Good time sschung...Are you still using the stock clutch? Is the car still having those running issues? Did you sping the tires lots or just a bit?

stock clutch as far as i know (haven't opened the tranny yet). it must be almost new as it doesn't slip.

car still has some issues. i'm working on it, but progress is slow...

some runs i didn't spin the tires (not recommended) and some i spun too much (didn't get full traction thru all of 1st gear). i've got to find that sweet spot where it'll spin enough not to bog, but still hook up ASAP. for me i think it's somewhere between 2500-3000 rpm using a clutch dump.

VHT trackbite + new sticky tires (an LSD would help too)

That'll solve your 60 foot time, but will require probably a 4,000 rpm launch to not bog.

But I wouldn't dump the clutch on anything that didn't have a whole lot of drag slicks behind it. Feather the clutch to get traction.

As for getting your r/t down, launch when the last light is still lit up. This is the biggest hurdle to get over as a drag racer. It will seem like way too early,

If you're still too slow r/t wise, try and launch when the second last light is still lit.

Basically try a couple non-variable ways. You'll either red light or be slow or be close. Then you can build yourself your own "I launch when" for consitency.

For your first time out, running a 15.3 in a car that still has bugs ... damn.

First time I hit the track I ran a 16.6. Heh, eventually without changing anything other than technique I shaved about 4 seconds off that ;)

^^^
you run a 12.6 on the 200 or the charger?

Mr.200date not saved · #8

heh ... neither.

My first car, a 63 Pontiac Acadian with a 383 stroker went into the high 11s.

Then they kicked me off the track ... bastards.

Slow reaction time, that made me mad, so I over gassed, spun ... man, embarassing.

Charger's only barely into the 13s on streets. The 200 ... I shudder to think ... in its present state, maybe high 18s?

Don't worry, we will have your 200 running properly soon enough...8) (praying to god that it will be something cheap that broke) 8)
