info on shock settings
Hi GUys
I am looking for some reading info on setting up shocks...i have single coil over adjustable qa1 same shocks on the front.... a ladder bar car and also affetcs of tire pressure...just trying to do some fine tuning and if i have a referson to go by will help out........trying to fiure out why the car is loading and unloading, does a spin on the tires, so not sure about stiffening the shocks or lossening them , go up with tire pressure or down...more i think about it the more i confuse myself..........thanks in advance.

tranny is a 1.76 powerglide
motor is 383 sbc peak torque at 5300 rpm 525 ft/lbs
peak hp is at 6700 rpm 600 hp
car is 55 wieght to front and 45 to back
The other day i was playing with my shocks and tire pressure and my 670 foots went in the range of 1.38 to 1.42.......our track elevation is 2400 feet and usually corrected in the 3600-4200 range and as bad as 5300 feet
two weeks earlier i took the car to the coast and air was at 1400 corrected the worse and i ran 8 psi in tires and still would load and unload but not as bad with 1.34 60 foots.
So the biggest thing is should i loosen up the front shocks right up and tighten up the backs and go up with tire pressure and try elimanate the load and unload of the tires.....................thanks in advance

I would try running more pressure, keep going up by a 1/4-1/2 lb until you get it to spin and then back down and see what happens. I had a similar problem and it ended up being the tires, put on a new set and it was cured.

Fishman,
If you car has a lot of seperation at launch it might be running out of travel on the rear shocks causing a spin situation as you described. Is there any way you make a shock travel indicator and just make short launches to check it? They are not to tough to make.

Iwas talking to a fellow today that runs a top fueler and he told me a few things, he figures that i am wadding the tires and that i am running my rear shocks to tight as they were set on 8 clicks stiff out of 12 settings, he told me to just play with the rear shocks settings and the tire pressure this weekend and after my first pass give him a shout...........also we were discussing the back end of the car is higher then the front end..........the tire shop has a blow out sale on a set of mickey thompson front tires for $80 a piece and they are 2 inchs taller then mine...that might stabilize the load more or make it worse............front shocks settings are 5 clicks
