I currently have a Stegmeier Stage 7 ported Eaton pullied for about 17 PSI. The car has been fun with this setup, but I'm ready for more power. The only problem is, I want to keep the same blower noise level that the ported Eaton gives me. The only thing comparable I've heard is a 2.2 KB, but that's not going to give me much of a gain over my current setup. Any thoughts on other options? I'd like to venture somewhere north of 600RWHP. I know I could add a shot of nitrous, but I don't want to mess with that and there's nowhere near me that refills bottles.
