Those with dual valve springs. How long do you let you car warm up?
#24
I let it idle for about 30 seconds, then I start driving... I don't go ver 2500 rpms until it's fully warmed up. I have PP Gold springs, been using them for almost a year now (5k miles).

They are more brittle when they are cold. Not as much flex means.... snap! the heat gives flexability, the particles that make up the metal are moving around more (have more energy).
With that being said I dont usually let my car sit and idle. I keep the RPM's low until the engine reaches normal operating temperature, and then I blast.

What about in brutally cold weather. My car is my daily driver, and temperatures here have dipped well into the negatives. I assume when the engine is that cold, you shoudl probably warm it up even more before driving. Im just wondering if the springs are too brittle to even start at those temps. Guess Ill find out next winter!

Start it up and go. Maybe wait a minute or so. I can't even keep it under 2000 rpm at first as I normally hit a 50 mph road almost immediately and have a 3500 stall converter (going to 4000 as we speak).

Start and go. I always heat cycle them when new and then thats it.
Who knows. I figure that a spring compressing that fast and hard for 30 seconds is pretty well warmed up. I read alot of the spring failure threads. I don't know - I do not see any that say "I started my car romped on it cold so it broke a dual spring."
It is always "I broke a spring I installed myself while pulling into my driveway after I beat on my car for 2 hours" or "It busted while while driving normal."
Conventional wisdom says to let em warm up. There are lots of things that will bust a spring besides this.

Since I have duals (which I should probably not "rely" on) and am very lazy, I classify that as normal spring wear. Similar to the wear on the (albeit less brittle) stock spring. A spring is consumable like a clutch and I waste on my clutch too. I was by no means advocating not warming them up tho. But also how long does it take for a rapidly moving spring to warm up? I can't imagine it would be too long. When I waste one of my PPduals I'll post up and you guys are can laugh at me hehe.
