He didnt run nitrous on it.
Like said, me and my bro were round his constantly when this was happening as both cars were basically being done at the same time, matt was going to map them both on the same ecu etc.
Daves wasnt on race fuel, it did however have an additive. One of the guys who worked at AFR had a special mix they used in the cars. I never found out exactly what it was, but it wasnt pure racefuel. something they added into v-power.
Oh and if anyone wants to know it was a cruise manifold and an OBX red series td06 turbo .. lol.
