VP is leaded. It will do some damage to your cat and possibly O2 sensor. The only real benefits are under nitrous oxide or turbo use, you reduce the chances of detonation and can run more boost than you could with pump gas.
An unleaded alternative to VP fuels is PRO race fuels, it's unleaded and works just as well.
I think the vp 104 and 108 are unleaded. I know the rest are leaded. I run the 110 leaded at the track when I am running nitrous. It is 6.50 a gallon up here in NH. That was until the track switched to Sunoco race fuels which are MUCH better. I know run the blue 117 leaded gas--great stuff.
