reverse cooling

[lyonsy]

ok in the speedway car iam building it runs a a rear radiator so basicly none of the stock systems transfers over.
so running an xflow which is a det prone engine what whould happen if i reversed flow through the engine but i can quite easily still have standerd flow at the radiator.
will this help reduce heating problems and detation and make it more reliable if the head is cooled first then the block as the head is alloy to.
thanks

I have zero experience on this but common sense tells me that it should work just fine provided you have adequate cooling capacity to begin with. Some of the race guys might chime in to tell me I'm all wet too

This is exactly the way the later model engines are set up. THe alloy head temp should stay closer to the temp of the block and the head should be cooler. I don't see any down side to this.

I would have to check some heat transfer notes, but I think the heat transfer of exchangers perform a tad bit better in the radiator when the flow is going up rather than down. To me that would make sense since you could short circuit the flow easier if you are flowing down vs gravity assisting better distribution when flowing up.
