lca poly/poly
relo brackets on lowest setting
chromoly adjustable tq arm pinion at -2
stock shocks/springs cut 1.5 coils front and back (lowered about 1 inch)
stock panhard rod
tires are at 18psi warm not hot
used to be a 3200 stall and 3.73 and i sprayed 125 shot at 4200 rpm
now its a 3200 stall and 3.42 and i flash the stall on the 125 shot with a wot switch
why are the tires chattering? it feels like wheel hop inside the car but the rpm is nice and the car feels like its hooking
has good weight transfeer front tires are just about off the ground...the rear isnt squatting too much either...leaves pretty level

yeah...at around 25 i coudlent hook we went to 20 and it was chattering them...went down to 18 warm and its still doing it....haveing tried any lower...should i?
think most people say try 25 and work down in 1psi incraments till it starts to slow down or spin then add 1 psi?

tttttt
changed a few things im goana copy and paste from ls1tech
well i got my suspension all in went to the track and i still have the same problem
midwest 9 inch 3.90 and spool
chromoly tq arm all rod ended except one small bushing right before the crossmember (this is set at -2.5) (originally it was set on the second hole from the bottom(instant center) then moved to the top hole))
wolfe drag bar set neutral then 1/4 turn extention on the pazss side
chromoly adjustable lowers set on lowest hole (barely angled up from front to back)
chromoly phb
stock springs with comp engineering shocks out back set on 50/50
afco coilovers out front set on 9 compression
i started the otehr setting at about 5 on loose then ended up all the way loose slowly adjusting through runs
mt dr on stock wheels set at 26 then 24 then 20 then 18 then 15 no chnge in traction
u cut a 1.65 60' on motor then went 1.61 was my best on spray flashing the converter on 125 shot
tires at 24 shocks at almost all the way loose about 80%
http://s21.photobucket.com/albums/b2...t=IMGP2057.flv
tires at 20 psi shocks are at 100% loose
http://s21.photobucket.com/albums/b2...t=IMGP2060.flv
tires at 15 and 100% loose
http://s21.photobucket.com/albums/b2...t=IMGP2062.flv
this all started when i did a major overhaul...changed from 3.73 posi and 3200 stall to 3600 3.42 and welded rear....ect ect......think it might have something to do with the spool and radials? i dont understand....maybe its that or i have a slight bent in the lip of one of my wheels (about 2 inch long flat spot) and maybe the wheels unloads in that one spot causing the tire to unload and put too much stress on the other making it spin back and forth...im goana try a new wheel but any other ideas? could the raidials and spool be a problem? maybe the tires arent the same size around?
or is it just too much for these tires (i have a hard time believing since ive been 1.49 60' before and now i cant get outa the 1.6's)
also whats everyones opinion on subframes necessary or no? once i put the wolfe bar on the cars still as could be...but some are saying i might need them...id rather not weigh the car down with them...
i looked back over madmans stuff and stopped doing john force burnouts i do a 2-4 sec burnout now...he reccomends this to have the tires within 25 degrees of track temp
thing that gets me is
tire pressure had NO change in the problem
pinion angle had no change) it was +2 on accident we changed it to -2.5 same problem
new shocks still there
new swaybar still there
new tq arm still there...
new lowers without the big poly bushings its still there...
i just cant believe i cant make it any worse and cant make it any better...the tires dont spin either like i would expect a drag radial to when you have problems.....im just at a loss...i only mentioned the dent in my wheel because i was under it today and saw it and didnt ever remember it being there...
