not really sure which is more efficient... i would think tube and fin would be. anyone have any first hand comparison experience? obviously air to water would be most efficient at the strip, but i'm looking for day to day driving efficiency. i would like to buy a core after i get my welder and make my own.

 

bar and plate

 

it's bar and plate.

 

can you please explain why?

 

if i rememeber correctly it is because there is a greater surface area therefore it helps dissipate heat a lot faster/better

 

can't remember but the bar/plate is supposed to be 30% more effiecient

 

thanks guys, i guess i'm going to be looking for a bar and plate core.

 

they are more efficient because there is more surface area to dissipate the heat. Sorry, but being a mechanical engineering major, this is exactly the stuff we study in heat transfer. Its also why computer processors have heatsinks, same situation. Anyway, whichever has more surface area will be better, so if thats bar/plate like people say, go with it. later,

- short-A

 

Word.
Best to worst:
1.Bar and plate
2. Tube and fin
3. Extrude
4. 2.5" section of straight pipe(FMP, front mount pipe)
