Hello Dan,
Took the ‘13 ZR1 (stock) for a short drive yesterday. Car is always stored with battery
tender on. Outside air temperature was about 85 degrees.
Started car - last usage was 1.5 weeks ago - and the immediate cold engine idle was
approx 900 rpm. Immediately removed the car from the garage and the engine idle
speed smoothly reduced and settled at 650 rpm (within approx 2 minutes of start up).
The warm engine idle settled at 600 rpm throughout the duration of the drive (at
posted speeds for city and highway roads) with multiple stop-and-go points.
RPM was measured by the stock tachometer.
Hope this helps.
Vern

Hello Dan,
I’ll check the idle speed next time I have the car out and let you know.

Vern what rpm does the ZR1 idle at?Dan

Vern,

It's Jim again, Tell me, what do you think of the GS, 2017 I think it's called Collector Edition, with Tension Blue,Watkins Glen Gray.???? On the form, in C7 I asked what people thought, I think it's a love / hate. No middle of the road. I do like it, I found a Convertible 3LT, don't like the price. Being 70 and just retired last month, must look at everything. Sorry it's so long, enjoy your week, and weekend coming up .

Vern, looked at your pictures, I really like how you put your wife first in the pictures. They are sent from GOD, only the best. I have a very GOOD WIFE also. Best on your sale. Jim

lots of controversy on this Z06 forum.dosent look like they will be able to catch your ZR1. Dan
