Id I was going to run the tttf class I would stick with nitrous! The class is designed for nos Cars. An f1 with no innercooler will not compete with a 600 in motor on spray. Jason Lee has the nmca record with a 5.13. Eight different cams and 5 different converters to get it at its best. Just my 
2010 Toxic Orange Challenger built by B and B Racecars! All aluminum R4/P5 engine, Proformance TH400 (3 speed) tranny, full Reid case, nodular 9" rearend, full Dragpak suspension, Protorque custom converter, BS3, PTE 85mm turbo, fire core wires, carbon doors, carbon front clip, and a whole lot more!
