Things do just wear out on cars like this. Stiffer springs, more aggressive cam lobes, higher rpms, etc take their toll over time.

You mean our 600whp+ race cars don't last forever!? :(

Sad times...bye bye money, bye bye. ;)

But on a serious note, I would've hoped 40k miles would've been more likely but maybe ~20k is just time. That sucks.

Are the supertechs dual springs? I'm not a head guru at all, but I always thought dual springs increased the pressure quite a bit, to the point I personally don't want to run them on a car I put a lot of miles on as I'd imagine that large increase in pressure would start to affect other things like valve seats and what-not. Would rather just run upgraded basic single springs, or beehive single springs if I needed something more than that.

But again, I'm no expert on that type of stuff so maybe I'm way off.

[Murlo26]

They are duals, I needed them though to handle my lift and not many other people have shown any issues with them. But not a lot of people DD with them and get to 20k miles +.

I think Scheides could've used the Kelford springs as they were designed for his cams but the supertechs have proven themselves for power anyway.

GSC also has some now for the X, not sure on the ratings though, I'd guess good enough for 8500rpms+ and their GSC s2's.

I have supertech duals. Wondering if they were overkill for the setup and caused premature wear? Not sure. Thinking of trying some more basic beehive springs instead this time; the supertechs have always been loud.

[Halon]

Exactly my thought, if you need them because you are reving that high, or running that aggressive of a cam profile, then OK. But if not, and they aren't necessary, a less aggressive spring may be better for longevity. That's where I always kind of thought beehives stood out, better than standard single springs, but gentler than duals.

I'm just a cheap ass and always run cheap Crower style singles and don't run extremely high lift cams, or try to rev to the moon.

GSC beehives I've always thought were awesome and what I'd buy if I was going all out. Again they are single springs so I think of them being gentler than duals. But they also seem to have extremely light titanium retainers (lighter than most of the competition) which also helps significantly. So you basically get dual spring performance out of a single spring setup.

I can't speak on the Evo X ones they make though, only just in general.

[Murlo26]

The X loves to rev high, like a honda basically, so I wanted maximum revs. Especially with the short gearing of the X, more revs helps.

Not sure what Scheides' feelings are but I'd vote to keep the high revs on this car. Just my thoughts, especially with a 2.0L motor.

[Halon]

BTW, I'd be surprised if GSC only rated their springs to 8500rpm. They usually seem to rate their beehive stuff to like 9-10k, even with aggressive cams.

The reason I said 8500, I honestly haven't looked, is they only rate their GSC s2 cams on the X up to 8500. Or rather they recommend a rev range of 3500-8500 on them, so not sure what they really means.

You could be right though, I guess I'd have to check.

Says 9500rpms+ on MAPs website:

Id go with this springs/retainers if I had to all over again. They weren't out when I bought mine.
