hi mate,
sorry to here this,
i still remember kevs escort from last year twisting his first go!
from whot i remember turbo systems said at the time the original shafts would be fine,
kev now has uprated ones which work for him,
if you had the drag redials on you would have had even more strain on it,
so as you say, rethink needed,
it might be worth asking the guy in norway? with the big power saph which ones he uses,
