Title: Car spins up with ease
Post by: MoMartin on 11 December 2014, 13:29
Hi, I've got an AGU that's been remapped by rtech (between 190 and 200 bhp) and it seems to me that everytime I go to pull away in the wet (doesn't even have to be that wet) the wheels just start to spin up, I've tried it with half throttle, letting the clutch out slowly, basically everything, it just doesn't seem to hold its grip. I also have decent tyres on the front and back (Michelin on the front and continental on the back) so I was wondering if there's something else it might be thats causing it to spin so easily.

Any information will be appreciated.

Thanks, Mo

Worn or improper suspension setup can exacerbate the problem. Maybe try to ease off the throttle some, half throttle is quite a lot.

I have fk coil overs, but I bought the car with them installed, so I have no idea how old they are. Since buying the car I've made the car completely level (arch to floor) and it isn't particularly low either.
As for the throttle, I think that even half throttle was a bit exaggerated, I've seen little 1 litre cars pull away faster than me without spinning up. I really have to ease off so much to stop it from spinning.

Could jack the car up and check for play from various bushings, shocks can be checked with ease.
On the factory setup I didn't use much/any throttle to move off really, can't really do that now with my current setup but wheel spin when moving off isn't so much an issue with less grunt low down now.

I find it vitually impossible to get any power down in slightly damp conditions and yes 1 litre cars have also left me at the lights :angry: but if you have the grip in the dry i wouldn't of thought your set up was at fault.

I'll have to have a play when I next get the time. It's not too severe, but it's just a bit off putting especially when I'm sitting at a roundabout waiting for a gap, a gap finally comes along, I go to pull away and all I do is wheel spin.

I still have grip in the dry, but it does seem to spin a bit in first still if I really put my foot down. I can put that down to power though.

Never fond of low down power for the above reasons, fwd in unfavourable conditions are at a disadvantage. Shifting the powerband up helps make it more drive able I find, wheel spin is significantly reduced in the low rpm.

Yeah I kind of wish i had a higher up power band now, because now that i live in Manchester, basically all the power my car has just cant be used  :angry:

thankfully I don't get these issues  :whistle:

Have you done any handling modifications?

car has a few but the 4 motion bit helps most  :smiley:

4-motion would be nice, I got my sights set 4motion, even with my suspension setup it's struggling to put the power down.

I was gonna ask if it was a 4motion, but then i thought maybe you were just saying that your car just didn't wheelspin in the wet, and that our cars had a problem :grin:

I don't think I'll get wheel spin off the line with haldex, I'm wondering whether it would spin up at the top end when the turbo comes alive. What I'm thinking is, it'll be a hell of a lot better than fwd and I've seen that the haldex system can be made permanent 4wd and more torque sent to the rear than oem - using an aftermarket haldex controller. It's all very appealing but does mean I have to go through the effort of buying another LSD for the 02m unless the Quaife diff from the 02j is compatible with the 5 speed 4wd gearbox.

mine will still spin for a split second on full power but it has a 4motion controller and when i change the setting it wont spin even on full throttle and with kw3 coilovers its like glue until you strip the tyres  :grin:

Do you not keep haldex in permanent 4wd mode all the time? I worry how reliable the haldex system would be when left permanently engaged on a big turbo setup

I run Avons on the fronts because of this issue, I need to get the power down gradually

I'm guessing here but I assume we're talking of semi slicks. I also run semi slicks all around but still find it breaks traction up to 80mph in the dry. Think I need a better compound, ideally 4wd.

But with the big turbo (ish) going on this month I'll see if the lagg helps.

It's December and it's cold (well for the UK).

I just put Avon winter tyres (205/55/16) on my mk7.... the Dunlop summer tyres (225/45/17) spun in first and even second if you went on the throttle in any but a very careful manner. With the narrower Avon winter tyres I can hit 4000rpm (TDI :D )  in first without the wheels spinning..... all down to the tyres as summer tyres are sh!t below 7-10 degrees (depends on make and composition) as they get rock hard compared to winter tyres.

Also massively reduced the ABS kicking in when I really push it hard  :whistle:

Must be the road surface around this part of the UK and the south-east, I should have mentioned that my observations were based on summer conditions in the dry. In bad conditions it will spin up 5th (out of 5th) no problem. I should be running 255 width given my power to weight, especially with the power I'll be putting down soon  :undecided:

Have to count the pennies  :whistle:

My mate has a 5 speed 4wd box laying around his garage and he's been planting ideas in my mind, it would be nice to be able to keep my spec stage 3+ clutch and flywheel kit, but I'll still need to sell my LSD gearbox and find a 4motion shell.

I expect to be a little over 400bhp per ton in January and know there are many running much much more power through their front wheels with no problems but they tend to be drag cars running drag radials. Mine on the other hand is intended as a street/track car, so I'd like for mine to work on the road.

Mine tends to wheel spin in the wet, can easily spin wheels all way into 4th however for a good start i need to be so careful not to spin the wheels but once I start moving I apply more power and after second I can lay all the power down nicely.  :grin: :tongue: :evil: :evil:

Aha apparently when I bought the mk4 it's supposed to have 200bhp, but had acceleration problems when I bought it diagnosed the problem to be .5mm gap too wide on the spark plugs, then stage 2 clutch also. She pulls so much better now. Starting to believe all those ponys now :p
