[QUOTE="madman1234509, post: 1140203, member: 3910"] I have 40s on both up pipes and a 50 on my intermediate pipe. Only reason the 50 is on there is because I had it from another project and never used it, or else I would have used another 40. Currently the 50 is being held shut completely with boost. No reason to gate around that big charger unless you're spraying the balls off of the truck. I've checked back pressure in the intermediate pipe and its never been more than 1:1 of what the big turbo makes, and we've pushed it to about 55lbs once or twice testing different gate set ups [/QUOTE]
