OK guys, building a 2.0 Zetec Turbo engine in a Series 2 RST shell - i've got a Pace Alloy radiator from a S2 and i'm not sure it's up to the job for cooling a 300bhp engine with a huge intercooler in front of it...

Was thinking - could i run pure coolant rather than diluted - would that make any change?

Also - could i simulate a pressure load on the coolant system (like we do on F1 cars) to allow the coolant to reach higher temps before boiling...

Opinions?

 

Pure anti freeze will do virtually squat extra except find leaks easier.

All Car engine cooling systems are pressurised to raise the boiling point and assist flow.
