Need help with ladder bars on Chevelle I am having trouble getting my car out of the hole the car is launching getting up on the tires and after the car is wheels up and then about 6" into the run it just blows the tires away. I need some help from a chassic guy I'm hoping that someone in here can help direct me.
From everything that I've read I should move my bars up in the front.
Should I?
The best 60 with this setup is 1.38 car has gone 8.93 I want to run the 8.5 index class but I need the car to have more control out of the hole.
not sure if i'm just plain over powering the tires or not, motor make 750hp and I'm putting a 36/32 n2o(approx 400 shot) tuneup in it from the hit. I'm switching to slicks for next year.
I have comp eng ladder bars on my chevelle, koni double adj shocks, m\t et streets 30" x 12.5, my car weighs 3240, I have 850lbs on each back tire, so i'm back half heavy (optimal or at least I thought)
My ladder bars are dead level, pinion angle is 3 deg down and my shocks are as loose as can be and the looser I make them the better the car gets, problem is I can't go any futher.
some help here guys should I just two stage the n2o or can I get 1000 to 1200 hp to the ground with the 30" x 12.5 tire.

I just looking to get some help with chassis tuning mainly the ladder bars. I know that there are not alot of people in here going that fast but there are some. I know how to make the power just not real good at applying it.

Up makes it kill the tire at the hit but looses force down track. Down hits the tire picks up more weight and keeps the weight back for longer. Everytime you move the bar the shocks adjustments change. I run the extension tighter with the bar uphill and looser with it downhill. The compression is used to keep the tire from bouncing back up into the car after the tire wads up.
