m8 cossie is running 2bar of boost and 470bhp NOW the problem being while accellorating between 3500-4100 revs you can hear what seems to be turbo stall/chattered does go if you plant the pedal though!

Is running T4 turbo and a Bailey d/v with cone filter!

 

Sounds a bit like surge............basicly the engine can't consume the air the turbo is supplying..............i'll not try to explain,best of reading Stu's write ups

 

yeah 2nd that, surge.

 

thanks for replies so what's the repair? I'll do a search also

 

sometimes a bit of mapping can get around it,,, but it really needs to change the engine spec

 

Again.. sounds like surge
