Title: K03s, K04, K04-064 wastegate
Post by: yan20VT on August 05, 2023, 02:35:17 AM
Hello all, hopefully I you can help me with that:
Anyone knows the wastegate flapper diameter and the bore diameter of the following turbos
1. K03s
2. k04-023 TT 225hp turbo
3. K04-064

Additional I read that the k04-023 wastegate opens around 0.48 bar and the K03s around 0.4 bar,
The k04-064 less around 0.3bar,
Is it correct that the k04-064 has the softest spring?
What are the pressures that the wastegate open?
Thanks
