Ok so let me ask this. At what point are studs and springs necessary
sent while trying not to JJ My rods!!!!!!
I know Matt at Full Force recommended studs and springs for me with the S468. I was only running Stage II injectors, but was hitting 45 psi of boost wide open.
He popped a head gasket on the first drag pass with that turbo. I think it's all about volume of air and psi. I'd say anything over 40 psi is danger on stock studs and springs.
