If it were me:
1. I would start my tire pressure off at about 18lbs. The more pressure you can run while still hooking, the faster you will go. Play with it, find out what works. Less psi will help it hook, more psi will help you on the top end. Find a sweet spot.
2. In my experience, 10lbs is a good starting point. I would get a reliable person to watch my launch. If the car leans bad, I would add a few lbs of air to the bag, and continue untill it launches nice and square. (I'm sure you know this, but a drag bag is kind of a band aid, but they work)
3. I would raise the launch RPM untill it stopped hooking. More than likely, if the suspension is doing its job, and the track is good, you could just about launch it off the limiter.
4. Shifting is something you have to play with. For the most part, shift a couple hundred RPM above peak hp.
5. I never run n2o below 3000rpm's because it puts alot of stress on the engine. A 150 shot is a 150 shot no matter what RPM your at. Cylinder pressures shoot through the roof at low RPMs on the bottle.
6. Whatever RPM I shift at is where I would kill it.
I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them. -
