my car makes a groaning noise when changing up the gears, only for about a second though. It also only happens under full throttle a t high revs 5,000 rpm or higher, is a little worrying though. The gearbox is great, no crunching at all or whining, and the clutch has done less than 1000 miles, all gearchanges are very smooth and nice, its annoying because its putting me off booting it, if i change up a gear below 5,000rpm it dosent do it. Sounds like its coming from the engine bay, definitely not the gearbox. car pulls like a train still. Any ideas on what this could be would be most appreciated, thankyou very much.
