Yes your front wheels are spinning up, basically the centre diff is getting a work out! I had a crt.5 that I put mamba 2650 in on 4s, The centre diff (5k oil) got so hot it melted the rubber boots on the propshafts. I had to run thin oil to stop the wheelies but in the end dropped to 3s. Anyway, as your centre diff works it generates heat, so long as its not melting anything it wont matter., but if you can go a bit thicker without upsetting handling then thats less power lost in heat and more on the track.
It has nothing to do with gearing, why would it.
