I'm debating on just keeping my ported v+ blower or going to a larger supercharger. I'm not sure if the gain is worth it or not. My car runs pretty good with just 12.5 psi of boost on the ported blower. I've thought about getting more boost out of it. I want to stick with my stock tb but I see that getting much over 575 whp isn't easy with one but it's also power under the curve that matters. I had a huge headache with a dragon tb idling issue and I don't want to go through that again.
