I am ready to put down $4600 for a kenne bell 1700 for my 99 cobra pushing 6.5 psi with the 90 mm MAF and cold air kit it comes with. They claim I will put down 426 rwhp. How much boost are you running on the stock block? Any info for me would be highly beneficial. How loud is the 1700? I can't find any sound clips anywhere and the kb website says it is whisper quiet but I am convinced I'm gonna hear that typical screw type whine. Thanks guys
