TT2 Curborough Sprint
Turbo Mini Forums

Firstly, cheesrs for Bud666, T2clubby and Doodmeister for coming to support. They stuck it out right to the end, and I'm sure it was getting a bit boring.

Anyway to the event it's self:

No real competition in our class, just me, Ben and an ex metro cup metro (with no slicks and a standard 1.4 K motor). But today was a test/shakedown day, and boy was it worth having one.

On the first run the exhaust fell of; the down-pipe parted company with the turbo-elbow. My fault as I rushed to put it back on after changing the head gasket last week.

With that sorted we went out on a second run. this was abandoned on the first lap as it kept cutting out on boost. It turned out it was a blocked fuel filter. Although we cleaned it, there was obviously contamination in the tank, as it kept clogging up after every other run.

We solved it by empting the fuel into Doodmisters tank (we had nowhere else toi put it) and removing the foam. The foam appeared to be braking down and causing the dirty fuel. After this was solved the car ran fine for the rest of the event.

We still have a few niggles though, the car is very oversteery, which I'm sure is entertaining to watch dosen't suit either of our driving styles. It's purely a setup problem and we'll get it sorted. It also feels as slow as the RR results suggest.

Good stuff - I reckon you'll be back on form in no time!

Yep a good day was had by all.

Here is me:


And here is Wil going sidways again:



Wil turns into corners much harder than me and was affected by the oversteer more I think. Well that could explain why I beat him by a bout a second, something he forgot to mention. Another thing that came to light was that the rev limit was set to 6800 so that is why the power drops off on the RR after that. A bit of setup and bits and bobs should see it as a flyer.

Had a real good day out, thanks to Will and Ben for letting us hang around and drool over their car.

In the pics it looks awesome, in reality it is something else!

They both did some fantastic times, trouncing most of the more powerful cars by a long way.

Well done lads, cant wait to see it on more power.

most minis oversteer at that point at curburough. i have nearly come to greif myself doing the same thing,
and saw the Depper 's destroy there origional yellow mod prod at the same spot,by sending it into the bank backwards then skywards,

carlooks good though in action at last,
and what was the best time for you boys.???.

Had a great day out. The car is amazing, so much nicer in real life than in pics.

Cant wait to see it when its setup and making more power cos it was fooking steaming yesterday!

Congrats dudes you've built another goodun.

There were some other cool cars there aswell, the old standard SD1 was brilliant to watch for pure comedy sideways value, and that spaceframed fiat 500 with a 1380 A series in the boot looked wicked.

The pictures we taken by the bread knife with her new Canon 350D which she is learning to use. I am quite impressed tbh.

Good start chaps, keep it up.

I am sure you dedicated guys will sort out the niggels, that is what a shake down is about afterall.

Seems to have a fair bit of body roll, are you allowed to run antiroll bars?.

I am sure with some suspsion geometry tweeks it will all come together.

Good luck.

We've got the hardest rubber doughnuts known to man on the front and it still rolls. There is an ARB on the back. Maybe a front one as a future mod.

It is actually very controlable, and we don't want to dial out the oversteer completly as it's great round the slower corners.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

It is amazing from pictures how much a car that FEELS very flat in cornering is actually rolling when you capture it in a static photograph.

I'd personally be looking at the rear toe settings as a starter for ten, I won't put any more detail up here as I am sure you guys know which direction to be going in with it. Possibly a change to camber settings with the slight roll it is displaying in the pictures may be advantageous as well.

The reat toe is currently set straight ahead. and unfortunately, for whatever reason, this is as close to any toe-in that can be achieved. I'm suer that we CAN get more but it'll involve changing the brackets I think.

Raising the rear is what we are planning, this can have dramatic affects on undesteer/oversteer.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

The basic plan is to re-do the corner weights and put more on the rear to calm the rear end down. This should help the front roll to some extent as we will be able to up the arb on the rear. Something like that any way.

We really need a few more events to get it sorted. The overstear was somewhat exagerated as the new tires on the back needed scrubbing to get rid of the release agent, it did calm down as we got more miles on it.

I to prefere a bit of predictable oversteer, simply turn into it with some more loud pedal and if the balance is correct a four wheel drift occures with no major loss of momentum.

Tel me abot new tyres!....the Yoko 539's i tried at the weekend were super new shiney and slippy...all a good edjucation!

JF.

she does look good guys!!!
You have the same problems as me last year, loads of oversteer. My head went porous before I had time to fix it. would be interested to hear how you get on.

Team Racing

oversterer was a big prob for me in my lightweight when i was on the hill stoo, usually only the first corner on stone cold tyres, ,,it used to annoy the hell out of me to have to go into the first corner steady to avoid greif.
you need to fit small flame throwers under the rear arches to warm the tyres [without the scroteneers finding out of course],lol

I've got a set of polly springs in the garage. I bought them second hand, so I'm not exactly sure what I have, anyone any ideas?



Any way I fitted the smaller ones to the front and a 'jump test' on the subframe led me to believe that they were softer than the rubber donughts I have.

I'm interested to know about the results of parallel rear tracking, we've run it like this for years on the old car and it was very well balanced.

I could be wrong but from the video it sounds like you brake, changing down, turn in, get back on the throttle and then back out again?
