There's a shut down delay timer installed on my Esprit. It's non-op right now, and I'm inclined to remove all the wiring and such as it creates a wiring mess.

I understand the logic of a shut down timer so no concerns there. However, I'm wondering if anyone has any experience with these? Or, more specifically, coking in the vicinity of the oil supply causing premature failure. Do early esprits really need a shut down delay timer? I drive my car on the street like a normal person.....

I'd rather leave my car off and in gear when parked...

Personally I've never been comfortable with the thought of the car running after I've left it. Particularly if it could be running in an enclosed space (i.e. my garage where it is parked 9 out of 10 times).

I'd rather sit in the car for a minute or so (outside obviously) and then just shut it off myself. Maybe I'm just old-fashioned that way? :shrug:

Besides, you might as well savor a few last minutes in the car before you have to get out.

Just drive conservative (no high turbo boost) in the last few minutes of the drive and idle it for a short time after you park.

Not sure on esprits, but turbo timers are more so used/needed for turbos that are ball bearing and dont run coolant to allow them sufficient time to cool off. As long as if you do drive it hard or long (low load off idle) just let it sit and idle for about 30 seconds it'll be fine. I think most of these cars get driven so little and serviced so much you'll be fine. Not to mention i know they arent ball bearing, just not sure about coolant lines.

A turbo timer is not necessary if you use a little common sense and drive it easy before you park it. Use good quality oil and change it regularly. The turbo timer is meant to prevent coking the bearings when using older technology oil and putting it away hot. Certainly not necessary if you have water-cooled bearings and synthetic oil. I would remove it. Just another thing to fail.

The Esprits before 89 did not have water cooled turbos. After 89, they all have water cooled turbos. No ball bearings though.

a timer makes more sense for Diesel that has high EGT's

turbo timers are gimmicks and are for people who think it's cool to walk away from the car while its running, even for ball bearing turbo's its pointless

simply staying out of boost a minute or so before you turn the engine off is all thats needed.

I put almost 200K miles on a T3 turbo which was oil cooled only and ran 18 PSI of boost...... and non synthetic oil was always used due to being in the late 80's and early 90's when synthetic oil was new

Do not see why ball bearing turbo's would need it any more then a conventional turbo.
