I am going to the Zip Tie drags in Tucson next month. I decided to to do some practice launches, turned out to be a big fail.
The car;
1973 Charger weighs around 4000#
68 383 engine, mild cam 222/234 dur 467/494 lift, iron heads, dual plane intake, long tubes, short straight dual exhaust with turbo mufflers no X or H pipe.
Quick fuel 750 carb mechanical secondary's
4 speed manual trans
323 sure grip
29.4" rear tire
The engine is strong, the tires are sticky enough. The clutch is so so. Normal driving, throttle response is good, car runs well, shifts smooth, gets terrible mileage.
When I try to launch, staying out of the secondarys's, the car will move but not quick enough. So I tried more RPM, still not a hard launch. So I tried more rpm, in the secondary's all the way to 4500 RPM and dump the clutch, big smoke show from the tires. If I dont dump the clutch the clutch smokes.
Any ideas on how to get the car to launch better?
