longer to heat up the loop so it would keep the system cooler longer right.. or prolong the amount if time it takes to reach full temp.. at least this is my logic would this be correct or does it not matter

There has been lots of debate on this, I have a 1 gallon res w/heatercore and can run with the fans off for a long time. IMO it helps.

your the guy selling those heatcores right.. let me ask you can you use any heater core or is there a certain reason why those bonni cores work well.. i have acore for my ford bronco that iw as thinking about using .. and i think it would help too has anyone tested there set up with differnt size res.

I have a single 5.25'' bay reservoir and the coolant moves through fairly quickly. I can see how more standing water would bring warmer water closer to room temp than a smaller res. I don't see a significant difference though, as the coolant is going through the radiator anyway.

true but since there was more water it would take longer to heatup right and when you run cooler water through the radiator it wouldnt have to remove so much heat meaning you would get closer to ambient temps again this is just my logic if the water running through the radiator is only in there for a few seconds it can only be cooled down so much if there is a lot of hot water it can only be so affective but if the water going into the rad was less hot becuase of the volume of water would the radiator be more affective keeping the water temps down so when it runs across the block its able to pick up more heat keeping it cooler ???? you might be righta bout that much of a differance but if it means 2-3 degrees would it be worth it

Just a thought... but with 600-1200l/h pumps that are used in WC systems... You would probably have to have a massive... massive RES to get any benifit.

wow thats a ton of flow i dont have one of those there fancy do-dads ive got a stanard pump that came with my bigwater SE .. so might a larger res help out ?

Bonnie cores are favored because of their size, they fit two 120mm fans nicely. You can use any heatercore you can find, they are all basically the same just different sizes and tube configurations although all american car heatercores have a 3/4 and a 5/8 tube on them. Some of them have a full length 3/4 tube and others have one end expanded to 3/4 (mostly aftermarket ones). either one is easily modified one way or another to 1/2 tubing.

I see your logic, but this would enact more of a "delayed" warming up of the loop. The larger reservior would make it take longer for the loop to warm up, but it would get warm eventually (within an hour or two), but for all intensive purposes, it's not all that expensive to have a large reservoir. The matter is just where to put it, and I happen to have all my things inside my case, and that's the way I like it.

a larger res will keep temps down for a limited period of time, the length of that period increasing as the volume of the reservoir increases

but sooner or later, the entire system (including the reservoir) will reach equilibruim, and you'll get the same temps that you would've with either no res, or a smaller res


theres no true benifit to having a larger res, and there's been lots of debate on it, but its proven that a larger reservoir will NOT lower system temps, becuase the water in the res will eventually equalize to the temp of the rest of the system, so the extra volume basically becomes unimportant
