Teesside Autodrome trackday 2011
arrived at teesside autodrome at 8am but the staff who registers the car drivers aren't in yet
registered at 8.50 short briefing and then out for 3 intro laps before session commences
dad stopped filming after 1st lap cos he was holding onto cam and would get nauseous if he was looking at the screen rather than the track.
brakes and tyres take bout a lap to heat up so to em easy at first.
after 3 laps session would continue cos the leading guy has pulled in but some ppl were abit hesitate at first if they could overtake yet.
the damper hardness were at 66% front and 0% rear. with dads extra 95kg in the left side, it understeers abit during the last medium fast 180deg right hand corner and the demanding twisty uphill mid sections. at the 1st hairpin its ridiculously bumpy as the car bumps all over and loses some traction.
1st session ends for the bikes next.
tyres pressures gone up from 1.85/2.2/1.35/1.0 fr/fl/rl/rr to 2.18/2.53/1.53/1.11bars
i experimented with 100% hard dampers all round on the 1st proper run
car session delayed till 10.30am abit cos a biker had crashed.
trackside view
car is alot stiffer on fast bends but on bumpy slow corners especially the 1st hairpin the harder front damper loses traction.
so i set to 66% front and 100% rear to try regain front traction.
the camera battery died on me 3rd run but the car felt abit better. understeer is still there if pushed too hard. exiting the corners the lsd def helps to put the power down but as with any fwd the tyres could only put down so much.
brakes have now got a nice transfer area after few hard laps. once brakes n tyres are fully hot i progressively dared to brake later n harder every time i go down the straights doin 70-80 and tis unbeliable how fast it decelerates down to 40 from where the darker skid marks appear at bout 50m point, almost tears ur face off. tis only limited by how hard i can press the brake and the abs rarely engages except if it hits a bump.
biker session was next followed by 1hr lunch break so we went out for lunch early. went to start car and the ign lights wont turn on. oh ffs prob sticky ign switch again. took it out, wiped contacts clean, reassemble and its starts ok. think i need to replace this old switch.
had a nice kfc in the lush sun.
car session commenced at 1pm. took dad along.
dad commented later that he didn't feel as much umpth up the hill n straights compared to turbo cars he's driven before, as though it was like my old janspeed system.
i was unaware of it at the time till we finished the day but what actually happened is that at one point the pipe from the IC to AFM had once again blown off loose so only 4psi of boost was going through (so making only say 110bhp) hence why it just accelerates like the janspeed system and why you could hear the leaking hiss down the straights when it goes above 4psi.
back at pits the loaded FL tyre is shredding down towards the min mark so i swapped the FL & RL wheel.
entire alloy, tyre & nuts are really hot to touch so much that the centre cap just fell off loose when i removed the front wheel. gonna need to figure a better fixing solution for it.
nice brake transfer layer
going out on track the fuel dropped from abit down to red so had to go back out to a local shell to fill up.
cos of the transfer layer on the brake discs the cold discs really felt like stone, especially going back onto the public road.
this is the 4th run after swapping the tyres and filling up.

car felt great, track is almost empty and real grippy hot. blown away by the pulsar brakes at end of straights and found i could take the 1st fast left corner in 3rd WOT, cut the apex and it grips.
dad videoed that corner

afternoon run on a hot empty track pushing the car is the most fun period of the day.
car in one piece. lettering on the toyos are half gone especially the RH which is the heaviest and has the lowest tyre pressure
fantastic day(Y)
