They have coolant and water mix in the block, heads, and manifold. It just sits in there and absorbs the heat it don't circulate because there's no water pump.
How much do they want for one of those things so I can buy one RIGHT NOW DAMMIT...!!!!!!.... but if it dosent have A/C and cup holders iam not giving you my money.
Like top fuel dragsters, they have none. I think it's because they don't run for long periods of time, so they don't need them that much. And in an engine like that I don't think a radiator will do much.
This is like, beyond dumb shit to do with horespower, to have the thing nudged into place just so it can drive 50 feet in a straight line pulling some giant thing behind it. And the fact that it takes forever for the thing to be set up to do this, and that the actual action takes place in the duration of 5 seconds....wow
