Supertech vs Sealed Power VS855 Valve Springs
#26
Loose less power in the valvtrain, I'm not boosted and run under regulations, so it's better to do it right.
The soft ST duals could most probably been enough in my case, but as mentioned, don't copy part of a design.
When you have (good enough in your judgement) control of your valve movement, extra springs is just waste.

So many 8200rpm + moments. Less than 20psi levels though.

They would bolt up, but I'm not sure if things would get damaged with the inner spring not held in place fully. It might rub or chatter against the outer spring.

I put some in about 4 weeks ago.
its a tired B6
port matched & polished general clean up of ports
Genie headers
272/264 220/215@0.05" cams 10/9 lift
CR10.5:1
MS2
max RPM 7500
running HLA's
spring pressure recommended by manufacturer 66lbs
initial reaction after running cams in again....smoother at low RPM. More vibrations at the top. But it seems to have smoothed out a little over a few weeks and a few high rpm runs.
will not get a chance to dyno it as the engine now needs replacing. But unlikely because of the springs.
that's as much as i can tell you.
