Valve springs

Post by kinggy »

High all I was wandering if there is a performance upgrade for standard valve springs?
(any others models with harder spring rate that will suit)
I have a spring manufacturer in the states that has a vast supply but they arnt familier with the VFR NC30 motor.
any help would be great as i have searched around to find nothing.

Cheers Guys

Why do you want them? If you intend to up the rev limit other internal components will need to change. Consider the rods/pistons/crank if this is the case along with the extra stress that would be pu on the valves/collets and retainers.... No one wants a bust rocker or dropped valve. Capacity increase and slight drop in max rpm is by far the best way for a bit more usable power tho.

Mike Norman / G-force are the people to speak to.

Curious as to why valve springs though? What are your thoughts / suggests?

G'day guys, I'm doing a fair amount of work to the whole motor,
Forged rods and pistons, balancing, heads ported and flow and just thought the springs would need to be
Beefed upto compensate for slightly higher rpm.
I have tried Mike but I think he's a bit busy
Thanks for your help guys
