Hello! I'm wondering how stiff valvesprings that will be optimal for my GTV6 2.5 engine. I'm having 282-degree duration cams with 11,4mm lift, thinking of reving max 8500rpm. Can I have different stiffness on exhaust/intake? (the camlift is different, of course) Does anyone have any good formula to ...

Help: Titanium valvespring retainers

Hi!

I have a vague memory of someone selling titanium valvespring retainers, but I can't seem to find the post anywhere! Have I dreamt this?

Please post the link if you know what I'm looking for.

Also, if someone tried it, tell me why and what you think. Also tell me why I should not use them.

:)

you would have to replace all three at once with the aluminium-thingy, otherwise the one not replaced will take all the force instead of 1/3- of the force...

But I like the ideae! If someone come up with .cad drawings on each donut, i would almost pay a quarter or two to get it!

Keep it up!
