First of all im running a T72 Qtrim on a street ported S4. I guess i was expecting better responce but come to find out from you guys, this turbo wakes up around 5k. Anyway to the topic, i was dicussing some things with my turbo builder about my turbo. Ill tell you he didnt build it, i bought it this way. Theres an equation that gives you a comp to turbine wheel ratio. My builder said it was for boost responce and more importantly the evil back pressure. What have you guys heard about this sort of thing and your opinions/experience.

Kind Regards

Did i post this in the wrong section or what. Were talking about backpressure=heat=detonation. Anyone shed some light on the wheel ratios so we can discuss this.
