i wouldnt say it was being thrashed, took off in first and it seemed to spike and overboost and then one i changed gears the knocking noise was there.You say it happened after overboost ? Im no mechanic but could you have taken it a bit far and the big end has started knocking ? Im only saying this as mine went last year, whilst being thrashed on a dyno but it didnt sound as bad as that
Im not sure mate, i dont think there are any visible signs. I would take it to a garage to get it checked, or better still get a mechanic come to you, as i wouldnt like drive it with that knocking, you could cause more issues and more expense. There are some very knowledgable guys on here, perhaps give them a bit of time, to see if they see this thread .Wish i could be more help dude .....i wouldnt say it was being thrashed, took off in first and it seemed to spike and overboost and then one i changed gears the knocking noise was there.
is there any signs that i could look for from your experience?
