I'm not going to run 15lbs of boost thats what it was getting when I bought it. I plan on running 7lbs of boost and I'm putting a blockguard in to help the sleeves out. And ARP rod bolts and main studs. If It works out somewhat i'll throw in son rods and pistons. I have a Hondata S200 so I was gonig to run it to 7200 or 7800.
