    Self ported blower pic's and numbers

    After my homeport my boost went up like 1-2 psi and it held there at the top when RPM was rising, not dropping as before. 14 psi as i have 2,8 upper. Also my AFR was leaner so I had to add some fuel = also a eveidence that it flows better. Will put it on a dyno later this year
