Re: Transformer arrives in Colchester
Great to see it back on the road Tim - I'll tell Gary the news when I see him in the next week or so! I hope he has no regrets about selling it and until the snow arrives, get out there and get used to it! After you've changed the throttle cable.

Yes Guy. It is taxed so thats the incentive. The sticky throttle cable is interesting as it gives quite a few unintentional kicks in the back.
more interesting is in the little run out I have just done I found it very twitchy as I approached the legal limit. I did not check the geometry/toe in until I was able to drive it, and it feels as the Americans would say - very loose. I suspect incorrect toe in a major contributor and also tyre pressures.
does anyone want to give me some pointers. It is a Transformer with Spyder chassis and 131 hawk uprated uprights, 15 inch wheels with 215 50 14 TB15 front and 295 40 15 TB15's rear. Currently 24psi all round.
Re: Transformer arrives in Colchester
No specific Transformer experience, but tyre pressures seem high.
Dropping them calmed Frederics Corse down. A little.....
Re: Transformer arrives in Colchester
Re: Transformer arrives in Colchester
Initial rough geometry check shows 3mm toe in and 1.5 neg camber on o/s wheel and .5 neg on nearside. Need to get turn tables to check castor....
Not as out as I had hoped....
Dropped front tyre pressure to 22psi. Is this low enough. Tyres I now see are 55 profile not 50 so a bit higher side wall. New and sticky though.
Also lost a litre of water somewhere in 20 odd miles. Explains why the fan came on as I got home but where has this gone as no leaks and engine ran absolutely fine. Could be the last of the air coming through the system while driving???
Re: Transformer arrives in Colchester
Still too high on front pressures.
you need lots of castor on the front.
Re: Transformer arrives in Colchester
I can see that the chalk line (or pyrometer even) technique might not be very useful if there are doubts about geometry/alignment but, besides the seat-of-the-pants method ...
Isn't there a way to calculate correct(ish) tyre pressures using a factor (of manufacturer's stated max pressure to max weight for the specific tyre) applied to the car's actual weight on each corner (or axle weight/2)?

Chris is 4 degrees as per Lancia spec enough. I am going to try to assess what I have today.

Re: Transformer arrives in Colchester
Thanks Phil
At this stage I would rather like to find out if we are in the right ball park and if not make some adjustment and see if this calms things down. I will want it done as accurately as possible in the final analysis, but who knows the right setting other than factory kpi10 camber -1 castor 4???
