We run water in the block but it doesnt circulate.
It's there to stabilize, not cool the motor.
Run with the block dry. Bet he wont hot lap too many more times. Lol

It was custom built by Spike http://spikeradiators.com/ , he has a shop next to Roo Man. Roo Man and myself highly recommend him. You can confirm this with Roo Man in his "room" under the categor Technical in ths forum.

It is double thickness and measures 20 X 12 X 3 1/2

Well what I did is run Alka and put a small elect water  pump on it with a trans cooler and fan combo dont take up much room, all because nhra made us do round so close without any cool down time. for years I ran a dry Block less problems of water getting on the track or get shutdown on the line.
But by running alka it takes a lot fuel, Just the burnout and run I use about 4 to 5 Gals, and nitro Is even more about 6 to 7 Gals, were as gas about 2 gals plus or minus. I hope this helps.



But I do not Run Water on The Blown motor at all.

It really depends on wether or not the engine is capable of being cooled. If your build is really hot like fuel or a high output supercharged setup cooling isn't going to be easy.  My setup was designed into the build. I went to Universal Inc of Humbolt Iowa, told them it had to be 25 inches wide and not too high as it is going into a front engine dragster with a 360 Mopar that, depending on the class could run as high as 500hp. The unit they suggested they said could handle up to a high output 429 in a full bodied Mustang and should take care of my setup . The outfit works fabulous! It has a 185 thermostat and you can run it all day long and it runs 185. The electric fan that came with it comes on when it needs to and shuts off when it isn't needed. I hope this is a help. see you at the Nostagia Nationals at Denton TX, Mildsteel.
