Alloytec 190 acceleration
Im not sure if its just me or not, but is it normal for these cars to have weak acceleration when the car is cruising at around 70-80ish?
I was driving on a slight incline today and wanted to take off to overtake driving 75ish. I planted the accelerator and it was as if the gear didnt downshift to shoot but stayed in 4th or 5th and slowly crept up. I know this is probably why active select is good. I was hoping for a more responsive takeoff and havnt really tested it before.
Any thoughts as to whether thats normal for SV6's VZ Calais etc?
cheers!

should have kicked down to 2nd for sure, with the throttle pushed all the way down
Really... oh oh... hope I dont have a problem with my car.
Shortly after the post I looked up a similar car on utube and found this: Chevrolet Lumina (Holden Calais) (VZ) 80-120 (2) - YouTube
My car I think is similar to that being stock n all.
Im really interested to understand why your car would shoot from maybe 4th gear to 2nd when you do that though.
Im gonna re-test mine again next time and then again with Active select.
I think my next car has to be a V8 in order to get better acceleration at high speeds.
they jump from 4th to 2nd because thats what an auto does, if you have active select on (say your crusieing in 4th gear) and boot it nothing will happen you would have to click it down to 2nd or 3rd to get acceleration
Tells it like it is.
lol thanks guys!
Reasons for a manual, or even better a V8

in that video it downshifted to 2nd, so i cant see whats wrong with it, except the diff gears are a bit tall, get some 3.46 in your car and it should come out good as such in my video

whats the 0-100 time in that richard?
nm i just read the 120 = 100 part, i thought that was a bit too quick for a sv6
My alloytec is abit like that but maybe worse cause I have or had 2.8 diff gears in there.

slow acceleration due to gears and torque management

Solution, and you will be amazed at how simple it is. Get a manual the 6 speed lets you use the power easily. V8 is also another option lol
Donati..Whoa Green
The VZ SV6 diff ratio of 2.86 is piss poor for anything but economy. Bump it up (down?) to 3.45 or 3.7 if you want acceleration.

yea 0-100 acceleration is around the 6.7-6.8 sec in that video with all subs and spare still in car, only mods is twin 2.5 catback, 3.46 diff, 2 hole mod and mace manifold spacers
Nice mods Richard! And yeah, I think you're right in that it does shoot to 2nd gear. Im gonna test it out today with active select n see if active select lives up to what it should do.Originally Posted by richardpalinkas
My next car in 2-3 years will have to be a V8 .. hopefully a hsv. At the moment I do little driving and im happy with the VZ calais
^^ I think my stock Calais does 0-100 in around 7.2sec from what Iv read. People have told me whether I do it with active select or leave it in auto... that auto is better.
... tested it today. Its like slopes impact the gearbox decision as to change the gears or not, but today, on relatively flat roads, I certainly felt the gearbox shoot to 2nd after letting go of the pedal and the acceleration was exactly what I thought it should be. It picked up very well and very responsive
don't autos have hill sensors?? so the gearbox knows when to kick it back a gear
... I think you are certainly right in saying that. I drive along some pretty big slopes and notice massive differences between gear changes. Theres one slope in particular that the acceleration is just crap in auto, whilst on the next slope and roughly the same speed it fly's. The car does a pretty good job on flat roads nevertheless

Realistically an NA v6 is only meant to be able to overtake and tow, not what we want it to be. That's why there is the ss.

give everything a spray with wd40 wheels brakes that should fix the squeaks
yeah man... cept the VZ 190 is sorta like the VY supercharged cars and the kick you get in lower gears is still pretty good considering the 190 is in my opinion pretty well tuned.
Id get a V8, but I dont think the roads I use would allow me to enjoy it anymore than what im getting out of my 190. Nevertheless, I dont really like the look of the new VEs cept the E series in the HSV range. So yep, a V8 might be my only option in my next car
<-- Holden Towing Ford.
i noticed with my standard diff ration that kicking back to 2nd at about 60km's was always really slow. 60km's always seemed to be the dead spot. just outa torque bracket for second and to high for first...
You are possibly right. I do little driving and wont be using the car this weekend, but Ill test it out next week. but atm I still think my car picks up pretty good around 60 but can struggle on certain inclines as to whether downshift or not. Quite possibly cause of the hill sensors which Slipper proposed and I feel is right.
ding ding dinggg!!!
auto's should shift back gears when u put ur foot down hard. period.yeah man... cept the VZ 190 is sorta like the VY supercharged cars and the kick you get in lower gears is still pretty good considering the 190 is in my opinion pretty well tuned.

if ur in paddle shift mode, its up to u to select the gears, not the auto transmision.
if u had a manual, it'd be as easy as going from 4th or 5th straight to 2nd or 3rd n foot to the floor.
^^^ hence why i like driving a manual now. being there n done auto in 2 previous cars... got over that fast.
VZ SV6 now, Jelly?
I've had a very similar issue with the SV6 at that speed, except I get a real vibration throughout the car when I try to accelerate. It's ok once it eventually shifts down. Any ideas on the vibration?
