Well I spoke with Maggie sales lastnight and the guy all but talked me out of upgrading. In a nut shell he said no really big HP gains were to be had by going to a 1900 but from the better IAT. He said for the money he would not do it if my 112 was doing fine. He said MAYBE 20HP but that could be had lots cheaper.

He asked me what boost I would want to run and I said 7psi and he said 7psi is 7 psi on any blower and I would just have a more efficient, quieter blower with better IAT's.

I was like WoW! I expected a snake oil sales pitch with mega HP gains. They advertised 120HP on my 112 when I got it but it was more like 80 as shipped and 100 after my complaints they replaced the pulley from 3.7 to 3.5.
