How long have your 918's Lasted Heres the deal I have a TR 224/.561 114 with 918's. I have about 4500 miles on this setup, but I am buying heads and I am keeping the same cam. Should I reuse the old 918's or go to a new double spring setup. Money is an issue here so let me know what you guys think. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> Will may 918's hold up? The car is my daily driver.

Re: How long have your 918's Lasted Thanks for the reply. I will be making a fairly long trip this summer and i'm really just looking for some reassurance. You only here the bad things about the 918's. I am hoping this post turns into an advertisement for 918's!

Re: How long have your 918's Lasted I would get new springs. Doubles preferably. I know some people do but I've always heard it's not a good idea to re-use springs.

Re: How long have your 918's Lasted I would reuse them, but plan on replacing them in 15K miles. I have stock heads with 918's now, but plan to install S2 heads when it hits 20K miles on the springs (at 10K now).
If they had 10-12K (or more) miles on them, I would replace them however.

Re: How long have your 918's Lasted I would just go with a double spring set up. Put it like this. If you ever want to go for a bigger cam in the future, your heads will already be machined for dual springs and you wont have to take em off the car again to get teh pockets cut. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: How long have your 918's Lasted I don't plan on replacing my 918s till they get about 30-40K miles on them. BUT, I'm running a rather unaggressive cam (B1) with stock valves and Ti retainers. I don't race the car much at all, and I don't rev past 6400rpm.
918s are a great spring. A few broke due to a bad batch, but the majority of them are doing great. I've had mine since November or December of '01, which was well before the bad batch went out.

Re: How long have your 918's Lasted I would say reuse them if money is an issue.I've had no problems with mine (60 1/4 mile passes and 40 dyno runs)This was even with the time of the bad batch and for the record I've seen broken dual springs before on LS1's.
