How hot roughly

Hi All


Odd question for you , How hot do you think in Deg C the Intake Runners get with normal running (engine side). cant test myself as making new runners and what i make them from will depend on rough temp


Thanks in advance

as watertemp goes to max 90~100 degr.C, I would think no hotter then that, probably quite a bit lower due to cool air going through during running engine .....

Probably not too high, I would guesstimate around 50-60 deg. C.

up to 130°C... the temperature of boiling coolant.

it's not the temp when running that matters, it's the temp after you switch off the engine!

Its the inlet temp that matters... but still you're right, I always wait for the fans to stop before, switching off my engine.

A plastic inlet will get less hot than an alloy one, but won't withstand high boost turbo and also since you have an intercooler inlet temp. doesn't matter that much. You could try and heat wrap it like they do on the exhaust side and it works.
