Power PourDrag Racing specialists Webster Race Engineering have designed this additive specifically to increase the performance of normal super unleaded.

Highly tuned forced-induction engines, especially those running nitrous, traditionally produce very high cylinder pressures but treating 30-litres of fuel with a tin of this stuff allows you to run advanced ignition timing and gain more power without risking a meltdown.

It’s already proved its worth on many a race engine and is even safe for street-cars with catalytic converters. One of the most advanced fuel additives we’ve ever seen.
