Maybe he was beatin on it before they had warmed up enuff. I'd think it has to do w/. the Ti or steel temp, not outside temps, cause I'm sure it's hot in LA this time of year. Or it could just be 1 of those things that occurs from time to time or a fluke.

Good thought Tom, i hear its a good idea to let the valve springs get some heat in them before you wind up the RPMs'.

Sorry bout your luck skipper, glad it wasnt too major!!

When springs are initially installed it's recommended to go through a heat cycle before flogging them, but that's for the springs, you broke a retainer. Could just be a bad temper or other defect in the metal there.

The patriot springs don't come with titanium retainers. They're a titanium ALLOY. If they were real titanium retainers they would cost a lot more than $255 for a set.

Ahhh, I did not know that (the alloy part or the price, I thought that they were much more expensive)
