hi i wonder if you can help me

i want to know if there are any turbo timers out there that do the normal thing but then when they shut down the engine they then alow another timer of say 2 mins to alow my water booster pump to run?

its not for a scooby i have a saxo which i have turbocharged and it seams to be fine running its only at the dyno stage hasnt been tested on the road yet but when you switch it off even if its only been idling for a few mins you can hear the coolant boiling in the turbo so i am going to fit a booster pump which will run all the time normal then stay running for a few mins after switch off im sure the turbo will cool down to a suitable level pritty quickly with coolant through it and no hot gas?

there is the challange for you all. i know its french but it will be fast

Thanks
Si
