A while ago we were discussing the surge tank setup on the Team Pac-man k20 crx. Art (ALLMOTORPACMAN) was nice enough to hook me up with a whole cd full of pics and videos, most of which will be shown by nikos soon. Heres a little preview, these pics clarify the routing of the custom radiator surge tank setup.









and here's an explanation from the C&R Radiators site:

C&R Racing said:
SURGE TANKS

Also known as expansion tanks, fill cans and header tanks

Using a surge tank as part of your racecar cooling system is a very good decision. Any proper racecar cooling system will incorporate a surge tank. When used properly, it is the ideal manner of filling your system, trapping air, and moving the radiator cap from vulnerable areas where pressure surges can unseat the cap momentarily.

On the return side of a cooling system, pressure can surge as high as 45-50 psi. This is due to sudden changes in pump speed (RPM related) and characteristics of the heat cycle as well as circulation in the system. When the radiator cap is on the radiator, particularly the return side, it is susceptible to this condition. A surge tank isolates the cap from these areas.

Surge tanks should be mounted as high as possible, at the highest point in the cooling system, to serve as an air trap and means for expansion. Plumb a –10 line to the water pump and a –6 line from the highest point of the radiator to the surge tank. This draws air to the tank where it is trapped. Approximately 1/3 to 1/2 of the tank should be air space to create an air “spring” allowing for temperature expansion. Purging all air from the system is the ultimate goal. To optimize the cooling system and insure that all air is purged, use a swirl pot in the return water line in combination with the surge tank.

Due to the unique nature of swirl pots, C & R recommends that each specific application and system be evaluated to determine optimum performance. Therefore, C & R Racing does not offer a “generic” swirl pot, but will tailor a custom swirl pot to your system.

C & R Racing specializes in customized racing cooling systems, and can insure maximum protection for your engine investment and performance.

holy cow!!!

EG....It’s K?A has 1200cc INJ, 18+ Compression and GAS (methanol
will u be using the k20 block stroked or the k24 stroked/destroked?
k20= higher reving
k24= more torque

if u dont wanna disclose any of this info, i can understand why. (be nice if u would though) :lol:

I'm mean to say Ethanol.....


And I Love tooooo tell you but give me sometime and I'll let you know...I'm in a R&D process right now... :wink:


Thanks

(thinking to myself....i bet he's on the phone to aebs or the like to design him a custom k block.)

well, keep us upto date on it
No, it's not custom K block... :p ..It's still stock block... : :D


I'll let you know more info....
