RNR o2 dump dp?

[I-luv-em-all]

what is the deal with the o2 dump on the rnr dp does exhaust run out of their? is it nessesay to dump it like that? is their a hp gain if it dumps?, is the exhaust louder with it dumped?, does it mess up the o2 a/f reading at all? any info any1 can tell me about this dp would be coo.

what a dump tube does is it vents all of the exhaust that passes through the wastegate out into the atmosphere instead of recirculating back into the exhaust system. The biggest advantage of the 02 dump is it greatly reduces any boost creep. The system itself does get pretty loud. Check out this thread for a video clip click here this thread pretty much covers all the details and is worth reading.

Some people are still creeping, even with an external O2 dump.

Indeed, if the WG hole can't flow enough then no matter how big the port is it will creep.
