Knocking/Rubbing under hard throttle in 1st/2nd

[nick172sport]

Hey,

When I accelerate hard in 1st and 2nd, I get a strange rubbing/knocking kinda noise. It sounds just like traction control kicking in, but its not that as the light doesn't flash and I have plenty of grip.

Anything I should check?

The sound is comming from under the gear-box kinda of area.

Help asap would be awesome as its doin my head in!

Thanks
Nick

Is it just under harsh acceleration?

engine mount under battery, tighten it up.
