45 PSI, that is alot of backed up exhaust. I see why you are going to the bigger housing. I'd love to see your dyno sheet.

What rpm range is the pull and I noticed from the video, the rpm's rise very fast. How many RPM per second is the dyno set for?

Are you going to be able to hold it down at the track? It will be fun. Tom
