How long will my valve springs last me?
I have a trex cam with patriot dual dual springs rated up to .660 lift. Trex cam specs 242/248 - .608/.612 - 110 lsa .
I hardly ever go WOT in my car, I might do a short 3-5 second sprint once or twice a week. I havent raced it in about 7 months. Any idea how long my springs should last at this rate?

That is a tough question... I have a 228/232 .588/.595 cam using PRC dual valve springs and I have 9K miles on my cam...
I guess you get a different answer from everyone. They say street use takes away life of the springs. But that is all I use my car for is the street. My car is not a DD....

Yes they were shimmed and installed correctly, I have heard so many different mileage claims. How will I even know when my springs are worn? Sorry for the questions but this is my first cammed LS1 with a rather large cam and I will be driving it 900 miles back to south florida in a few months so I am just worried if I should get the springs replaced now or just ride it out. Thanks for the help so far.

should be fine for a road trip.
worse case senario is you'd get some valve float in the upper rpm....which isn't a big deal on a road trip as long as you drive conservatively.
and honestly...the only way to really know (shy of seeing valve float on a dyno) would be to pull some springs and test them.
i guess that still doesn't guarantee they won't break....but when can you ever be sure of that?

I would say 30k miles. Sometimes when a car sits there and keeps the springs compressed it can weaken the spring. Also if you beat on the car all the time, well it puts a little strain on them as well.

Oh yeah true, well I stored it at my girl friends house in her garage and they will turn the car on twice a week for a minute or two. Well it looks like the guy above you went 33k miles with hard use. Even though its a smaller cam the lift is pretty close to it.

Oh yeah true I didnt think of that, well I stored it at my girl friends house and they will turn it on twice a week for about a minute or so to avoid that and hopefully to keep the battery charged up for a while.

33k miles an still going, even though your cam is a smaller the lift is still pretty close to it. I guess its sort of like a clutch, never really know when the ******* are gonna go out. Thanks for advice so far everyone.
