Traction
Turbo Mini Forums

Need a some advice please guys

I seem to struggle to keep traction while coming on boost, only running 10psi. Running A032 tyres and have the suspension set up correctly courtesy of Wil (again a massive thank you for that) and also corner weights set up.

I have done the different driving styles feathering the throttle to keep a nice smooth boost rise while this works i still would like to be able to use the power without it being wasted in wheel spin. Even when i am at 60-70 and i put my foot down i get traction problems. What would be my best options to improve this? I was thinking either larger wheels as i am running 10's at the moment although i like 10's for the looks or an LSD.

My current diff is whatever was in a standard 1993 mayfair so not sure what the ratio is.

Thanks
Nick

LSD would be a good start.

Can we not lobby a tyre manufacturer to make us some decent sized 10s??

Am I right in saying you have Sports Pack arches and 10's that fill them?

If so you are going to have wheels that have quite a big offset, these can cause handling problems.

Try some different wheels that stick out less (it may look shite) and see what you think. If its better then start thinking about changing your wheel/arch package.

If something is worth doing, it's worth doing half of.

Yeah i have sportspack on at the moment but they will hopefully be going when i replace my front end sometime this year.

My wheels are 10x6 ultralights. Can i borrow your wheels if they are smaller John for a test?

You can pop over and swap them over and back if you want.

If something is worth doing, it's worth doing half of.

I expect the answer will be to fit a LSD, but worth checking the condition of the tyres first? How old is the rubber? If you rotate the wheels off the ground, do the tyes have any noticeable flat spots from sitting in the same spot?

I Cleaned my bike tyres with white spirit and it stopped the back tyre from spinning up. There was no sign of oil or grease on the tyre so I was surprised when it made a difference and worth mentioning.

yoko's have been know for batches to require a lot of heat to get them working (old stock) check the date on the tyres and what pressure do you run?

my metro I only use 26psi up front and 22psi on the rear.

Searching is all you need on TurboMinis

Worth a look at tyre pressure. If mine are too high I end up with zero grip.

In the 13's at last!.. Just

A big thing to consider is the roads are crazily slippy right now and have been for a good few months. !!

I will check the tyres when i get home, pretty sure they are over 2 years old now but has decent tred left on them. Whats the average tyre pressure you guys run?
I reckon mine might be too high now Paul has just stated his.

Also the traction problems have been happening since August when i last used the car.

Do you have adjustable shocks? If they are set to hard that can cause traction problems. If they can be adjusted try them on full soft then on full hard and see what the differeance is. That said front to back firmness/softness can have a effect too.

I would say tyre pressures are a better starting point though.

9.85 @ 145mph

speed didn't kill me, but taxation probably will

Where are you driving? if its on the roads then suck it up till the summer comes, also I had more traction with good road tyres (dunlops, continentals, pirelli however were shit) than I had with trackday tyres Tried A048s and Kumho V70s. Youll need a 13" wheel though to get modern road tyres.

Traction issues? Join the club but i am blaming the road temp / weather conditions we have just had a couple days of belting sunshine here in doncaster but the temp has still been around freezing its not even been worth trying to put the power down
So much so im noticing a couple extra mpg about now !!

Yes i moved to the darkside

Instagram @jdm_brett

i would with those 10s if your sticking with them up the diff ratio to 2.95:1
and fit a ATB Quafe LSD

but if you want to fill those sports pack arches out, fitt 13s with 50 tryres, and stick with the 3.1 diif you have in the box now

review the rubber as the guys state above ................ still go with the Quafe LSD though

Out of interest, what clutch are you running?

Hmmm not sure what my clutch ever was. It's from the engine i got of Kappashitface

there is a gear calculator on 'guessworks' site that you can play with to give you a rough idea of the final drive fitted.

Well 4th is 1:1, so what speed are you doing at say 4000rpm in 4th ?

And what tyre size?

i would say around 60-70 of the top of my head.

165/70/10

Just had a quick count on a photo of my diff when i had it out, has 62 teeth and from memory was from a 1993 carb 1275cc Mayfair

18/62 gives 3.44 <--- probably this?
17/62 gives 3.65

+1 on tyre pressure mine have always been 28psi

Also what bhp You running?

Orrrr, you could just run more boost so power overcomes the traction problems
