Just a quick question or 2, Do you use a separate fuel cell and system for N20 ? How much fuel does the N20 kit(s) use per 100hp shot ? Just for info, here in the UK at today's exchange rate, VP C12 is roughly $182 for a 19 litre drum. (5 US Gallons) or $36 a gallon. VP C23 works out at around $235 for a 5 US gallon drum. I use Avgas and super unleaded mixed 50 / 50, works out around $9.00 per us gallon. Thanks.
