Just after a rough idea on how much boost a standard RB30 with a 25 head can reliably take. Should mention that this car is only ever thrashed.
There are some ppl with big numbers in the dyno thread, but i dont know how long any of them have lasted.
Was hoping for around 1 bar and, yes, tuning is happing at the same time.
thanks in advance
P.S sorry, I did search. You try putting those words in and see how many pages you get
