the longer a bolt gets, the easier it is to overtighten and break. Pretty simple, but it's an easy fix seems like. If someone lets Vortech know, I'm sure they will address the situation.

I thought you stripped that bolt, not broke it.
The bolt doesn't strip. The vibration of the impeller is communicated directly into the bolt and it just chews up the threads. Harmonic/unpredictable vibrations probably play a significant role in when or if the failure will occur. It took mine a few months to show up.

If it had been due to simply a stripped bolt, the failure would have shown up almost immediately. I think that is a *key* point and rules out faulty installation as the primary reason this happens. Most people see this event months down the road - not immediately.

The take-home message: It could happen to you, or it might not - regardless of how well the kit was installed. Plan accordingly.

oh I thought it was stripped. that's why I thought it was installation error.

FYI guys...Vortech replaced the bolts in question with class 12.9 bolts. Min. Tensile Strength Rating 12.9 = 1220 MPa = 176.9ksi = 176,950 psi

You can thank jin6 for bringing this up to Vortech a few months ago before he dropped off his 07 S2K. As some people have said the old bolts didn't always break, but Vortech decided to make the running change anyways.

Good to know they acknowledged the problem, *but* - I must tell you that one of the 3 replacement bolts they sent me (in Mar 2008) broke again within a month. Clearly I must have some nasty harmonic issues but please - no one waste my time accusing me of torquing them improperly. It was done correctly.

My attitude is this:

For only $7.65 apiece, why not just go with the titanium bolts which will *never* break. I think that's the entire point of this thread: why roll the dice on these essential (but cheap) items after having spent so much to go FI?

One last thing:

The Vortech manual mentions the proper tightening sequence in order to prevent leaks from the VTEC solenoid. It makes *no* mention of the possibility of broken or stripped bolts, etc. It would be easy, therefore, to assume that - as long as the VTEC solenoid is not leaking - everything is fine. Not necessarily true.

Sounds like you're bitter about your Vortech purchase. Maybe you should sell it and go inline pro (or whichever turbo your looking at). If you're this disappointed with your SC choice, you will never be truly happy.

Vortech purged their inventory of the old bolts in April 2008. Since then all kits have been shipping with the class 12.9 bolts. Most titanium bolts fall somewhere around class 10.9.

The reason it doesn't mention anything about broken or stripped bolts is becuase during R&D Vortech never stripped or broke any. Jin6 compiled a list of threads from this forum and emailed them to Vortech. Before then Vortech didn't know it was an issue.

so the vortech kits now ship with stronger bolts, so I won't have to worry about this if I buy one?
