It helped me dust anybody trying to get near me. I can take an RX-7 any day. I love it. An assortment of colors to choose from for piping. ONly thing it did performance wise was let my auto rev slightly higher, therefore increasing the power band.
Quality is awesome.
Have had it over 30 psi, and runs 26 psi all day. No signs of oil in the intake, and very little shaft play. Positive boost starts at 3400 rpm.
