okies...
tests from today on stage 1 map from rtech on an s3 of danes.
car has no mods at all.. aside from rods i fitted for its upgrade path planned by the owner Dane
before any change, run on dyno on its std airbox and silicon tip, with k&n filter element. airbox had been drilled with big holes in its base by previous owner.
logs:
then 3 inch tip ws fitted along with the FR08001 filter
dyno'd again... no other change
bolt on g/s gains of from an intil best 196.14g/s to 215.28g/s = gained 19.14g/s of airflow
and the before & after dyno is.....

Pretty conclusive to me... and I was surprised to be honest in the difference.. on stock k04, on a stage 1 map, with no other performance mods on it, just changing the tip's and filter. wow!
Also, after this we did some playing with the mapping to see if there's any more left in it, for its lack of mods.. so did a custom map for it.. and eaked a little more bhp out of the girl.
comparison below of silicon tip, rtech stage 1, 3inch tip rtech stage 1, and a Badger5 map on it
This has ended up the most powerful std k04 car i have run so far on my dyno..
started with 251bhp from its map, then rose to 270bhp on that same map but with 3inch tip, then to 278bhp with some tweaks
There was no side effect to installing the 3inch tip on th stage 1 std k04 turbo at all... just more airflow and top end sustained torque = more power.
Well please with this result. surpasses my expectations
