Wow good info i was looking into an f1 build in the near future that included a wastegate.Im going to try and find that write up. :beer:There was a write up in MM&FF one time. And I think someone did one on here as well. They talked about the stress and I think it caused a little more heat in the air charge as well. The biggest thing I remember taking away from it is that it wasn't worth it to me.
