I'm planning on a h/c swap as soon as I figure out what cam I want. I'm favoriting the torquer v.2 (232/234 .595/.598 112 lsa) I would like to run beehive springs but, how will they hold up to this cam? will it work on this cam? should I go w/ doulbe srping for insurance? anybody out there running something similar to this? any info would be appreciated.

thanks

With that much lift on the cam, I wouldn't risk running a single spring. I'd go with a good set of duals for peace of mind.

Ditto most single springs are "good up to .600 lift" but thats too close for my comfort. Go with duals.

Sure you can use 918's, just shim them at least .050
I've shimmed mine .060 for .610 lifts, nooo problem, quite the contrary.

The 918's have had a pretty good track record. But as you shim and flex them more, you also increase the oscillating stress in the spring material. The life of the spring is finite, so I would plan a preventative maintenance program and change them accordingly. A lot of guys are running these springs, so you can get an idea on how long they last and then maybe subtract some amount, for instance plan on changing routinely every 10 or 15K miles or something. You need to decide what the number is. The springs themselves are not that expensive, it is the titanium retainers that are going through the roof so any mainenance with an investment in a good spring tool like Vinci sells would make this a snap. I think there is an advantage to using them over a dual from a valve train mass standpoint, but the consequences of a failure are higher so plan accordingly thats all. All of the high performance springs have a finite life, and knowing ahead of time and proper planning is better than hoping the inner spring of a dual catches you valve when a failure occurs.

bigger lift from 918's here. no problems at all.

how many times have you changed them with this cam? how many miles do you take it too before changing the springs?

Never changed the springs. Have about 6k on this cam and about 12k on 222/226 cam.
