OK guys not sure if your gonna be able to help me but here goes.....

MY95 Prelude doing around 120mph and you get a knocking sound (like stones hitting) from the front end of the car. It will be there till you drop below 100mph any ideas???
There must be a couple of prelude owners on here somewhere!!!

Cheers

Go one then ill say what the other 19 people that have looked at this post wanted to say........Dont go over 100 mph there said it ...problem solved

 

Is it related to engine load or does it happen if you dip the clutch at say 120 mph?

 

Nope its just when cruising or accelerating at over 100mph

have a look around the underneath of the engine, does it have a plastic under tray? On an old car of mine one of the bolts holding the undertray on came loose, started flapping at certain speeds, sounded like there was a spanner rattling around in the engine bay.

Check all things that could come loose and may resonate at high wind speed.
