[QUOTE="MG0h3, post: 16046397, member: 164690"] Thanks Godstang. I need to reach back to VMP on their max rpm. I suspect its around 21500 based on their pulley/boost charts. Whipple is 18k. From talking to a couple on here and seeing their 2.65 setup make 23-24 on a 3.1/4lb at sea level, I SHOULD be able to do that with a 2.6/4lb up here at 4k'. Is the math on calculating CFM really linear though? My increase in boost vs. blower rpm increase has decreased as RPM goes up. If it's a linear decrease thats fine as that can be calculated, if the whipple is just choked that's another thing. I suppose I could throw the 4lb lower on now and spin the whipple harder as I'm still a touch under max. I just feel like I'd be spinning my wheels due to how little boost I picked up in comparison to the large RPM increase last time. [/QUOTE]
