Performance Autowerks valve springs
The Home of WERKSracing products!
Asking $200 shipped in the US total. Maybe make me an offer?
Since nobody wants the ZZP valve springs I suppose I can sell these and use the ZZP ones instead. These were purchased from 07blackg5, who bought them new. Installed, then removed, never run. These don't come with retainers, even new from Pwerks! You use your stock ones. Website claims 8500rpm stable in drag racing and 8000rpm sustained in road racing. Probably the best made valve springs around.
These vs a stock valve spring. I can compress a stock spring to coil bind with my bare hands. How stable is that at 7k+ rpm?

They have been tested to 8500 in midgit cars running solid lifter valve trains as well on straight alcohal
The springs are underated. Anything passed 9000-9200 is where we saw the need to make changes to the spring to make it stiffer. Only reason they have been changed is because no ones revving that far out

happy camper, great springs and knowing the story behind them makes them more worth it.
I rev to 7100 on stock springs. I have the balance shaft deletes and plan on installing them when/if I ever install my ported head/cams/springs

Just to make things clear, don't expect the price on these to drop like my other items tend to do. I want to keep these and sell the zzp springs. I just want to save for a camera so I can have one on Black Friday/cyber Monday. So I'll sell these if it gets me a 6D faster.
I'll raise you 192rpm and go for maximum overrevving
eventually anyway

Zzp springs sold, so it looks like these will be used in my ported head! Watch out Staged my RPMs will be bigger than yours eventually to be honest the zzp ones probably would handle 8000rpm too though
