I have an '07 WRX and was going to get a turbo timer for it. But then a few people told me that it was a waste of money/time to have one on a '07 WRX. Heres what the guy said.
Kevlar: it's because of how the coolant system is designed/setup
Kevlar: the coolant goes from the turbo to the coolant reservoir, and the reservoir is above the level of the turbo
Me: so a turbo timer is a total waste of time on a '07 WRX
Kevlar: so when you shut the car off, the coolant in the turbo heats up and rises through convection up to the coolant tank, pulling in cooler coolant and repeating the process
Kevlar: yep, waste of time and money
Kevlar: just dont do a WOT run and shut the car off immediately after, lol
Kevlar: but with normal driving, or even some heavy-footed normal driving, there's no need to let the turbo cool before shutting the car off
Is this true or not? Cause if it is then i wont get one but if it is not true then i would like to get a Turbo Timer. Thanks for the help.
