[QUOTE="rdsnk46, post: 14661961, member: 28757"] I like to keep as many variables constant as possible. Fuel level- half tank Tire pressure- 19 psi is what M&H recommends but I had better results lower. Pick a launch RPM and see how it works, start @ 2500 rpm and work up and down. Always run in the DR/slick lane never in the street tire lane, let the big tire cars literally pave your way with rubber. If you have a bad track surface you'll have to adjust Like anything practice makes perfect. Factory 3.31 and 20" tall wheels and tires are not a great combo- 3.73 would be better suited with a 28" tall tire like the M&H your running. I shifted my 5.4 @ 6800 rpm religiously I would think the 4.10 might be a little short on the gear but if you can hook it then it's all good. Burn out- I like to clean the tires off in the water and use the spin momentum to carry me out of the water. Then start my burn outside of the water box. With 4.10's I'd use second gear. Launch technique- Don't push the clutch pedal all the down at the starting line. Ease into pre stage and slightly depress the clutch until the car stops moving. Now pre staged, rev motor to launch rpm, slowly release clutch and ease to deep stage with rpm at launch point but only push the clutch in to stop forward movement, not all the way down. Launch from the point of friction..... [/QUOTE]
