More Tracks R Going 1/8 How to gear a low HP Car??

I run 433 spooled in a bullet proof 8 3/4 like so many have already replied I simply run the same ratio 1/4 or 1/8. That being said I am not really that serious and our track is 1/4. If we changed to 1/8 I guess I would rethink my position. I stay just north of 10 so as not to end up in a different class. Going below ten is a black hole for money and I ain’t got it. To a serious racer my Philosophy is blasphemy. I just like getting out there and throwing my junk down the track.
