Change Springs or Not to Change Springs
I currently have a turbo'd 408 with a small 220 224 581 581 114 lsa cam. I have comp 918s in the car right now. We are going to start running more boost on the high setting between 15-18 psi. I have heard that the higher boost can actually hold open the valves will that be an issue with the 918's or should I go with a dual spring?
If I need to go with the dual spring whats the favorite these days?
Thanks,
Kane

I would use the patriot golds, they are a dual valve spring and have titan retainers. They are the best for the money IMO. You are going to pay at least twice as much with the 921's.

The harmonic control of those has been well studied by Comp.

Vinci has them >>>>>>>
I think they call them "Extreme", but they are on their web site. You can shoot Joe Vinci an e-mail to confirm. They are less than the Comps in price too if I remember correctly.

This is a no brainer duals all the way for that much boost on the aftermarket cam. Comp 921s if you can afford them otherwise Patriots newest gold versions, etc., etc., and your good to go!

I am just trying to figure out if I can get away with just buying the springs instead of the whole kit. Since I have 918s on there now will all the other hardware work with the new dual crane springs?

Thanks 98REd.
So the next question is I can get Patriot Golds kit for $279.50 and the Crane 144833 kit for $439.99. Is the it worth paying the $160.00 more for the Crane's?
