Intercooler Pipe Kits and Aftermarket Radiators

[Spoonman]

Whoops, meant to put this in the PB/PC forum - can a mod move please.

For some reason that I can't remember, my attention has been drawn to intercooler pipe kits and aftermarket radiators from places such as Forefront Industries. Does anyone have either one or both of these?

Radiators - is it as simple as a bigger radiator keeps your engine cooler? Logic tells me it's not, otherwise everyone would upsize their radiator, as it's not overly expensive.

Intercooler pipe kits - is rubber hose expansion under boost really an issue? Is replacing the hoses going to give a power increase? Is a pipe kit going to do anything other than make my engine look pretty?

Interested to hear experiences, thoughts, opinions.

No point putting in an aftermarket radiator if you car is not continually overheating. they are designed to run optimally at a certain temperature range. There is no point dropping that range if there is no issue.

Same with pipework. Sure if there is evidence that hoses are collapsing or bulging but if it is only minor bulging you will hardly notice anything. Not sure if the PB/C is actually prone to overly flexible hoses.
