made base map on desk, but will go to track to make drive in new engine, so will map in ~2-3 weeks...

[nervas]

some new tyres for timeattack (can't use slick there)

[Greg_S]

OMG, how wide are they!

[nervas]

here is video of car starting, getting finally ready for track tests

what tire dimensions do you got? and are they 888´s?

do you overheat the tires sometimes?

im gonna run 265, hopa that is enough for my cars weight and power..

it's 285/30 ... I haven't tried 888 yet. but couldn't make heat to slick HARD compound tyres.. max 60C degree.. It's very hard to make heat on quattro to rear tyres, we have to use aggresive toe settings

[lind4hl]

sounds good then!

what camber/caster toe(looks like pretty much toe in?) you´ve got on your car? im guessning one setting with slicks and one setting with r-tires?

you are right, different settings with slicks and r-tires. 888 requires more camber because of softer sidewalls.
Generally ~5 degree caster, camber ~-2.5/-3 front, -2/-2.5 rear, toe from 0mm to +-10mm depending on track and wanted heat to the tires

[lind4hl]

So little camber?? :confused:

generally most people in sweden drive 3-5 degrees camber on R-tires

im building up my car with this spec:

Front:

9 degrees caster
2-4,5 degrees camber
Toe almost whatever i want.

Rear

2-4 degrees camber
toe i can have how much i want almost.

Hoping this is enough adjustment...

[nervas]

I can adjust from 0 to 6 or even more degree camber, but you need to monitor your tires temp, that all 3 points should be ~+- the same temp.

[lind4hl]

exactly, strangely enough, people here have the same temp in the tires with so much camber, maybe our tracks differs alot..

here a short one lap video, of engine run in procedure

[pnanassy]

this is with no boost,right?

what Data Acquisition do you use/have

Thanks,Peter

[nervas]

mild boost, ~0.7bar max sometimes, but always looking at gauge not to overboost

Datalogging - AIM MXL Pista with AIM Smartycam connected to it.

Looks like the bonnet needs some fixing. It jumps up and down all the time
