Valve Springs

Here's a reality check for you. At the left is our newest spring for the B series engines. It's stable to 12,000 rpm. It specs out at 70psi on the seat with 222 nose pressure at .550" lift. Price is $400.00 per set. At the right is a Pro Stock spring that's used by all the top running teams. It's made of titanium. it costs $400.00 (per spring) and it's capable of controlling valve motion at 12,000 rpm. It's a throw away item after 8 runs. Pressure......you could put one of these atop your car's shock absorbers and chunk the springs. If import racing survives, you'll be seeing this sort of thing in the future, as racing becomes more lucrative and competitive.
