NO NONE NOT ONE ..... really....

my buddys 02 ta had 2 pistons kissed because of blue stripe failure (with a tiny b1 cam)....
my 02 with .581 lift is showing signs as well...
if you could run these things up to .650 with no problems then comp woule not recomend them to .600
they would say .650 and the only thing that would change would be the PRICE...duh

why would ANY manufacturer sell something for less then they could get for it???
that just dont make sence...

Joking buddy, gotta have a laugh here and there.
You're right, there have only been 2 or 3 threads about failed Manleys...but there are many times more 918s in the field in use. I personally dont feel that the Manleys have the valve control ability that the Comps do. And no, I'm not up Comps butt, LOL. I have purchased products from all of the major valvetrain manufacturers over the years. Whoever offers the best product at the right price is what I buy. OK, I'm done now

I'm running 918s with a .598 lift (not an XER) grind and no problems. With their recommended lift being .600 I fall within the appropriate range and why put more hp robbing strain on my motor with oversized springs????

I know for a fact that engineers suggest a safe operating range and that does not represent what a spring will really support before failure. I'm comfortable with what I'm running.

The 918's are good springs, but my FMS-9 cam killed them in 10000 miles. 232/236 .585/.595 lsa 114 plus 4. I would say get something a lil stronger if you plan to drive many miles. Allan Futral told me to change the springs as soon as I got the chance and my procrastinating cost me an engine.

Ouch, sorry to hear about your motor. Did the cam have an aggressive ramp rate?

The .600" lift is not the coil bind height. If installed at 1.800", then coil bind doesnt occur until .715" lift. I'd say .115" away from coil bind is more than enough!

Check sig. Many people do the same thing. There great springs just change them as needed. I'm not the least bit worried about my setup. Especially since my best friend owns a speed shop

Yeah, there have been 2 or 3 failures of blue stripes, but what percentage is that of the total number of blue stripe owners out there? Alot less than 1%. No spring is going to be 100% fail safe, because if there was one, it'd put the rest of the manufacturers out of business.

I have over 25,000 miles on my blue stripes and I don't think twice about them causing me any problems. When I eventually take these out, I'll replace them w/ another set.

Exactly just keep them maintained. Also your only hearing about the seldom ones that break, there are tons of 918 users out there. I'm sure others break too. I'm sure that there are other great springs out there but the 918's are great to and proven as well. Just my .02.

The one other thought I'll add to the subject is that aggressive ramp rates will have an impact on spring life and pushing the envelope of the advertised lift. I would have gone with a bigger spring on something like an XER, but feel safe running just under the advertised with an XE grind.
