Fastest 1/4 ET ever in a car?

If those rocket powered cars burn hydrogen peroxide then I watched a pair of them at PIR in the mid 1970’s. It wasn’t long after that they were banned. Maybe it was benzene they burned? Something like that. I was probably 10 or so.
Im not positive, but i think it is hydrogen peroxide mixed with another chemical, (that i cant come up with at the moment).
Basically, the same fuel as the ME163 (not the ME262, that was a twin jet), the nazi rocket plane. Very dangerous, lots of failures, scary ****.
Edit: the 163 used methanol and hydrazine hydrate mix, oxidized by mixing with hydrogen peroxide dirivative, c-stoff and t-stoff. Remember the stories of mixing hydrazine in fuel cars?
