Increased Engine Power?

I have a Gas Workhorse 8.1 with Allison 6 speed and want to increase power. I have added Banks Power exhaust systems on 2 coaches in past and was very pleased in Mts and on short entry ramps. I now see they have a new water-methanol injection system that adds more HP and Torque than their header systems. Has anyone used this kit yet and if so what are your thoughts? It looks like a much simpler install than the complete header and exhaust system. Also, any other tips on how to add more power? Thanks..

    The 8.1 comes with a big exhaust pipe. You could spend a fortune and not get much more power and probably at the cost of reliability.

    Another live with it vote or buy a DP.

    all that stuff is just hype , very very little difference if any could be measured by a computer . if you want more power get a bigger engine .
