thoughts on this combo
thoughts on this combo Ok, this is my friends car and the times he is running seem slow for what he has done to it.. I dont know if the tune is that far off or maybe his combo is wrong.. Just looking for some suggestions on what he can do. Here is the combo.
99 Trans Am Ws6 - full interior, full acc, t-tops and no weight taken out
Stock bottom end
double roller timing chain
LS2 Professional Products Intake
Holley 90mm tb
SLP Lid w/k&n filter
SLP 85mm mass air
Kooks 1 7/8s LT wit 3in y-pipe(no cats), into magnaflow catback
Untouched 243s
T-rex cam
42lb injectors
125 nos wet single nozzle kit
Mail order tune from thunder racing
T-56(spec 3+clutch, upgraded internals, pro5.0) with strange 12 bolt with 35 spline axles/spool and 4.56s and billet specs 15x10 with 28x11.50x15 hoosier quicktime pros..
suspension is spohn control arms, adj pan hard bar, v6 springs, torque arm, tranny crossmember..
car has best of 11.28 at 123 i think that was the mph with btw 1.5-1.6 60's
shouldnt this car be going faster? is it all in the tune or do the parts not mesh well together? Anything you would change or things that he can look at first or should it go straight to a dyno and get dyno tuned?
I think i posted this in the right section cause my question is about motor combo, but if its in the wrong section i apologize and it can be moved to the correct location
