dual springs needed?
dual springs needed? IS it necessary (or highly recommended) to run dual springs on a supercharged engine
I have a smaller cam (571 lift) with the PSI Beehive springs now, and with a new bottom end, will try to push boost into the 15 psi range.
What do you think?

For the price, I went with Tooley duals. I had a PAC 1218 snap and valve only mildly kiss the piston without dropping. But the single spring also had 3 years of duty on a .598" lift cam which was probably the most influential factor. Added boost and it broke.

How many miles you planning on putting on this thing? How high do you rev the motor?
I run with roughly the same lift and 21lbs On pac 1218's. Don't rev the motor much over 6k though.

Not a matter of cheaping out. It's a matter of choosing the correct spring for your application. If a dual spring isn't needed there is not reason to run one. Running excessive spring pressure is just a bad as to little pressure. I think it falls along the lines of "bigger isn't always better".
Never ends....
