If you are looking for an additional 180 HP that blower is just not capable of delivering it. Here is the deal my friend. You have an engine that is capable of supporting 1300 rwhp, however your goal is only 900 rwhp. If you lay down a big chunk of money to just meet your 900 hp goal then you will be laying down more money later when you decide to shoot for 1000 and then later even more when going for 1200, etc., you are probably beginning to get my point.

The nitrous guys have chirped in and yes you can go that route I am sure, but then the only time you actually have that HP at your disposal is when the bottle is full, warm, and open.

My advice would be to take a deep breath and enjoy the 720 rwhp while considering air supply options capable of delivering 1200-1300 rwhp whether you use it now or not. Once in place, your air supply will typically not be the weak link due to breakage. Just my opinion.
