Axel Tramp

Hey guys, I ran my car at the strip tonight, hoping to dip into the 12's. the best I could manage was a 13.3@106 (106mph indicates a 12.8-12.9??) but the car axel tramps everytime I change gears, meaning I have to let go of the accelerator each time. Anyone else have that problem? What can be done to rectify this? best 60ft was 2.0 on 18" 255 Good Year GD-S3.
Cheers

I'm told a good set of shocks should sort of most tramping woe's. I spoke to a few suspension guys about it because I'm having similar problems. Some also said having the wrong rear spring tension could cause tramping too.

Yeah, well Im not sure if its tramping, the whole car shakes, even water from the washer jets spit onto the windscreen. I have Tein colovers which were bought brand new, and are on the softest settings.

Tramping feels like you're going over lots of little speed bumps - but only on the back wheels.
If your water jets are going that sounds pretty severe! Did you try it before you installed the Teins and did it still tramp then?

KOFFEE, well done on the time, with that MPH it will go quicker, I have done 12.8 at that MPH.
The violent shaking you refer to sounds pretty bad, and having it occur on each gear change makes me lean more toward possibly a broken engine mount???
Did it tramp badly when you did the tyre warmer?
It may very well be tramping but I would have a serious think about a broken engine mount too.

Hey Koffee,
I had the same problems with my Ae112R sportivo turbo, but that's a front wheel drive so may be slightly different reasons. Mine only occurred when boost hit in first gear and the wheels started to spin. It felt like the dash was going to drop off into my lap 
Mine only happened when i put 16's on it (the original wheels were 15's and it'd spin freely without any tramp with them). Im guessing the bigger wheel made it harder to spin freely and therefore it bounced around.....i ended up getting new shocks & springs for the front (only KYB and kings) and that sorted out the problem. If you've got Koni's in there i cant imagine they'd be the problem though.
Like Joorsh said, if it did it before the koni's were put in and still does it then its most likely something else.....

it feels so bad when it happens  The steering wheel shaking like buggery honest you feel like the whole car will fall apart around you, and when you first see water hit the screen on the drivers side when the washer bottle is on the passenger side you really shit yourself.

maybe the problem is they tein's are to soft?
in my corolla i can overcome the tramp with more throttle, but i think thats only because it changes from having 50/50 grip to no grip at all

i have this on teh p00 car except its used to measure how fast you go around corners. I call it teh jizz0meter. the faster you corner the more fun the car is having hence the more bukkake shot towards your face.
at the moment im in talks with the fast and the furious 3 developers about incorporating it into their drift battle movie.
for all you fans heres a sneak peak, keep an eye out for "DANGER TO TEH JIZZ0METER!!" in one of the main scenes when the movie is released.
hope this helps

teh spine b0re was coined by gianttomato, the MK II Corona front seats are shockingly uncomfortable at best and they have this plastic stud thing in the middle of the backrest that after a while bores into your spine causing spasms.
Its there on purpose for our enjoyment of course and the aim of the game is to be able to regain control of the car at speed after you've had a spasm and reefed at the steering wheel.
here is a picture of gianttomato mid-spasm, notice even with puffy sheepskin seatcovers he still succumbs to teh sp1ne b0re!

to see what axle tramp feels like, boot it in reverse....
well, mine does it anyway.
the back just basically skips up and down, its horrible.
softer suspension *should* help.

Nope.
It's rarely to do with how soft or hard the suspension is. I have been in cars with boat like softness that didn't tramp and cars like mine are kidney jarring hard and don't tramp. I have also seen both hard and soft tramp like a bitch.
Some causes CAN be (but probably not the case for KOFFEE):
leaf spring wind-up
worn bushes
worn shock
tyres the shape of a hexagon

well in my case wth is it then, don't have leaf spring, new shocks, near new bushes new tyres. It actually got worse after replacing the old shocks and springs which were very soft now running a mild HD standard ride height springs, lot stiffer than before but not stiff.

Hhmmm online car doctor says:
Corona's should not be doing burnouts or being launched hard, when driven in the manner they were designed for i.e. sensibly driving to local clothes store to puchase a new cardigan no axle tramping will be present.

maybe get a diff expert to look at the diff pinion angle, may be the problem

Thanks guys. I think it may be the clutch, as the first time i ran, the clutch was brand new, now its 4 months or so old, and the friction point has gone much higher.

lol, that because your wearing your clutch out, which is very clear.
theres an s13 convertible here in perth that runs some very quick times, but axle tramps so badly the whole convertible part of the roof joggles and shakes, the plastic window at the back of the car flexs and jerks like crazy.
as far as i know, he hasnt been able to solve the problem.
he is a member of SilviaWA.com
theoretically, the back end hops because the wheel base is being compressed (the back wheels, pushing towards the front wheels, compresses the wheel base, and the back end hops back into position.
i wouldve thought softer suspension would help, because it would make the car squat somewhat and force it towards the ground.
consider strengthening the forward/backward movement of the back end, and improving grip (quick fix, drop a few PSI in your tyres).
check all bolts/connections to see if they're loose...
i cant think of anything else.
with all that ive said, i know im wrong somewhere, so please, be gentle.

site about stiffer mouter mounts to reduce/eleminate wheel hop.
http://www.raktron.com/misc/mt.htm
reference purposes only - i do not endorse this site
it's from spring compression/windup, and/or soft suspension & engine mounts compressing.

I've heard that in some cases the tramp can be caused by play in the pinion shaft bearing. The pinion trys to 'climb' the crown and as traction is broken it unloads, traction regains and then it happens again... Might even be made worse by installing newer/stiffer suspension components.
Never actually seen this but it might be worth a look.

i am now having the same problem on a hard launch with wheelspin in the soarer, you dont really notice it untill you put an engine and gearbox in the car that allows you too spin 1st through third 
I have a feeling mine might be the diff cradle bushes, but im gonna play with the preload and body adjustment on my coilovers tomorrow and see if that makes a difference...
dont think it will somehow but its worth a shot

isnt the diff center in a irs car bolted to the floor?
which would mean the angle wouldnt change?

Was this a comment about what I posted?
You are right, diff is bolted to the body of the car and pinion angle doesnt change with suspension movement.
