get rid of weight-----alum heads/manifold, alum radiator, water pump, take out big truck seat ( get a single race seat), fuel tank( replace with a small fuel cell), take out/off airconditioner, power steering, radio, front brakes, lighter wheels/tires, different lighter rear end / springs/shocks, eliminate exhaust system, change window glass to lite weight lexan, if your heavy, get a light weight driver, grill/bumpers, driveshaft--look into if anyone makes fiberglass body parts, fenders/doors

weight your nitrous tank to make sure it has enough for a run ( I used to change 10 lb tanks every two runs and refuel gasoline runs in between runs--- check valve gaps and jetting/plugs every run-record data so you'll know what you did and if it was consistant------make changes A-B-A style
